The idea that misconceptions must be addressed to improve learning is helpful to remember when developing a case study. Students will bring their existing…

M3CA is a model of mastery learning developed in a college classroom, and an acronym for Mastery, Concept Maps, Critical Thinking, Collaboration and Assessment. The M3CA model is a formative model of skill based mastery learning and assessment that produces high levels of academic achievement and empowers students with a feeling of fairness.…

Active learning in class helps students develop deeper understanding of chemical engineering principles. While the use of multiple-choice ConcepTests is clearly effective, we advocate for including student writing in learning activities as well. In this article, we demonstrate that word clouds can provide a quick analytical technique to assess…

Professors who teach introductory astronomy to students not majoring in science desire them to comprehend the concepts and theories that form the basis of the science. They are usually less concerned about the myriad of detailed facts and information that accompanies the science. As such, professors prefer to test the students for such…

A Chemistry Concept Reasoning Test was created and validated providing an easy-to-use tool for measuring conceptual understanding and critical scientific thinking of general chemistry models and theories. The test is designed to measure concept understanding comparable to that found in free-response questions requiring explanations over…

Hierarchical graphs represent relationships between objects (like computer file systems, family trees etc.). Graph nodes represent the objects and interconnecting lines represent the relationships. In two experiments we investigated what concepts are necessary for understanding hierarchical graphs, what misconceptions evolve when some of the…
