In school, learning takes place naturally in the classroom in a traditional way. It is designed to facilitate students’ learning and teachers present information by way of spoken words and at times use teaching aids drawn on the blackboard. Researchers have faulted excessive use of the lecture method in teaching especially science subjects in secondary schools. It is believed to lead to low and under achievements among secondary school students. Jegede and Seweje (2003) corroborated this statement. They believe slow learners do not cope with lecture method. According to Resnick (2002) new technologies are changing not only what students should learn but also what they can learn. He believes many ideas and topics that have been left out of school curricula because of the limitations of traditional instructional media and delivery methods such as blackboard, paper and pencils, and boks. For instance computer simulations can be used to help students explore how systems work. In Resnick (2002) book, more entrepreneurial approach to learning has students’ divided not according to their age but students of all ages are encouraged to work together on projects thereby encouraging collaborative learning which can be of benefit to them in the labour market. This will enable them to socialise and learn from one another solving problems togther, engaging in critical thinking thereby gaining ideas that arise through such learning process. Instruction should focus on problem solving rather than the transmission of knowledge to students. The role of the teacher in the teaching and learning is apart from being a facilitator and a guide but also creating an enabling classroom environment for learning to meet the requirement of the 21
century.
