Abstract:
The aim of this research was to study the ability of the proportion of undergraduates at Faculty of Science, Srinakharinwirot University. The subjects consisted of third-year science education undergraduates in 5 majors, Mathematics, Science–Physics, Science–Chemistry, Science–Biology and General science, Faculty of Science, Srinakarinwirot University, who registered in the first semester of the academic year 2013. Thirty students in each major
(150 in toto) were sampled by simple random sampling. The instrument was the ability test in proportion, and the
data were analyzed by descriptive statistics. The finding showed that the overall average score from the ability test in proportion was 21.17 ± 5.63. It revealed that students had high ability in proportion. The highest average score was students in Mathematics (22.33 ± 5.22), followed by students in General Science (21.73 ± 4.82), Science–Biology (21.30 ± 5.13), Science–Physics (21.16 ± 6.06) and Science–Chemistry (19.33 ± 6.66), respectively.
