Targeting Chemistry Competencies on Plastic Circular Economy with Technology-assisted Citizen Inquiry: A Proposal of Learning Matrix

This paper focuses on designing learning matrix activities to target core chemistry competencies. Besides, this paper will describe the role of technology in facilitating students in achieving these competencies. Based on China Senior High School Chemistry Curriculum (Wei, 2019), there are five chemistry core competencies: "1) macroscopic identification and microscopic analysis, 2) changes and equilibrium, 3) evidence-based reasoning and modeling, 4) scientific inquiry and innovation, 5) scientific attitude and social responsibility". Furthermore, due to the pivotal chemistry three representation levels (macroscopic, microscopic, and symbolic), researchers generated the sixth competency (i.e., the link between macroscopic, microscopic, and symbolic). These activities are designed for two weeks of summer camp. Many learning strategies are used in this learning matrix activities, such as interactive lessons, hands-on activities (e.g., stop-motion project), laboratory experiments, flipped inquiry-based learning, citizen inquiry, field trips, and exhibitions. Besides, various technologies are used in this learning matrix activities, such as video, mobile technology, and camera. These activities in the matrix are expected to promote students' chemistry competencies, especially on polymer, plastic, and circular economy topics.
