Abstract:
ABSTRACT
The purpose of this research were : 1)to study the development of activity packages
Entitled Rate of Reactions by using problem-based learning for Matthayomsuksa 5 Students in
Order to meet the criteria set at 80/80, 2) to compare the students learning achievement before and
after learning by using activity packages Rate of Reactions by using problem-based
learning for Matthayomsuksa 5 students, 3) to investingate the effectiveness index of the activity
packages entitled Rate of Reactions by using problem-based learning for Matthayomsuksa 5
students, and 4) to ezplore the satisfaction of the students towards learning through activity packages
entitled Rate of Reactions by using problem-based learning for Matthayomsuksa 5 students. The
samples were 25 Matthayomsuksa 5 students studying in the second semester of the academie year
2015 at Sakaephittayakhom School in Satuk Distriict, Buriram Province, selected by simple random
Sampling. The research instrument were: 1) 5 activity practice packages, 2) 10 lesson plans, 3) a 30-
item with 4 multiple-choice achievement test, with the difficulty between 0.53-0.80,the
discrimination between 0.29 0.57 and the reliability value at 0.29,and 4)20-items questionnaire on
students satisfaction with 5-rating scale.The statistics used for datd analysis were percentage, mean
standard deviation, E1 /E2 and E.I. The hypothesis was tested by using dependent samples t-test.
The results of the study werer as follows:
1. The efficiency of activity packaged :Rate of Reactions by using problem-
Based learning for Matthayomsuksa 5 students was 82.48/81.07 which was attain the criteria set of 80/80.
2. Thestudents learning achieve,ent after learning with the activity packages entitled
Rate of reactions by using problem-based learning for Matthayomsuksa 5 students was higher
than before with the statisticaiiy significant difference at the level of .05.
3. The effectiveness index of the activity packages Reactions by using
Problem-based learning for Matthayomsuksa 5 students was 0.6773 which showed that the students
Knowledge increased 67.73%
4. The satisfaction of the students the activity packages Rate of a
Chemical Reactions by using problem-based learning for Matthayomsuksa 5 students as a whole was at a highest level.
