Some students struggle with chemistry because they do not find the relevance between chemistry content and their lives or they perceive their intelligence as fixed. Social-psychological interventions (SPIs), brief interventions that target students' subjective experiences, were developed to address these issues. As a result, SPIs have been…

Numerous online resources provide a variety of content for a wide range of STEM topics; however, they tend to function as isolated tidbits that provide content-specific knowledge. Application-based science education videos address the overlooked issue of concept to application by implementing experimental components in their videos and fostering…

The Additive Factor Model (AFM) is a cognitive diagnostic model that can be used to predict student performance on items in a context that allows for student learning. Within AFM, "skills" have a learning rate, and student acquisition of a skill depends only on the number of opportunities a student has had to exercise that skill and the…

This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required…

In large, introductory courses, instructors and teaching assistants often struggle to provide detailed feedback on student homework in a timely manner. Here we describe a peer-reviewed homework system that provides quick turnaround while offering flexibility in the construction of homework problems. Homework is administered through a cycle, which…

This study assessed the impact of flipped instruction on study effort, exam performance, motivation, and perceived class quality in two sections of an introductory chemistry course. Giving frequent assignments and quizzes provided enough incentive to ensure pre-class study compliance, and flipped instruction did not appreciably increase overall…

This action research was completed as a module on an in-service teacher education program and addressed form four (year 10, students aged 14-15 years old) students' demotivation to study chemistry on the Caribbean island of Trinidad. My students often find chemistry challenging, and I suspect that teacher-centered methods probably contribute to…

Two large sections of first-semester general chemistry were assigned to use different homework systems. One section used MindTap, a Cengage Learning product, which presents short sections of the textbook with embedded homework questions; such that students could read the textbook section then answer one or more questions in the same screen. The…

A flipped classroom is one where students are first introduced to content outside of the classroom. This frees up class time for more active learning strategies and has been shown to enhance student learning in high school and college classrooms. However, many studies in General Chemistry, a college gateway science course, were conducted in small…

A first-year chemistry course is ideal for introducing students to finding and using scholarly information early in their academic careers. A four-pronged approach (lectures, homework problems, videos, and model solutions) was used to incorporate library research skills into a large lecture-based course. Pre- and post-course surveying demonstrated…

Online homework assignments have been shown to enhance student performance. Our research on gendered responses to these assignments adds new and useful information. We investigated differences between male and female students' responses to online homework in large-enrollment general chemistry courses. Replacing in class quizzes with online…

The study analyzed 2005 posttest data compared to 2008 posttest data to determine student end of school year academic achievement outcomes across three academic levels (above average, average, and below average chemistry potential) and two teacher homework evaluation methods (assigned but not graded and assigned and graded) on teacher prepared…
