直流偏壓電路教具之開發及其應用

Abstract

研究者身為電子科教師多年教學發現，在教授直流偏壓電路單元時，由於電路圖的抽象概念，導致大多數電機與電子群學生無法轉換應用，最後只能被迫放棄學習。為提升學生學習簡易性，本研究嘗試將抽象電路圖概念實體化，自製一套簡易直流偏壓電路教具，讓學生達到做中學、學中思，提升學習成效。 相較傳統教具，本自製教學教具不受時間、地點限制，故電子與電機群的學生可以將教具帶著走，無論學生在什麼地方和同儕討論或課後複習，有效提升學生學習行動力。透過做中學、學中思的概念，藉由動手做、練習而吸收，成功將短期記憶轉換為長期記憶，顯著提升學生學習。 本自製教具相較傳統測量儀器有以下大突破： 一、教具成本低（約相差14倍）。 二、教具重量輕（約相差27倍）。 三、教具體積小（約相差13倍）。 四、具有行動力，不受時間、地點限制。

As an electronic engineering teacher for many years, when teaching the DC bias circuit unit, researcher discoveries that most electrical engineering and electronic engineering group students can’t convert or apply due to the abstract concept of circuit diagrams. As a result, many students have no choice but to give up learning. To improve students' learning simplicity, researcher makes a simple DC bias circuit teaching box to materialize the concept of abstract circuit diagrams, so that students can achieve and improve their learning effectiveness by doing and thinking by learning. Compared with traditional teaching aids, this self-devised teaching box is free from time limits and location restrictions, so students can carry the teaching box with them no matter where they discuss with their peers or review after-school. It effectively improves students learning motivation. Owing to learning by doing, thinking by learning, students can absorb and convert short-term memory into long-term memory through DIY and practice. The self-devised teaching box significantly improves students’ learning. Compared with traditional measuring instruments, the self-devised teaching box has the following big breakthrough: 1. It costs down (about 14 times the price). 2. It is lighter (about 27 times the weight). 3. It is smaller (about 13 times the volume). 4. It is mobile, free from time limits and location restrictions.
