Research on conceptual understanding is one of the first steps in designing materials to improve learning. Literature reports that students have difficulties analyzing and describing phenomena in electric circuits. This report contributes to students' conceptual difficulties regarding simple electrical circuits by systematically analyzing an open conceptual test answered by 531 first-year engineering students. We found students' reasoning that has not yet been reported in the literature as misconceptions or difficulties. To deepen our understanding of students' difficulties, we chose five students by convenience to interview. We present evidence that there are two main contributions to the taxonomy in this study: the Series Circuit Misconception, which is when students convey that the current through bulbs is the same because they are in series, using that as a mnemonic ignoring any change in the circuit; and the Inverse Parallel Circuit Misconception, that is when students mention that the resistance of the circuit decreases when disconnecting bulbs in parallel, neither are reported in the literature. The results of this study have implications for physics education research in electric circuits and educational practice in the classroom.

Higher education institutions have focused their efforts on promoting research seedbeds as a strategy for formative research. In this regard, the impact of such a strategy remains unknown due to the lack of models that enable its evaluation. Therefore, this study aimed to design an evaluation model for the academic productivity of research seedbeds based on the available evidence in the literature. To achieve this, a systematic review was conducted following the PRISMA model, analyzing 53 documents including articles, book chapters, and conference proceedings from the SCOPUS, ProQuest, Jstor, Scielo, and ScienceDirect databases. The results identified indicators that allowed for the design of a model based on six constructs: research training, institutional capabilities, bibliographic production, innovation and development, social appropriation of knowledge, and human resource training. It was concluded that the indicators evaluating research seedbeds seek greater scientific development involving students and improving the quality of research products, which directly impacts the institutional research mission.

This study aimed to evaluate the impact of problem-based learning (PBL) within a teaching unit on the advancement of ethical reasoning and decision-making skills among Israeli female tertiary students. Employing a quasi-experimental design, 48 female students were distributed into three groups, with two serving as control groups receiving conventional curriculum-based instruction and one as an experimental group exposed to the PBL methodology. Both before and after implementation, all groups underwent assessments using a decision-making competency test and an ethical reasoning scale. The results unequivocally demonstrated the significant enhancement of decision-making abilities and ethical thinking through the implementation of the PBL strategy. Comparative analysis revealed substantial improvements in the experimental group compared to the control groups, emphasizing the efficacy of PBL in fostering comprehensive skill development. Furthermore, a positive correlation between ethical thinking and decision-making skills further reinforces the beneficial outcomes associated with PBL. These findings advocate for the widespread integration of PBL techniques across various academic disciplines.
