The effectiveness of outdoor learning-based teaching materials for middle school students

One of the innovations that can be developed based on the problem of the learning angle created is a learning resource based on outdoor learning as an alternative learning media for students. This study aimed to determine the effectiveness of the use of PjBL Teaching Materials with Ethnomathematics Based Outdoor Learning. The sample consisted of 34 students from class VIII D with one group pre-test-post-test design. The results showed that the designed teaching materials were feasible to use. First, the data shows an N-gain coefficient, which indicates the effectiveness of teaching materials on students' mathematical communication. Other data collection shows that students understand the content of teaching materials. In conclusion, this teaching material makes students not only aware of the Pythagorean theorem material but also gives them a different learning atmosphere so that the material is imprinted more deeply in their memory.
