Improving Teaching Quality and Problem Solving Ability Through Contextual Teaching and Learning in Differential Equations: A Lesson Study Approach

Abstract

Differential equations is a branch of mathematics which is closely related to mathematical modeling that arises in real-world problems. Problem solving ability is an essential component to solve contextual problem of differential equations properly. The purposes of this study are to describe contextual teaching and learning (CTL) model in differential equations course, to improve lecturers’ abilities in implementing CTL, and to improve students’ problem solving ability in differential equations. The study was conducted in the fifth semester of 2015/2016 academic year with 34 students of mathematics education Universitas Muhammadiyah Surakarta as participants. The CTL model was applied by lesson study approach which involved three stages namely plan, do, and see in each cycle. This research was conducted in four cycles. The study results found that discovery-based CTL could be applied in differential equations course. The lecturer abilities to design discovery-based contextual learning plan, to present real-world problem in learning process, to design learning strategy and assessment instruments of problem solving improved significantly. Problem solving ability of students also improved during teaching and learning process.

The Effect of Contextual Teaching and Learning (CTL) Based on Lesson Study on the Biology Learning Achievement of High School Students

“…Contextual Teaching and Learning based on Lesson Study can help students be more active and also help teachers in the process of designing a learning that is appropriate for students. Contextual Teaching and Learning model based on Lesson Study can be well received by students, shown through a positive response in the application of learning models and the learning atmosphere noted to be dynamic (Khotimah, 2016). Contextual Teaching and Learning model based on Lesson Study can also help students become easier in understanding the learning indicated by the increased learning outcomes in the cognitive domain (Fadillah et al, 2017).…”

“…Boyce & DiPrima (2001), states that DE is an equation in which there are one or several derivatives. DE is one of the advanced mathematical concepts that are widely used in applied mathematics applied in the fields of physics, chemistry, biology, engineering, social and psychology (Boyce & DiPrima, 2001;Machin, Diaz, & Trigo, 2012;Khotimah & Masduki, 2016 ;Vajravelu, 2018).…”

“…The contextual approach is a strategy that emphasizes the involvement of students in finding their own material or concepts learned and connecting them in real-world situations [11]. The contextual approach is a strategy in learning that has seven principles or components, they are: Constructivism, Inquiry, Questioning, Learning Community, Modeling, Reflection, and Authentic Assessment [12].…”
