Recently there has been a push for more student-centered learning in the undergraduate classroom as a way to enhance student learning outcomes. One tool utilized in many Anatomy and Physiology courses is case studies of the material being presented. These allow students to apply their knowledge to a real-world scenario they may encounter in their…

The purpose of this laboratory experiment is to study fundamental concepts of kinetics and equilibria and the isotope effects associated with both of these concepts. The concepts of isotopes in introductory and general chemistry courses are typically used within the contexts of atomic weights and radioactivity. Kinetic and equilibrium isotope…

Existing research identifying common student ideas about forces focuses on students' misunderstandings, misconceptions, and difficulties. In this paper, we characterize student thinking in terms of resources, framing student thinking as continuous with formal physics. Based on our analysis of 2048 written responses to conceptual questions, we…

Prior research has established that students often underprepare for midterm examinations yet remain overconfident in their proficiency. Research concerning the testing effect has demonstrated that utilizing testing as a study strategy leads to higher performance and more accurate confidence compared to more common study strategies such as…

We implemented a laboratory curriculum reform to teach foundational concepts in chemistry, particularly those concepts related to healthcare, in a chemistry course for prenursing students. Here, we discuss the reform, exploring how students built upon understandings gained in lab and correlating lab learning to course outcomes. We further discuss…

Isothermal titration calorimetry was used to experimentally determine thermodynamic values for the ethylenediaminetetraacetic acid (EDTA)(aq) + M[superscript 2+](aq) reactions (M[superscript 2+] = Ca[superscript 2+] and Mg[superscript 2+]). Students showed that for reactions in a N-(2-hydroxyethyl)piperazine-N"-ethanesulfonic acid (HEPES)…

Recruitment and retention in the sciences is both difficult and crucial, especially in the community college setting. In this study, the resources used by General Chemistry I students at two different public, predominantly two-year colleges in two states were studied via surveys for a semester. Data were analyzed with respect to student attitudes…

This article advances the prerequisite network as a means to visualize the hidden structure in an academic curriculum. Networks have been used to represent a variety of complex systems ranging from social systems to biochemical pathways and protein interactions. Here, I treat the academic curriculum as a complex system with nodes representing…

Increasing costs and decreasing numbers of university Extension faculty have made it difficult to provide quality turfgrass short course education. In response, faculty from nine institutions collaborated to develop the Great Lakes School of Turfgrass Science. This 12-week online course provides students with unique learning experiences through a…

"Vision and Change," a publication by the American Association for the Advancement of Science, has illustrated the need for curricular change within biology departments across the nation. Yet despite this apparent need for change, many institutions have been slow to move for a number of reasons, perhaps most significant among them is a…

Collaborative learning involves an interdependence between success of the individual and success of the group, requiring both personal preparation and teamwork. Asynchronous work, in combination with group interaction and problem solving, differentiates collaborative learning from other interactive teaching methods. In this study, three professors…

Organic chemistry courses can present major obstacles to access for students with blindness or low vision (BLV). In recent years, efforts have been made to represent organic chemistry concepts in tactile forms for blind students. These methodologies are described in this manuscript. Further work being done at Illinois State University is also…

This paper is part of a series of studies to improve the efficacy of online physics homework activities by integrating narrated animated solutions with mastery inspired exercises. In a clinical study using first- and second-year university students, the mastery group attempted question sets in four levels, with animated solutions between each…

Narrated animated solution videos were implemented in a clinical study that compared a mastery setting that employed repeated cycles of testing with instructional support to a group that had a single opportunity to experience the materials. The mastery setting students attempted sequential questions sets on a topic, with animated solutions between…

Recently, powerful new observations and advances in computation and visualization have led to a revolution in our understanding of the structure of the Universe. As the field of cosmology advances, it is of interest to study how student ideas relate to scientific understanding. In this paper, we examine in-depth undergraduate students' ideas on…
