Here, students determine aspirin (acetylsalicylic acid) mass in pharmaceutical tablets using a colorimetric method. Aspirin, salicylate, and salicylic acid do not absorb visible light. Thus, in alkaline medium, acetylsalicylic acid was hydrolyzed to salicylate; then, it was reacted with an acidic Fe(III) solution, and a violet complex was formed.…

In many of our courses, particularly laboratory courses, students are expected to engage in scientific writing. Despite various efforts by other courses and library resources, as instructors we are often faced with the frustration of student plagiarism and related writing problems. Here, we describe a simple Writing in Your Own Voice intervention…

A semester-long, project-based series of laboratory exercises is described that provides practical experience of the upstream and downstream processes involved in monoclonal antibody production. This 6 week project is aimed at final year undergraduate students undertaking primary degrees in biotechnology, biochemistry, or related disciplines.…

Course-based undergraduate research experiences (CUREs) have been shown to lead to multiple student benefits, but much is unknown about how CUREs lead to specific student outcomes. In this study, we examined the extent to which students making "broadly relevant novel discoveries" impacted student project ownership by comparing the…

This article examines how one public university helped address student plagiarism through a collaboration between the Math and Writing Center and the Office of Student Conduct and Integrity. Included is a thorough discussion of how the program was designed, the roles each office played, and how the two areas collaborated to assess success. Since…

Over the years, much criticism against animal use for physiology teaching has been made. Hence, replacement by suitable alternatives has increased in several pedagogical approaches. This study examined students' perceptions of animal versus virtual (video/computer) laboratory classes in physiological sciences associated with the effectiveness of…

Previous research shows that many students find it difficult to learn computer programming. To learn computer programming includes both gaining theoretical understanding and learning to develop programmes in practice. To this end, teachers commonly design programming exercises for the students in the computer laboratory. To be able to improve the…

In order to support physics students in their future careers, there is a need to understand the relationship between undergraduate education and professional practice in physics-related fields. This study investigated high-level goal driven mathematical problem-solving activities that are found within two disciplinary cultures: physical science…

This study suggests an engineering design process-based (EDP-based) teaching and learning model in science education and examines its educational potential for scientifically gifted students. This model consists of activities designed to help students come up with creative solutions using the engineering design process in a methodological manner…

This article describes an experiment that can be done in the classroom in a simple way, with the support of a "homemade" device or as a laboratory practice with the support of PASCO equipment. Through a theory-practice sequence, kinematic and dynamic equations were checked with qualitative and quantitative analysis, emphasizing the…

This paper examines students' engagement in monitoring anomalous results across a 2-year longitudinal study with 9th and 10th graders (14-15 and 15-16 years of age). The context is a set of five inquiry-based laboratory tasks, requiring students to plan and carry out investigations. The study seeks to examine students' interpretation of data, in…

Undergraduates learn that gene editing in diverse organisms is now possible. How targeted manipulation of genes and genomes is utilized in basic science and biomedicine to address biological questions is challenging for undergraduates to conceptualize. Thus, we developed a lab experience that would allow students to be actively engaged in the full…

Drawing on a text-based ethnography of digital writing in a biology laboratory, this article examines the text trajectory of a scientific manuscript and a scientific team's related writing for public audiences, including for citizen scientists. Using data drawn from texts, observations, interviews, and related artifacts, the author examines how…

A laboratory experiment to determine the concentration of the anti-inflammatory drug ibuprofen in liquid gelatin capsule dosage forms, suitable for undergraduate chemistry or pharmacy students, is described. Either individually, or in small teams, the students digest two 200 mg capsules in a KOH solution. While the capsules are digesting the…

In this exploratory qualitative study, we describe instructors' self-reported practices for teaching and assessing students' ability to troubleshoot in electronics lab courses. We collected audio data from interviews with 20 electronics instructors from 18 institutions that varied by size, selectivity, and other factors. In addition to describing…
