This qualitative case study examines interviews and classroom observations of undergraduate chemistry students enrolled at a primarily undergraduate institution. Critical educational elements were identified for chemistry students participating in a redesigned, introductory course which included a collaborative peer-lead learning experience. The participants engaged in required, weekly sessions structured around community building and active learning. The data were …

A Study Of Underrepresented Minorities In An Informal Stem Experience, Rachel Rogers

Theses and Dissertations--Education Sciences

According to labor market data, there is core cognitive knowledge, skills, and abilities associated with STEM education that are in demand in not just STEM fields, but all areas of the workforce (Carnevale, Smith, & Melton, 2011; Rothwell, 2013). During the period from 2005 until 2015, STEM professions grew by 24.4% (Noonan, 2017). During this time, populations such as minorities continued to show a gap in their representation in STEM (Noonan, 2017). To effectively examine how to increase the rate of URM student success in STEM, more research is needed on the factors that might contribute to minority STEM interest, …

Co-Teaching In High School, Ashley Evans

Student Research Poster Presentations 2022

Students with and without disabilities are entitled to a free and appropriate public education. All students should be given the best education no matter the circumstances that may be present. Implementing the co-teaching model and framework into high school general education classrooms can benefit all students. Where there are benefits with teaching models, there are also drawbacks that can cause the implementation of the model not to be implemented as created. Difference causes can cause this that school districts may or may not be able to control. The lack of professional development, certifications of the educators, and defining the roles …

Why Do I Teach Math This Way: A Qualitative Examination Of How Teacher Experiences Impact The Implementation Of Instructional Practices, Carrie A. Heaney

Master's Theses and Doctoral Dissertations

Since the 1960s, there has been an effort among the mathematical education community to shift instructional practices from a focus on arithmetic, memorizing rules, and completing practice worksheets to instructional practices that allow students to see mathematics as content that requires thinking and pattern explorations. Many mathematics teachers have not fully embraced these shifts in instructional practice. This study aimed to examine secondary mathematics teachers’ experiences and how those experiences connect to teachers’ implementation of student-centered instructional practices in the lessons they design. This qualitative study utilized a grounded theory approach to examine how a teacher’s experiences as a student …

Gender Differences In High School Students’ Perceptions Of Math And Science Identity, Self-Efficacy, And Utility, Lauren Mauel

All Electronic Theses and Dissertations

This quantitative dissertation examined the differences between young men and women’s perceptions of mathematics and science identity, self-efficacy, and utility. There are gender norms and stereotypes that impact identity, self-efficacy, and perceived utility of mathematics and science. The secondary data analyzed were drawn from the follow-up High School Longitudinal Survey (HSLS:09). The survey was administered to 20,594 11th-grade students enrolled at 904 eligible public, charter, and private schools from all states and the District of Columbia. The study investigated whether there are gender-based statistically significant (p < 0.05) differences in 11th grade students’ perceptions of mathematics and science identity, mathematics and science self-efficacy, and mathematics and science utility. The results of the study suggest that there are statistically significant differences between the genders in mathematics identity, science identity, mathematics self-efficacy, and science self-efficacy, but not statistically significant differences in mathematics utility and science utility. Continued research could prove useful to continue analyzing the gender gaps present.

Feedback is an essential form of communication between the student and teacher. Research has documented the importance of feedback in advancing student mathematical and critical thinking, with renewed recommendations to provide and use feedback in mathematical instruction during the era of COVID-19. Giving personalized feedback in an online environment can be a challenge – especially in a mathematics class. This article summarizes five core principles of feedback, associated strategies for mathematics teachers to provide students virtual feedback, and notes on how we have implemented these strategies in middle school mathematics classes.

An Exploration Of The Use Of Science Specialists And Elementary Students’ Science Achievement, Wesley Roach, Jillian L. Wendt

Journal of Mathematics and Science: Collaborative Explorations

The purpose of this causal-comparative study was to examine the effect of using science specialists in elementary schools on science achievement scores. The sample population consisted of 282 fifth grade students enrolled in Georgia public schools. The data for this study was collected from four public elementary schools’ end-of-year state assessments and analyzed as archival data. An analysis of covariance (ANCOVA) was used to determine if there was a difference between science achievement scores in elementary schools that use science specialists compared to those that do not. Results indicate that no statistically significant difference exists between the science achievement scores …

High School Students’ Nature Of Science Understandings And Scientific Argumentation Skills In The Context Of Socioscientific Issues, John Michael Williams

Dissertations and Theses

Today’s high school graduates are required to digest and interpret massive amounts of information related to science. National standards documents in science education promote the development of skills to effectively evaluate the credibility of scientific information, with the goal of producing citizens capable of making scientifically informed decisions after graduation. These skills include the ability to make reasoned arguments based on evidence (Scientific Argumentation [SA]) and an understanding of how scientific knowledge is generated, validated, and communicated (Nature of Science [NOS]). While the importance of these skills is not in dispute, the few studies that have examined the connection between …

The 6e Instructional Model In The Mathematics Classroom, Danielle K. Deutsch

Honors Projects

The focus of this action research study is to compare the 6E instructional model to a traditional instructional model in the mathematics classroom. Literature shows that the 5E model has a significant positive impact on subject mastery, knowledge permanence, and students’ attitude and interest toward the content. Further, the 6E model is shown to allow for easy implementation of tiered differentiation strategies so that all students’ needs are met. Two classes of seventh grade students received instruction on the same content, with one class receiving 6E instruction and the other receiving traditional, lecture-demonstration style instruction. Results showed that the 6E …

A modified Draw-A-Science-Teacher-Test was used to examine teachers’ perceived instruction during the Fall of 2019, Fall of 2020, and Fall of 2021. Scores on this modified checklist were compared to determine differences in instruction year-to-year, across grade-bands, and to find trends in instruction concerning student demographics. Interviews were conducted with a subset of teachers in the study to learn more about the dilemmas they faced as their attempted science …

Equity Through Growth Mindset, Raven Robinson-Wilson

STEM Integration

This activity occurred during a live, class session that included a focus on equity by addressing, “What qualities and mindsets can we foster in STEM students?” First, we reviewed Growth Mindset Theory, but re-imaged with an explicit focus on equity, with connections to STEM. Then, the teachers were presented with several growth mindset scenarios. The teachers worked in groups by reading the scenarios, elaborated on the context where they might encounter the situation, then improvised how they might respond. They wrote out plans for what they would do.

Using Formative Assessment To Build Coherence Between Educational Policy And Classroom Practice: A Case Study Using Inquiry In Science, Connie Cirkony, John Daniel Kenny

Australian Journal of Teacher Education

In this paper we argue that the complexity of education systems can lead to a lack of coherence in the implementation of policy. More effective educational change requires policy-makers and researchers to pay more attention to supporting teachers in classrooms. As an example, we consider decades of research attempts in STEM education to implement learning through inquiry and note there has been little change in teaching practices in classrooms. Using formative assessment in science education as a case study, we developed a rubric for teachers that embeds key aspects of the desired pedagogy. We argue this builds teachers’ confidence to …

Teacher Self-Efficacy And Mathematics Achievement Among Racial And Ethnic Minority Students: Evidence From The High School Longitudinal Study Of 2009, Eliud Partida

CGU Theses & Dissertations

Current data suggests that for every 1000 U.S. high school students only about a dozen from Racial and Ethnic Minority (REM) groups will obtain a STEM degree and pursue a STEM occupation. These numbers underscore the wealth of untapped talent in our high schools and the pressing need to broaden participation among REM students in STEM. Yet, policies aimed at improving teacher quality as a vehicle for broadening participation of REM students in STEM use measures that at best, are only weakly associated with positive educational outcomes for REM students. This study contributes an ecological perspective and analysis to advance …

The Impact Of Socioeconomic Status On The Development Of Stem Identity, Choice, And Persistence, Shawna Adams

Murray State Theses and Dissertations

Abstract

This mixed-methods study seeks to investigate the direct effect that socioeconomic status (SES) has on a student's identity, choice, and persistence in science, technology, engineering, and math (STEM). There is a diversity and wage gap among the STEM workforce, which is comprised largely of White males with higher salaries than their counterparts. Underrepresented minority groups (URMs) are more likely to come from low SES and typically have fewer educational resources. Identifying the relationship of SES across student groups can yield insights about how to address inequitable practices and increase STEM diversity. Quantitative data was collected via a STEM survey, …

Students’ Perceptions Of Specific Laboratory Curricula On The Learning Experience In Chemistry Courses, Arwa Ali Alshehri

Electronic Theses and Dissertations

Laboratory courses play a key role in developing critical thinking and problem-solving skills and providing experience in certain aspects of a laboratory setting including reactions, materials, and equipment. Prior studies suggest that a laboratory course assists students toward cognitive gain on lecture content. In contrast, other studies conclude that laboratory is uncorrelated with cognitive gain on lecture content. Thus, a discord exists between researchers regarding the role that laboratory experiences play in furthering the understanding of chemistry concepts taught in lectures. The purpose of this research is to examine the impact of two different laboratory curricula on students’ performance in …
