The purpose of this study was to determine the validity of the teaching materials of the Chemistry Science Study (CSS) course using cooperative learning models on “Stereochemistry” matter. The data collection technique used research instruments, namely the validated teaching material validation sheet. Data were analyzed using quantitative methods and their results were expressed in qualitative narrative. Validation analysis toward the research instruments for each teaching material of SLP, SB, SW, QST, and CMT gave total avarages was 3.88; 4.00; 3.94; 3.88; and 4.00 with very valid category. Meanwhile, the validation analysis of the teaching materials each gave an assessment aspect with a total avarage for SLP-01, SLP-02, and SLP-03 which are 3.95; 3.95; and 3.95 with very valid categories. Then, the total average for SB is 3.84; then for SW-01,-02, and-03 are 3.95; 3.70; and 3.70 with very valid categories, respectively. Validation analysis for CMT obtained a total average of 3.88 with very valid criteria. Finally, the results of the feasibility test of SB both in terms of content feasibility and presentation feasibility obtained a total average of 3.77 with a very valid category. Thus, as a whole, the teaching materials of CSS is stated to be very valid and ready to be tested for practicality and effectiveness of the teaching materials in the next learning process. © 2018, Beijing Science Education Innovation center.
