The Challenges and Value of Undergraduate Oral Exams in the Physical Chemistry Classroom: A Useful Tool in the Assessment Toolbox

The COVID-19 pandemic illuminated challenges with assessment, especially in online environments that threaten academic integrity. In the wake of the pandemic, faculty in higher education were seeking alternative assessments that meet the assessment goal(s) of their classroom. Even though the COVID-based disruptions are diminishing, higher education continues to experience ongoing upheaval related to new technology, such as ChatGPT, requiring ongoing reevaluation of our assessment practices. Upon reflecting on our assessment goals, we explored oral exams as a potentially valuable tool in the assessment toolbox in Physical Chemistry I and II courses at two institutions. In analyzing the course evaluation data at both institutions, we found consistent themes in student-perceived challenges, student-perceived value, and instructor-perceived value. Students had an overwhelmingly positive response to the oral exam experience and recommended their continued use in spite of their perceived challenges. Students found the oral exams challenging due to the stress and anxiety of verbal presentation and the depth of understanding required to answer questions verbally. In response to these challenges, students adjusted their study habits to incorporate studying in groups, verbally speaking out loud, utilizing spaced practice methods, and focusing on understanding concepts and equations instead of relying on memorization of material. Considering the challenges and required adjustment in study habits, students still overwhelmingly recommend using oral exams because they recognize the value of communication and teamwork in their future careers. In addition to student value, the instructors found value in oral assessments, despite the challenges with time commitments, validity, reliability, and fairness. We believe oral assessments in undergraduate chemistry curricula warrant further investigation as a useful tool in the assessment toolbox. © 2023 American Chemical Society and Division of Chemical Education, Inc.

Approaches to Promoting Student Engagement in Organic Chemistry Before, During, and After the COVID-19 Pandemic: Insights and Reflections

Active engagement is critical to student success in Organic Chemistry. In this paper, I trace the trajectory of student engagement in an introductory organic chemistry lecture series over the course of the COVID-19 pandemic. I detail my approach to cultivating student engagement in an online environment, evaluate the success of these approaches and discuss modifications, and recount our efforts to combat the "learned disengagement” that students exhibited upon returning to an in-person class format. Although engagement gradually dwindled over the course of online instruction, multiple interventions succeeded in maintaining a sense of classroom community in students and encouraging active participation. By building opportunities for engagement into the course structure and rewarding students who partake in class activities, I hope to once again enjoy the level of engagement that we had prior to the pandemic. © 2022 American Chemical Society and Division of Chemical Education, Inc.

How Partial Anonymity May Reduce Students' Anxiety During Remote Active Learning─A Case Study Using Clubhouse

Active learning, a common practice in higher education, has been shown to promote higher order thinking and skills. Class discussions have been chosen to be the medium to incorporate active learning in schools‘ curriculum. However, the rate of class participation could be low for certain courses. Literature has shown that the fear of negative evaluation from peers is the most common reason as to why students choose not to partake in class discussions. Anonymity via clickers or applications such as Kahoot! has shown to be useful in reducing students' anxiety and increasing class participations. However, this is not a viable method to employ if vocal discussion is required for the course. Here, partial anonymity (voice only), Speak Your Mind, was applied into an environmental chemistry course with 20 students in the National University of Singapore (NUS) to study its correlation with students‘ anxiety and class participation. Participants survey results suggested that a reason for not participating in class discussions was the fear of being judged by their peers. Remote learning was conducted due to COVID-19 and partial anonymity was obtained by a proxy application: Clubhouse. This application allowed students to partake in a podium discussion while maintaining psychological safety via partial anonymity. Participants survey responses indicated that partial anonymity reduced their anxiety (Cohen's d = 0.58) and slightly increased their self-reported class participation rate (Cohen's d = 0.21);it was noted that partial anonymity did not have much effect on their fears of being judged if they provided the wrong answer (Cohen's d = 0.11). © 2023 American Chemical Society and Division of Chemical Education, Inc.

SUCCESSES & CHALLENGES OF SUPPORTING PRODUCT DESIGN EDUCATION FOR DEAF & HARD OF HEARING LEARNERS DURING A PANDEMIC: A CASE STUDY

The impact of the COVID-19 pandemic on Higher Education has been considerable, none more so for practical/vocational subjects such as Product Design. However, consider being deaf/hard-of-hearing (D/HOH) whilst being forced to study predominantly online, with reduced practical in-person teaching opportunities, being socially distanced, and having to contend with face coverings limiting your ability to hear and lip read. The everyday challenges for D/HOH students in higher education is constantly demanding, but the global pandemic exacerbated this, presenting significant educational challenges. This paper presents a case study focused on the 2020/21 academic year whereby we examine the challenges and successes of supporting a product design student with Auditory Neuropathy Spectrum Disorder (ANSD) and permanent bilateral severe-profound hearing loss. The scope of this paper presents the learner arrangements for their product design education and highlights methods of managing the blended learning/teaching environment in combination with the use of British Sign Language (BSL) interpreters, electronic/handwritten notetakers and accompanying technologies. Numerous challenges were presented ranging from, managing rapidly developing online learning tools, adapting personal protective equipment to facilitate lip reading, managing multiple recording technologies to facilitate captioning/transcription, amongst others. The perspectives of the learner are presented, with reflections on how different session types, timetabling, delivery methods, etc., affected their day-to-day learning. Recommendations are made for improved collaboration with student support staff (i.e., BSL interpreters and electronic/handwritten note takers) and the need to implement digital technologies to facilitate the optimal blended learning and socially distanced teaching environment. © Proceedings of the 24th International Conference on Engineering and Product Design Education: Disrupt, Innovate, Regenerate and Transform, E and PDE 2022.

"The Masked Scientist": Designing a Virtual Chemical Escape Room

Chemical escape rooms (ChEsRms) are educational games in which students use their brain, chemical knowledge, intuition, and a bit of luck to solve a mystery. At the Weizmann Institute, we have developed ChEsRms that are implemented by teachers in their classes. Since the COVID-19 pandemic stopped all the educational activities that took place in physical space, we decided to design a virtual ChEsRm (VChEsRm) that is fully conducted in digital space. We describe the design principles that characterize the VChEsRm and present the students' and teachers' perceptions of the VChEsRm and how it differs from the ChEsRm. We describe "The Masked Scientist", a VChEsRm in which students must identify a scientist using their knowledge of basic topics in the chemistry syllabus: the model of the atom, radioactivity, and the periodic table. This VChEsRm has added values, a connection to history, human rights, and sustainability, as well as interesting and surprising chemical facts related to everyday life. Since it is conducted in virtual space, it could also include experiments, procedures, and materials that are dangerous and therefore forbidden in a physical ChEsRm or that could even change the course of history. Importantly, this 90 min activity includes the VChEsRm (9 puzzles) and a 45 min follow-up session that deals with the ideas behind the puzzles. It was translated from Hebrew to Arabic and English;therefore, high school and general chemistry teachers around the world can easily use the VChEsRm in their class after reading this paper by clicking on the link. © 2022 The Authors.

Harry Potter Themed Digital Escape Room for Addressing Misconceptions in Stoichiometry

Chemistry is often seen as an and content-heavy subject. Many students struggle with chemistry because they attempt to memorize the content without understanding the concepts. As a result, students often have misconceptions. COVID-19 has driven teaching and learning online, and an escape room teaching method, which is a way to enhance student engagement, has gained popularity among educators in higher education. This study examines the effectiveness of teaching through a digital escape room as compared to a typical online lesson with a collaborative learning method to address misconceptions in stoichiometry. A Harry Potter themed digital escape room is created to spark the students' interest in chemistry and address misconceptions. Thirty-eight students from the Nanyang Polytechnic Foundation Program participated in this study. The students completed a pretest, a post-test, and a survey, in addition to participating in the digital escape room and a typical online lesson. Four topics were covered in this study: balancing chemical equations, calculating empirical formulas, identifying the type of chemical bonding, and interpreting element symbols. Out of these four topics, it was discovered that students tended to have difficulty calculating empirical formulas. It was found that, on average, students showed a 10% improvement in test scores after being taught through the digital escape room. This result is similar to results obtained from a typical online lesson with a collaborative learning method (9% improvement). This implies that a digital escape room is equally as effective as a typical online lesson with a collaborative learning method at addressing misconceptions. Teaching through a digital escape room has shown potential additional benefits of enhancing soft skills, promoting teamwork, the ability to work under time pressure, communication skills, innovation competency, and increasing student motivation. The researcher recommends the use of a digital escape room to complement typical lessons for these additional benefits.

The Thalidomide Mystery: A Digital Escape Room Using Genially and WhatsApp for High School Students

This paper reports the development of a digital escape room for high school students using Genially, a web-based media platform. The escape room was used to aid understanding of basic concepts in chemistry and mostly enhance students' classes participation during the COVID-19 pandemic. The activity entitled "The thalidomide mystery" covered the concepts of chemical bonding, pH, acid and base, and laboratory glassware. The narrative of the game revolves around the drug named thalidomide;this drug was developed in the 1960s and its use caused several cases of phocomelia. WhatsApp chat groups were formed to stimulate an active engagement of the participants and maintain a collaborative and cooperative learning experience among them. Students were required to solve four chemistry puzzles to obtain the final password to reach the end of the game. The results obtained showed that the game was very useful for students mainly because it presented an innovative way of teaching chemistry, different from the traditional way in which the students are usually taught in their classrooms. The game helped the students to review the contents covered and was able to stimulate the active participation of both the students who like to study chemistry and those who do not.
