Development of Local Scientific Activity Modules on the Application of an Ebony Fermented Solution to Enhance Science Project Ability of Mathayom 2 Students

Abstract

The objectives of this research were to investigate scientific local wisdom on the exploitation of the ebony fermented solution of villagers in Chiang Mai Province, to develop and test the efficiency of the local scientific activity modules to enhance science project ability of Mathayom 2 students, and to examine the ability to conduct science projects of Mathayom 2 students after implementing the constructed modules. The population included 50 villagers involved in careers relating to the exploitation of the solution in five districts in the province and 400 Mathayom 2 students from Montfort College. The research instruments consisted of an interview on the solution exploitation, scientific activity modules and local wisdom, and an assessment on science project ability. The data were statistically analyzed for mean, percentage and standard deviation. The research results reveal that different villagers in different districts applied the solution for different purposes, which could be divided into those using it as a toughening agent, those using it as a mold and insect repellent substance, and those using it as a dye fixative. The efficiency (E1/E2) of the scientific activity modules for Mathayom 2 students was 86.33/83.30, which is higher than the predetermined criterion. The 30 student samples taught by using the modules were able to create science projects about the ebony (Diospyros rhodocalyx), which is considered a local wisdom. From assessing the science project ability of the students, it is found that one project was rated at an excellent level and nine projects were rated at a good level.
