Abstract
This research and development project had the objective of studying the format and results of a training project to develop knowledge about the safe use of health products that was designed for adolescents and tested on secondary school students in Khon Kaen Province. For the design phase, input was gathered from 28 key informants. For the process of developing knowledge and assessment, the study relied on data from 34 students who were in grades 9 - 12. The tools used in the research consisted of a pre-test and a post-test before and after the training project, an activity recording form, and satisfaction assessment forms, which were used to collect both quantitative and qualitative data. The data collected were analyzed using descriptive statistics, inferential statistics such as dependent t-test, repeated measures Analysis of Variance, and qualitative data analysis.
The results were as follows: the format of the research-based knowledge development project that was created consisted of 1) improving knowledge of health products 2) improving practical skills by learning from practice and 3) improving skills through learning from undertaking the project. The results of knowledge improvement demonstrated that before model development, students had a mean knowledge score of 9.88 (SD = 0.57) and after model development the students had a mean knowledge score of 15.24 (SD = 0.55), which had a statistically significant difference (p < .001).
The results of the evaluation on student knowledge improvement after 2 months of participation in the research showed that the sample group had a mean knowledge score of 20.56 (SD = 0.24) when differences of mean scores from all 3 tests were compared by using the repeated analysis of variance statistics. The three knowledge scores differed with statistical significance (p < .0001). Comparing in pairs, mean knowledge scores before and after the project were different to a statistically significant degree (p < .001). The mean pre-test and post-test scores differed by 5.35 points (95% CI: 4.24 - 6.47) and the score before model development was statistically different from that after the second development (p < .001) by 10.68 points (95% CI: 9.54 - 11.81). The mean scores after development, when measured the first time and measured again at the second time, differed to a statistically significant degree (p < .001), and differed by 5.32 points (95% CI: 4.18 - 6.47). After completion, 52.9% of students reported that they were “very satisfied” with the project overall.
