Impact of Model Drawing and Visualization to Solve Word Problem of Equation at Grade-8 in Nepal

This research aim is to know whether teaching word problems of mathematics to young learners through model drawing and visualizing is effective or not at basic school, especially for grade 8 students in Nepal. For this, 25 students were randomly selected as an experimental sample and pre-test consisting six-word problem administrated to the students to determine the baseline. The lesson structure of the experimental class was composed of Hogan & Forsten (2007)'s eight steps of model drawing approach guided through interpretation, visualization and mathematical equation. Finally, post-test consisting six-word problem administrated to the students to detect the effect. At last, through social validity survey students' opinions about model drawing and visualization were collected. The data was analyzed using parametric t-test. The result shows a significant difference between the mean achievement of students before and after treatment. The use of model drawing, visualization and its impact on student learning shows that this approach improves student's knowledge, comprehension and application ability to solve word problems of equation.
