What and how instructors assess understandably impacts student learning and performance in undergraduate science courses. However, there is limited research on the ways in which assessment practices might be altered to combat inequitable outcomes in these settings. Here we characterize the nature of assessment questions in one second-semester…

Many students experience a language-related barrier which may keep them from fully understanding and engaging in complex chemistry content. Although dense and technically rich scientific language is challenging for most students to interpret, it can become a systematic barrier for English Language Learner (ELL) students when it cognitively…

Chemistry faculty instructors (FIs) and graduate student instructors (GSIs) regularly engage in the evaluation and grading of student responses in formal formative and summative assessments. In this study, we identified dimensions of variation in these instructors' approaches to the evaluation and grading of students' answers. Using qualitative…

The COVID pandemic forced many higher education institutions to pivot and switch to an online learning environment with minimal preparation. This transition was put in place during the middle of the spring semester, in March. During this transition, instructors had to quickly learn the tools of online teaching, navigate platforms like Webex and…

Hydrothermal synthesis and characterization of titanosilicate ETS-10 was used as a means to prepare students for a research-focused independent term project as part of a 200-level descriptive inorganic chemistry course. Students spent the first 7 weeks of the course learning synthesis and characterization techniques that are common for metal oxide…

The New Haven Local Section of the American Chemical Society held a virtual version of its annual Student Research Symposium prompted by the COVID-19 pandemic. A combination of YouTube, Google Drive, Open Broadcaster Software, and Zoom was utilized to hold the symposium which included juried oral and poster presentations. While our aim was to…

This communication describes a variety of virtual student assessment strategies employed at the University of Toronto during the academic disruption caused by the 2020 COVID-19 global pandemic. Instructors focused their efforts toward maintaining a positive learning environment and offering meaningful evaluation methods for students in each of…

The ability to assess students' content knowledge and make meaningful comparisons of student performance is an important component of instruction. ACS exams have long served as tools for standardized assessment of students' chemistry knowledge. Because these exams are designed by committees of practitioners to cover a breadth of topics in the…

Experimental design is a desirable outcome of laboratory education. Incorporating inquiry into the laboratory curriculum is attractive, but there are acknowledged concerns from practical, theoretical, and epistemological perspectives, and these are accentuated in upper-division courses. In this work, we draw on the extensive literature relating to…

The teaching lab is an important component of training and developing undergraduate chemistry students. The lab provides a complex teaching environment where faculty address a number of student-centered goals, including the development of technical proficiency, demonstrations of theoretical concepts, promotion of teamwork, and modeling of data…

We investigated whether use of an adaptive-responsive online homework system (OHS) that tailors homework to students' prior knowledge and periodically reassesses students to promote learning through practice retrieval has inherent advantages over traditional-responsive online homework. A quasi-experimental cohort control post-test-only design with…

Analytical method transfer (AMT) and dissolution testing are important topics required in industry that should be taught in analytical chemistry courses. Undergraduate students in senior level analytical chemistry laboratory courses at Kennesaw State University (KSU) and St. John Fisher College (SJFC) participated in development, validation, and…

In this paper, insight into forensic science students' experiences of a case-based scenario with an interdisciplinary guided-inquiry experience in chemistry and biology is presented. Evaluation of student experiences and interest showed that the students were engaged with all aspects of the case-based scenario, including the curriculum theory…

Getting students to use grading feedback as a tool for learning is a continual challenge for educators. This work proposes a method for evaluating student performance that provides feedback to students based on standards of learning dictated by clearly delineated course learning outcomes. This method combines elements of standards-based grading…

Organic chemistry is often promoted as a course designed to cultivate skill in scientific "ways of thinking." Expert organic chemists perceive their field as one in which plausible answers to complex questions are arrived at through analytical thought processes. They draw analogy between problem solving in organic chemistry and diagnosis…
