The increase in classroom technology has resulted in the use of clickers and other audience response systems (ARS) for simultaneous reporting of choices in the teambased learning (TBL) classroom. A variety of techniques and practices using ARS technology in TBL courses has been noted. Learning gains in the TBL classroom with ARS reporting has not…

There is a growing interest in engaging students and the general public about the meaning and objectives of doing science. When it is possible students can learn by actively engaging in the practices of science, conducting investigations, sharing ideas with their peers, teachers and scientists, learning to work with measuring apparatuses, to…

Homework in introductory physics represents an important part of a student's learning experience; therefore, choosing the manner in which homework is presented merits investigation. We performed three rounds of clinical trials comparing the effects of mastery-style homework vs. traditional-style homework with students in both algebra-based and…

Chemical identity, the idea that every substance has at least one property that makes it unique and able to be differentiated from other substances, is core to the practice of chemistry. Such practice requires using properties to classify as well as to differentiate. Learning which substance properties are productive in chemical identity thinking…

Instead of flipping a conventional college course, here we consider flipping part of a conventional course into a whole new course. The idea tested here for three semesters was to split a full-featured traditional course into two linked courses: a condensed, 1-credit-hour, online mass-enrollment course on core ideas and skills paired with a…

In recent years, commissions and reports have called for laboratory courses that engage undergraduates in authentic research experiences. We present an iterative approach for developing course-based undergraduate research experiences (CUREs) that help students learn scientific inquiry skills and foster expert-like perceptions about biology. This…

A major research thrust in science, technology, engineering, and mathematics (STEM) education is focused on how to retain students as STEM majors. The accumulation of seemingly insignificant negative experiences in STEM classes can, over time, lead STEM students to have a low sense of belonging in their disciplines, and this can lead to lower…

Physics laboratory courses have been generally acknowledged as an important component of the undergraduate curriculum, particularly with respect to developing students' interest in, and understanding of, experimental physics. There are a number of possible learning goals for these courses including reinforcing physics concepts, developing…

Engaging students in research has the potential to benefit students, faculty, and institutions. The authors present a case study documenting strategic efforts to advance a culture of undergraduate research at Hunter College, City University of New York. Assembling a team, removing obstacles, increasing awareness and engagement, identifying goals,…

National Research Council polices (NRC, 2012a, 2012b) and the Every Student Succeeds Act (ESSA) of 2015 (Pub. L. No. 114-145) call for educators to have active roles in teaching to achieve new goals and purposes for education. A high priority is teaching content knowledge and information fluency skills that will result in deep learning, higher…

We used an "approach to learning" theoretical framework to explicate the ways students engage in scientific modeling. Approach to learning theory suggests that when students approach learning deeply, they link science concepts with prior knowledge and experiences. Conversely, when students engage in a surface approach to learning, they…

An elective course, "Toward the Greening of Our Minds": Green and Sustainable Chemistry, has been offered at Washington College since 2005. This new course without laboratory is designed for chemistry and biology majors and minors who have previously taken two semesters of general chemistry and organic chemistry. Due to the popularity of…

Environmentalism's wider and wilder possibilities today appear as regions of seeming darkness that bracket or frame acceptable environmental thinking. One of these barely-mentionable darknesses is outer space--the cosmos. Another is the inner and chthonic powers of the land and natural beings generally. This essay aims to bring these two kinds of…

Recently, 57 undergraduate students at the University of Michigan were assigned the task of solving a crystal structure, given only the electron density map of a 1.3 Å crystal structure from the electron density server, and the position of the N-terminal amino acid. To test their knowledge of amino acid chemistry, the students were not given the…

Prediction of number of [Pi]-bonds, [sigma]-bonds, single and triple bonds of aliphatic unsaturated open-chain and cycloalkynes is a vitally important tool for students of chemistry at undergraduate and graduate level for solving different kinds of problems regarding different chemical reactions. In this manuscript, we try to present a simple and…
