【摘要】：当前技能学习者的缺乏，使得职业院校加大了对高级技能学习者的培养进度。而在技能学习过程中，对理论内容以及操作程序的正确记忆成为促进教学进度和预防操作事故的重要保证。研究通过对数控加工专业学习者的错误记忆现象进行较为系统的研究，并结合学生技能学习的现状提出了教学和学习建议。本研究采用实证研究方法，实验材料分为语义关联字词材料、语义关联图片材料、图形材料三种，每种材料均采用DRM范式呈现，对数控加工专业和非数控加工专业共90名学生进行了实验研究。对三种水平（无数控加工技能水平、中级工水平、高级工水平）的数控加工学习者的错误记忆差异并重点对中级工和高级工之间的错误记忆差异进行了统计分析，在此基础上对导致错误记忆差异的原因进行了讨论分析。研究结果表明： 1.三种材料在三种被试上均产生了明显的错误记忆效应，，技能水平的提高，可能导致记忆过程中词语编码的弱化，而图像编码则得到加强，显示出图像编码的优势。 2.非数控专业学习者的字词正确再认率显著的高于高级工学习者的字词正确再认率，这同样表明了高水平的数控专业技能学习者的词语功能弱化现象。 3.对图片材料的再认效果明显的优于对其它两种材料的再认效果，加工水平越高，对材料的学习效果越好。根据研究结果，我们提出如下教学建议：嬉闹理论与技能并重的观念；降低加工样图的关联性；增强加工样图的熟悉度，降低错误率；提高学习材料的加工水平。
[Abstract]:The current lack of skilled learners makes vocational colleges increase the pace of training advanced skill learners. In the process of skill learning, the correct memory of the theory content and the operation procedure becomes the important guarantee to promote the teaching progress and prevent the operation accident. This paper makes a systematic study on the phenomenon of false memory of learners majoring in NC machining, and puts forward some teaching and learning suggestions combined with the present situation of students' skill learning. In this study, the experimental materials are divided into three kinds: semantic associative word material, semantic associative picture material and graphic material. Each material is presented in DRM paradigm. A total of 90 students majoring in NC machining and non-NC machining were studied experimentally. The error memory differences of NC learners at three levels (no NC skill level, intermediate level, advanced level) were analyzed, and the difference of error memory between intermediate and advanced workers was analyzed. On this basis, the causes of error memory differences are discussed and analyzed. The results show that: 1. The three kinds of materials have obvious false memory effect in the three kinds of subjects. The improvement of skill level may lead to the weakening of word coding in the memory process and the enhancement of image coding, which shows the advantage of image coding. 2. The correct recognition rate of non-numerical control major learners is significantly higher than that of advanced technical learners, which also indicates the weakening of word function of advanced NC major learners. 3. The recognition effect of the picture material is better than that of the other two materials. The higher the processing level, the better the learning effect of the material. According to the research results, we put forward the following teaching suggestions: the concept of playing theory and skills equally; reducing the relevance of the processing sample map; enhancing the familiarity of the processing sample map, reducing the error rate; improving the processing level of learning materials.
