Abstract

This research was motivated by the observed low ability of students to solve mathematical problems effectively. To address this issue, the Teaching at the Right Level (TaRL) approach, which adapts instruction based on students’ current learning levels, was applied in combination with web-assisted learning tools to enhance engagement and accessibility. The web-assisted TaRL approach integrates adaptive teaching with online materials such as concept maps, interactive videos, and assessments tailored to student needs. The study aimed to evaluate the effect of this approach on students’ mathematical problem-solving skills. Using a posttest-only control group design, 70 students were purposively sampled and divided into an experimental group (34 students) receiving the web-assisted TaRL intervention, and a control group (36 students) undergoing conventional learning. The assessment consisted of three validated descriptive questions measuring problem-solving ability. Results showed that the experimental group achieved a higher average score (82.45) compared to the control group (65.65). Both groups met assumptions of normality and homogeneity, confirming the appropriateness of parametric testing. The independent samples t-test revealed a statistically significant improvement (p < 0.05) in the experimental group’s problem-solving skills. While these findings support the effectiveness of the web-assisted TaRL approach, limitations include the relatively small sample size and short intervention duration. Future research should consider larger, more diverse populations and explore long-term effects to strengthen generalizability and further optimize the integration of technology in adaptive learning.

Abstract

The 21st century requires individuals toahaveatheaabilityato think_comprehensively, especially in criticalaandacreative_thinking. The result of the PISA study show that the literacy skills of Indonesian student are still relatively low, including in terms of numeracy or mathematical problem solving. Preliminary data shows that most students have a "normal" feeling about math lessons (45%) and feel less confident when-learning maths (47.2%). Teachers also face difficulties in providing learning materials that_are in-accordanceawith the level of students' abilities due to heterogeneity in the classroom.

In addition, thearesultsaofatheaanalysisaof-the classical-learning-completenessatest show that theaproportion of completeness of materialistic problem ability is achieved. Theoretically, this research contributes to the study of technology-based learning with the application of TaRL, and is able to support constructivistic theory and effectively improve students' mathematical problem-solving skills.
