The Taxonomy of Predict-Observe-Explain (POE) as a Teaching Strategy and Thinking Process of Chemistry Stakeholders

Abstract

Predict-observe-explain (POE) is a strategy being used during scientific investigations and experiments. However, POE-related studies mainly focused on its validity and reliability as a teaching strategy in classrooms. Thus, this paper extends the context of POE strategy as science process skills, as cognitive thinking skills in performing experiments, and answering scientific inquiries among chemistry stakeholders: students, teachers, and chemists. The study sees POE as a way to develop critical thinking and builds the skills needed for further academic and professional endeavors in the different fields of science. Through a constructivist grounded theory methodology using focus group discussions for students and in-depth interviews with the teachers and chemists, the study: described how students, teachers, and chemists exemplified POE strategy in terms of its process, and identified mutual patterns of POE process from the chemistry stakeholders. The study revealed that: student POE taxonomy is focused on basic processes and structures of POE; teacher POE taxonomy is a guide in their lesson planning; and chemist POE taxonomy is based on local and international compliance during experimentation. Therefore, POE is a science process skill for chemistry stakeholders where the POE taxonomy used by the chemistry stakeholders are different based on experiences, needs, and context.
