This study aims to develop the Environmental Learning Model (ELM) by using documentary videos to improve knowledge of coastal residents of Palopo City about mangrove, wastewater, domestic waste, and liveable house. There were two phases used in this research. The first phase examined the concept of the lesson plan, guidedbook, video material, evaluation tests, and answer sheets that were validated by the experts. In the second phase, two reviewers examined the practicality and the effectivity of the learning implementation. The validity result of the guided-book was in very valid category. The lesson plan was in very valid category, and the video material was also in the very valid category. This validation was carried out by educational expert and multimedia expert. Practicality: Two educational reviewers stated the syntax, social system, reactional principle, support system were implemented entirely. Effectivity: The learning result of environmental knowledge in the first trial was in the Medium category (47,5). And in the second trial, it improved to the High category (60,8).So, it can be stated that the development of learning model through documentary videos is valid, practical, and effective to be used in improving environmental knowledge for the coastal resident to avoid bad behaviour.

The purpose of this research is to develop learning media in the form of a Statistics Module with a Problem Based Learning (PBL) approach. The Statistics module uses the PBL approach, which is an approach that provides support for developing students’ skills in solving problems in statistics courses due to create enjoyable learning and make students more active than lecturers in the class, not lecturer center anymore. The results of the research conducted in this study are PBL-based statistics course modules (mean, median, and mode) which in the future will be used by students of the Informatics Management Study Program – Academy of Computer Sciences Ternate. The advantage of the PBL-based Statistics module that is used as teaching material is that it makes it easier for students to solve problems in statistics courses and make them more interested in learning them. The PBL-based statistical learning module used as a learning medium can be declared feasible to use based on the results of expert validation and the results of small group module trials. Expert validation is carried out by 2 (two) experts with very appropriate, appropriate, adequate, or inadequate assessment categories. All experts (both) assess if 100% of the module is included in the very feasible category. Whereas for small-scale field trials, 75% of respondents stated that the module was in the very feasible category and 25% of respondents said the module was in the feasible category.
