Although previous studies have confirmed the various benefits of concept maps, limited information is available regarding how to effectively employ the concept map in online courses. In this research, we have designed and assessed the effectiveness of the "Zoom-sandwiched cross-chapter concept map" model in an online biology course. The…

The purpose of the presented article is to evaluate the students' perception of the online teaching educational model as a part of the "Biochemistry with Elements of Chemistry" course conducted during the COVID-19 pandemic at the Faculty of Medicine of the Jagiellonian University Medical College. The first part of the article reflects…

Background: Collaborative computer simulations are available on some online platforms which support students at distributed locations to synchronously collaborate on the simulations to learn sciences. However, how students collaborate with each other in collaborative simulations is not clear. Objectives: The aim of this study was to investigate…

The forced move to online learning in the arrival and persistence of the COVID-19 pandemic underscored the present lack of models for fully online general chemistry laboratory courses. While there exist a fair number of simulation platforms, video libraries, and one-off virtual experiments, a lack of complete general chemistry lab online courses…

Beginning in March 2020, instructors and students in educational institutions across the world have had to adapt to new virtual methods of teaching and learning. This study focused on obtaining the student perspective of remote chemistry lecture delivery methods across 13 Fall 2020 courses with students in varied majors of study and stages of…

The COVID-19 pandemic forced higher-education institutions to close campuses and pivot all face-to-face (F2F) instruction online. This transition to Crisis Distance Education (CDE) was unprecedented in scope and speed as it was implemented globally. We surveyed students in a large, introductory-level biology course to understand their opinions…

On March 19, 2020, Argentina's government decided to close academic institutions for an indefinite time in an attempt to contain the spread of the COVID-19 pandemic. Since the University established that, when the quarantine ends, 5 weeks will be reserved for face-to-face activities that could not be carried out virtually (laboratory lessons and…

Within two sections of science methods for elementary and middle-school teachers, an embedded, multi-case study design was employed to explore whether teaching rehearsals would better prepare preservice teachers (PSTs) to implement explanation-driven science instruction. A teaching rehearsal allows PSTs to practice teaching a segment of their…

The transition to online learning in spring 2020 was abrupt for both students and instructors. While many instructors moved to asynchronous classes, some institutions relied more heavily on synchronous online courses. Here, we evaluate student perceptions of an inquiry-based molecular biology lecture and lab course following this transition by…

To investigate how physics students perceived the sudden shift to online learning at the beginning of COVID-19 pandemic, 18 semistructured interviews were conducted with university students in Austria, Croatia, and Germany. Based on the interviews, a questionnaire was developed and data from N ¼ 578 physics students from five universities in…

This mixed-method study introduced an adaptive scaffolding system to support middle school science problem-based learning (PBL) activities. 298 6th-graders were grouped into three conditions, which are the adaptive scaffolding group, the non-adaptive scaffolding group, and a control group that did not receive any scaffoldings. Results showed that…

As instructors return to in-person teaching and learning following online teaching during the COVID-19 pandemic, we can build from the experiences gained and incorporate various online resources into our campus-based classes. Drawing from student evaluations of teaching, a post-course student survey and learning management system (LMS) analytics,…

This study compares synchronous versus asynchronous online teaching in an introductory calculus-based physics class. Like many schools, our institution transitioned to online teaching during the COVID-19 pandemic. We held optional synchronous online sessions during the original class time, and approximately half of our students were regular…

The COVID-19 outbreak spurred unplanned closures and transitions to online classes. Physical environments that once fostered social interaction and community were rendered inactive. We conducted interviews and administered surveys to examine undergraduate STEM students' feelings of belonging and engagement while in physical isolation, and…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…
