The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao Aug 2014

The Relationship Between Teaching Approaches And Student Science Achievement For Four Racial Groups In Us Eighth Grade Classes, Su Gao

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lower science achievement and substantial racial performance gaps persist among students in the US. In the current reform of science teaching, inquiry-based science teaching is assumed effective in improving all student science learning in both scientific content and process and reducing learning gaps across racial groups. Conversely, traditional didactic science teaching is believed to be the most popular and has contributed to lower science achievement and the racial gap. These two assumptions, although central to science teaching reforms, cannot be empirically sustained in the existing literature on science teaching. Framed through the theoretical perspectives of inquiry-based instruction and culturally relevant ...


The Impact Of School-Level Factors On Minority Students' Performance In Ap Calculus, Phillip Bruce Pearson Jun 2014

The Impact Of School-Level Factors On Minority Students' Performance In Ap Calculus, Phillip Bruce Pearson

Dissertations and Theses

In recent years, Science, Technology, Engineering, and Technology (STEM) talent pool has re-emerged as a national priority. Certain racial and ethnic groups are dramatically underrepresented in STEM careers and STEM educational programs, an especially serious concern given demographic transitions underway in the United States. The College Board's Advanced Placement (AP) Calculus program provides one way in which students can gain exposure to college-level mathematics while still in high school. This study analyzed factors that contribute to the success of minority students in AP Calculus using a large, longitudinal (2007-2012), geographically distributed dataset which included important school-level variables and AP ...


Associations Between Input And Outcome Variables In An Online High School Bioinformatics Instructional Program, Douglas S. Lownsbery Apr 2014

Associations Between Input And Outcome Variables In An Online High School Bioinformatics Instructional Program, Douglas S. Lownsbery

Dissertations and Theses

Quantitative data from a completed year of an innovative online high school bioinformatics instructional program were analyzed as part of a descriptive research study. The online instructional program provided the opportunity for high school students to develop content understandings of molecular genetics and to use sophisticated bioinformatics tools and methodologies to conduct authentic research. Quantitative data were analyzed to identify potential associations between independent program variables including implementation setting, gender, and student educational backgrounds and dependent variables indicating success in the program including completion rates for analyzing DNA clones and performance gains from pre-to-post assessments of bioinformatics knowledge. Study results ...


Thinking Like A Scientist: A Thematic Analysis Of Students' Experiences At The Sacnas Research Conference, Rosa Perez, Rachael D. Robnett Jan 2014

Thinking Like A Scientist: A Thematic Analysis Of Students' Experiences At The Sacnas Research Conference, Rosa Perez, Rachael D. Robnett

McNair Poster Presentations

The underrepresentation of minority students in STEM fields is a concern in today’s society. Research suggests that identity plays a major role in students’ ultimate success within these fields. Using identity theory as a theoretical framework, this study explores the ways in which identity affects the academic careers of underrepresented students in STEM. The participants of this study consisted of undergraduates from various colleges and universities around the United States that attended the SACNAS 2010 research conference. Thematic analysis was used to identify four overarching themes from a set of narrative responses collected after the event. The identified themes ...
