Abstract

The purposes of research aim to 1) develop the efficiency of learning’s packages about the atmosphere according to the criterion of 80/80 2) develop the science learning achievement by using learning’s packages about the atmosphere of mathayomsuksa 1 students according to the mastery learning and 3) develop the critical thinking skills by using learning’s packages about the atmosphere of mathayomsuksa 1 students according to the mastery learning. The research population consisted of 25 students who studying in mathayomsuksa 1 in the 2 semester of the academic year 2019 of Wat Thamnawa School, Phra Nakhon Si Ayutthaya Province. The research instrument were 1) learning’s packages about the atmosphere and 3) a science achievement test and 3) a critical thinking skills test. The statistics used for data analysis were percentage, mean and standard deviation. The findings were as follows: 1) the efficiency value (E₁/E₂) of learning’s packages about the atmosphere was at 83.60/83.80 2) the science learning achievement of 25 students (100 %) were higher than the pre-test scores and 3) the critical thinking skills of 22 students (88 %) were higher than the pre-test scores.
