Calculus Learning with Problem-solving Learning Based on Blended Learning Approach

This study aims to develop calculus learning tools for problem-solving models based on blended learning approaches that meet valid, practical and effective criteria. Learning tools in the form of semester learning plans, learning program units, modules, and student worksheets that aim to improve students' creative thinking skills and learning independence. The development method uses the Borg & Gall development model which consists of Research and information collecting; Planning; Develop a preliminary form of product; Preliminary field testing; Main product revision; Main field testing; Operational product revision. The product of development was tested on students of the Mathematics Education Study Program at the Musamus University 2019/2020 academic year. The results were obtained that the-learning tools with the blended learning-based problem-Solving model met the highly valid criteria for RPS and SAP, valid criteria for student modules, and worksheets based on validator ratings. While the assessment instruments in the form of questions about the ability to think creatively and independence questionnaires meet very valid criteria. The device was tested on 8 Mathematics Education study program students. The results of the the practicality assessment by students and based on observations of the implementation of learning obtained the conclusion that the-learning device meets practical criteria. Based on the test results obtained that the mathematics learning device with the Problem-solving model based on blended learning in effective calculus lectures increases the creative thinking ability that is 75% Students have the ability to think creatively in the minimal category sufficiently, while in the aspect of learning independence it is obtained that the-learning device is not effective in increasing learning independence only 69.4% of students in the high minimum category.
