Ítem Applying the Delphi method with early-career researchers to explore a genderissues agenda in STEM education(Modestum LTD, 2022) Hernandez-Martinez, Paul; Dominguez, Angeles; Zavala, Genaro; Kambouri, Maria; Zubieta, Judith; Clark, RobinThe Delphi method (DM) was initially conceived as a forecasting technique whose results are based on the consensus of a panel of experts. It has been used in many fields, assisting researchers, policymakers, and others in setting directions and future agendas. This study presents an application of the DM, with a broader interpretation of the notion of “expert” as a qualitative tool to explore gender issues in science, technology, engineering, and mathematics (STEM) education. Its aim is to analyze the use of the DM as a technique to achieve agreement among a group of early-career researchers from the UK and Mexico, who are not considered “experts” in the traditional sense. The other aim was to explore the advantages and disadvantages of using the DM in this context. We used three stages to collect information and reach a consensus. The first two were online activities, and the last consisted of a five-day face-to-face workshop. In the first stage, participants sent research questions, and organizers categorized them into themes. Participants responded to a survey ranking all research questions in the second stage. In the last, organizers analyzed the highest scored questions and arranged them into research topics in which participants worked on research proposals. The DM worked successfully with this group of participants by combining their interest in the field and engagement with the activities. The research strands and proposals of using this method are usable. The method used in this paper can serve as a model to develop research graduate courses to develop students’ skills © 2022 by the authors; licensee Modestum.

The purpose of this paper is to explore 9th-grade students' perceptions about biology and some of the factors and players that influence them in pursuing an academic or professional career in these fields of knowledge. A 13-item survey graded on a 5-point Likert scale was administered to 350 Mexican students from two states, Chiapas and Nuevo Leon, as part of a broad research project that aims to determine which factors and players influence the perceptions of teenagers, from a gender perspective, about STEM fields. Results show statistically significant differences among group participants in the perceptions of the value of biology to their academic futures (T-Test, p=0.035) between genders in the state of Nuevo Leon (T-Test, p=0.037, 0.083). Results also show significant correlation between parents' levels of education and students' self-efficacy (Pearson correlations). Conclusions drawn from this paper discuss the relatedness of teenagers' STEM perceptions and their academic and professional futures with respect to gender, geographic residency, family and self-efficacy. The research also highlights the need for a profound comprehension of students' appreciation for science, technology, engineering and mathematics. © 2019 IEEE.Ítem Integration of Physics and Mathematics in STEM Education: Use of Modeling(Multidisciplinary Digital Publishing Institute (MDPI), 2024-01) Dominguez, Angeles; De la Garza, Jorge; Quezada-Espinoza, Monica; Zavala, GenaroWithin STEM (Science, Technology, Engineering, and Mathematics) education, integrating real-world problem scenarios is paramount. Within interdisciplinary education, modeling is an approach to fostering student learning and skill development in a student-centered learning environment. This study focuses on an integrated physics and mathematics course in STEM education based on modeling for first-year engineering students. The main objectives of this study are to analyze students’ models, assess the effectiveness of the pedagogical approach, and evaluate the benefits of integrative education. This study uses a Model-Application Activity as a closure for the quadratic model and extends the models built to a two-dimensional motion situation. The core activity involves a real-world experiment where students attempt to roll a ball down a ramp into a cup. While most groups successfully constructed theoretical models, only a few hit the target, highlighting the complexities of applying theoretical knowledge to real-world scenarios. The study also emphasizes the seamless integration of physics and mathematics, enriching the learning experience and making the models more robust and versatile. Despite the promising results, the study identifies a gap between theoretical understanding and practical application, suggesting the need for more hands-on activities in the curriculum. In conclusion, this study underlines the value of integrating physics and mathematics through modeling and a student-centered approach, setting the stage for future research to enhance the effectiveness of STEM education.Ítem Test of Understanding Graphs in Calculus: Test of students' interpretation of calculus graphs(Modestum LTD, 2017) Dominguez, Angeles; Barniol, Pablo; Zavala, GenaroStudies show that students, within the context of mathematics and science, have difficulties understanding the concepts of the derivative as the slope and the concept of the antiderivative as the area under the curve. In this article, we present the Test of Understanding Graphs in Calculus (TUG-C), an assessment tool that will help to evaluate students' understanding of these two concepts by a graphical representation. Data from 144 students of introductory courses of physics and mathematics at a university was collected and analyzed. To evaluate the reliability and discriminatory power of this test, we used statistical techniques for individual items and the test as a whole, and proved that the test's results are satisfactory within the standard requirements. We present the design process in this paper and the test in the appendix. We discuss the findings of our research, students' understanding of the relations between these two concepts, using this new multiple-choice test. Finally, we outline specific recommendations. The analysis and recommendations can be used by mathematics or science education researchers, and by teachers that teach these concepts. © Authors.
