Validity and practicality of calculus teaching materials based on integrated ict contextual problems to improve students problem solving skills

Abstract

Most of the students in Calculus are not satisfactory. Some of the causes include: mathematics material has not been linked to contextual problems so that the learning process becomes less attractive, besides that students have not been able to utilize technological advancements to help understand the concepts of Calculus material, such as: graph making, derivative and integral calculations and their applications, and others other. The aim of the study was to determine the validity and practicality of Calculus Teaching Materials which are integrated ICT based contextual problems to improve students Problem Solving abilities. The research method used is R & D which is a method to produce a particular product and test the effectiveness of the product. Data collection instruments in the study included validity test sheets, practicality test sheets. The data analysis technique used is descriptive statistical analysis. The results of the study are the creation of an ICT-based calculus teaching material that integrates contextual problems to improve valid and practical student problem solving skills.
