DEVELOPMENT AND VALIDATION OF GEOMETRY CITY STEM MODULE (MBG)

Abstract

The objectives of this paper are to assess the development and content validity of a module
developed to assess higher order thinking skills, conceptual knowledge, and critical thinking skills.
According to the findings of descriptive statistical, topics Space and Fractions were identified as the most
difficult topics to study in Mathematics Year 5 by 48 teachers who taught pupils’ elementary school. In this
study, a prototype is designed using the ADDIE model. The content validity of the instrument was evaluated
using the judgments of eight experts. The item content validity index (I-CVI) and the scale content validity
index were used to assess content validity (S-CVI). Six dimensions were identified: interface, picture, text,
content, teaching and learning process method, and objective achievement. For interface, picture, text,
content, teaching and learning process technique, and objective achievement, the item content validity index
(I-CVI) varied from 0.89 to 1, and the scale content validity index (S-CVI/Ave) was 1.00, 1.00, 1.00, 0.93,
0.95, and 0.89, respectively. According to the findings, the module has high content validity and may be
utilised to increase HOTS, conceptual and critical thinking skills, and mathematics content understanding
among elementary school students.
