VISUAL COMMUNICATION TECHNIQUE TO ENHANCE TEACHING AND LEARNING PROCESSES IN QUANTITATIVE ANALYSIS AND INSTRUMENTATION COURSE

Abstract

Visual communication has become an important technique for the 21st century’s education. Images and videos are essential tools for better understanding in science and technology subjects. The science and technology subjects can be better understood through a combination of visual communication and application of the theory can be practiced. 40 students from quantitative analysis and instrumentation course were given an assignment using the separation concept. Only two students were unable to perform the task well and these students were also among the students who failed to answer the examination questions involving the application of separation techniques. Correlation tests between assignment and examination scores (involving separation concept questions) showed a positive correlation (r= 61.1). Despite the small number of respondents, the results showed a relatively strong correlation. To address this issue, students were encouraged to share their video among them, so that they can understand the separation techniques excellently.
