The objective of this work was to evaluate the implementation of a metavisual strategy for students to revise and self-regulate concepts arising in a study of a chemical reaction between ions. For this purpose, two chemistry education undergraduate students at a Brazilian public university carried out an investigative activity, involving…

Feedback has a powerful influence on learning. However, feedback practices in higher education often fail to produce the expected impact on learning. This is mainly because of its implementation as a one-way transmission of diagnostic information where students play a passive role as the information receivers. Dialogue around feedback can enhance…

Contribution: A do-it-yourself (DIY) light wave sensing (LWS) and communication project was developed to generate interest and clarify basic electromagnetic (EM) and wireless sensing/communication concepts among students at different education levels from middle school to undergraduate. This article demonstrates the nature of the project and its…

Student preparedness is an essential component of transition to university influenced by a broad suite of attributes including academic aptitude, prior knowledge, self-efficacy, self-confidence and a complex assortment of study and life skills. In the case of chemistry education, students' self-perceptions of preparedness are intrinsically linked…

The mismatch between high school and college learning environments creates a barrier to student success in STEM majors in college. The high school learning environment relies on surface learning in which skills such as re-reading and memorizing are sufficient for academic success. The college learning environment, particularly in STEM disciplines,…

Assessments of scientific reasoning that capture the intertwining aspects of conceptual, procedural and epistemic knowledge are often associated with intensive qualitative analyses of student responses to open-ended questions, work products, interviews, discourse and classroom observations. While such analyses provide evaluations of students'…

In this article, we present a low-cost lab experience, enhanced by new technologies and easy to execute. The objective of the experiment is to explore the moment of inertia of a fidget spinner quantitatively. Our choice was to integrate the teaching of physics with the use of a popular toy, the fidget spinner, very popular among young people and…

This paper describes the design and effectiveness of a 360° (identified as 360) virtual laboratory tour which was implemented in a second-year undergraduate chemistry subject to familiarize the students with the research laboratory environment, equipment, and skills needed to undertake the subject and first laboratory session. We include step by…

Including undergraduate research in STEM education is a well-supported and growing high-impact practice that has been made much more scalable through integrating these experiences into the classroom. Here we describe a new biochemistry Course-based Undergraduate Research Experience (CURE) that follows a design-to-data workflow with a strong…

Many authors suggest that is necessary to include the most important episodes from physics history in teaching and learning in order to give students some ideas about the nature of science. The pendulum-related aspects are considered as very adequate for that purpose. Unfortunately, when some physics textbook authors present historical…

Threshold concepts are fundamental to a discipline and, once understood, transform students' understanding and perception of the subject. Despite the value of threshold concepts as a learning "portal" for heuristic purposes, there is limited empirical evidence of threshold crossing or achieving mastery. As a threshold concept, biological…

Teaching emulsion polymerization is an important benchmark in undergraduate polymer courses. However, the introduction of hands-on experiments in undergraduate polymer laboratories is challenging: experimental time, reagents, and equipment involved are the primary restraints. We report a practical emulsion polymerization laboratory experiment for…

Despite widespread calls for the incorporation of mathematical modeling into the undergraduate biology curriculum, there is lack of a common understanding around the definition of modeling, which inhibits progress. In this paper, we extend the "Rule-of-Four," initially used in calculus reform efforts, to a "Rule-of-Five"…

We present here an extension of Morrison's and Ruder's "Sequence-Response Questions" (SRQs) that allows for more nuance in the assessment of student responses to these questions. We have implemented grading software (which we call ANGST, "Automated Nuanced Grading & Statistics Tool") in a Microsoft Excel sheet that can take…

A multifaceted experiment, accessible to students either in an introductory organic chemistry course or in a more advanced laboratory setting, is described for investigating the addition of dichlorocarbene to E- and Z-[beta]-methylstyrenes. The innovative exercise, which integrates elements of synthesis, mechanisms, instrumental analysis,…
