Assessing students' conceptual understanding using an online three‐tier diagnostic test

When solving a mathematical problem, students who do not have sufficient conceptual understanding may perform poorly and exhibit misconceptions. This study was aimed to examine students' conceptual understanding and significant misconceptions when solving number sense‐related problems. An online three‐tier diagnostic test was administered to 125 fifth‐grade students with varied socio‐economic backgrounds in Hong Kong. Only 14.40% of the students exhibited high performance with high confidence, indicating that these students had a profound conceptual understanding of number sense. In addition, the majority of the students (66.40%) did not demonstrate number sense; these students exhibited several significant misconceptions and could solve the questions only by using a rule‐based method or guessing. Accordingly, most students performed unsatisfactorily on number sense‐related problems. This study is imperative in identifying early predictors and provides information for further compatible interventions in the teaching and learning of number sense in Hong Kong in particular and worldwide in general.

生物学教学中"迷思概念"产生原因及对策研究

学生头脑中存在的与科学概念不一致的认识称为“迷思概念”(Misconception),在国外也有称之为先前概念(Precon-ception)、直觉概念(Intuition)、另有概念(Alternative conception)等。建构主义(Constructivism)理论认为,学习不是知识由教师向学生的传递,而是学生建构自己的知识的过程。在这个过程中,可能会因为学习者已有经验或知识的不同,也可能是所接受的信息的来源和方式不同而形成对同一知识的不同理解,甚至是不正确或者错误的理解,而形成“迷思概念”(Misconception)。本文就迷思概念的概念界定、成因分析及教师教学建议展开阐述,并例举部分案例,以期在教学活动中规避或减少迷思概念。

The application of Simulation‐Assisted Learning Statistics (SALS) for correcting misconceptions and improving understanding of correlation

Simulation‐based computer assisted learning (CAL) is recommended to help students understand important statistical concepts, although the current systems are still far from ideal. Simulation‐Assisted Learning Statistics (SALS) is a simulation‐based CAL that is developed with a learning model that is based on cognitive conflict theory to correct misconceptions and enhance understanding of correlation. In this study, a mixed method (embedded experiment model) was utilized to examine the effects of SALS‐based learning compared with lecture‐based learning. The sample was composed of 72 grade‐12 students, who were randomly assigned to either the experimental group or the comparison group. The findings reveal that the SALS‐based learning approach is significantly more effective than lecture‐based learning, in terms of correcting students' misconceptions and improving their understanding of correlation. The study also uses quantitative and qualitative data to examine how the learning model of the SALS‐based learning approach contributes to the enhanced learning outcomes. Finally, practical suggestions were made with regard to directions for future studies.
