布卢姆的教育目标分类与掌握学习理论已被大多数教师所接受。其中的目标分类、目标评价及反馈矫正等思想,对中下等生的转化和提高,大面积提高教学质量起到了积极作用。布卢姆认为:有效的教学始于知道希望达到的目标是什么。这就是说教师从事教学活动必须首先有明确的教学目标。教学目标是指教学活动中师生预期达到的结果和标准,它贯穿于教学活动的全过程,制约教学活动的每个环节。本人在初中化学 Bloom's educational goal classification and mastery of learning theory has been accepted by most teachers. Among them, the target classification, target evaluation and feedback correction have played a positive role in transforming and improving lower middle school students and improving teaching quality on a large scale. Bloom believes that effective teaching begins by knowing what it is you want to achieve. This means that teachers must engage in teaching activities must have a clear teaching goal. Teaching objectives refer to the expected results and standards of teachers and students in teaching activities, which runs through the whole process of teaching activities and restricts every aspect of teaching activities.
