Journal Title: Batı Anadolu Eğitim Bilimleri Dergisi (BAED) - Year 2015, Vol 6, Issue 11
Abstract
In this study, it has been investigated the role of teaching applications which intend to develop visualization skills of the students on visualization usage and effective visualization usage in problem solving. It is an experimental research based on an experimental pre-‐‑test post-‐‑test model. The experimental and control groups consist of the 8th grade (14-‐‑15-‐‑year-‐‑old) students of a secondary school in Izmir/ Turkey. The experiment group was formed of 21 students, while the control group was formed of 22 students. In the experimental group, teaching process of “systems of linear equations” subject was carried out by using computer-‐‑based visual representations and visualization practices. Before and after the teaching application and practices, the status of visualization usage and effective visualization usage of students was examined with “Abstract Thinking in Mathematics Test” which has been developed by the researchers. Results showed that to practice visualizing on routine problem solving effect the students´ preferences on using visual modes of thought and problem solving when they solve non-‐‑routine problems. According to posttest scores of experimental group, usage and effective usage of visualization in problem solving were increase.
