Developing Model-Eliciting Activities with the ASSURE Model
This research aims to develop a mathematics learning tool using model-eliciting activities with problem cards to build the self-confidence of junior high school students in Indonesia. It implements the ASSURE method, which comprises the following six steps: Analyze Learners; State Objectives; Select Methods, Media, and Materials; Utilize Materials; Require Learner Participation; and Evaluate and Revise. The assessment was provided by experts in learning materials, learning tools, and learning media, with all indicating positive feedback. Respectively, the scores were 88%, 91.2%, and 80%, leading to the conclusion that this tool is valid and proper. Other findings of this study show that the average learning that resulted from the experimental class was better than that of the control class. The learners in the experimental class achieved an average score of 82.9, substantially higher than the minimum mastery criteria of 70. In contrast, the average score for the control class was 65.5. This leads to the conclusion that using model-eliciting activities and a valid set of problem cards helps to shape the confidence of junior high school students.
