A development of 3-dimensional material design skills by using Pro/Desktop of Mattayom Suksa three students of Lueamnatwittayakom school under the office of the secondary educational service area 29
Abstract:
The research aimed to develop 3-dimesional material design skills by using
Pro/Desktop of Mattayom Suksa Three Students of Lueamnatwittayakom School under
the Office of the Secondary Educational Service Area 29, to compare 3-dimensional
material design skills before and after the operation and design skills of the experimental
group that used a computer-assisted instruction and a controlled group that used a traditional
learning method.
The samples used in the research were Mattayom Suksa three students of
Lueamnatwittayakom School in the first semester of the academic year 2013. The
samples that were derived by a purposive random sampling consisted of an experimental
group of 30 and a controlled group of 30. The research instrument consisted of the
computer-assisted instruction, the learning achievement test, the lesson plans on the
3-dimensional material design, the students behavior observation format, daily records,
a test on the design skills and interviews. Statistics used in data analysis were percentage,
mean, standard deviation, Mann-Whitney U Test and Wilcoxon Signed Ranks Test.
The research findings were as follows :
1. The development of 3-dimensional material design skills had three circuits,
each of which consisted of 3 steps: planning, implementing as planned and observing,
reflecting. The results of the implementation showed that the development of 3dimensional
material design skills had positively contributed to the design skills of
the students in the study.
2. The students who learned by using the computer-assisted instruction
developed higher design skills than before with a statistical significance of .01.
3. The experimental group had higher 3-dimensioinal material design skills
by using Pro/Desktop than the controlled group with a statistical significance of .01.
