Blended Learning on Platform DBAC Style on The Topic One Variable Quadratic Equations Promote Problem-Solving Skills For a Prototype of Mathematics Teachers in Grade 3

Abstract

The purpose of this research was to develop and determine the effectiveness of the blended learning management plan. To study learning outcomes and to study problem-solving skills from using the integrated learning management plan on the DBAC Style Platform on One Quadratic Equation of Variables. For the prototype mathematics teacher grade 3, the sample group consisted of 57 mathematics teachers in the second semester of the academic year 2021 under government and private schools. The researcher selects the sample from the open recruitment on a voluntary basis. The design of this study was a single-group experimental study. The research tools were the blended learning management plan. Learning Outcomes Tests and Problem Solving Assessment Tests The time spent in the experiment was 15 hours. The mean score analysis of learning outcomes on one variable quadratic equation (after school) was 92.74 points (92.74%). There was a statistical significance at the .05 level. The score obtained from the problem-solving skills evaluation test (after school) on the subject of quadratic equations with one variable was 80.68 points (80.68%). Problems after school were higher than before. Statistically significant at the .05 level.
