根据美国心理学家布鲁姆的研究,学生学习过程中的认知活动从低到高依次可分为六个层次,即识记、理解、应用、分析、综合、评价。为了了解学生掌握知识的层次,可用不同层次的试题对他们的认知水平加以测试。现以生理卫生循环系统中输血和血型这部分内容的一组试题为例加以说明。 According to the study of American psychologist Broome, the cognitive activities in the learning process of students can be divided into six levels in descending order: namely, memorization, understanding, application, analysis, synthesis, and evaluation. In order to understand the level of students’ knowledge, different levels of questions can be used to test their cognitive level. A set of questions on blood transfusion and blood type in the physiological sanitation circulation system will be used as an example.
