- Mathematics Anxiety and Self-Efficacy of Mexican Engineering Students: Is There Gender Gap?(MDPI, 2022-06-07) Morán Soto, Gustavo; González Peña, Omar Israel; https://ror.org/03ayjn504Studies have reported that there is a gender disparity wherein women do not study equally to men in bachelor’s degrees in science, technology, engineering, and math (STEM) areas, although they lead the race of having a better terminal efficiency rate in higher education. This research explores engineering students’ math anxiety and math self-efficacy levels, aiming to determine if there is a gender gap for this specific population. Data were collected from 498 students using adapted items from existing surveys. These items were translated to Spanish, and validity tests were used to establish content validity and reliability. A multivariate analysis of variance (MANOVA) was used to determine possible differences between male and female math anxiety and math self-efficacy levels. Male engineering students reported higher self-efficacy and lower math anxiety levels, and this difference was shown to be significant according to the MANOVA results. Findings of this research could help engineering educators to better understand how their students feel when they are practicing and performing math-related activities and what type of strategies could be designed when aiming to ameliorate female students’ math anxiety feelings.
- Effects of a Thermal Inversion Experiment on STEM Students Learning and Application of Damped Harmonic Motion(MDPI, 2021-01-18) Gonzalez Peña, Omar Israel; Morán Soto, Gustavo; Rodríguez Masegosa, Rodolfo; Rodríguez Lara, Blas Manuel; GONZALEZ PENA, OMAR ISRAEL; 162547; Instituto Tecnológico y de Estudios Superiores de MonterreyThere are diverse teaching methodologies to promote both collaborative and individual work in undergraduate physics courses. However, few educational studies seek to understand how students learn and apply new knowledge through open-ended activities that require mathematical modeling and experimentation focused on environmental problems. Here, we propose a novel home experiment to simulate the dynamics of a flue gas under temperature inversion and model it as damped harmonic motion. After designing and conducting the experiment, twenty six first year students enrolled in STEM majors answered six qualitative questions to inform us about their epistemological beliefs regarding their learning process. Their answers imply that this type of open-ended experiments may facilitate students’ understanding of physical phenomena and point to the significance of physics instructors as promoters of epistemological development. In general, students described this activity as a positive experience that helped them connect an environmental phenomenon with a fundamental physics concept.
- Is It a Good Idea for Chemistry and Sustainability Classes to Include Industry Visits as Learning Outside the Classroom? An Initial Perspective(MDPI, 2021-01-14) Gonzalez Peña, Omar Israel; Peña Ortiz, María Olivia; Morán Soto, Gustavo; GONZALEZ PENA, OMAR ISRAEL; 162547; Instituto Tecnológico y de Estudios Superiores de MonterreyLearning outside the classroom (LOtC) activities are part of pedagogical methodologies that are currently applied in the development of student skills. The objective of this study is to determine the perceptions of faculty and undergraduate students concerning industrial visits and define the advantages and disadvantages of these activities. A survey was designed with 17 questions, from a sample of 296 students and 32 professors from various chemistry and sustainability courses. The statistical samples correspond to a population of 2275 students and 246 professors. Descriptive statistics were used to analyze and compare participant perceptions on industrial visits, as LOtC activities. Results indicated a positive perception for making industrial visits, generating more interest in the class material and helping students acquire knowledge. Despite this positive perception, it was found that professors are unlikely to organize industrial visits frequently due to the work required to plan, perform, and evaluate these activities. This issue suggests that approximately 40% of the students may lose the advantages that LOtC activities could offer. Professors must be motivated and supported by administrators to include industrial visits in their courses as a teaching strategy to provide a beneficial experience to the majority of students enrolled in chemistry and sustainability undergraduate programs.
