Surface structures on the nanometer size scale can impart new and exciting properties to bulk materials. Nanoscopic structures on hydrophobic materials can result in superhydrophobicity and structural coloration. We present an interdisciplinary experiment that introduces undergraduate students to nanotechnology by manipulating the…

Collaboration is an important career skill and vital to student understanding of the social aspects of science, but less is known about relationships among collaborative-learning strategies, classroom climate, and student learning. We sought to increase the collaborative character of introductory undergraduate laboratory classrooms by analyzing a…

Spatial reasoning is defined as the ability to generate, retain, and manipulate abstract visual images. In chemistry, spatial reasoning skills are typically taught using 2-D paper-based models, 3-D handheld models, and computerized models. These models are designed to aid student learning by integrating information from the macroscopic,…

Recent research indicates that students are adopting a consumerist approach to education, while data shows that the best academic outcomes are associated with intrinsic motivation. The goal of the study was to explore student academic motivation in an undergraduate Principles of Chemistry I class. The study targeted 432 students enrolled in 9…

Copying adjacent answer sheets on the oft-used multiple-choice exams can be prevented if exam material is scrambled. The latter mode has been a requirement for all exams of this type at McGill University for 26 years. Cheating by copying has been reduced to nearly zero in this time. The experiment carried out used permissive seating and a single…

In this study, a pendulum experimental tool with a light-based timer has been developed to measure the period of a simple pendulum. The obtained data was automatically recorded in an Excel spreadsheet. The intensity of monochromatic light, sensed by a 3DU5C phototransistor, dynamically changes as the pendulum swings. The changed intensity varies…

We report a series of three experiments that introduce students at different stages of their academic preparation to the medical applications of hydrogels for controlled drug delivery and wound healing. The laboratory activity bridges the fundamental concepts of chemistry (acids and bases, equilibria, solvation, and reversible esterification) with…

We present the evaluation of the student response to a novel form of practical assessment: the Practical Skills Portfolio (PSP). The PSP is a concise record of a practical activity for the purposes of assessment, which prompts students to engage in reflective practice on laboratory skills, and provides opportunities for enhanced feedback delivered…

Implementation of active-learning practices into science, technology, engineering, and mathematics (STEM) courses has been shown to increase student learning and performance, improve retention of material, and reduce achievement gaps among different student populations when compared to lecture-based approaches. To this end, we transformed two…

This paper explores the views of pre-service physics teachers and science teacher educators about the initial teacher education (ITE) programs in two Melbourne universities, focusing on their preparation for teaching high school physics. Using a qualitative interview approach, five pre-service physics teachers and three physics teacher educators…

Especially, during the first year in university, absenteeism can have detrimental effects on grades and social integration of the student in the university community. According to pedagogical literature, altering teaching methods from lecturing toward engaging teaching, which applies various active teaching methods in the university classroom, can…

Despite the interest, curiosity and the enthusiasm of the large public for Astronomy as a scientific discipline, it is absent from the current Romanian curriculum. We present here the results of two surveys that involve parents and teachers and show the necessity, the relevance and the usefulness of including astronomy as a discipline in the…

With only minimal changes to the course structure, classroom clickers were introduced in introductory chemistry to allow students to regularly compare their perceived abilities with their actual abilities, a measurement also known as calibration. Students used the clickers to provide knowledge judgments, an indication of their confidence in…

We evaluated student perceptions of an inquiry-based, karaoke video exercise in six university classes ranging from first year to graduate level. Students created a 3-4 minute karaoke video on a topic relevant to class. Student responses to the project based on questionnaires and triangulation interviews were strongly positive. Students did not…

A computational chemistry exercise for the undergraduate physical chemistry laboratory is described. In this exercise, students use the molecular dynamics package Amber to generate trajectories of bulk liquid water for 4 different water models (TIP3P, OPC, SPC/E, and TIP4Pew). Students then process the trajectory to calculate structural (radial…
