The Sudden Switch to Online Teaching of an Upper-Level Experimental Physical Chemistry Course: Challenges and Solutions

Abstract

This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required modifications in order to reduce the educational losses. The use of videos, icebreakers, homework, prelab quizzes, in-lab questions, and synchronous meetings helped to keep the students engaged and maximize the achievement of learning goals. The technology challenge when internet connections were poor was swiftly addressed by the students switching to cell phone data plans. Academic integrity was managed through the use of an open-book exam using original problems that required critical thinking and problem-solving skills rather than only regurgitation of knowledge that could be copied from textbooks or found online. Although gains were obtained through writing lab reports, solving the homework, prelab quizzes, and in-lab questions as well as generating questions about the laboratory experiments, the development of problem solving skills to address challenges during the actual instrument operation and planning and conducting an authentic research experiment were lost because instruction was not face-to-face.

LAB Theory, HLAB Pedagogy, and Review of Laboratory Learning in Chemistry during the COVID-19 Pandemic

Design of Network-Assisted Teaching of Ideological and Political Courses for College Students Based on Android System

“…Therefore, it is of great significance to improve the ideological and political education level of college students. In the teaching process, teachers can improve students' ideological and political con-sciousness through reasonable arrangement of students' extracurricular time, which can effectively cultivate the thinking logic and value level of college students [5]. With the rapid development of the Internet, online teaching has gradually penetrated into the ideological and political curriculum system of universities.…”
