Metacognitive learning strategies are based on instructional learning theory, which promotes deep, meaningful learning. Educators in a baccalaureate-level nuclear medicine technology program demonstrated that students enrolled in an online, distance learning section of an introductory radiation protection and radiobiology course performed better when traditional instruction was supplemented with nontraditional metacognitive learning strategies.
The metacognitive learning strategy that was used is best known as concept mapping. The concept map, in addition to the standard homework problem assignment and opportunity for question-answer sessions, became the template for misconception identification and remediation interactions between the instructor and the student. The control group relied on traditional homework problems and question-answer sessions alone. Because students in both the "treatment" groups (i.e., students who used concept mapping) and the control group were distance learning students, all personal communications were conducted via e-mail or telephone. The final examination of the course was used to facilitate a quantitative comparison of the performance of students who used concept mapping and the performance of students who did not use concept mapping.
The results demonstrated a significantly higher median final examination score for the concept mapping group than for the non-concept mapping group (z = -2.0381, P = 0.0415), with an appropriately large effect size (2.65).
Concept mapping is a cognitive learning intervention that effectively enables meaningful learning and is suitable for use in the independent learner-oriented distance learning environments used by some nuclear medicine technology programs.
元认知学习策略基于教学学习理论,该理论促进深入、有意义的学习。一个学士学位水平的核医学技术项目中的教育工作者表明,在传统教学辅以非传统元认知学习策略时,参加辐射防护与放射生物学入门课程在线远程学习部分的学生表现更好。
所使用的元认知学习策略最为人所知的是概念图。除了标准的作业问题布置和问答环节外,概念图成为了教师与学生之间识别误解和进行补救互动的模板。对照组仅依赖传统的作业问题和问答环节。由于“实验组”(即使用概念图的学生)和对照组的学生都是远程学习学生,所有个人交流均通过电子邮件或电话进行。该课程的期末考试用于对使用概念图的学生和未使用概念图的学生的表现进行定量比较。
结果表明,概念图组的期末考试中位数成绩显著高于非概念图组(z = -2.0381,P = 0.0415),效应量适中(2.65)。
概念图是一种认知学习干预手段,能有效促进有意义的学习,适用于一些核医学技术项目所采用的以自主学习者为导向的远程学习环境。
