Abstract: This study aimed to develop a STS-based learning unit on biocontrol for secondary school students to enhance their understanding of biocontrol as well as raise awareness in their local environment. They should be able to connect science in classroom to local problems in their community. This study focused on the collaboration between students, school teachers, and local sages in supporting the authentic learning of students by using biocontrol experiment as a case study. The teachers used STS approach (Science, Technology and Society) to construct the novel lesson plan on biocontrol by using local materials from school vicinity and/or student's farm. The students learned basic techniques in controlling plant pathogens and insect pests by biological agents, both from school and from visiting the local farm and discussing with local experts. Teachers then encouraged them to design and conduct their own projects to solve problems on plants, fruits and vegetables diseases in their own area. Teachers supported them with certain laboratory materials and equipment as well as necessary textbooks and journals. Four instruments were used to assess students' achievement: pretest and posttest, questionnaire on awareness, semi-structured interview, and classroom observation. The results showed a significant increase in students' understanding of biocontrol concepts and awareness of the local problem. The students applied and integrated the knowledge learned to help solving problem on plants' diseases in their community. © Common Ground, Kanrawee Pewnim, Watcharee Ketpichainarong*, Pintip Ruenwongsa.
