在新修订的布卢姆教育目标分类学中,知识是分为四个类别的,即事实性知识、概念性知识、程序性知识及元认知知识,在每个类别下面都有2、3个亚类,如程序性知识中就有三个亚类,算法的知识是其中的一个。算法是由基本运算及规定的运算顺序所构成的完整的解题步骤,它可以看成按照要求设计好的、有限的、确切的计算序列,并且这样的步骤和序列可以解决一类问题。例如在解决“分数的加减”这一类问题时,教师通常会要求学生进行这样的操作步骤:先判断两个分数的分母,如果分母相同,则分子相加减;如果分母不同,先把分母进行通分,然后分子相加减。
In the newly revised Bloom Educational Objectives Taxonomy, knowledge is divided into four categories, namely, factual knowledge, conceptual knowledge, procedural knowledge and metacognitive knowledge, under each category there are 2,3 There are three subcategories of procedural knowledge, one of which is the knowledge of algorithms. The algorithm is a complete solution to the problem posed by the basic operations and the specified order of operations. It can be regarded as a limited and exact calculation sequence designed according to requirements, and such steps and sequences can solve a type of problem. For example, in the case of solving the problems of “addition and subtraction of scores”, the teacher usually requires the student to carry out the steps as follows: judge the denominator of two scores first, and then add and subtract the numerator if the denominator is the same; if the denominator is different, First pass the denominator, and then subtract the numerator.
