This research was intended 1) to study the misconception of mechanical equilibrium of mathayomsuksa five students in provincial schools in Educational Region 2, 2) to compare the conception of mechanical equilibrium of those male and female students, and 3) to compare the conception of mechanical equilibrium of those students in each province. The sample consisted 1,132 mathayomsuksa five students from provincial schools in educational region two. Independent variables were gender and province (Pattani, Yala, Narathiwat and Satun province). The research instrument was a measurement test consisting of 27 question items and covering 10 conceptions of mechanical equilibrium. The reliability of the instrument used in this research was 0.83. In analyzing
the data, for each question item and each conception percentages were calculated by gender and province. To check mean differences between male and female students, a t-test was performed.
A one-way ANOVA was carried out to check the mean differences between provinces, and pairwise differences were established using Scheff 's method.
The findings were as follows:
1. Students were found to have high misconceptions in almost all conceptions tested. For 9 conceptions tested, more than 50 percent of students had misconception. 88.78 percent of students had misconception in the 6th conception and 38.25 percent in the 3rd conception. Students had misconception at the average 66.93 percent.
2. With respect to gender, 64.26 percent of male students had misconception. The highest percentage (88.31 percent) of misconception was in the 6th conception and the lowest percentage (33.52 percent) was in the 3rd conception. On the other hand, 67.55 percent of female students had misconception. The highest percentage (89.00%) of misconception was in the 6th conception and
the lowest percentage (40.45%) was in the 3rd conception.
3. Setting the correct total score of students at one and the incorrect total score of students at zero, the mean conception for each province was as follows: Narathiwat, mean=0.46 and standard deviation=0.21; Pattani, mean=0.36 and standard deviation=0.21; Yala, mean=0.30 and standard deviation=0.17; and Satun, mean=0.22 and standard deviation=0.11.
4. The Misconceptions of male and female students was significantly different at the level
of .05
5. The Misconceptions of students in each province was significantly different at the level
of .05
