The purpose of this study was to investigate the impact of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science. Master's degree students enrolled in the elementary Fairfax Partnership Schools (FPS, n = 21) cohort served as the…

The problem addressed in this study was that there is a lower amount of young underrepresented minorities (URMs)--African American/Black and Latino/Hispanic students--proficient in science, technology, engineering and mathematics (STEM) who are prepared to enter STEM professions compared to their Asian and Caucasian/White (non-URMs) peers;…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

The purpose of this study was to investigate whether participation in a school-based science fair affects middle school students' attitudes toward science and interest in science and engineering careers. A quasi-experimental design was used to compare students' pre- and posttest attitudes toward and interest in science. Forty-eight of…

Student enrollment in undergraduate online education continues in an increasing trend toward the creation of new virtual degree programs. Academia and university faculty have observed comparable learning outcomes in both traditional and online classrooms, but minimal research exists discussing student perspectives of science-based coursework in…

This study examines how Science, Technology, Engineering, and Mathematics (STEM) Education may improve English Language Learners' academic achievement and high school graduation. In particular, it highlights the plight faced by ELLs in high schools regarding quality education that allows them to graduate on time and attend college. The analysis…

The purpose of this study was to investigate elementary teacher perceptions of elementary principal instructional leadership and elementary teacher evaluation of self-efficacy at low and high performing low socio-economic elementary schools. These variables were examined to determine whether relationships with math and science academic achievement…

Middle school is a critical period in the cognitive and academic development of young women, and a time when their performance and interest in science may decline. After school programs play a key role in engaging youth in learning by providing opportunities to increase health and wellness, set goals, and strategize problem solving. Skills…

The National Science Foundation (NSF)-funded Urban College (UC) Scholarships in Science, Technology, Engineering, and Mathematics (S-STEM) program was designed to comprehensively support academically talented low-income students. The program served 45 students between the fall semesters of 2012 and 2015. The primary goals of the program were…

This research focuses on a cohort of pre-service elementary teachers and their perspectives with respect to the knowledge required for teaching science and mathematics at the beginning and end of their first academic year in a teacher preparation program. An activity, designed to emphasize the differences between factual/procedural knowledge and…

The purpose of this study was to ascertain whether certain contextual factors pertaining to principals and teachers influenced U.S. eighth grade students' math achievement. More specifically, the study comparatively examined the direct and mediating predictive influence of teacher instructional approaches (i.e., teacher-directed; constructivism),…

Purpose: The purpose of this study was to use Dr. James Stronge's taxonomy of the qualities of effective teachers to determine whether there are significant differences in the instructional efficacy between first- and second-career teachers who teach math and science. Methodology: A causal-comparative study examined the effects of variables that…

Reform movements in science education have repeatedly called for more dialogic and student-centered discussions during science lessons. The approach secondary science teachers take towards talk during whole-class discussions continues to be predominantly teacher-centered even when curriculum materials are designed to support a shift in discourse.…

It has been documented that American Indians and girls consistently underperform in STEM achievement compared to their European American and male counterparts, starting as early as adolescence. The goal of the current study was to develop a brief intervention aimed at mitigating the STEM achievement gap by shaping ethnic and gender identities to…

The purpose of the quantitative research study was to determine if participation in the Health Sciences and Technology Academy (HSTA) led to significant differences in the math and reading/language arts scores on the West Virginia Educational Standards Test 2 (WESTEST 2), between students who participated in the program compared to students who…
