The document discusses the role of heuristic method in science classes. It notes that the heuristic method allows students to discover knowledge through experiments rather than lectures. Students struggle with concepts like researchers. This practical, hands-on learning helps develop scientific attitudes and research skills. The study aims to understand the effectiveness of the heuristic method compared to traditional lecture-based methods. A questionnaire was used to collect data from 20 students on their experiences learning science through different methods like experiments, lectures, textbooks and role-plays. The findings suggest most students prefer learning by doing experiments, which provide permanent and lasting knowledge compared to lectures or textbooks. The heuristic method helps develop curiosity, scientific attitudes, and research skills in a challenging way.
