The Impact of Innovative Booklets on Strengthening Awareness of The Green Living Among Secondary School Students

บทคัดย่อ

Quasi-experimental research with non-randomized control group pretest-posttest designs to investigate student awareness of green living. The goal was to instrumentalize generating awareness of green criteria among students, and test its effectiveness. 120 samples were a secondary school student at levels 1-6 aged from 11 to 18, divided evenly into independent experimental and control groups. Simple random sampling was done to ensure equal chances for student selection. Research instruments consist of two types: experimental tools and data collection tools. Experimental tools include two booklets, while data collection measurements were 6-point summated rating scales, ranging from absolutely true to absolutely not true. These tools are used for collecting data before and after experiments, with Cronbach's alpha coefficients ranging from 0.972 to 0.992, respectively. The data analysis accepted all hypotheses in this research. The results indicated that students who read the booklet “Tha Lok Phut Dai Cha Bok Kap Thoe Wa” showed significantly increased awareness of green criteria compared to pre-experiment levels (t-value = -13.609, p-value < .05). By contrast, the control group which read another booklet “Pha Sa Lok 101” revealed no significant difference in awareness of green living posttest compared to pretest (t-value = 0.950, p-value < .05), implying no significant change. Both findings were validated by statistical analysis using the paired-sample t-test. In addition, the experimental group reading Tha Lok Phut Dai Cha Bok Kap Thoe Wa had significantly higher awareness scores compared to the control group reading another booklet (t-value = 22.634, p-value < .05). Girl students showed higher awareness than boys after reading the booklet and completing the post-test
(t-value = -2.357, p-value < .05). The group interested in a single activity demonstrated higher awareness than the one interested in multiple activities (t-value = 2.018, p-value < .05) using independent samples t-test. These findings may help innovate for future learning and serve as a model for fostering green awareness educationally, inspiring further related studies.
