Regional Educational Laboratory Southeast, 2021
Broward County Public Schools (BCPS) has identified low student achievement in statistics in the middle grades as a critical concern. It has also expressed concern that statistics instruction does not meet the level of cognitive complexity described in the state curriculum standards. This randomized controlled trial in 40 BCPS middle schools…

Schloemer, Cathy G. – Mathematics Teacher, 2016
Whether students are beginning their study of probability or are well into it, distinctions between complementary sets and mutually exclusive sets can be confusing. Cathy Schloemer writes in this article that for years she used typical classroom examples but was not happy with the student engagement or the level of understanding they produced.…

Wind, Stefanie A. – Educational Measurement: Issues and Practice, 2017
Mokken scale analysis (MSA) is a probabilistic-nonparametric approach to item response theory (IRT) that can be used to evaluate fundamental measurement properties with less strict assumptions than parametric IRT models. This instructional module provides an introduction to MSA as a probabilistic-nonparametric framework in which to explore…

Lawton, Leigh – Journal of Statistics Education, 2009
Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don't calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a…

Goetz, Albert – Mathematics Teacher, 2005
A discussion on the use of group question on final exams is presented to approach work units on probability or counting. Where it is easy to find problems that are both nonroutine and will stretch students minds a bit. The group question is also the fist part of the exam, which involves preliminary discussion and planning, division of labor, and…

Akers, Joan; And Others – Journal of Mathematical Behavior, 1987
Described is a unit, SAMPLING, which focuses on developing student understanding of probability and data collection for junior high school students. Activities in SAMPLING incorporate physical materials, simple computer simulations, surveys of subjective data, computer simulations of complex situations, and a culminating activity requiring the…

Abrahamson, Dor; Janusz, Ruth M.; Wilensky, Uri – Journal of Statistics Education, 2006
ProbLab is a probability-and-statistics unit developed at the Center for Connected Learning and Computer-Based Modeling, Northwestern University. Students analyze the combinatorial space of the 9-block, a 3-by-3 grid of squares, in which each square can be either green or blue. All 512 possible 9-blocks are constructed and assembled in a "bar…
