Abstract
The background of this research is the low problem solving ability among students. This study aims to analyze the problem solving ability of students who receive learning with a collaborative Learning Oriented Project Based Learning (PjBL) and Learning cycle Model with animated video. The sampling technique used was using Pre-experimental Design (Nondesign) in the form of a one-group pre-test-post-test design. The instrument used in the form of a problem solving ability test instrument that has been validated in fulfilling the content validity and reliability requirements with a high level reliability. The results obtained from the average value of the Normalized gain was high categories on both learning models applied. Based on the results of the analysis of the hypothesis test (one sample t - test) obtained tcount>ttable. which states that the problem solving ability of students who are taught using the project based learning (pjbl) learning model and learning cycle oriented to collaborative learning with animated video media on chemistry material meets the high criteria.The results showed that the problem solving ability of students for the aspect of understanding the problem was obtained by 88%, the aspect of planning a settlement was obtained by 83%, the aspect of carrying out a settlement plan was obtained by 79% and the aspect of re-examining was obtained by 74%. So it can be concluded that the aspect of problem solving ability that is developed is the aspect of understanding the problem.
