Experiencing problems that challenges science and the thought, habits of mind and actions associated with trying to solve them is one of the best ways of learning Chemistry. This impels opportunities for authentic, inquiry based learning. PBL (problem based learning) is a student centered pedagogy in which students learn about a subject through the experience of problem solving. The goals of PBL are to help the students develop flexible knowledge, effective problem solving skills, self-directed learning, effective collaborative skills and intrinsic motivation. CAPBL (computer assisted problem based learning) has been created to expand the boundaries of the creativity and the creativity of students beyond the four walls of the classroom. In the present study the investigator tested the effectiveness of the CAPBL material in Chemistry for enhancing thinking skills among secondary school students. The sample consisted of 100 secondary school students. The study revealed that the CAPBL material in Chemistry is effective in enhancing thinking skills such as critical thinking, creativity and problem solving. 展开更多
