Teaching materials used by teachers in acid-base material have not been able to develop students' critical thinking skills. One solution that can be done to develop students' critical thinking skills is using acid-base module’s based on REACT (Relating, Experiencing, Applying, Cooperating, and Transferring). The aim of this research is to produce an acid base module based on REACT and reveal its validity and practicality. The type of research used is Research and Development (R&D) using the 4-D model. The module design has been assessed by seven validators who are Subject Matter Experts (SMEs) consisting of chemistry lecturers from FMIPA UNP and chemistry teachers. While the practicality test was conducted by 3 chemistry teachers and 26 students of class XI MIPA SMAN 1 Padang Panjang. Data analysis techniques in this study used the Content Validity Ratio (CVR) and Cohen's kappa formula. The module design produces three main characteristics, namely: the module is designed in accordance with the prior knowledge of students; the module contains the REACT syntax component; and the module contains aspects of critical thinking skills developed by Ennis. The results of the content validity obtained value of the Content Validity Index (CVI) of 0.90 with a valid category and the results of the construct validity obtained kappa moment of 0.92 with a very high validity category. While the module practicality results according to the teacher and students obtained a kappa moment of 0.86 with a very high practicality category. The conclusion from this study is that the module developed is valid and practical.

PjBL and STEM learning models can overcome the lack of critical thinking skills and collaboration. Those learning models involve 4C that support students’ critical thinking skills and collaboration. This study aimed to identify the effectiveness of STEM-based PJBL models on students’ critical thinking skills and collaborative attitudes. This study was quantitative research with a descriptive method. The data had been collected using a critical thinking skills test, collaborative attitude questionnaires, and learning observation guidelines. Before performing data analysis, the researchers performed prerequisite tests consisting of the normality test, homogeneity test, variance-covariance matrix homogeneity test, N-Gain test, and effectiveness test. The basic assumption test results showed that the MANOVA test could be performed. The MANOVA test results revealed that the STEM-based PjBL learning model effectively improved students' critical thinking skills and collaborative attitudes.
