Abstract

The purpose of this research is to develop the ability to solve mathematical problems on Trigonometric Functions Identities using Inquiry-Based Learning (5E) concept combined with the Trigonometry Hexagon technique for grade 11 students of Suan Sunandha Rajabhat University Demonstration School (Secondary Department) in the second semester of the academic year 2022, one room with 20 students acquired by co-operation. The tools used in this research were the learning management plan for Trigonometry Hexagon combined with Inquiry-Based Learning (5E) concept, a mathematics learning achievement test, and a mathematical problem-solving ability test. Statistical analysis of data using percentage, mean, and standard deviation. and the sampling t-test were independent of each other.
The research results showed the ability to solve mathematics problems after receiving the learning management using Trigonometry Hexagon technique together with the Inquiry-Based Learning (5E) concept, higher than 70 percent of the test score was statistically significant at the .05 level, which was in line with the hypothesis of this research.
