Development of Knowledge Building Environment (KBE) - based colloidal system learning materials to develop student’s environmental literacy: An environmental analysis

This study aims to develop a knowledge building environment (KBE)-based colloidal system learning material to develop students’ environmental literacy. To realize this, the problem questions raised in this study are: “1) What are the product characteristics of colloidal system teaching materials based on knowledge building environment to develop student environmental literacy which is developed with the 4STMD method? 2) What is the understanding aspect of colloidal system teaching materials based on knowledge building environment to develop student environmental literacy which is developed with the 4STMD method? and 3) How is the feasibility of colloidal system teaching materials based on knowledge building environment to develop student environmental literacy which is developed with the 4STMD method? The research method used is Development Research (DR) with a book development model using 4STMD. The results of the study show: 1) Characteristics of teaching materials developed are very in accordance with the following criteria: curriculum, scientific correctness, containing KBE values and environmental literacy, equipped with concept maps, structured and systematic; 2) Understanding of teaching materials by students is high (88.21%); and 3) The feasibility of teaching materials amounting to 96.81% (very feasible) fulfilling the criteria for the assessment of lesson text books based on BSNP standards means that they are worthy of use.
