Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I (GCI), reintroduced in Organic Chemistry I (OCI), and then utilized throughout other higher-level chemistry courses. Student difficulties with resonance are well documented. Instruction is one potential source of student difficulties. What instructors…

Articulating clear and achievable expectations is fundamental to both education and organizational management. In this article, we provide a simple intervention for clarifying expectations--and establishing that these expectations have been understood--which proved beneficial both to community college interns and to their internship mentors in…

Current science education efforts emphasise the need to train students to understand the nature of scientific work. In geosciences, training students to understand how science works does not only promote their interest and community engagement in the field, but also has the potential to promote awareness and ethics. However, instructional…

This study developed and implemented a learner-centered assessment named Creative Exercises (CEs) in introductory chemistry courses at a four-year university and a two-year community college. CEs were developed and implemented as an intervention for treatment groups. The control groups only used traditional assessments such as multiple-choice and…

There has been a call from the national community of biologists and biology educators to increase biological literacy of undergraduate students, including understanding and application of core concepts. The structure and function relationship is a core concept identified by the wider biology community and by physiology faculty. Understanding of…

Science education reform documents call for students to learn science by engaging in inquiry and using science practices. One such science practice is constructing evidence-based explanations. Few students enter community college science classrooms having experience with, or being proficient in, using evidence to explain scientific phenomena.…

Physics lab instruction is evolving in response to changing technology, a desire to better prepare students for diverse careers, and renewed focus from physics education researchers. To prepare researchers to evaluate progress in instructional labs in the future, this study set out to understand the current state of instructional physics labs in…

It is an established fact that in the United States there is a great need to improve the scientific literacy of undergraduate students, especially those who are nonscience majors. Data presented herein suggest that using simple art concepts can assist nonscience majors in better appreciating scientific facts related to chemistry. However, it is…

The purpose of this study is to explore community college students' reasoning patterns and argumentation within the context of natural selection. Written assessments and interviews were administered to 2-year college students. Participants were given the Lawson Classroom Test of Scientific Argumentation (LCTSR), a Test of Scientific Argumentation…

Chemistry as a subject is difficult to learn and understand, due in part to the specific language used by practitioners in their professional and scientific communications. The language and ways of representing chemical interactions have been grouped into three modes of representation used by chemistry instructors, and ultimately by students in…

Scientific explanations require levels of both precision and generality that are not characteristic of everyday thinking. For example, an equation such as F = ma can be used to make specific predictions across a wide range of situations. How can science instruction help students to appreciate the utility and importance of precise general…

The study attempted to determine whether the use of a series of reading and response assignments decreased students' perceptions of chemistry difficulty and enhanced students' perceptions of the relevance of chemistry in their everyday lives. Informed consent volunteer students enrolled in General Chemistry II at a community college in the…
