Abstract: At present the environmental problems concerning with the management of solid wastes and wastewater both locally and nationally, in part resulting from people’s lack of suitable learning resources for the management of solid wastes and wastewater. Therefore, the researcher was interested in developing the learning resources for the management of solid wastes and wastewater from communities. The purposes of this study were: to develop an effective learning resource for the management of solid wastes and wastewater from communities, to develop training plans for management of solid wastes and wastewater through the learning resource, to compare the knowledge and attitudes toward the management of solid wastes and wastewater from communities before and after the training and to compare the knowledge and attitudes toward the management of solid wastes and wastewater from communities of the second-year students with different sexes and courses of study at Ubonratchathani Rajabhat University. The sample consisted of the 80 2nd year students: 40 male students and 40 female students; 20 students each, majoring in B.Ed., B.A., BB.A. and B.Sc. degree courses. The t-test and the F-test (Two-way MANCOVA) were employed for testing hypotheses. The findings of the study were as follows: Firstly, the developed learning resources model for the management of solid wastes and wastewater emphasized, simplicity, economy, convenience and practical uses. The appropriateness of the learning resources was at the more level as evaluated by the experts and visitors. Secondly, the training model was at the most appropriate level as assessed by the experts. Also, materials and handbooks on training of management of solid wastes and wastewater were at the most appropriate level. Thirdly, the students as a whole and as classified by sexes and courses of study showed gains in knowledge and attitudes toward management of solid wastes and wastewater in general and in two subscales: solid wastes management and wastewater management, from before training at the 0.01 level of significance. The students with different degree courses indicate only the knowledge of management of solid wastes and wastewater (p<0.017). In summary, the developed learning resources for management of solid wastes and wastewater from community was appropriately effective for being as part of training, which could increase students’ knowledge and attitudes toward solid wastes and wastewater management. Involved persons should be encouraged and supported to implement this learning resources of solid wastes and wastewater management for other students and groups of people.
