Abstract: With the transformation and upgrading of the jewelry industry, the jewelry detection industry, as an important link in the industrial chain, is developing from traditional to digital. However, there are some problems in current teaching, such as teaching objectives, teaching resources construction, teaching organization implementation and evaluation, and other aspects. It solidifies the experience of first-line jewelry testing in the way of “data + model”, and conducts the information teaching reform from “teacher teaching” to “digital inheritance”. By independently developing a visual multi-dimensional information intelligent teaching system, setting a scientific and reasonable multiple evaluation system, and carrying out the practice of precise teaching mode of jewelry detection type of courses, the application value of precision teaching driven by big data in the field of jewelry vocational education is highlighted.

如今,大數据、互联网技术的飞速发展正驱动着课堂教学模式的改革,使教学设计、教学实施及考核方式向智慧型转变。而精准教学在珠宝检测类课程的改革与应用还尚未成熟,与目前中国特色高水平高等职业教育学校(以下简称高职)和专业建设要求还有一定的差距。在大数据背景下,教师充分利用互联网、大数据等计算机技术与教育的跨界融合,借助高效的大数据采集、处理与分析[1],能够使珠宝检测类教学更高效且更精准。
1 珠宝检测专业人才培养的现状与问题
珠宝检测涉及物理、化学、宝石学、地质学、矿物学等多门学科的内容(主要内容如图1所示),教学具备较强实践性,要求通过实操训练使学生具备未知样品鉴定的能力,但在实际教学过程中存在以下问题:
1.1 教学目标定位问题
珠宝检测类课程的教学目标存在定位模糊、知识与技能错位的问题。……
