Authentic Science In Education: Studies In Course-Based Research At The United States Military Academy, Anthony M. Chase

Open Access Dissertations

This dissertation consists of two studies at the United States Military Academy. Both studies involve the use of Course-based Undergraduate Research Experiences (CUREs). These experiences give students the ability to engage in undergraduate research at an early point in their academic career by replacing traditional laboratory activities with semester-long research projects. Both studies show an implementation of this type of instruction from the Center for Authentic Science Practice in Education (CASPiE). Study 1 shows the specific method of implementation at the military academy and explores learning-based outcomes. Primarily the outcome of critical thinking is demonstrated. Critical thinking is a construct …

The Association Between Tolerance For Ambiguity And Fear Of Negative Evaluation: A Study Of Engineering Technology Capstone Courses, Sergey I. Dubikovsky

Open Access Dissertations

For many students in engineering and engineering technology programs in the US, senior capstone design courses require students to form a team, define a problem, and find a feasible technical solution to address this problem. Students must integrate the knowledge and skills acquired during their studies at the college or university level. These truly integrative design activities do not have a single “correct” solution. Instead, there is an array of solutions, many of which could be used to achieve the final result. This ambiguity can cause students to experience anxiety during the projects.

This study examined the main topics: • …

The Educational Journeys Of First-Generation College Women In Stem: A Grounded Theory Study, Susan Geier

Open Access Dissertations

The purpose of this study was to ascertain the various factors that influenced these first-generation college women as they chose a college and selected a STEM major and subsequently persisted to upper level (junior/senior) status. Twenty-five first-generation college women in STEM majors who attended a research-intensive university in the Midwest were interviewed. Approaching this study using constructivist grounded theory provided the opportunity for deeper insights by examining data at a conceptual level while preserving the voices of the women in this study. The women faced numerous challenges on their journeys, yet they persisted. As the women in this study selected …

Learning About Teaching Science: Improving Teachers' Practice Through Collaborative Professional Learning, Sarah E. Cloutier

Electronic Thesis and Dissertation Repository

This single, descriptive qualitative case study provides a snapshot of elementary teachers and their school principal’s multiple and competing views about personal and contextual factors affecting teacher engagement in collaborative professional learning (CPL) related to science education within the school environment. This study was viewed through the lens of Situated Learning Theory primarily by Lave and Wenger (1991) because viewing knowledge as situated has implications for understanding teacher learning and the design of instructional activities.

Data were collected from three female elementary teachers and their school principal in Ontario for a period of six months. The data included: five principal …

Effects Of Two Prereading Activities On Comprehending Science Text: Reading Abridged Text And Learning Vocabulary Words, Audrey J. Fowler

Dissertations, Theses, and Capstone Projects

The present study examined the effects of two prereading activities designed to improve fifth-grade students’ vocabulary learning and comprehension of science textbook content containing those words. Ninety-three fifth grade students participated in this study. The prereading activities consisted of students reading an abridged version of the text or receiving instruction on vocabulary words drawn from the text before reading the full text once. Students receiving these treatments were compared to a control condition in which students reread the full text passage twice but did not receive any prereading treatment. Students were grouped by reading ability levels into above average, average, …

Eighth Grade Mathematics Intervention: Improving Student Self-Esteem And Content Knowledge Of Targeted Mathematic Skills, Stephanie Hart

Dissertations, Masters Theses, Capstones, and Culminating Projects

By eighth grade some students believe they are “not good” and never will be successful at mathematics. Discouraged by poor grades, negative feedback from teachers or demoralized by repeated academic failure, these students disengage from their mathematics classwork. In some cases, mathematics intervention classes are a last chance to get them back on track to qualify for Algebra I in 9^th grade. The purpose of this study is to identify strategies to reengage students by increasing their academic content knowledge in mathematics and boosting their self-esteem and sense of belonging in the school setting. The review of the literature …

Epistemic Beliefs Of Middle And High School Students In A Problem-Based, Scientific Inquiry Unit: An Exploratory, Mixed Methods Study, Jiangyue Gu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Epistemic beliefs are individuals’ beliefs about the nature of knowledge, how knowledge is constructed, and how knowledge can be justified. This study employed a mixed-methods approach to examine: (a) middle and high school students’ self-reported epistemic beliefs (quantitative) and epistemic beliefs revealed from practice (qualitative) during a problem-based, scientific inquiry unit, (b) How do middle and high school students’ epistemic beliefs contribute to the construction of students’ problem solving processes, and (c) how and why do students’ epistemic beliefs change by engaging in PBL.

Twenty-one middle and high school students participated in a summer science class to investigate local water …

Structural-Symbolic Translation Fluency: Reliability, Validity, And Usability, Matt C. Hoskins

Electronic Theses and Dissertations

Standardized formative mathematics assessments typically fail to capture the depth of current standards and curricula. Consequently, these assessments demonstrate limited utility for informing the instructional implementation choices of teachers. This problem is particularly salient as it relates to the mathematical problem solving process. The purpose of this study was to develop and evaluate the psychometric characteristics of Structural-Symbolic Translation Fluency, a curriculum-based measure (CBM) of mathematical problem solving. The development of the assessment was based on previous research describing the cognitive process of translation (Mayer, 2002) as well as mathematical concept development at the quantitative, structural, and symbolic levels (Dehaene, …

Factors Influencing Math And Science Teacher Intentions To Leave Or Stay In The Teaching Profession, Scott Douglass

Graduate Dissertations and Theses

The purpose of this study was to identify factors that have the greatest influence on math and science teacher intentions to stay in or leave the teaching profession. The independent variables included in this study were: perceived administrative support, influence over classroom and school policies and procedures, salary satisfaction, and stress associated with teaching. A survey was sent to math and science teachers in central Virginia containing questions largely derived from the School and Staffing Survey. Stress associated with teaching and job satisfaction were significant predictors of intent to stay in teaching for teachers. Based on the results of this …

Aspects Of Science Engagement, Student Background, And School Characteristics: Impact On Science Achievement Of U.S. Students, Larry J. Grabau

Theses and Dissertations--Educational, School, and Counseling Psychology

Science achievement of U.S. students has lagged significantly behind other nations; educational reformers have suggested science engagement may enhance this critical measure. The 2006 Program for International Student Assessment (PISA) was science-focused and measured science achievement along with nine aspects of science engagement: science self-efficacy, science self-concept, enjoyment of science, general interest in learning science, instrumental motivation for science, future-oriented science motivation, general value of science, personal value of science, and science-related activities.

I used multilevel modeling techniques to address both aspects of science engagement and science achievement as outcome variables in the context of student background and school characteristics. …

An Investigation Into The Accessibility Of Ap Calculus, Brian Austin Dodge

Capstones, Research Projects, and Curricula

This is a mixed methods ethnographic study conducted to determine what obstacles students face when approaching AP Calculus. I focused my study on home economics, peer pressure, ELL status and home support. Overall, I found that being a student who is ELL (hereafter defined as a student who was or currently is required to take ACCESS testing) had the most negative effect of the previously listed factors. Home economics and peer pressure were inconclusive or often had no effect. Finally, having a supportive home life in the form of parents who value education, encourage goal-setting, and set high expectations had …
