Abstract

The aim of this thesis was to suggest a flexible way of using simulation programs and computer-controlled instruments in order to improve the chemistry laboratory training without increase the laboratory cost. Specifically, we studied how to interface old models of chemical instruments with old computer models using an Analog to Digital/Digital to Analog Converter in order to decrease the cost of laboratory equipment and to give students a hand-on experience in obtaining and handling results automatically using a PC. We investigated how to design and develop educational software (simulators) and to integrate them into chemical laboratory education in order to overcome the difficulties of time, cost, number of students and the connection of theory with experimental procedure. The simulation programs, which we have developed, were about viscosity experiments, UV-Visible spectrophotometer, pH-meter and the calibration of a NTC Thermistor. Furthermore, we studied the impact of three-dimensional (3D) applications on chemistry education. This part of research was held in the Centre for Virtual Reality of Salford University (UK) (supervisor Academic Director/Reader David Roberts). The teachers had the opportunity to create a stimulating and motivating teaching environment where learning can be both challenging and pleasurable. The students had the opportunity a) to discuss the experimental design, and analysis of experimental data with the teacher, b) to connect the new knowledge with their previous knowledge, c) to collaborate all together and d) to acquire computer experience.
