Developing A Theoretical Framework For Visualization-Based Pedagogical Content Knowledge (V-Pck) Based On Middle School Teachers’ Views And Uses Of Visualizations As An Instructional Tool, Jacqueline Samuel

Dissertations

Visualizations is a categorical term that is often used to provide visual imagery to the communication of processes, concepts, exemplar phenomena, and general information. Objects such as graphs, tables, diagrams, animations, and pictures fall in this category. Existing literature focuses primarily on the use of visualizations in the science field at the high school level, collegiate levels, and in pre-service teacher education programs. A gap in the literature exists which examines how science teachers at the middle school level perceive and use visualizations as instructional components in the classroom. The purpose of this study was to examine science teachers views …

Faculty Interactions With Black Male Students At Hbcus And Community Colleges As Predictors Of Academic Achievement In Stem, Antoine Gates

Dissertations

A myriad of studies in STEM education aim to identify the underlying reasons behind poor achievement of Black males in higher education. Research studies have indicated that HBCUs make significant advances in various desired outcomes such as graduation rates for Blacks, especially males. However, Black males at community colleges do not always fare similarly to their counterparts at HBCUs. There are limited studies on faculty interactions with Black males in STEM at community colleges. Therefore, the goal of this study was to identify whether significant differences existed in the interactions STEM faculty formed with Black males at community colleges and …

The Importance Of Practice: Learning To Teach Student-Centered Labs With Confidence, Linda Nix

Dissertations

This quantitative research study examined the relationship between science teachers’ science education experiences (high school, undergraduate science courses, teacher education program science methods courses, in-service teaching, and professional development) regarding exposure to student-centered labs and science teacher self-efficacy in teaching student-centered labs. This research study also examined the relationship between science teachers’ opportunity to practice teaching student-centered labs during their science teacher experiences (teacher education program science methods course, in-service teaching, and professional development) and science teaching self-efficacy in teaching student-centered labs as they relate to the social constructivist and experiential learning theories.

A modified version of the Science Teaching …

A Mixed Methods Approach To Study The Effects Of A Naturalist Summer Program On The Perceptions Of African American Children About Nature, Kendrick Buford

Dissertations

African Americans have been reported to have a more negative outlook on nature than people of other races. Much work has been done to explain this phenomenon through the lenses of social and environmental justice. However, most of this information pertains to adults, and little to no exploration has been done to understand how children could be affected. This lack of information creates a novel research topic. This study addressed the problem using a mixed method analysis to better understand both the narrative of the children and any generalizable conclusions to better understand their attitudes in a summer program titled …

Moderating Effect Of Homeschooling On Retention And Academic Achievement Of Stem Majors At A Private, Faith-Based, Liberal Arts College, Aresia Watson

Dissertations

Previous research has indicated that homeschooling is a growing trend within the U.S. Previous research has also indicated that less than one half of students who begin a STEM major at postsecondary institutions will complete their degree. This study sought to look at the possible moderating effect homeschooling has on the academic achievement and retention of STEM majors at a private, faith-based liberal arts college using a modified version of Tinto’s Model of Student Departure.

Independent sample t-tests were used to compare means and intercorrelations of homeschooled students and traditionally schooled students in unmatched and matched samples for several academic …

The Cultural Adaptation Experiences Of Chinese Higher Education Students In The American Deep South: A Comparison Across Disciplines, Xiaonan Song

Dissertations

In the past decade, Chinese international students have been found as one of the largest international student groups at American institutions across the country. However, the American Deep South was not less frequently studied in the past. Due to the distinctiveness of the Deep South, the researcher conducted this qualitative research on Chinese international students studying in this historically and culturally distinctive region. Mississippi was chosen as a representative state of the Deep South in the current study. The researcher collected data from in-depth interviews from three publicly funded institutions in Mississippi. Besides reporting many common issues regarding to cultural …

A Mixed Method Study: Assessing Critical Thinking, Metacognition, And Motivation In A Flipped Classroom Instructional Model, Phyllis Brown

Dissertations

Technology has changed pedagogical methods in higher education. Educators are using technology more and integrating more active learning techniques. One pedagogical method, the flipped classroom, is suitable for integrating technology and active learning techniques. The pedagogical efficacy of the flipped classroom has not been determined despite being a potential solution for technology savvy millennial students. This mixed method study assessed critical thinking, metacognition, and motivation in higher education flipped classrooms in the United States. Human Anatomy and Physiology Society (HAPS) members teaching traditional and flipped format science courses were purposefully selected to participate in the study. A sample of 14 …

Classroom Response Systems: Does Instantaneous Feedback Affect Students' Knowledge And Self-Efficacy In A Secondary Science Course, Shani Bourn

Dissertations

Technological advancements have enabled educators to bring excitement in student success with instantaneous feedback utilizing classroom response systems (CRS). A quantitative, quasi-experimental research design was used in this dissertation research to build a comprehensive understanding of the impact of instantaneous feedback with student knowledge and student self-efficacy. The purpose of this study was to illuminate the benefits of instantaneous feedback and student self-efficacy with incorporation of CRS in a secondary science course. Statistical analyses were conducted with quantitative formative scores, summative test scores, and self-efficacy questionnaire results prior to the incorporation of CRS, and perceived self-efficacy questionnaire results after experience …

An Exploratory Study Of Osmo Tangram And Tangram Manipulative In An Elementary Mathematics Classroom, Stephenie Schroth, Hengtao Tang, Alison Carr-Chellman, Mona Alqahtani

Journal of Educational Technology Development and Exchange (JETDE)

This exploratory study considered the literature on the history of manipulatives, with attention to tangrams, and examined the use of manipulatives in the elementary classroom through the Osmo Tangram. Specifically, manipulatives can be utilized in assisting elementary students to develop mathematical ability and achievement, with an emphasis on spatial sense. This paper describes design features of first generation virtual manipulatives, the amalgam of real and virtual manipulatives (e.g. Osmo Tangram), and results of an exploratory observational study of Osmo Tangram at the elementary level. Findings are discussed tailored to the future design and implementation of integrating tangram into mathematics instruction.
