Assessments that are open-ended and student-centered may be used to encourage formation of networks between prerequisite material and new course content thereby promoting meaningful learning. Creative Exercises (CEs) are assessments that allow multiple correct answers and do not penalize for incorrect statements thereby inspiring creativity. CEs…

In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by…

In this paper, the development of an automatic assessor is presented, both in MATLAB and in Excel, for an analytical exercise. In particular, the emulation of an interlaboratory exercise, using the analytical determination of phosphorus in a dry detergent, carried out in the laboratory by different groups of students, was selected as a case of…

Research-based assessments in postsecondary chemistry education have been widely developed and published, but their use has not enjoyed the same level of focus in the chemistry education research literature as evidence-based instructional practices. Several high-quality assessment strategies have been developed for use in postsecondary chemistry…

Understanding reaction mechanisms is integral to success in organic chemistry; however, prior research suggests that learners struggle with recognizing the importance of underlying implicit features in reaction mechanisms. Because of this struggle, understanding how learners' reason about reaction mechanisms and developing assessments to elicit…

In this study, we investigated the impact of collaborative learning practices on the academic success of first generation college (FGC) students in one section of a general chemistry course. We implemented group problem solving and group quizzes during the lecture sessions of General Chemistry 1. Our focus was on understanding how FGC students…

In this study, a new competency assessment system was developed for the blended learning course "Organic Chemistry Laboratory". The system utilized a mastery transcript evaluation model and incorporated the Structure of Observed Learning Outcomes (SOLO) taxonomy and Primary Trait Analysis (PTA) scale method. With this system, students…

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…

In the field of education, ChatGPT has become a topic of debate for its usefulness as a learning tool. This article focuses on non-science majors' (n = 29) perceptions of a ChatGPT enabled final exam, where, prior to the exam, students wrote papers on science and sustainability and, during the final exam, students were asked to compare their paper…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

General chemistry II is often a challenging course for first-year STEM students, and many students rely on partial credit to achieve success in the course. However, assigning liberal partial credit to students' work can also disincentivize developing proficiency with the material. Here, we present an alternative specifications-based grading scheme…

Outreach activities have been an ongoing commitment of the American Chemical Society and other scientific organizations, yet formal assessment of outcomes has been infrequent. We have designed a simple, reliable, and robust format for assessing attitudinal and motivational characteristics of participants attending informal public events that…

The most important learning objective in green chemistry education is the ability to identify the synthesis, process, or chemical that is least environmentally harmful. Existing metrics fall short for different reasons. Mass-based metrics fail to assess environmental harm, while life cycle assessment (LCA) is much too complex to insert into the…

Chemistry students are passionate about using their learning to contribute toward a sustainable future, yet they feel unprepared to make green and sustainable practical decisions informed by industry-relevant tools. Most green chemistry metrics are mass-based, which do not estimate environmental impact or help address global socioeconomic…
