从目前初三学生化学学习情况看,大多数学生喜欢花大气力记忆教师给出的化学知识,而不善于用自己的头脑去主动获取和保持知识,这样的学习行为会阻碍其自身化学思维能力的发展。为了转化学生的这一不良学习喜好,必须培养和提高学生的化学思维能力。笔者发现:让学生填写或设计优质的表格,不但能驱使他们通过思维活动长久地保持自己所获取的新知,而且能帮助他们将机械记忆的学习方式扭转为探究性学习方式。现以初中化学“元素”的教学为例,谈谈具体做法。
From the current junior high school chemistry learning situation, most students like to spend their time to remember the chemical knowledge given by teachers, but not good at using their own mind to take the initiative to acquire and maintain knowledge, this learning behavior will hinder its own chemical thinking ability development of. In order to transform students’ bad learning preferences, students must be trained in chemistry thinking. The author found that having students fill in or design good forms not only drives them to stay informed of what they have acquired through thoughtful activities but also helps them to reverse the learning of mechanical memory as an inquiry learning. Now junior high school chemistry “element ” teaching, for example, to talk about specific practices.
