题目内容

王老师觉得在信息技术课上采用任务驱动教学法教学效果较好,他给高一2班讲授“图像加工工具”时,在关于金山画王这部分内容的教学环节中,拟采用这种教学法,主要教学过程如下: 王老师首先通过打开各种图片格式文件的示例,给同学们介绍了金山画王的主要特点,使用方法和注意事项: 王老师提出“任务”,请同学们使用金山画王打开计算机中不同格式的图片素材,熟悉金山画王软件。 5分钟后,老师巡视学生的整体情况,发现有不少同学已完成这项任务,其中一些同学还在玩小游戏或做其他事情,他所希望的“热火朝天”的学习景象并未出现,使他觉得这部分内容的教学教案并不如他想象的那样理想。 问题: 针对以上不足,请给王老师提出改进教学的建议。
