微课是当下兴起的重要课程资源,越来越多地运用于各科课堂教学之中,以其灵活、短小、碎片化的特点在“互联网+”时代的发展背景下应运而生。在小学Scratch趣味编程拓展性课程教学中,利用微课开展教学辅助,能够为学生提供自主探究学习的平台,更好地满足不同层次学生的个性化学习需求。笔者从课前微课点迷津、课中微课攻难关和课后微课扣分层等三个层面,借助微课新技术,提升Scratch趣味编程课堂教学的实效性。
Micro-class is an important curriculum resource that is emerging nowadays. It is used more and more in the teaching of all subjects. With its flexible, short and fragmented characteristics, micro-class emerged under the background of the development of “Internet +” era. In primary school Scratch fun programming extension course teaching, the use of micro-class to carry out teaching aids, can provide students with independent inquiry learning platform to better meet the needs of students at different levels of personalized learning. The author improves the effectiveness of Scratch’s fun programming classroom teaching with the aid of micro-class and new technology in the following three aspects: pre-class micro-point learning, micro-class difficulty detection and post-class micro-class deduction.
