In this paper we put forth a model for physics course reform that uniquely uses proven, research-based active-learning strategies to help students improve their physics knowledge and problem-solving skills. In this study, we compared the exam performance of students in two sections of the same introductory physics course. One section (the…

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…

This paper highlights the design process and implementation for an "all majors" undergraduate course that allows students a chance to reconnect with the natural world. During this course students explore a wide range of biological and physical science based topics that seek to highlight human intervention and our impacts on the planet.…

The Integrated Concentration in Science (iCons) 4-year program at the University of Massachusetts Amherst was designed to promote interdisciplinary STEM collaboration in the solution of real-world problems and encourage student independence and interdependence through a student-centered teaching approach that structures all projects as group…

One of the major challenges of teaching science has been engaging students in discussions of concepts due to lack of perceived relevancy of topics to students' individual goals and societal issues. Science has been viewed as a set of abstract topics disconnected from the real world. To increase student motivation, self-efficacy, and interest in…

In this article, the authors describe how classroom observations were used to characterize differences in instructional practices among undergraduate science courses. Student and faculty behaviors and dialogues were quantified using the Teaching Dimensions Observation Protocol (TDOP) in introductory science courses across multiple disciplines…

Cellular respiration, the central component of cellular metabolism, can be a difficult concept for many students to fully understand. In this interrupted, problem-based case study, students explore the purpose of cellular respiration as they play the role of medical examiner, analyzing autopsy evidence to determine the mysterious cause of death…

This article describes the implementation of high-altitude balloon (HAB) research into a variety of undergraduate atmospheric science classes as a means of increasing active student engagement in real-world, problem-solving events. Because high-altitude balloons are capable of reaching heights of 80,000-100,000 ft (24-30 km), they provide a…

As strong proponents of problem-based learning (PBL), the authors designed and taught an interdisciplinary, team-taught PBL course on Writing Science for the Public at a midsize northeastern state university. This approach led to emphasizing collaboration and experiential learning and resulted in media-rich student projects.

An essential component skill of monitoring and reflection during problem solving is work checking, a process used by experts while solving problems to determine if their solution is achieving the goal. The results of work checking may reveal errors or inconsistencies, indicating a need for iteration. Using think-aloud interviews, the authors…

In this article, the authors describe a project that was developed for an introductory-level physics course. The aim of the project was to encourage the creative process in science, as science is seldom mentioned in discussions about creativity. They sought to engage students in the creative process by posing a collective challenge to the class.…

In the engineering field, problem- and project-based learning, both of which are often referred to as PBL, are the dominant instructional models called for by accreditation agencies. The aim of this qualitative case study is to analyze and capture a holistic perspective of PBL course design and its implementation in two communication-intensive…

This case study involves the role of the kidneys in regulating blood pH and electrolytes. The case was used near the end of a two-semester Human Anatomy and Physiology course sequence, during the time when renal physiology was under study. Groups of two to three students were given the case and associated information (lab values, etc.). Students…

High failure rates in introductory large lecture chemistry courses for STEM majors have been of concern for years. Through our weekly Team Approach to Successful Learning (TASL) workshops, students learn and apply problem-solving strategies, coached by specially trained peer learning coaches (LCs). These coaches concurrently enroll in Chemistry…

This article presents the combination of three enhanced educational approaches for training future scientists. These methods incorporate skills generally not introduced in the freshman year: student-led blackboard introductions; the writing of scientific papers; and the design, execution, and presentation of an independent lab module. We tested…
