Abstract:
The learning package is considered an educational innovation that very important to
develop learning and teaching Mathematic subject, learning achievement and learner quality. The objectives of this research were 1) to develop a set of mathematics learning activities in factoring the second degree to be effective according to the criteria 80/80 2) to study the development results of mathematics learning activity sets 3) to investigate grade 8 students satisfaction with the mathematics learning set of activities.The Sample selected by multi-stage random sampling,consisted of 64 grade 8 students in Phuengdaedwittayakarn school Mukdahan Province. The instruments use to collect the data were a set of mathematics learning activities is suitable at the high level, a learning achievement test with difficulty 0.35 -0.80 and discrimination 0.25-0.70 reliability was 0.81, and Student satisfaction questionnaire discrimination 0.21-0.79 reliability was 0.89 .The information obtained was analyzed using percentage, mean, standard deviation and t-test.
The results showed that 1) Mathematics Learning Package on Factoring Polynomials of The Second Degree indicated the efficiency of 82.88/80.61 2) the result of the development of mathematics learning activity set revealed that 2.1)the amount of difference in the learning achievement by use the mathematics learning achievement before and after learning was found to be significance at .05 2.2) the amount of difference in the learning achievement of the experimental group after learning was found to be higher than that of the controlled group,and was significance at .05 3) The students satisfaction with the Mathematics learning activity sets was found to be at
the highest level.
