摘要：This paper aims to share the use of Tracker—a free open source video analysis and modeling tool—that is increasingly used as a pedagogical tool for the effective learning and teaching of Physics for Grade 9 (Secondary 3) students in Singapore schools to make physics relevant to the real world. We discuss the pedagogical use of Tracker, guided by the Framework for K-12 Science Education by National Research Council, USA to help students to be more like scientists. For a period of 6 to 10 weeks, students use a video analysis coupled with the 8 practices of sciences such as 1. Ask question, 2. Use models, 3. Plan and carry out investigation, 4. Analyse and interpret data, 5. Use mathematical and computational thinking, 6. Construct explanations, 7. Argue from evidence and 8. Communicate information. This paper’s focus in on discussing some of the performance task design ideas such as 3.1 flip video, 3.2 starting with simple classroom activities, 3.3 primer science activity, 3.4 integrative dynamics and kinematics lesson flow using Tracker progressing from video analysis to video modeling, 3.5 motivating performance task, 3.6 assessment rubrics and lastly 3.7 close mentorship. Initial research findings using pre- and post- perception survey, triangulated with student interviews suggest an increased level of students’ enjoyment such as “I look forward to physics lessons”, “I really enjoy physics lessons” and “Physics is one of the most interesting school subjects” etc for the more mathematically inclined students. Most importantly, the artefacts of the students’ performance task in terms of the research report and Tracker *.TRZ files, further suggest that the use of the Tracker for performance tasks, guided by the Framework for K-12 Science Education by National Research Council, USA, can be an innovative way to mentor authentic and meaningful learning that empowers students to be more like scientists.
