Abstract

This study aims to: 1) Determine the significant differences in students’ mathematical abilities using the Problem-Based Learning (PBL) and Expository learning model with Online-based learning; 2) Knowing the difference in the significant increase in students' mathematical abilities using the PBL and Expository learning model with online-based learning. The research method used is a Quasi Experiment with Nonequivalent Control Group Design. The research subjects were students of class XI MIA which consisted of 33 students in the experimental class and 35 students in the control class. The results showed that all stages of learning were in accordance with the stages of the PBL and Expository learning model. Based on statistical calculations (t-test ') with a significance level of 0.05, it was found that there was no significant difference and increase in the mathematical abilities of students who were taught the PBL and Expository learning model with Online-based learning.

Abstract

This study aims to develop Problem Based Learning (PBL)-based worksheets to improve student’s critical thinking skills in contextual problem solving. The research design used is a feasibility analysis by research and development methods. The research was carried out using research and development (R&D) research and development methods. The sample consisted of 40 students from science programs in 11th grade. The data collection instrument used is the expert assessment sheet, student responses to the created worksheet. The development procedure with 8 stages namely potentials and problems, information gathering, product design, expert validation, first revision, product trial, second revision, final product. From the results obtained the average feasibility value by the media is 81.46% (very feasible), the average graphic feasibility value is 81.85% included in the very feasible criteria, the language eligibility average value is 76% included in the appropriate criteria and the average value of student responses is (87.40%) (very positive).
