Chemical representations serve as a communication tool not only in exchanges between scientists but also in chemistry lessons. The goals of the present study were to measure the extent of student teachers' knowledge about chemical representations, focusing on chemical formulae and structures in particular, and to explore which factors related to…

This paper describes the use of an inexpensive smartphone's magnetic sensor to measure magnetic field components (B[subscript x], B[subscript y] and B[subscript z]) induced by current wires in magnetostatic experiments. The variable parameters used to measure the magnetic sensor's capabilities were: the geometrical shapes of the wire, current…

Clickers are often used as an active learning tool in face-to-face classes to enhance student engagement and assess student learning. In this article we share the variety of ways that we use clicker questions to promote deliberate practice in large science courses. Deliberate practice is the use of specifically structured exercises that develop…

Online student-response systems provide instructors with an easy-to-use tool to instantly evaluate student comprehension. For comprehensive content review, turning this evaluation into a competitive game where students can compete against each other was found to be helpful and enjoyable for participating students. One specific online resource,…

The different ways microscale and green chemistry allow reducing the deleterious impacts of chemistry on human health and the environment are discussed in terms of their different basic paradigms: green chemistry follows the ecologic paradigm and microscale the risk paradigm. A study of the synthesis of 1-bromobutane at macro- ? microscale (109.3…

This study investigated relationships between the thinking processes that 28 undergraduate chemistry students engaged in during guided discovery and their subsequent success at reasoning through a transfer problem during an end-of-semester interview. During a guided-discovery laboratory module, students were prompted to use words, pictures, and…

Research suggests that introductory physics students often have difficulty using a concept in contexts different from the ones in which they learned it without explicit guidance to help them make the connection between the different contexts. We have been investigating advanced students' learning of quantum mechanics concepts and have developed…

As part of ongoing investigations into student learning in advanced undergraduate courses, we have developed a conceptual assessment tool for upper-division electrodynamics (E&M II): the Colorado UppeR-division ElectrodyNamics Test (CURrENT). This is a free response, postinstruction diagnostic with 6 multipart questions, an optional 3-question…

The purpose of this work is to study the effectiveness of our introductory mechanics instructions in changing students' misconceptions about Newtonian concepts. We gave the force concept inventory (FCI) test to 341 of our students twice, before and after instructions. The data were analyzed using a method first reported by Martín-Blas "et…

With the goal of increasing the immediacy of the relationship between tenure-track professors and students, science departments in liberal arts colleges may try to arrange their curriculum so that students have the same professor in both the lecture and the lab section of introductory courses. While this goal seems laudable, empirical data are…

This study presents a review of the current state of research on teaching quantum mechanics in secondary and lower undergraduate education. A conceptual approach to quantum mechanics is being implemented in more and more introductory physics courses around the world. Because of the differences between the conceptual nature of quantum mechanics and…

Serious games seem to be a promising alternative to traditional practices for learning. Recently, their use in computer science education and learning programming became more widespread. Actually, many students in programming courses have difficulties to master all required competencies and skills especially at introductory level and games have…

Students in undergraduate premedical anatomy courses may experience suboptimal and superficial learning experiences due to large class sizes, passive lecture styles, and difficult-to-master concepts. This study introduces an innovative, hands-on activity for human musculoskeletal system education with the aim of improving students' level of…

Revising standard structured academic programs by incorporating research throughout the curriculum is a modern trend at universities worldwide. There are numerous publications on inquiry-based learning (IBL) in individual courses, but few provide evidence both of success at the program level and of synergy in the teaching--research nexus. Our…

Employers of chemistry graduates are seeking a range of transferable skills from prospective employees, and academics are increasingly seeking to build employability skill development opportunities into the undergraduate curriculum. However, research suggests that undergraduates do not recognise or value such skill development without prompting.…
