COMPUTER-ASSISTED TEACHING AND LEARNING OF COTTON CARDING

The emergence of computers in the 1960s and their use in schools and universities opened new doors for modern methods of education. Computers and computer-based technologies have changed the traditional method of teaching, the so-called “chalk and talk” method. From a teacher-centered method in which the teacher delivers information, the use of computers in instruction has made a shift towards student-centered methods in which the teacher facilitates student learning. Through the use of multimedia educational tools, such as animation, video and simulation and network-based Learning Management Systems, such as Blackboard, Moodle, OLAT, Desire2Learn a. s. o., the computer-assisted teaching and learning can improve student satisfaction and academic outcomes. Multimedia technologies make the learning environment more interactive, increase student engagement and motivation to learn, and assist students to develop a better understanding of the topics they are learning. In this paper some interactive tools meant for computer-assisted teaching and learning of cotton carding have been designed, such as schematic drawing of cotton card, animation, video, and assessment tests. The topic is taught to the 3rd year students of the Faculty of Textiles, Leather and Industrial Management from Iasi, the “Technology and Design of Textile Products” specialization. The schematic drawing of cotton card has been created using AutoCAD software, and the video have been recorded with the aid of a Nikon D 5100 digital camera. A free online animated GIF Maker has been used to create an animation view of cotton carding process. In order to create the assessment tests Hot Potatoes software has been used.

20世纪60年代计算机的问世及其在各级学校与高等院校中的应用，为现代教育方法打开了全新的发展空间。计算机及基于计算机的技术已然革新了传统的“粉笔讲授式”（chalk and talk）教学模式。此前以教师为中心、由教师单向传递知识的授课范式，在计算机引入教学后，逐步转向以学生为中心、教师辅助学生自主学习的教学范式。借助动画、视频、仿真等多媒体教学工具，以及Blackboard、Moodle、OLAT、Desire2Learn等网络型学习管理系统（Learning Management Systems, LMS），计算机辅助教与学（Computer-Assisted Teaching and Learning）可有效提升学生的学习满意度与学业成果。多媒体技术能够打造更具交互性的学习环境，提升学生的学习参与度与学习动机，助力学生更深入地理解所学课程内容。

本文针对棉纺梳棉工序的计算机辅助教与学，设计了多款交互式教学工具，包括梳棉机原理图、动画演示、教学视频以及测评试题。该教学内容面向罗马尼亚雅西纺织、皮革与工业管理学院三年级“纺织产品技术与设计”专业的学生。梳棉机原理图采用AutoCAD软件绘制，教学视频依托尼康D 5100数码相机录制完成。本文使用一款免费在线GIF动画制作工具，生成了棉纺梳棉工序的动画演示画面；测评试题的制作则借助了Hot Potatoes软件。
