Cognitive Pre-Test & Post-Test Instrument

This dataset contains a cognitive pre-test and post-test instrument designed to assess students' knowledge of Occupational Safety and Health (OSH) in agricultural vocational education. The instrument consists of 20 multiple-choice questions covering fundamental OSH concepts, including workplace hazards, risk assessment, personal protective equipment (PPE), occupational diseases, ergonomics, standard operating procedures (SOP), first aid, and workplace safety culture. The file also includes the answer key, students' pre-test and post-test scores, normalized gain (N-gain) results, completion status, and descriptive statistics. This instrument was developed to evaluate the effectiveness of Occupational Safety-Integrated Project-Based Learning (PjBL) in improving students' cognitive learning outcomes.
