The Texas Assessment of Academic Skills (TAAS) Test Scores as Predictors of Academic Success of First-Year Clarendon College Students

The problem in this study was to determine the relationship between the scores on the three parts (reading, writing, and mathematics) of the Texas Assessment of Academic Skills Test (TAAS) and the academic success of first-year students at Clarendon College, Clarendon, Texas. High school grade-point average and gender were also included in the study. The purpose of the study was to develop an equation to predict first-year college grade-point average at Clarendon College . The predictor variables were the three parts of the TAAS Test (reading, writing, and mathematics) , high school grade-point average, and gender. The equation was developed through multiple correlation/multiple regression multivariate procedures. All statistical analyses were calculated through sub-programs of the Statistical Package for the Social Sciences (SPSS). The study was limited to using only 1992/1993 Texas high school graduates who had entered Clarendon College in the fall semesters of 1992 and 1993 directly following high school graduation. A search of Clarendon College records produced 115 students from these groups who fully met all standards defined for the study. Two predictor equations were developed. One developed through a simple regression command included all five predictor variables. The second equation was produced through a stepwise procedure. This …

A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families: a Replication (open access)

A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families: a Replication

The purpose of this study was to re-examine the issue of whether adult children of alcoholics experience more depression, anxiety, and lower self-esteem than do children of non-alcoholic families. This study is a replication of the study of David Dodd, entitled A Comparison of Adult Children of Alcoholic Families with Adult Children from Non-Alcoholic Families. 1990. The measures used in this study were as follows: Children of Alcoholics Screening Test, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Coopersmith Adult Self-Esteem Inventory, and a questionnaire developed by this writer designed to obtain family history regarding not only alcoholism, but other issues of family dysfunctionality as well. The subjects for this study were 231 students enrolled in the counselor education program at this university, all aged 19 or older. Of the 230 subjects, 31 were male and 199 were female. Eleven males identified themselves as children of alcoholics, as measured by the Children of Alcoholics Screening Test, and 60 females identified themselves as children of alcoholics. Thus, a total of 71 subjects in this study were identified as children of alcoholics. T-tests were conducted to see whether any differences existed between the male and female groups. No significant differences were …

The Role of the U.S. Mass Media in the Political Socialization of Nigerian Immigrants in the United States (open access)

The Role of the U.S. Mass Media in the Political Socialization of Nigerian Immigrants in the United States

A mail survey of Nigerian immigrants in Dallas, Texas, and Chicago, Illinois, was conducted during October and November 1995. Four hundred and sixty-eight Nigerian immigrant families in the two cities were selected by systematic sampling through the telephone books. Return rate was approximately 40% (187). The variables included in the study were media exposure variables, general demographics, immigration traits, U.S. demographics, Nigerian demographics, and political and cultural traits. New variables which had not been included in previous studies were also tested in this study: television talk shows, talk radio, diffuse support for the U.S. political system, authoritarianism, self-esteem, and political participation. This study employed multiple regression analysis and path analysis of the data. This study found that Nigerian immigrants have high preference for television news as their main source of political information. This finding is in consonance with previous studies. Nigerian immigrants chose ABC news stations as their number one news station for political information. Strong positive associations existed between media exposure and length of stay in the United States and interest in U.S. politics. Talk radio positively associated with interest in U.S. politics and negatively associated with length of stay in the United States. Thus, this finding likely means …

A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction (open access)

A Study of the Relationships among Relational Maintenance Strategy Usage, Communicator Style and Romantic Relational Satisfaction

This thesis examined student-participants' self-reported use of romantic relational maintenance strategies and their partners' reports of relational satisfaction. Additionally, individuals outside the romantic relationship reported on student-participants' general communicator style. The research proposed that general style reports would be predictive of relational maintenance strategy usage and of romantic partners' relational satisfaction. The study found that general style behaviors may not be indicative of relational maintenance strategy usage or romantic partners' relational satisfaction. Tests of sex differences revealed that females' expression of various relational maintenance strategies and style behaviors are associated with male partners' relational satisfaction; however, no results were obtained indicating specific behaviors expressed by males result in female partners' relational satisfaction.

The Impact of Word Processing on the Written Expression of Students with Learning Disabilities in the Area of Written Expression (open access)

The Impact of Word Processing on the Written Expression of Students with Learning Disabilities in the Area of Written Expression

The purpose of this study was to investigate the effect of word processing on the quality of written expression of students with learning disabilities identified in the area of written expression. A examination of existing research revealed that most studies do not focus on word processing independent of writing instruction. Therefore, the consensus among researchers that word processors make a difference is limited by the influence of instruction within the research setting. Therefore, this study sought to determine the impact made solely by word processing by controlling for instruction. The 75 students who participated in the study represented three groups--students with learning disabilities identified in the area of written expression (LD-W), students with learning disabilities identified in an area other than written expression (LD-O), and general education students (NA). Each student completed four writing samples: (a) descriptive - handwritten, (b) informative - handwritten, (c) descriptive - word processed, and (d) informative - word processed. The writing samples were scored according to the TOWL-3 on the three Spontaneous Composite subtests (e.g., Contextual Conventions, Contextual Language, and Story Construction). In addition, Word Perfect 6.1- Grammatik was used to determine the number of syllables, words, and sentences in each writing sample. A multivariate …

The Relationship between School-Based Decision Making and Student Achievement in Elementary Schools in a Large Urban School District (open access)

The Relationship between School-Based Decision Making and Student Achievement in Elementary Schools in a Large Urban School District

The purpose of this study was to explore whether school-based decision making (SBDM) impacts student achievement. Specifically, the study involved determining if the degree of teacher involvement in SBDM across eight decision dimensions differed between schools that demonstrated the most and schools that demonstrated the least district improvement in student achievement. The population consisted of elementary schools in a large urban school district with more than ten years of SBDM implementation. Student achievement scores from 1993 to 1995 were examined for all 68 elementary schools. Based on degree of improvement for fourth grade scores over the three years, 15 schools from the 25% most improved and 15 schools from the 25% least improved were selected for study. Schools from the two extreme-groups sample were matched on five demographic variables. The Teacher Involvement Participation Scale—TIPS-2 (Russell,1992), an instrument for measuring the degree of SBDM in eight different decision dimensions, was given to all certified personnel at each school. A return of 575 surveys represented 63% of the sample schools' staff. Two short questionnaires were administered to principals and SBDM teams to collect descriptive data. Findings, using MANOVA followed by univariate tests, indicated significant differences between groups in six of the eight …

A Comparative Analysis of the Values That Are Predominant in Private Schools, Public Choice Schools, and Public Attendance-Zone Schools in San Antonio, Texas

Public concern with respect to declining traditional values, character, and family structure in the midst of increased crime, violence, and drug use have brought American education into the political arena and under intense scrutiny. The purpose of this study was to investigate whether or not differences exist in the values fostered in private schools, public choice schools and public attendance-zone schools and whether or not there are differences in the values that are identified by students as compared with teachers. The theoretical framework for the study is based upon the beliefs that values form the foundation of human behavior and that schools influence the values of societies in which they exist.

The Effect of Teacher Training on Internet Usage in the Classroom

The purpose of this study is to determine the impact on student use of electronic information systems when teachers have been given instruction on their use. By providing teachers with a solid introduction to the technology, a handy reference book, and an easy-to-use evaluation tool, it is expected that they will incorporate information found on the internet into their lessons at least twice a month. In addition, teachers will allow students to access information on their own, provided computers and Internet access are available, at least once a month.

Effects of Change Facilitator Styles on Elementary Teachers' Concerns about Adoption of Outcome-Based Education

The impact of change facilitator styles (CFS) on elementary teachers' stages of concerns (SoC) about adopting outcome-based education (OBE) in their schools was studied. The group studied was 266 teachers from the Texas Network for Outcome-Based Education. Principal styles are based on the Concerns-Based Adoption Model (CBAM. Styles were determined by the Change Facilitator Style Questionnaire, and teachers' concerns profiles were measured by the Stages of Concern Questionnaire. ANOVA and t tests were conducted to assess the effects of CFS at each of the seven stages of concern. ANOVA assessed teachers' educational level, experience with teaching and OBE, principal gender and type of community related to SoC. Chi-square addressed the relationship among the demographic variables and CFS. With schools as the unit of analysis, significant differences at stages 0,1,2 were found. When teachers were the unit of analysis, significant differences were found at stages 0,1,2, and 3. Concerns of teachers with Initiator style principals were significantly lower at these stages. All teachers demonstrated concerns typical of nonusers, indicating resistance to OBE. Concerns were significantly lower for teachers with master's degree than for bachelor's at stages 0 to 3. Teachers with the least experience with OBE had significantly higher concerns. Chi-square …

Patterns of Vision, Action, and Effects in Professional Development as Experienced in the Texas Centers for Professional Development and Technology

In 1992, the state of Texas awarded a number of inducement grants to collaboratives of universities, schools, and service centers to develop field-based professional development schools (PDSs) and provide preservice and inservice teachers with extensive professional development. This study investigated the design and effects of the professional development models in these Texas Centers for Professional Development and Technology (CPDTs). This study used qualitative data collection and analysis procedures. Raw data were collected in the form of individual interviews, focus group interviews, documentation, and fieldnotes. Forty-six interviews were completed involving a total of 83 respondents representing all partnering entities: university representatives, school representatives, education service center representatives, and policymakers. Documentation included annual and quarterly reports, grant applications, and program approval requests. Fieldnotes included observational data from site visits. Data analysis was an iterative process using a constant comparative analysis of coded categories emerging fromtranscribed data. This comparison examined: the vision of professional development as perceived by the respondents, the enactment of professional development as experienced by the respondents, and the effects that the CPDT initiative had on professional development as perceived by the respondents. This study revealed 18 themes that were common across all eight Texas CPDTs. The themes revealed patterns …

Life Stress, Coping, and Social Support in Adolescents: Cultural and Ethnic Differences (open access)

Life Stress, Coping, and Social Support in Adolescents: Cultural and Ethnic Differences

Although much research has examined the impact of life stress and the subsequent development of health symptoms, most of this research has been done with White middle class adults. Similar to the adult research, life stress research with children and adolescents has focused on White middle class individuals. The present study expands the knowledge about the stress process in ethnic/racial adolescents while controlling for the effects of SES. A sample population consisting of 103 Black students, 129 Hispanic students, and 105 White students was compared with respect to stressful events experienced, coping strategies, and social support. Students from a wide range of socioeconomic backgrounds were included within each ethnic/racial group studied. After experimentally and statistically controlling for the effects of socioeconomic status, significant differences were observed. Black and Hispanic students reported receiving higher levels of Enacted Social Support (actual support) than White students. Contrary to what has been previous suggested, Black and Hispanic students reported having experienced fewer stressful life events than White students. Other ethnic/racial group differences that emerged included differences in ways in which specific patterns of moderator variables served to enhance the relationship between life stress and psychological symptomatology.

Adult Discouragement: Parents of Children with Craniofacial Anomaly (open access)

Adult Discouragement: Parents of Children with Craniofacial Anomaly

The Discouragement Scale for Adults (DSA) was developed to assess for the Adlerian construct of discouragement in adults age 18 years and over. Data were collected from three samples: norm (n=586), presumed discouraged (n=47), and parents of children with craniofacial anomaly (n=105). Five subscales corresponding to life tasks identified in Adlerian literature as work, love, society, self-significance, and spirituality underlie the 60 item DSA. Item selection was based on ratings by five notable Adlerians and item correlations with scale scores. Gender, age, and ethnicity norms were established for the norm, presumed discouraged, and craniofacial samples. Across three samples, no significant ethnic differences were found. Normative findings indicated females are less discouraged than males on the Total DSA, the society and spirituality subscales. Age findings indicated the 18-34 year old sample is more discouraged than other ages on the Total DSA, the work, society, and spirituality subscales. Presumed discouraged findings indicated females are less discouraged than males on the society subscale. Craniofacial findings indicated females are less discouraged on the society subscale, but more discouraged on the self-significance subscale than males. Age findings indicated the 18-34 year old sample is more discouraged than other ages on the self subscale. Research on …

The Influence of Family Functioning on Identity Formation: a Model of Late Adolescent Identity Development

The influence of theoretically prominent family processes on late adolescent college student identity development was the focus of this study. The primary purpose was to test a model of adolescent identity development. This model proposed that family health variables would predict identity development, and that attachment and separation-individuation would each make unique and additive contributions to identity development. The second purpose was to identify instruments which discretely measured the family processes. The third purpose was to better understand family influences by measuring the processes of exploration and commitment. Participants were 150 male and 150 female college students, between the ages of 18 and 23, and from intact families. Questionnaires completed measured family functioning and identity development. Family functioning measures covered three domains (family health, attachment to parents, and separation-individuation) which formed the set of independent variables. The identity measures (ego identity status and identity process) comprised the dependent variables. A hierarchical regression design was employed where family health variables were entered first, followed by attachment variables, then separation-individuation variables. The results indicated mixed support of the model. First, the proposed model was statistically supported for females as all domains predicted identity achievement and diffusion. For males, only family health predicted …

Stigma and Attributions of Blame toward Persons with AIDS (PWAs) (open access)

Stigma and Attributions of Blame toward Persons with AIDS (PWAs)

A sample of 227 undergraduate students was administered pre-intervention paper-and-pencil questionnaires to assess homophobia, fear of AIDS contagion, symbolic representations of AIDS and homosexuality, and specific personality attributes including authoritarianism, religiosity, and conservatism. Participants then read one of eight intervention vignettes about an ill person; these vignettes varied by sexual orientation of the patient, disease (AIDS versus lung cancer), and mode of transmission (in the AIDS conditions). Participants then completed post-intervention measures assessing the degree to which the ill person in the vignette was responsible and to blame for his illness, the level of stigma toward him, and concerns about social interactions with him. Results indicate the following: a) Attributions of personal responsibility are primarily a function of mode of illness transmission; b) fear of AIDS contagion is predictive of stigma and social avoidance of PWAs; and c) AIDS-related stigma and attributions of blame are largely a function of symbolic associations between homosexuality and IV drug abuse (which were previously stigmatized) and AIDS.

The Use of Similarity Indicies to Assess the Spatial Differences of the Phytoplankton Communities in Lake Ray Roberts, Texas

A study of the phytoplankton communities of Lake Ray Roberts was conducted at three sampling sites on two sampling dates during the summer of 1995, assessing both community structure and chlorophyll a concentrations. Eight similarity indices were then used to characterize and compare the communities of these sites. Both community similarity and chlorophyll a concentrations were evaluated using a minimum detectable difference equation to determine the amount of change that must occur in these parameters in order to be deemed statistically significant. The Bray-Curtis Index was shown to be the most adequate index evaluated, and was subsequently used in conjunction with bootstrap analysis to determine the similarity between the three sampling sites.

Criterion Validity of the MMPI-2 in a State Hospital Setting

The current study investigated the criterion validity of the Minnesota Multiphasic Personality Inventory - 2 (MMPI-2) by comparing participants' profiles with other variables, including diagnosis, length of hospitalization, and chronicity. The specific diagnostic groups investigated were depressed (major depressive disorder; dysthymic disorder; and bipolar disorder, depressed), schizophrenic (schizophrenia, schizophreniform disorder, and schizoaffective disorder), and borderline personality disorder (BPD). Statistical analyses included use of univariate analyses of variance (ANOVAs), multivariate analyses of variance (MANOVAs), regression analyses, and measures of sensitivity, specificity, positive predictive power (PPP), and negative predictive power (NPP). MANOVA results indicated significant differences between diagnostic groups on Scales F, 2, 3, 4, 7, ANX. FRS. DEP. BIZ. M f i , LSE, and FAM. There were considerable differences between males and females when separate MANOVAs were performed for gender groups. Cutoff see ires for classification by diagnosis resulted in significant specificity rates and negative predictive power, but sensitivity rates and positive predictive power were not significant.

Teaching the Inductive Bible Study Method of Bible Interpretation to Adults: a Comparison of Three Instructional Approaches

This study compared three groups of adult learners in a church education environment in order to determine the effectiveness of using lecture/demonstration plus cooperative learning elements with or without group processing (LCL) as compared to the use of lecture/demonstration plus individualistic learning elements (LIL) with the Inductive Bible Study Method (IBSM) as the common subject for all groups. While group A experienced highly structured cooperative learning without having group processing, group B experienced highly structured cooperative learning with an emphasis on group processing. Group C served as a control group. This study took place with a total of five class hours. For measuring student cognitive achievement, the subjects were administered a written pretest and posttest in the form of a "use-of-IBSM measure." For measuring students' attitude toward Bible interpretation (as promoted by IBSM), the students responded to an "attitude-toward-Bible-interpretation measure" at pretest and posttest. For measuring students' affective reactions, the students responded to a posttest-only "students'-satisfaction-with-the-learning-experience measure". Students' attitude toward the philosophy behind IBSM was measured by using an "attitude-toward-IBSM" instrument at posttest. In addition, teachers and students were interviewed orally at posttest to ascertain their affective reactions to the instructional approach they experienced.

Personal Construction of the Self in Outpatients with Major Depression (open access)

Personal Construction of the Self in Outpatients with Major Depression

Clinical depression is characterized by alterations in thoughts, judgment, cognition and social behavior. This study focuses on non-optimal views of self and significant others that are proposed to underlie many of these alterations. Perceptions of self and significant others were elicited using the Role Construct Repertory Grid (Kelly, 1955a). Participants included depressed outpatients with high levels of trait anxiety (n = 27), depressed outpatients with lower levels of trait anxiety (n = 29) and a control group of never-depressed volunteers (n = 28). Consistent with prediction, significant group differences were found for negative self perception, discrepancies between actual self and self goals, alienation from significant others, and inconsistencies in self image. Results provided partial support for the self discrepancy theory of emotionality (Higgins, 1987). Among depressed patients, higher levels of anxiety were associated with increased self negativity and greater discrepancies between actual self and self goals. Increased levels of depression were associated with more alienation from significant others and more consistency in self image. Depressed patients' judgments of self and others were altered from optimal ratios, as predicted by the theory of interpersonal judgment (LeFebvre, LeFebvre & Adams-Webber, 1986). Findings have theoretical and clinical importance for the understanding and treatment …

The purpose of the current study was to examine the relationship between parent and child factors for mothers of children diagnosed with cystic fibrosis to predict mother's psychological distress. Mothers were surveyed to identify measurement models in areas of Child and Parental characteristics and a Full Causal Model of Maternal distress. Factors related to Child Characteristics include general parental stressors and cystic fibrosis specific parental stressors. Factors related to Parental Characteristics include the mother's sense of parental competence and self-esteem. Additional factors related to the Full Causal Model include social support, major and minor life events, and demographics. Results were analyzed using LISREL IV structural equation modeling. Measurement model analysis found a good fit for the Child Characteristics model (Chi Square = 6.85, df = 4, JD = .144, Goodness of Fit Indices = .972) and Parental Characteristics model (Chi Square = 5.89, df = 3, p = .117, Goodness of Fit Indices = .971), but not for the full causal model of maternal distress (Chi Square = 114.98, df = 66, E = .000, Goodness of Fit Indices = .853)

Twenty-nine (Group One, June 8,1995) grass carp (Ctenopharyngodon idella) and five (Group Two, April 18, 1996) grass carp were radio-tagged to monitor movement patterns and habitat preferences on North Lake, a 335 hectare multi-use reservoir located in Irving, Texas. Overall fish mean Average Daily Movement (ADM) rates were 49.2 meters/day (during Half One, 6/8/95-11/30/95) and 5.3 meters/day (during Half Two, 12/14/95-6/6/96). Aquatic macrophtye distribution data were obtained. Radio-tagged grass carp were located in Hydrilla verticillata infested areas increasingly throughout the study, however, percent frequency of Hydrilla along 15 transects did not decrease. Radio-transmitters were equipped with temperature-sensors (10-35 Celsius range). Results indicated that radio-tagged grass carp showed no avoidance of areas of North Lake with elevated water temperatures. Radio-tagged grass carp dispersed quickly from stocking point, then moved into littoral areas infested with Hydrilla. After an initial movement period, most fish remained in a localized area.
