A Study of the Guided Discovery Method in Teaching Grade Nine Mathematics

The purpose of this research is to study the guided discovery method in teaching mathematics at the high school level. A quantitative research method was used to compare the mathematics achievement between the control group and the experimental group. The students from the control group were taught by formal teaching method. The students from the experimental group were treated with guided discovery method. The designed adopted in this study was the posttest only control group design. The effects of the guided discovery method were tested in Basic Education High School (Branch) Alantapo, Hlegue from Yangon Region. Learning materials were selected from Grade Nine Mathematics textbooks. Independent samples t-test was used to analyze whether there were significant differences between the two groups. The result showed that the students who received the treatment by guided discovery method were significantly better than those who received formal teaching method for BEHS (Branch) Alantapo, Hlegue (t=3.154, P
