This study aims to enhance inventive abilities for secondary students by using the Invention Learning Approach. Its activities focus on creating new inventions based on the students' interests by using constructional tools. The participants were twenty secondary students who took an elective science course that provided instructional units integrated with the Invention Learning Approach for 40 h, over a period of 20 weeks. A mixed-method approach was used to investigate and analyze the data. The results of this study indicated a significant increase in their inventive abilities. The qualitative data reported that students benefited from learning by this approach. Findings of this study can be used to determine how innovation and creativity can be fostered through the Invention Learning Approach teaching students how to be more innovative while solving real world problems.
