<p>This study aims to obtain an overview of improving students' critical thinking skills and communication skills whose learning activities use integrated blended learning of local wisdom. Learning activities are carried out by modifying blended learning stages, namely at the seeking information stage. The research subjects were 109 students of the 2<sup>nd</sup> semester of science education study program. The research was conducted using a quasi-experimental method with a pretest-posttest design. The instrument used was a multiple-choice test using an assessment rubric and an observation sheet. The research data were analyzed using multivariate analysis. The results showed that the improvement of students' critical thinking and communication skills with blended learning (treatment class) was more significant than students whose blended learning was not integrated with local wisdom.</p><p><strong> </strong></p><p><strong>Keywords</strong>: blended learning, local wisdom, critical thinking skills, communication skills</p>

The Difference

Critical thinking skills are included in the ten skills needed in the era of the industrial revolution 4.0. Students are trained to be able to analyze problems and find solutions from various sources. To enhance the critical thinking skills of students, activities that can be developed are needed, namely through authentic learning, one of which is designing an eco-brick social campaign to overcome plastic waste. Authentic learning activities are in the form of real-world relevance, multiple sources and perspectives, collaboration, reflection, ill-defined problems, and sustained investigation. The quasi-experimental method was used in this study, with the research subjects being 62 students in one of the East Jakarta Junior High Schools in grades 7F and 7H. The data analysis technique in this study was to analyse the results of validity, normality, homogeneity, and independent t-test using SPSS 20 as a statistical tool. According to the research results, it was found that the difference in the average critical thinking ability between groups of students, experiment class with authentic learning treatment revealed 80.73% and control class showed 70.37%. A large number of students have difficulty in critical thinking, namely in the aspect of explaining reasons. Meanwhile, in designing eco-brick social campaigns, the experimental class is in a pretty good category, so it can be revealed that students can build critical thinking skills in solving problems through authentic learning to design eco-brick social campaigns and it is suggested that the different contents in the form of authentic learning in creating social campaigns can be developed.
