The Development of Scientific Process Skills with the Observational Skill Packages on Classification and Experiment for Grade 6 Students in Satit Elementary School, Phranakhon Si Ayutthaya Rajabhat University

Abstract

               The objectives of this research were 1) to create a package for practicing the observation, classification, and experiment skills on chemistry in everyday life for grade 6/1 students at satit elementary, with an efficiency of 80 / 80; and 2) to compare the skills of observation, classification, and experimentation on chemistry in everyday life before and after using the skill package of grade 6/1 students at satit elementary school, Phranakhon Si Ayutthaya Rajabhat University. The population was 69 students in grade 6 studying course 16102, second semester of the academic year 2018, The sample was selected by cluster sampling in one classroom. The students were grade 6 / 1, which consisted of 33 students. Classification and experiments on chemistry in everyday life. The instruments

                used for this experiment were as follows: the 2 observational skill packages for practicing the observation, classification, and experiment skills, and 2 lesson plans on chemistry in everyday life were appropriate and consistent at very good level. (  = .20.85, S.D. = 7.388) The observational skill test on chemistry in everyday life with 30 items, IOC = 0.901, with reliability of 0.93. The basic statistics used in data analysis were mean ( ), standard deviation (SD), and paired t-test. The results showed that 1) the observational skills packages to develop classification and experimentation on chemistry in everyday life were 80.45, and the efficiency of the result (E2) was 84.23, which was higher than the specified standard 80/80; and 2) the posttest was statistically higher than the pretest at a significant level of .05.
