Abstract

Mathematical problem solving skills are important for high school students, but are still low. The contributing factor is that learning does not emphasize problem solving and involve students. Teaching materials are not suitable with students' characteristics. Teacher skills in developing problem solving-based learning are still low. This study aims to develop a learning module based on Project Based Learning (PBL) to improve the mathematical problem solving skills of high school students in grade XI on the sequence nd series topic. Testing the effectiveness of the PBL module on improving students' mathematical problem solving skills. This research uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model to develop the PBL module. In the analysis stage, data were collected through observation, questionnaires, interviews, and tests to find out students' problems in learning the material of sequence nd series. The test results of students' mathematical problem solving skills showed that 91% of students had low mathematical problem solving skills. At the design stage, the PBL module was designed by considering the results of the student needs analysis and the characteristics of the sequence nd series material. This module contains various learning activities that involve students actively in solving problems related to everyday life.In the next stage, the PBL module that has been designed will be implemented in the experimental class and tested for its effectiveness in improving students math problem solving ability.

Abstract

This study is a validation and instrument-development research whose primary goal is to examine and ensure the psychometric quality of a Logical–Mathematical Intelligence (LMI) questionnaire for Senior High School students. LMI, as a fundamental aspect of scientific reasoning, requires a well-established measurement tool. The adapted instrument consists of 24 items using a five-point Likert scale and was constructed based on Gardner’s five core LMI dimensions (numerical ability, logical reasoning, problem solving, pattern recognition, and deductive/inductive thinking). Data were collected online from 317 high school students through convenience sampling. Analysis was performed using the Rasch Model (Winsteps 3.73). The results indicate that the instrument demonstrates adequate unidimensionality (raw variance explained 33.3%) and excellent reliability (Cronbach’s Alpha 0.89; Item Reliability 0.96). All items were found to be fit and functioning properly, with strong discriminative power (Item Separation 4.98), indicating that the instrument can classify item difficulty into seven distinct levels. These findings explicitly confirm that the adapted LMI questionnaire meets international psychometric standards and is valid for mapping the logical–mathematical reasoning abilities of high school students.
