摘要：AbstractThe recent budget cuts in Universities in Malaysia affect the running of practical chemistry classes at undergraduate levels as purchase of equipment, glassware, chemicals and other consumables need to be reduced. The rising costs of chemicals also alleviate the problems in the acquisition of sufficient chemicals for the practical classes. Most lecturers give priority to equip their research laboratories as expected when Universiti Kebangsaan Malaysia was given the status of a research university by the Government of Malaysia. With such challenges, it is inevitable that the teaching of practical chemistry in the undergraduate are given less attention and the quality deteriorating since experiments are done by a group of 4 students as a measure to adjust to the availability of equipment and chemicals in the laboratory. Another necessary measure is to reduce the number of experiments conducted by the students. For organic chemistry practical classes, the small lab kit provided a solution for practices to run as usual and the learning of organic chemistry more effective. Students per group can be downsized to two per group to encourage everyone to be hands-on. The quality of learning can be enhanced and the quantity of chemicals can be reduced 10 times or even lower in some experiments. The students’ awareness to the conservation of environment can be manifested through the savings in the use of chemicals and water. Survey conducted among second year organic chemistry students showed that 80% of the students agreed that using the portable chemistry laboratory kit has enhanced their interest in learning chemistry. Among the reasons given is that the time taken to set up the experiments as well as conduct the experiments are short compared to the traditional methods. Experiments can be repeated easily. The types of experiments using common materials from daily life need to be developed to attract interest among students to learn chemistry.
