tandfonline.com – Students’ Understanding of Bar Graphs and Histograms: Results From the LOCUS Assessments

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Bar graphs and histograms are core statistical tools that are widely used in statistical practice and commonly taught in classrooms. Despite their importance and the instructional time devoted to them, many students demonstrate misunderstandings when asked to read and interpret bar graphs and histograms. Much of the research that has been conducted about these misunderstandings has been with students in introductory statistics classes at the college level. In this article, students in grades 6–12 completed multiple-choice and constructed-response questions about bar graphs and histograms as part of a larger study. The same misunderstandings that college-level students demonstrate were found in these younger students. Link til kilde

tandfonline.com – Does the Model Matter? Exploring the Relationship Between Different Student Achievement-Based Teacher Assessments

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Policymakers have demonstrated an interest in using measures of student achievement to inform high-stakes teacher personnel decisions, but the idea of using student outcomes as a teacher performance measure is complex to implement for a variety of reasons, not least of which is the fact that there is no universally agreed upon statistical methodology for translating student achievement into a measure of teacher performance. In this article, we use statewide data from North Carolina to evaluate different methodologies for translating student test achievement into measures of teacher performance at the elementary level. In particular, we focus on the extent to which there are differences in teacher effect estimates generated from different modeling approaches, and to what extent classroom level… Continue Reading
