This study aimed to develop and evaluate video-based instruction on shallot tea processing, compare Grade 9 students’ learning achievement before and after the intervention, investigate their satisfaction, and examine relationships among the satisfaction components. The study employed a research and development approach combined with a one-group pretest–posttest design. The participants were 36 Grade 9 students at Surin Ratchamongkol School, Thailand, selected through purposive sampling. The research instruments comprised video-based instruction on shallot tea processing, a learning achievement test, and a 15-item satisfaction questionnaire covering content, visual presentation, and audio presentation. The instruments were evaluated by three experts. Data were analyzed using mean, standard deviation, Cronbach’s alpha, corrected item–total correlation, a paired-samples t test, the Shapiro–Wilk test, and Spearman’s rank correlation coefficient. The findings showed that the developed video systematically presented six components of shallot tea processing and received a high overall quality rating from the experts (M = 4.33). Students’ posttest scores (M = 14.86, SD = 0.351) were significantly higher than their pretest scores (M = 10.81, SD = 1.546), t(35) = 15.356, p < .001. Overall student satisfaction was high (M = 4.23, SD = 0.664), with content receiving the highest rating. The satisfaction questionnaire demonstrated excellent internal consistency (α = .918). Significant positive relationships were found among satisfaction with content, visual presentation, and audio presentation (rs = .544–.763, p < .001). These findings indicate that video-based instruction, when integrated with demonstrations and hands-on activities, has potential to support students’ learning of agricultural product-processing procedures.

This study aimed to develop an agricultural learning activity package on native chicken raising for Grade 9 students, compare students’ learning achievement before and after using the package, and investigate their satisfaction with the learning experience. A developmental research approach incorporating a one-group pretest–posttest design was employed. The participants were 30 Grade 9 students enrolled in an elective agriculture course at Phraibueng Wittayakom School during the second semester of the 2023 academic year. The learning activities were conducted at the school’s Living Agricultural Learning Center. The research instruments comprised the agricultural learning activity package, a 15-item multiple-choice achievement test, and a 12-item satisfaction questionnaire. The package and research instruments were reviewed by three experts before implementation. Data were analyzed using frequency, percentage, mean, standard deviation, and a paired-samples t-test. The results showed that the students’ mean posttest score (x ̅ = 10.77, S.D. = 1.33) was significantly higher than their mean pretest score (x ̅ = 7.53, S.D. = 1.96), t(29) = −9.38, p < .001. Their overall satisfaction with the learning experience was at a high level (x ̅ = 4.29, S.D. = 0.41). The findings indicate that the developed package provided a useful structure for connecting knowledge of native chicken raising with active and practical learning and was associated with improved learning achievement among the participating students. The package may be used as supplementary instructional material for lower-secondary agricultural education, with appropriate adaptation to local contexts and available learning resources.

This study examined and prioritized the competency-development needs of secondary school agriculture teachers in Phra Nakhon Si Ayutthaya Province, Thailand. A quantitative cross-sectional survey design was employed. The population comprised 73 teachers in the Occupational Learning Area, from whom 45 teachers responsible for agriculture or agriculture-related subjects were selected through cluster sampling by school size followed by simple random sampling. Data were collected using a researcher-developed questionnaire covering five core competency domains and six functional competency domains. The questionnaire was evaluated by three experts for content validity using the item–objective congruence index. Data were analyzed using frequencies, percentages, means, standard deviations, and descriptive rankings. The overall need for core competency development was high (M = 4.32, S.D. = 0.21). Teacher ethics and integrity was the highest-rated core competency and the only domain rated very high (M = 4.54, S.D. = 0.36), followed by self-development and teamwork. The overall need for functional competency development was also high (M = 4.26, S.D. = 0.21), with teacher leadership receiving the highest rating (M = 4.39, S.D. = 0.35), followed by community relationships and collaboration for learning management. Across all 11 domains, teacher ethics and integrity, teacher leadership, self-development, and community collaboration emerged as the leading priorities. The findings demonstrate broad competency-development needs and suggest that professional development programs for secondary school agriculture teachers should integrate professional ethics, leadership, continuous self-development, and school–community collaboration.
