"All things at once":  A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals (open access)

"All things at once": A Retrospective Qualitative Examination of the Parental Racial Ethnic Socialization Practices Experienced by Multiracial/Multiethnic Individuals

The purpose of this phenomenological study was to explore how individuals from different multiracial/multiethnic groups experience and process the phenomenon of parental racial ethnic socialization (RES). Critical multiracial race theory, critical race theory, and bioecological systems theory offered a conceptual framework to how RES is often presented and processed. This study was guided by two research questions: (1) What are the experiences of RES among multiracial individuals? and (2) How do multiracial individuals process the parental racial ethnic socialization they were offered? Nine qualitative, one-on-one, semistructured interviews were conducted with individuals from three different multiracial/multiethnic groups. Results revealed that experiences of RES varied along with how participants processed RES. Three subthemes and one theme emerged related to the RES experiences of participants. For some participants lack of conversations were evident in their RES, which meant that conversations surrounding multiraciality and other racialized topics were not present. Other participants disclosed the subtheme of preparedness as part of their RES experience, while others mentioned the importance of environment to their RES experience. Additionally, the theme of changes over time arose, demonstrating how different life events can impact RES experiences. As for how multiracial/multiethnic individuals process RES experiences, the main theme of identity …

Bringing Them Back: Using Latent Class Analysis to Re-Engage College Stop-Outs

Half of the students who begin college do not complete a degree or certificate. The odds of completing a degree are decreased if a student has a low socio-economic status (SES), is the first in a family to attend college (first-generation), attends multiple institutions, stops out multiple times, reduces credit loads over time, performs poorly in major-specific coursework, has competing family obligations, and experiences financial difficulties. Stopping out of college does not always indicate that a student is no longer interested in pursuing an education; it can be an indication of a barrier or several barriers faced. Institutions can benefit themselves and students by utilizing person-centered statistical methods to re-engage students they have lost, particularly those near the end of their degree plan. Using demographic, academic, and financial variables, this study applied latent class analysis (LCA) to explore subgroups of seniors who have stopped out of a public four-year Tier One research intuition before graduating with a four-year degree. The findings indicated a six-class model was the best fitting model. Similar to previous research, academic and financial variables were key determinants of the latent classes. This paper demonstrates how the results of an LCA can assist institutions in the decisions …

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy (open access)

Coaching Athletes with Post-Traumatic Stress: Exploring Trauma-Related Competencies and Coaching Efficacy

The purpose of this study was twofold: (a) assess cycling coaches' trauma-related competencies, as measured by trauma knowledge (i.e., trauma-specific education, familiarity with post-traumatic stress [PTS]), stigma of persons with PTS (i.e., fear/dangerousness, help/interact, forcing treatment, negative emotions), and interpersonal skills (i.e., self-reported emotional intelligence, perceived quality of coach-athlete relationships); and (b) examine the influence that trauma knowledge and stigma of persons with PTS has on coaching efficacy specific to coaching trauma-impacted athletes (i.e., trauma-informed coaching efficacy), after controlling for general coaching experience. Descriptive statistics indicated the majority of coaches had no trauma-specific education, a high degree of familiarity with PTS, and a low level of stigma via four attribution variables. Moreover, participants highly appraised their own emotional intelligence, the quality of their coach-athlete relationships, and their trauma-informed coaching efficacy. A hierarchical regression analyses indicated that familiarity with PTS helped to explain additional variance in trauma-informed coaching efficacy over and above demographic and general coach experience variables. The study establishes trauma-informed coaching as a distinct area of research and highlights the need for improved continuing education opportunities for coaches related to psychological trauma and PTS.

Comparing Three Approaches for Handling a Fourth Level of Nesting Structure in Cluster-Randomized Trials (open access)

Comparing Three Approaches for Handling a Fourth Level of Nesting Structure in Cluster-Randomized Trials

This study compared 3 approaches for handling a fourth level of nesting structure when analyzing data from a cluster-randomized trial (CRT). CRTs can include 3 levels of nesting: repeated measures, individual, and cluster levels. However, above the cluster level, there may sometimes be an additional potentially important fourth level of nesting (e.g., schools, districts, etc., depending on the design) that is typically ignored in CRT data analysis. The current study examined the impact of ignoring this fourth level, accounting for it using a model-based approach, and accounting it using a design-based approach on parameter and standard error (SE) estimates. Several fixed effect and random effect variance parameters and SEs were biased across all 3 models. In the 4-level model, most SE biases decreased as the number of level 3 clusters increased and as the number of level 4 clusters decreased. Also, random effect variance biases decreased as the number of level 3 clusters increased. In the 3-level and complex models, SEs became more biased as the weight level 4 carried increased (i.e., larger intraclass correlation, more clusters at that level). The current results suggest that if a meaningful fourth level of nesting exists, future researchers should account for it using …

Creative Self-Efficacy and Personality: From Imagination to Creativity (open access)

Creative Self-Efficacy and Personality: From Imagination to Creativity

Imagination and creative self-efficacy are important components of the creative process and outcomes but are rarely investigated together. To explore the relationship between personality factors, imaginative thinking, and creative self-efficacy, survey responses were gathered from university students in a southwestern region in the United States (n = 1,731). Personality was measured using the International Personality Item Pool (IPIP), imagination was measured using the Imaginative Capability Scale (ICS), and creative self-efficacy was measured using items based on reliability in previous studies. Participants were asked to complete the three surveys along with demographic information through an online format. Confirmatory factor analysis (CFA) was conducted first to confirm measurements used. After fit indices confirmed measurement models used, subsequent analyses were conducted using structural equation modeling (SEM). The model of best fit supported creative self-efficacy as a strong predictor of all three factors of imagination. Additionally, the model indicated a strong relationship between conscientiousness and conceiving imagination as well as other notable relationships with personality factors.

Developing a Self-Respect Instrument to Distinguish Self-Respect from Self-Esteem (open access)

Developing a Self-Respect Instrument to Distinguish Self-Respect from Self-Esteem

Throughout the scientific literature, researchers have referred to self-respect and self-esteem as being the same construct. However, the present study advocated that they exist as two distinct constructs. In this quantitative study, an instrument was developed to measure self-respect as a construct, and subsequently distinguish that self-respect is distinct from the construct of self-esteem. Exploratory factor analyses (EFA) indicated 32.60% of the variance was accounted for by the 11-item Jefferson Self-Respect instrument (JSR), which measured self-respect as a unidimensional construct. The reliability estimate of the scores from the JSR reached an acceptable α = .82. Fit indices (RMSEA = .031, SRMR = .037, CFI = .982, and TLI = .977) from the confirmatory factor analyses (CFA) signified a well-fitted hypothesized model of self-respect that existed as a unidimensional construct. Additionally, the CFA revealed that the construct of self-respect, and self-esteem was generally distinct, and the strength of the correlation between the two constructs was moderately positive (r = .62).

The Effect of Co-teaching on the Academic Achievement Outcomes of Students with Disabilities: a Meta-analytic Synthesis (open access)

The Effect of Co-teaching on the Academic Achievement Outcomes of Students with Disabilities: a Meta-analytic Synthesis

Co-teaching has been, and continues to be, a growing trend in American schools since the late 1990s. As the popularity of this service delivery model increases, there is an imperative need for empirical research focusing on how co-teaching affects academic outcomes of students who receive special education services. Evidence regarding the academic outcomes of co-teaching is limited, and reports mixed results. The purpose of this study is to provide a synthesis of research examining academic outcomes of co-teaching on students who receive special education services. Quantitative information from each research report was coded, an overall effect size was computed, and a moderator analysis was conducted. Results suggest a significant effect (g = .281, k = 32, p < .05) of co-teaching on the academic outcomes of students with disabilities when compared to students with disabilities who did not receive instruction in co-taught settings; though a larger effect was found among dissertation reports (g = .439, k = 25, p < .001). Additionally, a significant effect was found when examining the academic outcomes of students in co-teaching compared to the academic outcomes of students in a resource classroom setting (g = .435, k = 27, p < .001. Lastly, effects were …

Evaluating Program Diversity and the Probability of Gifted Identification Using the Torrance Test of Creative Thinking

Multiple criteria systems are recommended as best practice to identify culturally, linguistically, economically diverse students for gifted services, in which schools often incorporate measures of creativity. However, the role of creativity in identification systems and its recruitment of diverse student populations is unclear. The Torrance Test of Creative Thinking (TTCT) is the most widely used norm-referenced creativity test in gifted identification. Although commonly used for identifying talent, little is known on the variability in composite scores on the TTCT-Figural and student demographics (i.e., race/ethnicity, sex, socioeconomic status, English language learning status). This study evaluated student demographic subgroup differences that exist after the initial phase of an identification process (i.e., universal screening, referrals) and examined the relationship among student demographics (i.e., race/ethnicity, free/reduced lunch status, English language learning status, sex), cognitive ability, academic achievement, and creativity, as measured by the TTCT-Figural Form A or B, to the probability of being identified for gifted programs. In a midsized school district in the state of Texas, findings indicate several demographic differences for students who were referred or universally screened across the measures of cognitive ability, academic achievement, and creativity. However, there were lower differences when using the TTCT-Figural. Results of a hierarchical generalized …

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8 (open access)

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8

This study was intended to evaluate the impact of socioeconomically disadvantaged children's participation in the Texas Home Instruction for Parents of Preschool Youngsters (TX HIPPY) Program on their school readiness and academic achievement. The study used a quasi-experimental design and applied full and optimal propensity score matching (PSM) to address the evaluation concern of the impact of the TX HIPPY program on HIPPY participants' academic achievement compared to non-HIPPY participants. This evaluation targeted former HIPPY participants and tracked them in the Dallas ISD database through Grade Levels K-8. Data were obtained by administering Istation's Indicators of Progress (ISIP) for kindergarten, TerraNova/SUPERA for Grades K-2, and State of Texas Assessments of Academic Readiness for math and reading (STAAR) for Grades 3-8. HIPPY and non-HIPPY groups were matched using propensity score analysis procedures. The evaluation findings show that the TX HIPPY program positively influences kindergarten students to start school ready to learn. The findings of math and reading achievements suggest that HIPPY children scored at the same level or higher than non-HIPPY children did on math and reading achievement, indicating that TX HIPPY program has achieved its goal of helping children maintain long-term academic success. However, the evaluation findings also indicated that …

Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation (open access)

Factor Retention Strategies with Ordinal Variables in Exploratory Factor Analysis: A Simulation

Previous research has individually assessed parallel analysis and minimum average partial for factor retention in exploratory factor analysis using ordinal variables. The current study is a comprehensive simulation study including the manipulation of eight conditions (type of correlation matrix, sample size, number of variables per factor, number of factors, factor correlation, skewness, factor loadings, and number of response categories), and three types of retention methods (minimum average partial, parallel analysis, and empirical Kaiser criterion) resulting in a 2 × 2 × 2 × 2 × 2 × 3 × 3 × 4 × 5 design that totals to 5,760 condition combinations tested over 1,000 replications each. Results show that each retention method performed worse when utilizing polychoric correlation matrices. Moreover, minimum average partials are quite sensitive to factor loadings and overall perform poorly compared to parallel analysis and empirical Kaiser criterion. Empirical Kaiser criterion performed almost identical to parallel analysis in normally distributed data; however, performed much worse under highly skewed conditions. Based on these findings, it is recommended to use parallel analysis utilizing principal components analysis with a Pearson correlation matrix to determine the number of factors to retain when dealing with ordinal data.

Flipping Scripts: Mentoring for Secondary Readers (open access)

Flipping Scripts: Mentoring for Secondary Readers

Researchers have reported that a variety of socio-cultural interventions can be used to increase positive attitudes toward reading for secondary students. A socially constructed reading intervention could add learning growth for a reluctant reading population. This study examines whether secondary students experience a measurable increase in positive attitudes toward reading after engaging in modeling and mentoring sessions with a much younger student and whether there is a perceivable difference in the secondary students' attitude following this mentoring activity. A variation of the one-way ANOVA, the Mann-Whitney U test, was completed to determine whether there was a statistically significant difference between these groups of students after participating in the reading intervention plan. It was determined that a small increase was found in one of the domains. The measurement survey is divided into four measured components that align with Albert Bandura's model for self- efficacy. The results from this study indicated growth in only one of the measures, however, some of the outcomes in the other measures suggested potential growth in attitudes with a relaxation of these necessary experimental strictures. A limitation of this research was the change from face-to-face tutoring completed by the secondary student with elementary students in an afterschool …

Lived Experiences of Families of University Students Amid a Pandemic Response (open access)

Lived Experiences of Families of University Students Amid a Pandemic Response

This study explores students' and their families' experiences during the pandemic response to COVID-19 by the higher education community. Using the hermeneutic phenomenological approach, we employed two open-ended surveys and semi-structured interviews of 16 parent-college student dyads (N = 34). The study draws on students' and parents' retrospective accounts beginning Spring 2020 through the Fall 2020 semesters. Families experienced a disruptive event initialized by the ebb and flow of information. Students' experiences varied based on their expectations and academic classification. The most consistent family challenges were the displacement of students and parents from their physical education and work locations while having to maintain student and occupation responsibilities. The educational experience was inconsistent and dependent on each professors' capacity to engage the students in the online environment. Students expressed feelings of loss of their student and educational experiences, but most students felt the spring courses prepared them to continue their education. Assignments due at random times and poor communication about expectations inhibit students from having dedicated time to interact and make memories. Most families adapted to the new normal by supporting the family members' identities as students and employees and ensuring everyone had the resource needed to succeed. Families experienced monotony …

Measurement Invariance of a Posttraumatic Stress Disorder Symptoms Measure (PCL-5) in College Student and Amazon's Mechanical Turk Samples (open access)

Measurement Invariance of a Posttraumatic Stress Disorder Symptoms Measure (PCL-5) in College Student and Amazon's Mechanical Turk Samples

College student and Amazon's Mechanical TURK (MTURK) samples are regularly utilized in trauma research. Recent literature, however, has criticized these samples for not being generalizable to the general U.S. population. Measurement invariance (MI) using confirmatory factor analyses (CFA), is rarely utilized in trauma research, even though the analysis can determine whether groups are invariant across factor structure, factor loadings, item intercepts, and residual error variances on a given measure of PTSD symptom severity. The purpose of this study was to determine whether college student (n = 255) and MTURK (n = 316) samples are invariant on the PCL-5. Model fit indices indicated the 7-factor Hybrid model was the best fitting model, but the 6-factor anhedonia model was the most parsimonious model. Both models demonstrated equivalence in factor structures (configural invariance), factor loadings (metric invariance), intercepts (scalar invariance), and residuals (strict invariance), indicating MTURK and college student samples are similar in regards to PTSD symptom severity. These findings provide evidence that these groups can be combined in future studies to increase sample size for trauma research. Only the Anhedonia factor exhibited mean differences between groups, which may be related to true differences between college students and MTURK survey-takers. Thus, there is …

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics (open access)

Mixed Development and Validation of an Authentic Assessment for Middle School Mathematics

In response to concerns about using only standardized multiple-choice assessments, some school districts have moved to using alternative ratings of student achievement with authentic assessments. However, such assessments are often limited in terms of the psychometric validity data supporting their use. The present study mixed quantitative and qualitative methods to examine the validity, development, and refinement of an authentic rating approach currently in use in middle school mathematics classes from a large suburban school district in the Southwest United States. A sample of teachers (n = 14), rated students (n = 110) using a pilot rubric of 187 items. Analyses resulted in a 32-item rubric with 20 themes and 9 factors. Results from a G-study revealed the facet that best explained variance in student scores was the interaction between raters and assessment units, as well as students and assessment units. As part of the development of the assessment, a content validity exercise revealed 18% of the rubric items as below average quality. Findings highlight the need to enhance contextualization of rubrics, use a strategy of assessment that includes contextualized and decontextualized assessment, and to investigate the role of utilization deficiency in explaining low student scores.

Mothers' Parenting Stress in Chinese Immigrant Families: The Role of Fathers' Involvement and Social Support (open access)

Mothers' Parenting Stress in Chinese Immigrant Families: The Role of Fathers' Involvement and Social Support

This study investigated the association between Chinese immigrant mothers' reports of parenting stress and two sources of parenting support: fathers' support and social support. Five independent-samples t-tests were first computed to examine whether there were discrepancies between Chinese immigrant mothers' and fathers' perceptions of fathers' involvement across five domains of fathers' involvement in early child care: (1) fathers' warmth and attunement; (2) control and process responsibility; (3) emotional involvement; (4) indirect care; and (5) positive engagement. Then regression analyses were conducted to understand how and to what extent the five domains of father involvement reported by mothers and mothers' perceived social support influenced Chinese immigrant mothers' parenting stress. In addition, an indirect effects of mothers' self-efficacy on the relation between fathers' involvement and mothers' parenting stress was also tested. The results showed that Chinese mothers reported significantly greater level of fathers' emotional involvement than the same type of involvement reported by Chinese immigrant fathers. This study also found that fathers' emotional involvement reported by Chinese immigrant mothers was a significant predictor of Chinese immigrant mothers' parenting stress. However, mothers' perceived social support was a stronger predictor, accounting for more variance in their parenting stress than their reports of fathers' involvement …

Parenting Style, Frequency of Electronic Communication with Parents, and the Development of Independence in First Year, First Semester College Students

During the transition to college, emerging adults are expected to develop independence and increase individual responsibility as they live away from home for the first time. Modern electronic communication has enabled emerging adults to maintain frequent, daily contact with the parent, a pattern of communication Hofer refers to as an “electronic tether.” This study examined the link between parenting style and the development of independence of first year, first semester college students. Although these students were in frequent contact with their designated parent, no correlation between frequency of communication and parenting style or independence was found. Both authoritative and helicopter parenting significantly positively predicted attitudinal independence. However, permissive parenting functioned as a significant negative predictor. Authoritarian, permissive, and helicopter parenting significantly positively predicted conflictual independence. However, authoritative parenting functioned as a significant negative predictor. Both authoritative and helicopter parenting significantly positively predicted emotional and functional independence.

Physical Literacy and Intention to Play Interscholastic Sports in Sixth Grade Physical Education Students

Prevalence of physical inactivity in children and adolescents and the associated epidemic of obesity are increasing concerns. U.S. national health statistics indicate early adolescence (i.e., 10-14 years) appears to be a period of importance regarding physical activity, sedentary behavior, health-related physical fitness, and obesity trends. Considering a significant portion of their waking hours are spent in school, it is widely held that schools' should play a significant role in increasing students' physical activity and health-related physical fitness. To do this, physical education in schools focus on providing quality physical education programs that produce physically literate individuals who have the knowledge, skills, and confidence to enjoy a lifetime of health-producing physical activity. In effect, a call for developing a comprehensive and valid measure of physical literacy has been aptly expressed. Thus, the purpose of this dissertation was to test the psychometric properties of proposed models of physical literacy, examine correlates of the physical literacy factor, and investigate the significance of the relationship between physical literacy and interscholastic sport intention via structural equation modeling. Participants were 400 (231 female, 169 male) sixth-grade physical education students who completed three brief surveys assessing maturation, self-efficacy, self-esteem, knowledge and understanding, motivation, physical activity and sport …

Reaping the Seeds of Leadership: Evaluating a Proposed Model of Lifespan Leadership Development

Though research suggests that several factors are related to the onset of leadership, few researchers have endeavored to determine how these factors may interact to bring about early leadership development. A descriptive discriminant analysis was conducted to test the validity of early factors cited by Murphy and Johnson; namely, lower scores on measures of temperamental negative affect, higher scores of temperamental extraversion, effortful control, orienting sensitivity, authoritative parenting style, secure adult attachment, older relative age, and more reported team sports and extracurricular activities experiences were hypothesized to predict current and past leaders versus never leaders. Additional analyses investigated possible gender differences in how these early factors may predict leader occupancy. The results indicate that early factors are able to predict leadership status for male students, though a majority of the variance in leader status is still left unaccounted. Implications for future leadership development research and training are discussed.

Relationship between Adolescents' Perceptions of Parental Physical Activity and Their Own Well-Being

The purpose of this study was to examine the relationship between adolescents' perceptions of their parents' encouragement to lose weight and physical activity habits (i.e., exercise habits and sedentary behaviors) and their own physical health-related fitness (HRF) and psychological well-being. Results of structural equation modeling revealed both similarities and differences between boys and girls. Specifically, parental sedentary behavior and encouragement to lose weight related to girls HRF. Among boys, only encouragement to lose weight related to HRF. When inspecting the relationship between HRF and psychological well-being, HRF related to body satisfaction, but not depressive symptoms, among both boys and girls. Results of this study highlight the complex influence that parental perceptions have during adolescent development.

Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review (open access)

Reporting the Performance of Confidence Intervals in Statistical Simulation Studies: A Systematic Literature Review

Researchers and publishing guidelines recommend reporting confidence intervals (CIs) not just along with null hypothesis significance testing (NHST), but for many other statistics such as effect sizes and reliability coefficients. Although CI and standard errors (SEs) are closely related, examining standard errors alone in simulation studies is not adequate because we do not always know if a standard error is small enough. Overly small SEs may lead to increased probability of Type-I error and CIs with lower coverage rate than expected. Statistical simulation studies generally examine the magnitude of the empirical standard error, but it is not clear if they examine the properties of confidence intervals. The present study examines confidence interval investigating and reporting practices, particularly with respect to coverage and bias as diagnostics in published statistical simulation studies across eight psychology journals using a systematic literature review. Results from this review will inform editorial policies and hopefully encourage researchers to report CIs.

The Roles of Coaches, Peers, and Parents in High School Athletes' Motivational Processes: A Mixed-Methods Study (open access)

The Roles of Coaches, Peers, and Parents in High School Athletes' Motivational Processes: A Mixed-Methods Study

Grounded in self-determination theory and achievement goal theory, the purpose of this mixed-methods study was to examine the underlying motivational processes from social environments created by coaches, peers, and parents to motivational outcomes in high school athletes, with an emphasis on the relative influence of social agents in basic psychological needs (i.e., autonomy, competence, and relatedness). The quantitative part of this study tested a hierarchical model of high school sport motivation in a final sample of 311 student athletes (204 boys, 107 girls) using structural equation modeling: social factors (coach-, peer-, and parent-created motivational climates) -> psychological mediators (need satisfaction and frustration) -> types of motivation (autonomous motivation, controlled motivation, and amotivation) -> consequences (subjective vitality, athlete burnout, and intention to drop out). Invariance across gender and across team type (varsity vs. non-varsity) was also tested. Adequate model fits were achieved in separate "brighter side" and "darker side" models across the overall sample, gender, and team type. The follow-up qualitative part of this study explored "how" beyond "what" coaches, peers, and parents contribute to the social environments, need frustration, and negative motivational outcomes in sport in a subsample of 37 student athletes (24 boys, 13 girls) who reported high amotivation/burnout …

Rule Utilization and Rule Shift: A Developmental Study (open access)

Rule Utilization and Rule Shift: A Developmental Study

Current rule-utilization research indicated that subjects successively tested multiple conceptual rules, available from natural preexperimental experience, to solve a sorting task. Prior results suggested that older subjects were more efficient in utilizing rules and shifting to unused rules, possibly due to the availability of more conceptual rules at higher age levels. The experimental groups consisted of third, fourth, sixth, ninth graders, and college students. Each of the five groups contained 16 subjects. The rule-utilization procedure was applied to each group. The procedure contained a multitrial, card sorting task. The feedback given at the end of each trial was limited to the correctness of the entire card sort and did not provide information on the correctness of the sorting for any individual card. All subjects in each group were run until they used both bidimensional rules (the conjunctive and the inclusive-disjunctive rule), or until a limit of 30 trials was reached.

Teacher Self-Efficacy for STEM Talent Development

In order to implement more science, technology, engineering, and mathematics (STEM) into K12 classrooms, it is important to find out whether teachers are comfortable with this pedagogy. To determine teachers' current self-efficacy of STEM pedagogy, teachers in a southern state in the United States were asked to enlighten researchers into this phenomenon. Participants were K12 teachers (n = 119) from a public school district undertaking a district-wide STEM initiative. A measure of STEM teacher self-efficacy and a demographic questionnaire were administered online to participants. STEM teacher self-efficacy data were analyzed, along with demographic data, using descriptive discriminant analysis (DDA) and canonical correlation analysis (CCA). Results suggest some demographic variables are more predictive of STEM self-efficacy (gender, grade level taught, feelings of administrative support, and professional development sessions attended) than others (whether or not gifted courses are taught, age, and length of teaching experience. This data should be used by school administrators that seek to begin or improve STEM pedagogy in their schools.

Using a Slopes Difference Test to Probe Longitudinal Multilevel Interactions in an Aptitude-Treatment or Skill-by-Treatment Context: A Simulation

In order to determine which interventions work best for which students, precision education researchers have examined aptitude-treatment interactions (ATI) or skill-by-treatment interactions (STI) by using multiple regression analysis. In recent years, technological innovation and greater accessibility to more advanced statistical techniques have allowed researchers to examine ATI or STI using longitudinal mixed modeling. Probing techniques for interaction effects like slopes difference tests fit well with an ATI or STI framework, but the power of using a slopes difference test in longitudinal mixed models is unknown. The current study used the simulation method to determine which factors influence the power of a slopes difference test in a longitudinal mixed model. Specifically, the study examined design conditions such as number of waves, number of clusters and participants per cluster, effect size, intraclass correlation, variances and covariance of the random effects, and proportion of treatment to non-treatment participants. These were examined in order to help ATI and STI researchers understand whether the slopes difference test in a longitudinal mixed model is sufficiently powered for their sample and study. Effect size, number of waves, number of clusters, and participants per cluster were found to be strong determinants of power and significantly impacted model convergence …
