運用立即反饋系統促進科學學習

Abstract

本論文探討立即反饋系統運用於科學教學的效益以及有效策略。針對以往的實徵研究進行後設分析，本論文提出運用立即反饋系統有助於提升學習成效的證據，並指出「搭配立即反饋系統施行小組討論」有助於大幅提升學生的學習成效。本論文進一步執行實徵研究，比較不同小組討論模式搭配立即反饋系統，對於學生討論過程以及學習成果的影響。根據實徵研究的成果，本論文開發新世代的立即反饋系統──CloudClassRoom (CCR)，並改良實行小組討論的策略，以期提升科學教學的成效。實徵研究的成果佐證CCR搭配小組討論的可行性與有效性。鑒於CCR的開發成果以及學生的實際討論模式，本論文建議搭配立即反饋系統進行科學教學的注意事項，並提出嶄新的研究方向。Clickers are widely advocated as a useful tool to break up the passive learning format of science lectures. It is expected that the use of clickers will actively engage students in thinking about the content presented during the lecture. Regarding the increased investment in clickers by schools, it is critical to examine whether clickers are worth the investment and how to make good use of clickers to promote active learning. This dissertation is thus done to answer these two questions. A meta-analysis on empirical clicker studies is performed to examine the relative effectiveness between conventional and clicker-integrated lectures. Statistical evidence supporting the superiority of clicker-integrated lectures is obtained. Moreover, it is found that using clickers with peer discussion is a very promising strategy to promote learning gains. Along with this research line, an empirical study is conducted to evaluate the relative effectiveness between different models for implementing peer discussion with clickers. Characteristics of productive clicker-integrated peer discussions are identified, including explanation-oriented, intellectually diverse, iteratively justified, and collectively participated. Issues related to the cultivation of productive clicker-integrated peer discussions are raised and discussed, including the balance between education and entertainment, demonstration of the weakness of the appeal to authority, tools for explicating explanations, and heterogeneous mixture within groups. Practical strategies are discussed to resolve these issues. An innovative design isthen proposed to transform clickers into a more powerful pedagogical tool. An empirical study, which demonstrates the feasibility and effectiveness of the design ideas in a real classroom setting, is presented as a closure to this dissertation.
