Inquiry-based Practical Chemistry its Assessment探究為本化學實驗的推行及評估 5 Nov 2005 Programme Scientific Inquiry Inquiry - an active engaging process that mimics the work done by actual scientists. Require students to design some or all of the procedures (ownership and motivation): autonomy Increase the opportunities for students to think about the data they should collect and their presentation Lead to a deeper understanding of scientific concepts In guided inquiry, students choose what data to be collected design the procedures to address the question for investigation In open inquiry, students make almost all the decisions including the questions for investigation Scientific Inquiry “The diverse ways in which scientists study the natural world and propose explanations based on the evidence from their work.” “The activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study natural world.” US National Science Education Standards/readingroom/books/nses/html/pdf/index.html Scientific Enquiry .uk/keystage3/respub/sc_enquiry National Curriculum Handbook for Teacher DfES, UK “Inquiry-based teaching engages students in investigations to satisfy curiosities, with curiosities being satisfied when individuals have constructed mental frameworks that adequately explain their experiences.” “Inquiry-based teaching begins or at least involves stimulating curiosity or provoking wonder. There is no authentic investigation or meaningful learning if there is no inquiring mind seeking an answer, solution, explanation, or decision.” Types of Scientific Enquiry Surveys and correlations (pattern seeking) Controlling variables (fair test) Identification and classification Using and evaluating a technique Technology (make something or invent a system to solve the problem) Using experimental models and analogies to explore an explanation, hypothesis or theory Using secondary sources →appropriate approach to solv
