The aim of this study was to examine 6th-grade students' mathematical abstraction processes related to the concept of variable by using the teaching experiment method and to reveal their learning trajectories in the context of the RBC+C model. A teaching experiment was administered to a class of 29 middle school students for 3 weeks. Observations,…

The purpose of this quasi-experimental study was to compare the effects of new developmental statistics-based courses to traditional algebra-based developmental courses. The study used extant data from eight institutions and a matched sample of 2,041 students (Treatment, N = 748; Comparison, N = 1,293). All students enrolled in a treatment or…

This study aims to describe the ability of students' mathematical connections in solving problems in the circle equation material through transposition studies. The method in this research is a descriptive qualitative approach, the techniques used in the study are tests, interviews, and documentation to explore data in research. Test and interview…

Arduino microcontrollers are becoming increasingly popular in the physics/astronomy community. These devices can provide more in-depth labs on mechanics, electricity and magnetism, light and optics, etc., in addition to programming. These devices can be readily utilized to reach more non-physics/astronomy majors and underrepresented STEM students.…

It is difficult for research in Mathematics Education to have any real impact on teaching practice in the classroom. Conscious of this, we have developed a research model for curricular innovation, involving the teachers responsible for its implementation, improving their training, and providing scientific information whilst maintaining the…

Online educational technologies offer opportunities for providing individualized feedback and detailed profiles of students' skills. Yet many technologies for mathematics education assess students based only on the correctness of either their final answers or responses to individual steps. In contrast, examining the choices students make for how…

With limited time available in the classroom, e-learning tools can supplement in-class learning by providing opportunities for students to study and learn outside of class. Such tools can be especially helpful for students who lack adequate prior preparation. However, one critical issue is ensuring that students, especially those in need of…

Online learning platforms integrating open educational resources (OERs) are increasingly adopted in secondary education as supplemental resources for teaching and learning. However, students report difficulties sustaining their engagement because of the self-paced nature of OER-supported learning environments. We noted that little attention has…

This study was to support the understanding of the set structure, binary operations, and their properties as a prerequisite of group theory material categorized as 9 structure senses. This study aimed at investigating the process of students' structure sense in recognizing the structure of mathematical properties or objects as a prerequisite of…

Use of online credit recovery is a growing trend across the country, with the hope that expanding credit recovery options through online courses will help students get back on track toward graduation (e.g., Atkins, Brown, & Hammond, 2007; Gemin, Pape, Vashaw, & Watson, 2015). But expanded use of online credit recovery for high school…

Community colleges serve a vital role in the education of science, technology, engineering, and mathematics (STEM) majors in the United States, however, most research to date on STEM pipeline persistence from academia to the workforce has focused on four-year colleges, which limits understanding of the potential of two-year pathways in…

This program evaluation examined the perceptions of secondary Teacher Development Specialists (TDS) regarding their coaching competencies in English language arts (ELA), mathematics, science, social studies, literacy, and instructional technology. Moreover, the study assessed the extent secondary TDS' coaching practices improved teachers'…

Two set of studies were conducted to better understand grades and grading practices in physics courses, and how these might influence demographic representational disparities in physics. The first study investigates the relationships between grades and the student-level factors of standardized test scores, (binary) gender, underrepresented…

This study sought to answer the following questions: (1) Is it feasible to develop Academic Key Performance Indicators (KPIs) and collect data on them across member urban school districts? (2) Are comparisons between districts on academic performance measures valid and reliable? (3) Do districts collect and maintain requested KPI data in a way…

Background/Context: Research links advanced mathematics course-taking to important later outcomes, including college graduation and earnings, yet many students fail to progress into higher math courses as they move through high school. Black and Hispanic high school students are less likely than their white peers to take advanced math courses. A…
