Abstract

The study aims to examine students^ collaboration skill during the implementation of Predict-Observe-Explain-Extend (POEEd) strategy. The use of socio-scientific issue (SSI) supported the POE strategy that was implemented on Acid Base topic. This research adopted a pre-experimental method. A total of 65 eleventh grade students were enrolled as research sample. They were selected by random sampling. The Collaboration Skill Rubric (CSR) as the instrument in collecting data consist of four aspects that was breakdown into 20 items. Content and construct validity was ensured by a group of expert in chemistry education. Then, five observers engaged for interrater reliability measurement. The CSR had a very good reliability so can be used as data collection tools. Observation toward students^ collaboration skill was done in four meetings with SSI as the starting point of POEEd strategy. The data of students^ collaboration skill was analysed descriptively and by ANOVA test to look the mean different among meetings and aspect of collaboration skill. The result showed that there was no significant different in collaboration skill totally on the fourth implementation of POEEd strategy. However, for the detail analysis indicated that there were significant different of students collaboration skill on commitment and responsibility aspects (95% level of confidence) and for communication aspect at 90% level of confidence. Overall, students had a good collaboration skill and their best performance was gained during discussion about the use of natural indicators of acid base. In this moment, students was challenged to argue and get best solution related to the phenomena of abuse of borax for food. The study suggests that the use of familiar SSI in constructivist strategy improve students^ competence and quality of chemistry learning process.
