The Impact Of Project-Based Learning On Students In High School Chemistry In Rural Maine, Brianna Degone

Electronic Theses and Dissertations

Project-based learning (PBL) is an instructional strategy that is promoted throughout education for its use of active learning and ability to connect to real-world applications. Studies have been conducted on PBL ranging from early elementary grades through graduate courses, however little research considers the effectiveness of PBL at the secondary science level. This thesis considers the use of PBL and describes the implementation of a PBL unit in a rural Maine 11th grade chemistry classroom. The thesis aims to better understand the impact PBL has on students’ content learning and additional skills acquired through the PBL learning process. Along with …

A Causal Comparative Study Of Stem Persistence Between Supported And Non-Supported Stem Interested Students, Elizabeth Bernardi

Electronic Theses and Dissertations

Many students who enter a STEM track in college move out of that track before graduation (National Science Foundation, 2018). The purpose of this study was to assess whether there was a difference in STEM-related major persistence for population proportions of students actively involved in the Science Scholars program and those who were STEM-interested but not program participants. This program oriented students to the STEM program, facilitated engagement with peers and faculty, exposed students to research opportunities, and filled in potential learning gaps (Gibson et al., 2019).

The questions guiding the current research included:

Q1. Was there a statistically significant …

Chinese Female Students And The Stem Gender Gap: How Stereotype Threat And Expectancy Value Shape Performance And Engagement, Yixin Qiao

Electronic Theses and Dissertations

Globally, women have been underrepresented in science, technology, engineering, and mathematics (STEM) fields, and this is true in China. The current study seeks to identify factors that shape adolescent girls’ decision-making when deciding whether to pursue STEM studies and the barriers they face. The study likewise seeks to develop recommendations to encourage and empower girls to choose STEM. Data was collected from one-on-one interviews with six Chinese female international students: three in the STEM fields, and three in non-STEM fields at a comprehensive university in southwestern Ontario. The interviews explored the familial, educator, and peer influences that promoted or challenged …

An Investigation Of Students' Use And Understanding Of Evaluation Strategies, Abolaji R. Akinyemi

Electronic Theses and Dissertations

One expected outcome of physics instruction is that students develop quantitative reasoning skills, including evaluation of problem solutions. To investigate students’ use of evaluation strategies, we developed and administered tasks prompting students to check the validity of a given expression. We collected written (N>673) and interview (N=31) data at the introductory, sophomore, and junior levels. Tasks were administered in three different physics contexts: the velocity of a block at the bottom of an incline with friction, the electric field due to three point charges of equal magnitude, and the final velocities of two masses in an elastic collision. Responses …

Investigating The Attitudes, Beliefs And Practices Of High School Chemistry Teachers Regarding The Differentiation Of Instruction, Anna Tyrina

Electronic Theses and Dissertations

Differentiation of instruction (DI) is a broad term used for a group of pedagogical tools that teachers use to individualize instruction for students of different abilities and needs. Differentiation of instruction is a practice that has been researched and characterized to have a variety of instructional benefits, some of which include increased student motivation and engagement (Tomlinson, 2001). This study sought to characterize the attitudes, beliefs, and practices of ten high school chemistry teachers in Maine regarding the differentiation of instruction. Through a phenomenological approach, interviews with these teachers were analyzed to understand how high school chemistry teachers define differentiated …

Engineering Performance And Teamwork Perceptions Shaped By Structured Learning Experiences In A Makerspace., Teresa Lee Tinnell

Electronic Theses and Dissertations

The ability to work on teams is of critical importance to the field of engineering and a critical competency for future engineers. Fostering performance of effective teamwork through the education of engineers emphasizes the humanistic dimension of the engineering profession and engages future engineering professionals in complex and dynamic team experiences. Team performance and effectiveness of student teams is strongly influenced by individual student perceptions of teamwork as a learning mechanism for successful collective learning experiences. Initial perceptions of teamwork among first year engineering students are often negative due to prior adverse or unproductive team performance. Makerspace learning environments are …

A Case Study Into Middle School Students' Conceptualizations Of Motion And Interpretations Of Negative Velocities, Peter A. Colesworthy

Electronic Theses and Dissertations

Student difficulties surrounding motion have been well documented for many years. This work was inspired by the work of former MST students into the instruction of Newton‟s Second Law of Motion at the middle school level. The purpose of this study was to further investigate how middle school students talk and reason about motion. Particular attention was paid to how students defined the term “motion,” how those definitions fit into a larger framework of what encompasses understanding motion at the middle school level, and how students justified negativity of a calculation of a negative velocity.

A tutorial lesson was developed …

Assessing The Effectiveness Of A Tool For Classifying And Assessing Student Energy Diagrams In Pre- And Post-Covid-19 Instruction, Michael Dudley

Electronic Theses and Dissertations

Energy is a broad concept that is used to interpret and understand scientific phenomena, and appears throughout the Next Generation Science Standards (NGSS) at all grade levels and across disciplines. The NGSS specifies no single approach for energy instruction, and makes use of different energy metaphors, often within individual standards. Gray, et al. (2019) created a checklist (the “Gray Checklist”) to identify whether or not a diagram exhibits evidence of core constituent ideas that align to the energy model of the NGSS. This study used the Gray Checklist to find trends in student energy diagrams that were produced during a …

The Peacock In The Room: Confronting The Hidden Curriculum Of Androcentrism And Gender Bias In Undergraduate Biology Education., Sarah Hamilton Spaulding

Electronic Theses and Dissertations

This dissertation exposes one manifestation of the hidden curriculum of gender bias in the biological academe and explores the impacts of implicit essentialist perspectives on biology curricula and student understanding of an important evolutionary concept. Chapter one introduces the concept of gender essentialism and its relationship to the hidden curriculum of gender bias. I conclude the introductory chapter by reviewing tenets from queer curriculum theory and suggesting that applications of the theory may provide educators with the pedagogical tools required to counter implicit essentialist perspectives. Chapter two describes a textbook image analysis informed by previous textbook analyses to examine the …
