基於混合式學習機制之引導發現實驗教學模式以提升實務學習成效之研究

Abstract

為改善輪機工程學系學生電學相關課程學習成效並提升實務技能，本計畫以應用電學實驗課程為例，提出基於混合式學習機制之引導發現式實驗教學模式，引導發現式實驗教學模式較符合在實驗室場域中教學的需求，並是協助教師調整教學步調和控制教學進度之有效適應性方案。所採用的教學模式在學生進行各實習單元前或過程中，會給予適當口授講解學習單元動作原理、理論波形分析和實驗步驟說明，並將實驗教材組織成為有用的形式。透過問題提問的方式與學生互動激發探索學習動機並強調學習重點，讓學生經由執行實驗操作與量測、觀察與比較量測與理論波形、發現問題與解決問題、結果探究與討論說明等學習步驟，引導學生從各單元實驗的過程中發現與驗證學習單元動作原理並累積實務製作經驗。另外，為因應所發展的教學模式，需開發設計具實務應用之實習教學單元內容和教具，再配合所建置之網路化遠距學習與實驗輔助平台以強化精熟學習環境，讓學生可不受課堂時間和疫情限制下，透過網路可作不定時、不定點、不限次數的反覆實驗練習直到完全瞭解並熟悉所學原理，以達精熟學習目的。最後，本計畫透過量化和質性的評量工具和問卷量表，來驗證所提出的教學模式之可行性和學習成效之改善。

To improve the learning effectiveness of the practice courses for marine engineering students and enhance their practical skills, this project takes the applied electrical experiment courses as an example and proposes a guided discovery experimental teaching (GDET) model based on a blended learning mechanism. The GDET model can conform to the demand for teaching in the laboratory field. It is an effective and adaptable plan to assist teachers in adjusting the pace of teaching and controlling the teaching progress. The methodology adopted will give proper oral instruction to explain the operation principle of the learning unit, theoretical waveform analysis and experimental procedures before or during the course of each unit, and coordinate the experimental materials into useful forms. Interacting with students through quizzes stimulates the motivation of exploration and learning as well as emphasizes the key points of learning. Let students perform the learning steps: experimental operation and measurement, observation and comparison of measurement and theoretical waveforms, problem discovery and solving, outcomes exploration and discussion, to guide students to discover and verify the operating principle from the experimental processes and improve practical experience. Besides, in order to respond to the teaching model, it is necessary to design practice teaching materials and aids, and then cooperate with an Internet-based distance experiment assistant learning platform (DEALP) built to strengthen the proficient learning environment. Coupled with the DEALP, students can do unscheduled and unlimited self-repetitive exercises through the Internet without being restricted by the class time until they fully understand the learned principles to achieve the purpose of proficient learning. Finally, this project verifies the feasibility and learning effectiveness of the proposed teaching model through qualitative and quantitative assessment tools and questionnaires.
