Gateway science courses are an ongoing obstacle to recruitment into STEM fields (Science, Technology, Engineering, and Mathematics). Students come into courses that have a high cognitive load, which makes success in the course challenging. Instructional design can be used to reduce cognitive load. The findings demonstrate that leveraging pre- and…

In this article, we discuss Micro Assignment Guided Inquiry and Collaboration (MAGIC), an active learning method that draws on the merits of inquiry-based learning in STEM courses. We describe the use of Micro Assignments (MAs) consisting of a series of short, instructive guiding questions that scaffold the course material. Students work through…

This paper describes an introductory biology course for undergraduates that heavily incorporates quantitative problem solving in activities and homework assignments. The course is broken up into a series of units, each organized around a motivating biological question or theme. Homework assignments address the theme or question, and typically…

"Cases are stories with a message. They are not simply narratives for entertainment. They are stories to educate" (Herreid, 1997, p. 92). By this definition, a case study is two things: a story and a strategy to drive learning. Although the story typically comes from a narrative purposefully written for the classroom, such as the case…

This article reports on students' experiences of the lectorial approach that was implemented for health science students studying sciences at a South Australian university. A lectorial, based on active student-centered learning, is a newly-designed teaching method for a large-scale class employing interactive activities to enhance student…

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…

Many large-lecture introductory science courses for nonscience majors do not have a lab component and hence do not provide much opportunity for students to engage in the practice of science. I have developed a new instructional activity called Dorm Room Labs that enables students to conduct hands-on activities as homework (or dorm room work) to…

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…

This article discusses the results of a survey that was posted for those who regularly peruse the website of the National Center for Case Study Teaching in Science (NCCSTS). Faculty members were asked about their use of case studies and videos in their General Biology classrooms. The results are enlightening because General Biology is arguably the…

New technological developments have minimized training, hardware expense, and distribution problems for the production and use of instructional videos, and any science instructor can now make instructional videos for their classes. We created short "Khan style" videos for the topic of buffers in biochemistry and assigned them as…

This six-year study involved an evaluation of whether student-learning gains for an online homework system that emphasized areas in which students are known to have difficulties--molecular-level conceptualization and visualization, and being able to recognize and relate a concept when it is represented symbolically, numerically, or visually--could…

Creative exercises (CEs) are a form of assessment in which students are given a prompt and asked to write down as many distinct, correct, and relevant facts about the prompt as they can. Students receive credit for each fact that they include that is related to the prompt and distinct from the other facts they list. With CEs, students have an…

This case explores the aggressive mimicry behavior of "femmes fatales" fireflies--female fireflies in the genus Photuris that mimic the flash pattern of females in the genus Photinus to lure Photinus males to their death. The case features entries in an old field notebook as well as a series of handouts that the instructor presents to students for…

College science teachers know that students get the most out of class if they have completed the assigned reading. To reinforce this expectation, we ask our introductory physics students to submit a question they had about the reading. In this paper we describe the rationale and logistics of this assignment. (Contains 2 tables and 2 figures.)

A homework problem that can be graded quickly, involve students in problem solving, and provide feedback on their problem-solving ability is described. A two-part homework problem is assigned: part one stated in the usual manner, and part two consisting of a description with segments left blank for students to fill in. (Author/JN)
