A Development of Learning Package in Topic of Linear Equation with One Variable Using Inquiry Method (5Es+D) for Mathematics Problem Solving Ability for Grade 7th Students

Abstract

The objectives of this research were 1) to study the basic information for learning set development, 2) to develop the learning set, 3) to find out the results of using learning set, and 4) to evaluate the learning set. The sample in this research obtained by simple random sampling that were used classrooms in Srikaew Pittaya School, Srirattana district, Srisaket province in the academic year 2015 which contained 32 students as the sample unit. Research instruments used in this research were 1) interview form, 2) questionnaires, 3) learning packages, 4) learning plan, 5) learning achievement test, 6) mathematical problems solving test, and 7) students’ satisfaction survey form. Statistics used to analyze the data were percentage, mean, standard deviation and t-test.

            The research results were as follows:

1. Results after studying basic information for learning sets development showed that 1) all contents were useful for students to use in daily life, 2) the contents, which were able to be used for themselves, their families, and their communities, should be able to use as a part of their future careers, 3) learning sets should have various medias that students could learn by themselves 4) the learning media should be easy to understand and created by using local materials, equipment, and document. 5) teaching activities should let the students to use all medias in their learning activities under the teacher supervisory that teacher could instructed the use of equipment that students might not familiar, and 6) the learning sets should be integrated topic of single linear equation with other subjects.
2. The efficiency of learning sets (E_1/ E₂) equal to 78.85 / 77.27
3. The learning achievement of students and the results of mathematical problems solving ability after learning were higher than before learning statistically significant at the level of .01
4. the students’ satisfaction towards to the learning set were at highest level.
