Impact of Teacher and Student Ethnicity on Student Assessments

The purpose of the study was to answer the questions: Do students show greater academic success in English language arts/reading as measured by the Texas Assessment of Knowledge and Skills (TAKS) exam scores in secondary education when their teachers are the same ethinicity? Do students show greater academic success in math as measured by the TAKS exam scores in secondary education when their teachers are the same ethnicity? Minority students' success on the TAKS test was compared to the assessment scores of White students from the 2010-2011, 2011-2012, and 2012-13 school year in thre suburban school districts. This topic has been a subject of discussion since the late 10970s when Cardenas and Cardenas (1977) studied the achievement among minority students and their White peers. The conversation continued through authors such as Takei and Shouse (2008), Hays (2011), Ladson-Billings (2006), Dee (2003, 2005), and Brown (2006). To answer these research questions, a hierarchical multiple regression analysis was conducted on the data collected. Although the study verified the achievement gap between minority students and White students, the study indicated no consistent pattern corroborating that minority students were more successful when taught by teachers of the same ethnicity. In many cases, students learned …

An Investigation of Preservice Teachers' Understanding of Buoyancy (open access)

An Investigation of Preservice Teachers' Understanding of Buoyancy

The purpose of this study was to examine the conceptual understandings of 55 elementary preservice teachers for the concept of buoyancy. This study used Ausubel’s Assimilation Theory (Ausubel, 1963) as a framework for a 15-week intervention that used pre/post concept maps (Cmaps), pre/post face-to-face semi-structured interviews, and drawings as evidences for change of formation of cognitive structures. Using a convergent parallel design and mixed methods approach, preservice teachers’ conceptions were analyzed using these evidences. Results of the study show that preservice teachers held both scientific conceptions and misconceptions about buoyancy as a force before and after an instructional intervention. Of importance were the existence of robust misconceptions about buoyancy that included inaccurate scientific knowledge about the foundational concepts of gravity, weight, mass, and density. The largest gains in scientific knowledge included the concepts of gravity, surface area, opposing forces, and the buoyant force. These concepts were consistently supported with evidence from post-concept maps, post, semi-structured interviews, and drawings. However, high frequencies of misconceptions were associated with these same aforementioned concepts as well as additional misconceptions about buoyancy-related concepts (i.e., weight, density, displacement, and sinking/floating). A paired t test showed a statistically significant difference (t = -3.504, p = .001) in …

Do Re Mi? Yes! Using Music and Visual Arts to Promote Thai Children's English Vocabulary Development

This research examines the efficacy, if any, of the Music and Visual Arts (MVA) program in improving the English vocabulary development of first grade Thai students. The researcher developed the Vocabulary Recognition Assessment (VRA) as a measure of English vocabulary development. It employs the accuracy and rapidity method of word recognition as a measurement of English language development in Thai children. Forty first grade Thai students in a Bangkok elementary school participated in the study. Participants were divided equally between an experimental group and a control group. During a nine-week period, students in the experimental group were instructed with the MVA strategy, while students in the control group were taught with the Visual Arts (VA) strategy. Paired sample t-test, ANOVA, and ANCOVA were used to analyze data from the VRA, to compare the pre-test and the post-test in terms of accuracy scores and rapidity scores of the control group and the experimental group. Data revealed that students instructed with the MVA strategy improved their English vocabulary development in terms of accuracy of word recognition significantly more than students taught English using the VA strategy. No significant difference was found between the MVA strategy and the VA strategy in terms of …
