Providing ability to probability: Reducing cognitive load through worked‐out examples     

KimberLeigh Felix Hadfield 《Teaching Statistics》2021,43(1):28-35

Undergraduate students tend to struggle with probability in their introductory statistics course. Probability problem solving requires several steps. First, students must make sense of the probability scenario, then determine the appropriate probability rules, and finally, execute the procedures to solve the problem. With no previous exposure to probability, this presents too great a cognitive load for many students. Using worked‐out problems then transitioning to partially worked‐out problems in an introductory statistics course at a large university helped students succeed at solving probability problems. The worked‐out problems included writing prompts to encourage self‐explanation of students' thinking through studying the worked‐out examples. This paper explains the use of these instructional principles and their implementation in an introductory statistics course for non‐STEM majors, resulting in higher student achievement and understanding.  相似文献

中学化学"除去杂质"问题浅议     

王秀玲  王洪义 《邢台学院学报》2003,18(2):91-93

除去杂质是中学化学教学的重点和难点，“除杂”遵循的原则是在除去杂质的过程不能引入新杂质，不能改变被提纯物质的性质、质量，要求被提纯物容易与杂质分离。“除杂”有物理和化学两种方法，利用这些原则和方法简析了有代表性的几个问题。  相似文献   

样例学习研究及其课改意蕴     

王小明 《中学教育》2011,8(2):78-83

样例学习是学习者从例示了一般概念、原理、程序的例子中习得解决问题方法的一种学习方式.和单纯的问题解决学习方式相比,样例学习不仅费时少、迁移效果好,还可减轻学生学习时的认知负荷.早期的样例学习研究集中于数学、物理等学科的单内容样例的学习,最近的研究开始涉及没有明确解题步骤的双内容样例的学习.样例学习的重要机制是学习者对样...  相似文献   

To teach or not to teach the conceptual structure of mathematics? Teachers undervalue the potential of Principle-Oriented explanations     

《Contemporary educational psychology》2019

Principle-oriented explanations have demonstrated to foster students’ mathematical understanding, as they integrate conceptual and procedural information to make the solution process tangible to novice students. Teachers, however, often omit conceptual information when explaining procedures. In two experimental studies, we tested the hypothesis that teachers’ tendency to omit conceptual information may have occurred, as teachers generally devalued the potential of principle-oriented explanations. In Study 1, we randomly provided two cohorts of secondary students (N = 129) with principle-oriented versus procedure-oriented explanations on four mathematical topics. Afterwards, students answered a knowledge test. We replicated previous findings that students with principle-oriented explanations outperformed students with procedure-oriented explanations on the knowledge test (application test, transfer test). In Study 2, we gave mathematics teachers (N = 69) these explanations as judgment materials. Teachers randomly rated a balanced set of four explanations of Study 1 which varied in their procedure- versus principle-orientation. We found no significant differences between teachers’ judgments of principle- versus procedure-oriented explanations. Content analyses of the justifications revealed that teachers were more concerned about students’ overload when judging principle-oriented explanations than procedure-oriented explanations. Our findings replicated the beneficial effects of principle-oriented explanations for novice students’ understanding. Furthermore, they highlight the need to sensitize teachers for potential effects of providing principle-oriented explanations.  相似文献
