The Learning Experiences by using a Set of Science Experiment Activities to Develop Scientific Process Skills for Preschool Children in 3rd Kindergarten.

Abstract

The objectives of this study were 1) to find the efficiency of the learning experiences by using a set of science experiment activities set according to the criteria 80/80 2) to compare science process  skills of preschool children, 3rdkindergartenbefore and after organize learning experiences using the
science experiment activity set 3) to study the effectiveness index of learning experiences management  using And 4) to study the satisfaction of preschool children in 3rdkindergarten on the learning  experiences by using the science experiment activity set. The sample groups used in this study were
preschool children, kindergarten, year 3/2, municipal school 4 (Ban Sai Thong), semester 1, academic year 2017, number 19, which were obtained by clustering random sampling method.  Educational tools consist of 1) a set of science experiment activities to develop scientific process skills
in the amount of 20 sets 2) plans The learning experiences by using a set of science experiment  activities set Science plan 40 3) assessment of science process skills of preschool children in 3^rd  kindergarten.The statistics used for data analysis were percentage, mean, standard deviation and  testing the hypothesis with a t-test                                                                                                                                                                                                                                                                  The study indicated that                                                                                                                                                                                                                                               1) The results of learning experiences management by using a set of effective science experiment activities For preschool children in 3rdkindergarten, the efficiency is 83.05 / 82.63 which meets the criteria.                                                                                                                                                                                                 2) Scientific process skills for preschool children, 3rdkindergartenafter organizing learning experiences using science experiment activity sets higher than before learning experienceswith statistical significance at the level of .01                                                                                                                                                             3) The effectiveness index of learning experiences management by using the science experiment activity set that has been arranged by using science activity set is equal to 0.70, indicating that early childhood development has increased the percentage of scientific process skills 70
4) Satisfaction with the learning experiences arrangement using the overall science experiment activity set was at a high level (x̄= 2.63, S.D. = 0.48)
