The COVID-19 outbreak has altered chemistry laboratory instruction and forced us to reconsider the balance between face-to-face and online teaching. Our students preferred face-to-face teaching (score 4.1/5 on a Likert-like scale) to virtual laboratory exercises (3.4/5) despite the fact that their performance score was actually lower in…

This paper reports on a case study of an immersive and integrated multi-instructional approach (namely computer-based model introduction and connection with content; facilitation of individual student exploration guided by exploratory worksheet; use of associated differentiated labs and use of model-based assessments) in the implementation of…

To explore the potential of computer controlled videodiscs for simulating undergraduate science laboratory instruction, the Annenberg/CPB (Corporation for Public Broadcasting) Project funded the University of Nebraska to create and field test six videodisc laboratory experiments, two each in biology, chemistry, and physics. The six discs were…

The high percentage of students who have difficulty in solving free-response problems related to the mole concept was addressed by implementation of reading skill strategies and computer assisted instruction. Frayer models, semantic mapping, and graphic organizers from Reading in the Content Area (RICA) were used to increase student understanding…

In recognition that computers are becoming an integral part of science teaching, the British Department of Education asked the Royal Society of Chemistry to investigate the current use of microcomputers and microelectronics in teaching chemistry at the secondary school level. This document presents the results of that study. It includes: (1) an…

The concept of the density of a material has an important role in elementary and secondary school science curricula, but it is a difficult concept to grasp. This project explores why this should be and whether there are some simpler, more accessible notions which can serve as the basis for building a concept of density in students' minds during…

Technological tools, which meet the needs of the society, have become more addictive for people with the rapid development of technology. These tools have also been used in the field of education and improved through the Internet where there is continuous information exchange. Educators needed the attitudes of the students towards technological…
