This multiple case study investigated how college students with diverse ethno-linguistic backgrounds used chemistry vocabulary as a way to look at their discursive identities and cultural border crossings during first semester general chemistry laboratories. The data were collected in two major forms: video-taped laboratory observations and…

A virtual learning environment can engage university students in the learning process in ways that the traditional lectures and lab formats cannot. We present our virtual learning environment "StudentResearcher," which incorporates simulations, multiple-choice quizzes, video lectures, and gamification into a learning path for quantum…

Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved…

A well-ordered biological complex can be formed by the random motion of its components, i.e. self-assemble. This is a concept that incorporates issues that may contradict students' everyday experiences and intuitions. In previous studies, we have shown that a tangible model of virus self-assembly, used in a group exercise, helps students to grasp…

Today's generation often seeks help from each other in online environments; however, only a few investigated the role of Internet technologies and the nature of online help-seeking behavior in collaborative learning environments. This paper presents an educational design research project that examines college students' online help-seeking…

Many science educators know of the pedagogical benefits of inquiry- and research-based labs, yet numerous barriers to implementation exist. In this article we describe a faculty development workshop that explored interdisciplinary and inter-institutional collaborations as potential mechanisms for overcoming barriers to curricular innovation.

Globally, mathematics and science pass rates at school level have been a much discussed and researched issue. Teachers are tasked with the responsibility of alleviating learners' challenges associated with the learning of mathematics and science. Thus, teachers are pursuing innovative techniques for improving the understanding of and increasing…

Currently, there are a number of educational applications that allow students to reinforce theoretical or numerical concepts through an interactive way. More precisely, in the field of the analytical chemistry, MATLAB has been widely used to write easy-to-implement code, facilitating complex performances and/or tedious calculations. The main…

We describe a laboratory experiment that employs the Nanoceria Reducing Antioxidant Capacity (or NanoCerac) Assay to introduce students to portable nanoparticle-based paper sensors for rapid analysis and field detection of polyphenol antioxidants. The experiment gives students a hands-on opportunity to utilize nanoparticle chemistry to develop…

This study was designed to analyze the procedural fluency and written-mathematical explanation to select constructed response tasks of students in Thermodynamics problems. The study made use of 2 sections, composed of 26 students, in University Physics 1 to conclude on the research problem. It made use of the assumption that mathematical and…

Due to progress in nanotechnology high-quality quantum wires can nowadays be fabricated. The behavior of particles in one dimension differs significantly from that in three-dimensional (3D) systems, yet the physics of such low-dimensional systems is generally not very well represented in standard undergraduate or graduate curricula. For instance,…

Photochemical upconversion is a regenerative process that transforms lower-energy photons into higher-energy light through two sequential bimolecular reactions, triplet sensitization of an appropriate acceptor followed by singlet fluorescence producing triplet-triplet annihilation derived from two energized acceptors. This laboratory directly…

We have incorporated an active-learning assignment, Reading Papers Using Key Sentences, in an upper-level Introduction to Chemical Research course. Although key sentences are typically used to help authors write with clarity and organization, we have found that this assignment helps students improve upon and practice reading journal articles for…

In this paper, we report on a project concerned with the role of cognition during problem solving. We specifically explore the categories of mental representations that students work with during problem solving of different representational task formats. The sample, consisting of 19 engineering students taking a calculus-based physics course,…

We have examined the teaching practices of faculty members who adopted research-based instructional strategies (RBIS) as part of the Carl Wieman Science Education Initiative (CWSEI) at the University of British Columbia (UBC). Of the 70 that adopted such strategies with the support of the CWSEI program, only one subsequently stopped using these…
