Determining The Difficulty And Discrimination Parameters Of A Mathematics Performance-Based Assessment, Abraham Gyamfi, Douglas G. Wren

Educational Leadership & Workforce Development Faculty Publications

Performance-based assessment (PBA) is different from traditional testing methods in that PBA presents real-life problems for students to solve by integrating critical thinking with their content knowledge and skills. Implementing PBA regularly in mathematics classes is associated with improved student achievement and motivation to learn; however, there are concerns about the general lack of psychometric data to support the use of performance assessments. To address such concerns, this study applied item response theory to estimate the difficulty and discrimination indices of items that comprised a newly developed mathematics PBA. Data were collected by administering the PBA to 750 senior high …

Exploring Preservice Teachers' Development Of Collective Mathematics Identity Through Community Building, Paula Santana De Tice

Electronic Theses and Dissertations, 2020-2023

In recent years, attention to equity and inclusion has rightfully become an essential focus in mathematics education. Given the social nature of mathematics, collaborative learning is one of the instructional strategies with the greatest potential for developing conceptual learning and creative problem-solving, and when facilitated well, has the potential to minimize racial and social biases. However, although the expected outcome of student collaboration is a collective mathematical agency, studies show that for this to happen, it is first necessary to develop among students Collective Mathematics Identity, which are beliefs and dispositions developed by a group of students about their collective …

Supporting Secondary Teachers' Proof And Justification Of Calculus Concepts Through The Intentional Use Of Dynamic Technology, Shahabeddin Abbaspour Tazehkand

Electronic Theses and Dissertations, 2020-2023

Learning calculus concepts plays a huge role in understanding phenomena in STEM-related disciplines. Those concepts tend to be dynamic in nature, and the visual exploration and representation of calculus concepts using paper and pencil is limited compared to pedagogically and intentionally using dynamic geometry software. As such, a primary component of this dissertation study involves the integration of dynamic technology. Additionally, previous studies have shown that students have difficulties constructing proofs related to calculus concepts. Despite the existing body of research on students' comprehension of proof and justification, there has not been much focus on teachers' knowledge and perception of …

Cover-Copy-Compare As A Math Fact Fluency Intervention For Students In An Alternative Special Education Program, Raelynn J. Lamminen

All Graduate Theses, Dissertations, and Other Capstone Projects

Cover-Copy-Compare (CCC) has been identified as an empirically supported and socially valid intervention for promoting math fact fluency across instructional settings. However, limited research has investigated the effectiveness of CCC as a math fact fluency intervention within the setting IV environment with even fewer studies including behavioral measures as a dependent variable. Therefore, this study investigated the effects of CCC as a math fact fluency intervention with four 4th-6th grade students within the setting IV environment with math fluency deficits. Using a multiple baseline across participants design, baseline levels of digits correct per minute (DCPM) and on-task behavior were compared …

Identifying Misconceptions About Evolution Relative To Science Curriculum Exposure At The Secondary Level, Rachel Carney

Graduate Research Papers

Evolution is the foundation of the biological sciences. Addressing misconceptions related to biological evolution ensures students have a solid understanding of evolution so that they can become scientifically literate members of society. While studies have identified misconceptions about evolution, there is much less research on the degree to which specific biology curricula address these misconceptions. The goal of this study is to determine how exposure to the SEPUP biology curriculum affects the misconceptions about evolutionary theory held by 10th grade students.

This study took place at a moderately-sized school located in the Midwest. Students respond with their agreeability to a …
