Abstract

The aim of this research is to develop a valid, practical, and effective interactive video-based storytelling learning tool to enhance students^ numeracy literacy skills in geometry. The research follows the Research and Development (R&D) approach using the Plomp development method. The product of this R&D is an interactive learning video that underwent validation by two content validators and three media validators, as well as practicality and effectiveness testing by one teacher and 22 first-grade students in Surakarta.

Data collection techniques included observation to gather data from various mathematics learning YouTube channels, documentation to collect semester assessment data from the first-grade students, questionnaires to gather data on the validity and practicality of the product, and tests in the form of pretests and posttests to measure the effectiveness of the product. Data analysis methods involved Aiken^s validity analysis, percentage calculation for practicality analysis, and N-Gain and paired t-test for analyzing the effectiveness based on pretest and posttest results.

The results of the research indicate that: (1) The developed product is valid in enhancing students^ numeracy literacy skills in geometry, as evidenced by the validation scores from content and media experts. (2) It is practical for use in geometry learning. (3) The product is effective in improving students^ numeracy literacy skills, as indicated by the significant difference in mean scores according to the paired t-test, and the moderate increase in N-Gain scores.
