A Study on Flipped Classroom based on Donald and Maki’s Approach for Developing Mathematical Connection in Exponential and Logarithmic Functions to Real-Life Situ-ations for Grade 10 Students.

The objective of this research is to develop real-life mathematical connection ability in exponential and logarithmic functions. The population used for this research was two classrooms of grade 10 students, semester 2 in the 2020 academic year of Suksanari School, with 77 students. The researcher used the cluster random sampling method to select a sample of one classroom of 31 students. The research instruments include pre-test and post-test for real-life mathematical connection ability and eight "Flipped Classroom" lesson plans based on Donald and Maki's approach (consist of six steps; Revisit, Real World, Real Model, Classroom Model, Mathematical Model, and Conclusion.) The results of the instrument quality test showed that the reliability of the pre-test and post-test for real-life mathematical connection ability from five experts with the Alpha Cronbach coefficient was 0.84, a difficulty levels of 0.36 to 0.68, a discrimination power value was from 0.23 to 0.50, and content validity score of 0.95. The statistics used to analyze the data were reliability, content validity, and relative gain score. Furthermore, we analyze the report after implementation of each lesson plan for showing their mathematical connection abilities as the qualitative data. The results revealed that all students had improved the mathematical connection ability to real-life.
