现代心理科学研究表明,人从听觉获得的知识能够记忆15％,从视觉获得的知识能够记忆25％,视、听并用获得的知识能够记忆65％。当前,现代教学技术还没有普遍运用,用粉笔板书(板画),将文字和图画诉诸于学生视觉,与讲述、演示相辅相成,可以提高教学效果。板书(板画)是教学的重要手段和方法。但是,目前仍有相当数量的教师板书(板画)基本功较差,弊病甚多,严重影响教学效果,有碍于教学卫生,甚至损害师生的健康。因而,有必要对板书“病例”进行“诊断”,加以“治疗”。一、板书“差”。主要“症状”:握笔姿势不对,力度轻重不当,板画粗细不匀,粉迹深淡悬殊,横不平竖不直,书写狂怪潦草,写错用手涂抹,擦黑板粉末飞扬。板书技能很差,影响教学效果。
Modern psychosocial research shows that people get 15% of the knowledge they get from hearing, 25% of what they get from vision, and 65% of their knowledge of what they learn and listen to. At present, the modern teaching technology is not yet widely used. With chalkboard (board drawing), reciting words and pictures to students' visuals, and teaching and demonstrating complement each other, it can improve the teaching effect. Blackboard (board drawing) is an important teaching method and method. However, there are still a large number of teachers' board-writing (board drawing) which have poor basic skills and many drawbacks. They seriously affect their teaching effectiveness, impede the teaching of hygiene and even impair the health of teachers and students. Therefore, it is necessary to “diagnose” the “case” of the blackboard and to “treat” it. First, the blackboard “bad.” The main “symptoms”: not holding the pen posture, the intensity of improper, uneven thickness of the board, pale pinky disproportion, vertical and horizontal not straight, writing scrawl, write the wrong hand smear blackboard powder flying. Bad board skills, affecting teaching effectiveness.
