Learning Experience Topic in Dissolve Nitrate Analysis by Spectrophotometric Method for Vocational Agricultural Students

Abstract

The objective of this research was to study the achievement of vocational agriculture students’s learning experience in analyzing the dissolved nitrate by spectrometer photometer. The samples were 23 fisheries and plant science students of College of Agriculture and Technology, Nakhon Si Thammarat Thailand.  The study tools were learning outcome test on learning experience, student behavior test, and learning achievement test. The learning outcome evaluation by professionals showed that the learning experience in analyzing dissolved nitrate by spectrometer photometer was appropriate for agricultural vocational students at the high level (2.81 from 3, S.D = 0.40). The behavior evaluation showed that the students paid attention to learning with the high level (8.43 from 10) and the learning achievement evaluation showed that 31 percent of the subjects were able to answer 80% of the questions correctly.
