Discovery Lab in the Chemistry Lecture Room: Design and Evaluation of Audio-Visual Constructivist Methodology of Teaching Descriptive Inorganic Chemistry.
Young, Barbara N.; Hoffman, Lyubov
Demonstration of chemical reactions is a tool used in the teaching of inorganic descriptive chemistry to enable students to understand the fundamental concepts of chemistry through the use of concrete examples. For maximum benefit, students need to learn through discovery to observe, interpret, hypothesize, and draw conclusions; however, chemical discovery labs are time consuming to prepare and present and may involve hazards. The purpose of this study was to design an effective audio-visual method for teaching descriptive inorganic chemistry and to investigate whether an audio-visual method could be a viable alternative to the live demonstration method. Data were collected for quantitative and qualitative analysis. Quantitative analysis indicated that the audio-visual method does not account for a statistically significant proportion of variance in students' achievement scores. Qualitative analysis of data indicated that there was an equal preference of students for each method. Students favored either method of presentation (audio-visual or live demonstration) over the traditional lecture method. It was concluded that audio-visual discovery lab experiments can be used in teaching descriptive inorganic chemistry, but further research needs to be done to improve the quality and methodological design of audio-visual presentations.
