Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…

Active learning provides students with meaningful and introspective roles in education. However, active learning is difficult to achieve in online class settings, particularly for biology laboratories initially designed to offer direct interactions with live organisms. During the COVID-19 pandemic, a transition to online learning was required in…

During COVID-19 remote instruction, instructors were tasked with providing students with authentic laboratory experiences in an out-of-classroom environment. One solution developed for our introductory general chemistry laboratory involved students critiquing readily available technique videos to distinguish between correct and incorrect…

Online video experiments are a promising educational technology tool for science laboratory classes. In order to find optimal instructional designs and scenarios for using online video experiments, we need to study learners' experiences. This work describes implementation of an online interactive video experiment at the undergraduate introductory…

The unforeseen COVID-19 pandemic forced educational institutions to shift to a remote or distance-learning mode. As a result, classes were offered online, and this shift in teaching modality presented great challenges, especially in teaching laboratory courses. While several options are available, we evaluated the use of (i) videos of lab…

Laboratory classes form an important aspect of bioscience education. However, this environment is challenging for students due to cognitive load and lack of confidence. Familiarising students with aspects of their laboratory classes prior to the session can improve this. This study compares the pre-laboratory scaffolding that bioscience and…

Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

Students were tasked with the creation of videos of ordinary reactions to promote significant learning of complex concepts underlying chemical transformations. Interactive infographics were used to deliver instructions. Afterward, students planned the experimental setup for the reaction execution and video recording using their mobile phones. The…

The limited capabilities of teaching laboratories, combined with an increasing number of students enrolled in university, require constant augmentation of instructional approaches. By enhancing laboratory demonstrations with digital technology, these structural issues can be addressed while at the same time enhancing student understanding and…

A remote laboratory that measures the enthalpy of vaporization ([delta]"H"[subscript vap]°) and the entropy of vaporization ([delta]"S"[subscript vap]°) of "n"-octane was designed, constructed, and offered to second-year physical chemistry undergraduates at the University of New England (UNE) and Curtin University.…

Current research suggests that students often fail to focus equally on the three aspects of scientific argumentation (cognitive, epistemic, and social) when they are given an opportunity to engage in argumentation. This study examined student argumentation within a two-semester general chemistry laboratory sequence at East Carolina University to…

Beginning abruptly in the second half of the Spring 2020 semester at Purdue University, we modified our teaching approach in Introductory Soil Science and Forest Soils courses (AGRY 255/270) with a combined annual enrollment of [approximately]370 students to cope with the COVID-19 pandemic. In that semester, we went to entirely virtual lecture,…

After the COVID-19 pandemic, there was an increasing demand for remote learning and an expansion in the substitution of traditional practical sessions with lab-based virtual tools. This study aimed to assess the effectiveness of virtual labs in practicing biochemical experiments and to examine the student's feedback regarding this tool. Virtual…

The COVID-19 pandemic presented many challenges for educators. In Course-based Undergraduate Research Experiences (CUREs), where students learn about the scientific process by working on novel research, few resources for remote learning were available. Here the impact of changes to course delivery format on student learning gains in a…

The COVID-19 pandemic has emphasized the importance of designing effective methods for remote teaching. At the University of California, Berkeley, and the University of California, Santa Cruz, instructors adapted to the necessity of remote laboratory instruction by creating choose-your-own-adventure-style video-based online experiments introduced…
