Developing Interactive Multimedia for Pythagorean Theorem Learning Using Articulate Storyline 3: Effects on Student Achievement

Abstrak

Low student achievement in mathematics, particularly on the Pythagorean Theorem, at SMP Negeri 1 Kendari has been attributed to the dominance of conventional instructional methods that inadequately leverage available technology. This study aims to: (1) develop interactive multimedia learning based on Articulate Storyline 3 for the Pythagorean Theorem topic using the Lee & Owens development model, (2) determine the feasibility level of the multimedia based on expert validation, and (3) assess its effectiveness in improving Grade VIII student learning outcomes. A Research and Development (R&D) approach was employed following the five-stage Lee & Owens model: needs assessment and front-end analysis, design, development, implementation, and evaluation. Twenty-eight Grade VIII-6 students at SMP Negeri 1 Kendari participated in the study. Data were collected through expert validation sheets, student response questionnaires, and pre- and post-test instruments. Results indicated that the multimedia received a material expert validation score of 85.5% and a media expert validation score of 88.49%, both categorised as “Highly Feasible.” Student testing revealed an improvement in mean scores from 63.5 (pre-test) to 84.6 (post-test), yielding an N-gain score of 0.60 (56.4%), classified as “Moderately Effective.” Student engagement with the media reached 71.6%. It is concluded that the Articulate Storyline 3-based multimedia developed through the Lee & Owens model is valid, feasible, and effective for mathematics learning on the Pythagorean Theorem topic.
