[[alternative]]The Application of Tool Offset Cutting Path Simulated Equipment in the Learning Efficiency Study of CNC Lathe Tool Offset Unit in the Mechatronics Department of the Vocational Senior High School

碩士工業教育與技術學系[[abstract]]本研究旨在探討刀具補正車削路徑模擬裝置對高工機電科學生「數值控制機械」科目單元學習成效之影響。本研究分為二階段，第一階段旨在透過「數值控制車床實習」學習困擾調查問卷探討高工機械類科「數值控制機械實習」科目之「數值控制車床刀具補正單元」教學之相關問題與需求，經由分析、構思設計、評估、完成零件與組合圖、製作原型裝置、實測與改進等階段，創製一組「數值控制車床刀具補正車削路徑模擬裝置」。 第二階段旨在透過應用「刀具補正車削路徑模擬裝置」於高工機電科「數值控制車床刀具補正單元」輔助教學，分析其提升教學成效之情形。 本研究採前測-後測之準實驗設計(quasi-experimental research design)。研究工具包括「數值控制機械實習」學習困擾調查問卷、刀具補正車削路徑模擬裝置、學科學習成就前/後測量表、術科學習成就量表、學習態度量表、以及「刀具補正車削路徑模擬裝置」使用滿意度調查問卷七項。本研究實驗組以「刀具補正車削路徑模擬裝置」輔助教學；控制組以傳統教學法進行教學。授課內容以教育部87年公佈新課程標準之課程大綱為依據，發展實驗教學教案，實施為期三週18小時的實驗教學。 在實驗教學前對兩組學生進行學習成就前測量表測驗，其主要目的在瞭解實施實驗教學前兩組學生在「數值控制車床刀具補正」的學習差異。在教學三週後，再對兩組學生實施學習成就後測量表測驗，而實驗組學生增加實施「刀具補正車削路徑模擬裝置」學後調查問卷作學習滿意度調查。 本研究假設考驗採獨立樣本t考驗、共變數分析及描述統計方法，所獲致的結論敘述如下： 壹、高工機械類科「數值控制機械實習」科目，學生學習最感困擾的為：機器設備太少。 貳、「刀具補正車削路徑模擬裝置」可提升「數值控制車床刀具補正單元」學生學習成效。 參、學生對使用「刀具補正車削路徑模擬裝置」輔助教學多持肯定與贊同。[[abstract]]The purpose of this study was to investigate the application of a tool offset cutting path simulated equipment (TOCPSE) to improve the learning effectiveness of the subject unit in the numerical control (NC) machine practice class held in the mechatronics department of the Industrial senior high school (ISHS). This study was classified into two stages: At the first stage, the questionnaire of after learning was taken to explore the relative problems and essential of teaching in the practical class of NC lathe in the mechanical department of ISHS. The TOCPSE in NC lathe was designed under the sequence process: analysis, thinking, design, drafting of the element and composite, prototype, evaluation, and improvement. In the second stage, the TOCPSE was employed to assist the teaching in the unit of tool offset in NC lathe, held in the mechatronics department of ISHS, to evaluate the feasibility of the promotion in learning effectiveness. This study utilized the quasi-experimental design and used the six research tools included the questionnaire of after learning, TOCPSE, the pretest/posttest measurements of learning achievement, the examination of learning efficacy of practical subject, the test of learning altitude, and the survey of after studying. In this study, the experimental group was taught with TOCPSE to assist the learning; in the other hand, the controlled group was trained with the traditional teaching strategy. The experimental course was executed within eighteen hours for three weeks, which was based on the syllabus of the standard new curriculum announced in 1998 by Ministry of Education. Before the experiment, the students of two groups had examined with the pretest of learning performance to analyze the difference in the tool compensated unit of NC lathe. Three weeks later, the posttests of learning achievement of two groups were investigated, and then the questionnaire of learning satisfaction in TOCPSE was added to the students in experimental group. The Independent Sample t test, Two-Way ANOVA and Description Statistics were conducted in this experiment and the conclusions were listed as follows: The great confusion of student’s learning in the class of NC machine practice held in the mechanical department of ISHS is that the NC machine is so deficient. TOCPSE had actually promoted the learning effectiveness and attitude for the student who had utilized it in the tool compensated unit of NC lathe. The most of the students were affirmed and approved the function of TOCPSE in teaching assistance
