Abstract

This study aims to (1) identify the quality of STEM-based CONINCON learning on the mathematical connection abilities, (2) describe the mathematical connection ability of class XI students in terms of self-confidence in the line material in STEM-based CONINCON learning. This research used a mixed method with a sequential explanatory design. In this study there are three categories self-confidence, that is high as many as 5 people, medium as many as 24 people, and low as many as 7 people. The results showed that the STEM-based CONINCON learning model was in the good category. Student with self confidence students who have high mathematical connection skills are able to master three of the four indicators, while in one other component students are able to relate and only have obstacles that are less precise in calculating the final results.Students with moderate self-confidence are able to master two indicators, namely the indicator connections between one topic and another in mathematics, and indicator connection of mathematics with everyday life.Students with low self-confidence are able to master one mathematical connection indicator, namely the indicator connection of mathematics with everyday life, while in other indicators students have not been able to meet the indicators of mathematical connection well
