The objectives of this study were 1) to analyze teachers’ input to develop Integrated Thematic Materials Based on Local Wisdom on Science subject Theme 3: Healthy Food, for Grade 5 Elementary School, 2) to find out how to prepare Integrated Thematic Materials Based on Local Wisdom for Science subject Theme 3: Healthy Food, for Grade 5 Elementary School , and 3) to reveal the effectiveness of the Integrated Thematic Materials Based on Local Wisdom on Science Subject Theme 3: Healthy Food, for Grade 5 Elementary School. This research was Research and Development (R & D) adapted from Sugiyono including ten steps. The validation of teaching materials wascarried out by proficient material experts and media experts. The results showed that the products in this development research were declared feasible and effective to be used as supporting teaching materials for grade V. The feasibility of this thematic module product was based on the validation results of material experts which obtained a total score of 73 in very good category and the results of validation by media experts which obtained a total score of 116 in very good category. The feasibility of the thematic module product was also strengthened by the results of the effectiveness test (N-Gain) on the product trial which obtained a score of 85.2968 or 85.30% in effective category for the experimental class, and the effectiveness test (N-Gain) on the trial which obtained a score of 88, 5386 or 88.54% with the effective category.

The objectives of this study were: to analyze teacher input, find out how to compile teaching materials, and to see the effectiveness of thematic integrated teaching materials based on local wisdom of science subject material theme 3: healthy food in grade 5 elementary school students. This research was conducted due to a lack of teaching materials, teachers were unable to develop teaching materials, and students’ lack of insight into local wisdom. This research uses research and development methods. The data analysis technique used descriptive qualitative and quantitative analysis techniques. Qualitative data in the form of input, criticism, and suggestions for product improvements presented in a questionnaire instrument for reviewing teaching materials. Meanwhile, quantitative data in the form of numbers obtained from product trials. The results showed that the module teaching materials were feasible and effective. The feasibility of this thematic module product is based on the results of the material expert’s validation, the total score is 73 and 116 in the very good category. The results of the effectiveness test in the product trial and test using the experimental class N-Gain value were 85.30% and 88.54% in the effective category.
