Development of Science Teaching Materials Contained with Character Education with Problem-Based Learning Model Settings to Improve Student Character and Critical Thinking Skills

Abstract

This study aims to produce science teaching materials with character education in a valid, practical, and effective problem-based learning model setting to improve students' character and critical thinking skills. The development of learning tools refers to the 4-D development model which consists of defining, designing, developing, and disseminating. The development stage is only carried out until the development stage. Data were collected by tests, questionnaires, and observation sheets, and analyzed using descriptive statistics. The results showed (1) the teaching materials were stated to be very valid with an average score of 3.84, (2) the teaching materials were declared very practical with an average score of 3.71, (3) the teaching materials were declared feasible. effective for improving critical thinking skills with a t count of 14.07 (t count > t table), (4) teaching materials are declared effective for improving student character with an increased student character development value. Based on the results of the study, it can be concluded that physics teaching materials containing character education with problem-based learning model settings meet valid, practical, and effective criteria for improving the character and critical thinking skills.
