Two groups of adolescents with learning difficulties in mathematics were compared on their ability to generate solutions to a contextualized problem after being taught problem-solving skills under two conditions, one involving standard word problems, the other involving a contextualized problem on videodisc. All problems focused on adding and subtracting fractions in relation to money and linear measurement. Both groups of students improved their performance on solving word problems, but students in the contextualized problem group did significantly better on the contextualized problem posttest and were able to use their skills in two transfer tasks that followed instruction.
对两组有数学学习困难的青少年进行了比较,比较他们在两种条件下学习解决问题技能后,生成情境化问题解决方案的能力。一种条件涉及标准文字问题,另一种条件涉及光盘上的情境化问题。所有问题都集中在与金钱和线性测量相关的分数加减法上。两组学生在解决文字问题上的表现都有所提高,但情境化问题组的学生在情境化问题后测中的表现明显更好,并且能够在后续指导的两项迁移任务中运用他们的技能。
