Although these two strategies did not exhibit as large an effect as did the strategies of focusing and questioning, there was some positive support for inquiry teaching. Figure 1 shows the system. Laboratory Teaching Methods This methods is one of the important methods of teaching science and it forms an integral part of effective science teaching. This development has generated discussion about the fundamental learning outcomes of laboratory training courses and, ultimately, an interest in the consequent changes to the students learning experiences. One of the students commented that I dont know what is going on in the virtual workshop training at all. There was also one student who did not want to participate in traditional laboratories, as he was a computer science student who believed that he did not need traditional EEE laboratory training for his career.

"I feel the games have helped me a great deal as they enabled me to see the theory in action and made it more memorable", "Sometimes I find certain theories or concepts very difficult to understand properly when being taught in a normal lecture. As McKeachie pointed out, laboratory teaching may not be the best method to choose if one's objective is to have students retain information. PDF METHODS OF TEACHING SCIENCE - DDCE, Utkal Godomsky (1971) reported that laboratory instruction increased students' problem-solving ability in physical chemistry and that the laboratory could be a valuable instructional technique in chemistry if experiments were genuine problems without explicit directions. 2- Virtual labs help teachers and students save time and effort because they dont need to adhere to certain times to enter the lab, or to move from one place to another.
