An Evaluation Of The Equitable Practices For Stem Education To Prepare All Students For The 21st Century, Elizabeth Simpson

Dissertations

We are almost a quarter of the way through the 21st Century, yet most education institutions do not provide STEM education for all students. Science, technology, engineering, and math (STEM) have been a special focus of both industry and federal education initiatives in recent years. STEM is a proven way of building student skills needed for the workforce of tomorrow. The purpose of this study is to determine why education decision-makers resist implementing STEM programs equitably for all students. The context of this inquiry is district and school-based leaders throughout the United States, from elementary to high school, who have …

A Quantitative Assessment Of The Effectiveness Of A Global Online Professional Development Course To Enhance 21st Century Skills In Stem Instructional Design, Chris Link

Dissertations

Science, technology, engineering and mathematics (STEM) disciplines are becoming increasingly important in the 21st century workforce, but there is currently a shortage of STEM professionals around the world. Even when students graduate with STEM degrees, many lack basic interpersonal skills such as communication and problem solving that would position them for success in the marketplace. The New York Academy of Science developed the STEM Education Framework to help ensure that STEM curricula teach the Essential Skills that students need in order to thrive in the modern workplace. In order for educators to proficiently utilize the STEM Education Framework, they must …

The Construction Of Student Mathematical Identity And Its Relationship To Academic Achievement, Ann Trescott

Dissertations

The California university and state college systems (UC and CSU) are committed to accepting a diverse student body. Although there has been some growth in the percentage of minority students admitted each year, a low number of minority and socioeconomically disadvantaged students meet minimum entrance requirements. For example, in 2018, only 33% of socioeconomically disadvantaged African American students and 39% Hispanic/Latinx students who graduated from California public high schools met minimum UC/CSU requirements (CDE, 2019).

Explanations for ineligibility include the fact that many high school students have not completed the requisite mathematics classes due in part to the inequitable practice …

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 …

Teachers’ Perceptions Of Educational Games That Keep Score Of Cooperative Performances, Theodore Alden Wohlfarth

Dissertations

The scoring systems used in traditional sports and games are founded on the zero-sum premise that players are on opposite sides and one side can win only if the other side loses. These scoring systems may be effective at nurturing zero-sum mindsets and providing data for assessing performance in win-lose relationships. If so, games that use different scoring systems can be used to facilitate the development of collaborative mindsets, nurture win-win skills between diverse groups, and enable objective self-assessment of performances in non-zero-sum events when engaging with those on “other sides.” Although economic game theory has rich reservoirs of research …

Analysis Of A Stem Education Professional Development Conference For Pre-Service Educators, Keeta Holmes, Pamela Atkinson-Hamilton, Tiffanni Durham, Gloria Hardrict-Ewing, Deborah Heisler, Christina Hughes, Rosalinda Williams, Lane Walker, Christopher Young-El, Amy Dooley

Dissertations

Science, technology, engineering, and mathematics (STEM) disciplines are attracting increased attention in education. The iSTEM 2017 conference was a professional development program designed to acquaint pre-service teachers with interdisciplinary, research-based STEM instructional strategies that can transform traditional classroom instruction into dynamic learning environments.

The STEM Education Scholars (STEMES) is a Learning Community of Practice, housed in the College of Education, at a midsized mid-western public research university. The program of study focused on designing a professional development program for future Pre-K12 teachers. The iSTEM 2017 conference presented by the STEMES Community of Practice sought to inform pre-service teachers of STEM …

A Statistically Significant Determination From Pretest To Posttest In Knowledge Of Electrophoresis Concepts, Parker Megehee Nelson

Dissertations

The statistical significance from pretest to posttest of 109 high students constructing an electrophoresis chamber or not was explored. The students tested were from six intact biology classrooms. Three classes were treatment groups and three were control groups. The three biology teachers each taught a control and treatment group classroom. Except for building the electrophoresis chamber, students in both groups received identical instruction and testing. Pre- and posttest data was examined by means of a content valid test constructed by the researcher and biology teachers. In order to examine the statistical significance from pretest to posttest in knowledge of electrophoresis …

A Method For Assessing And Describing The Informal Inferential Reasoning Of Middle School Students, Joshua Michael Goss

Dissertations

Informal Inferential Reasoning (IIR) has emerged in the last decade in the study of statistics education. Developing students’ IIR ability is seen as a way of preparing students for the important topic of Formal Statistical Inference (FSI); however, research is still needed in order to investigate how students transition between informal and formal statistical reasoning. A primary difficulty is that we do not have a way of assessing and describing students’ IIR ability levels. In order to address this, an Assessment of Informal Inferential Reasoning (AIIR) was developed, along with a Structure of Observed Learning Outcomes (SOLO) taxonomy (Biggs & …
