摘要

本案例研究在2019年冠状病毒病(COVID-19)封锁期间进行,采用在线数据收集手段,根据概率与计数原理(PCP)教师评分,调查流行的12年级在线数学教科书中概率与计数原理(PCP)学习任务的认知需求水平分布。教师的认知需求等级按照Stein的数学任务框架进行分类。来自南非两个省四所中学的五名数学教师通过填写在线问卷参与了这项研究。我们开发了一个评分框架,称为平均认知需求评分(MCDR),以帮助我们解释教师在认知需求方面对学习者的任务感知。来自教师评分的数据显示,在线教科书中近65%的PCP学习任务被评为高。然而,对2014年至2020年基础教育部诊断报告中的二级数据的分析表明,教师对学习任务的评级与学习者的表现之间没有联系。贡献:这项研究引起了人们对概率主题长期表现不佳的关注,并建议以课堂为基础的研究,重点关注学习者对学习任务的评价,以清楚地了解如何最好地支持他们。

Investigating the cognitive demand levels in probability and counting principles learning tasks from an online mathematics textbook
This case study carried out during the 2020 coronavirus disease of 2019 (COVID-19) lockdown used online data collection means to investigate the distribution of cognitive demand levels of probability and counting principles (PCP) learning tasks in a popular online Grade 12 mathematics textbook, based on the PCP teachers’ rating. The teachers’ cognitive demand ratings were categorised following Stein’s mathematical task framework. Five mathematics teachers from four secondary schools in two provinces in South Africa participated in the study by filling in an online questionnaire. We developed a rating framework named the mean cognitive demand rating (MCDR) to help us interpret the teachers’ perception of the tasks in terms of cognitive demand to the learners. Data from the teachers’ ratings revealed nearly 65% of the PCP learning tasks in the online textbook were rated as high. Analysis of secondary data from Department of Basic Education diagnostic reports from 2014 to 2020, however, suggests no association between teachers’ rating of learning tasks and learner performance. Contribution: This study draws attention to a long-standing underperformance in the topic of probability and suggests classroom-based study that focuses on the learners’ rating of the learning tasks themselves to understand clearly how best to support them.

期刊介绍: Pythagoras is a scholarly research journal that provides a forum for the presentation and critical discussion of current research and developments in mathematics education at both national and international level. Pythagoras publishes articles that significantly contribute to our understanding of mathematics teaching, learning and curriculum studies, including reports of research (experiments, case studies, surveys, philosophical and historical studies, etc.), critical analyses of school mathematics curricular and teacher development initiatives, literature reviews, theoretical analyses, exposition of mathematical thinking (mathematical practices) and commentaries on issues relating to the teaching and learning of mathematics at all levels of education.
