The Development of Learning Activity Package in Biology in a Lesson on Bacteria Protists and Fungi for Enhance Understanding and Experimental Skills of Twelfth Grade Students

Abstract

In this research investigation, the researcher develops a learning activity package on bacteria, protists, and fungi with a criterion efficiency of E1/E2 at 75/75. The researcher compares knowledge and understanding of the subject under study prior to and after the study by the students under investigation. The researcher enhances the experimental skills of the students under study. The sample population consisted of 45 Matthayom Sueksa Six students from one classroom at a school in Bangkok Metropolis using the method of simple random sampling. The research instruments consisted of (1) a learning activity package on bacteria, protists and fungi; (2) five lesson plans; (3) a test of bacteria, protists, and fungi; and (4) an evaluation form of experimental skills. Data were collected by an evaluation of the relevant knowledge and understanding prior to and after the study and an evaluation of the experimental skills demonstrated during the study. The statistics used in data analysis were arithmetic mean, standard deviation, and dependent t test. Findings are as follows: The learning activity package constructed exhibited efficiency according to the set criteria of E1/E2 at 75/75. The knowledge and understanding of bacteria, protists, and fungi of the students under study exhibited the mean after the study at a higher level than prior to the study at the statistically significant level of .05. The experimental skills of the students under investigation exhibited the means of all activities at a very good level (M = 4.63 from the full score of 5, S.D. = 0.06).
