Manipulatives have the potential to be powerful tools in helping children improve their number sense, develop advanced mathematical strategies, and build an understanding of the base ten number system. Physical manipulatives used in classrooms, however, are often not designed to promote efficient strategy use, such as counting on, and typically do…

The purpose of this study was to evaluate two alternative programs in a North Carolina and South Carolina (SC) public school district to determine if they are effective in delivering constructive interventions that modify student behavior once students have left the programs and have returned to their regular learning environments. This…

Educational Badges are touted as an alternative assessment that can increase learner motivation. We considered two distinct models for educational badges; merit badges and videogame achievements. To begin unpacking the relationship between badges and motivation, we conducted a study using badges within an intelligent-tutor system for teaching…

Beginning mathematics teachers enter their classrooms with a network of conceptions about mathematics and how they will go about teaching it. These conceptions are based on a set of beliefs and body of mathematical knowledge. They are robust and deeply ingrained, and they influence how teachers approach the teaching and learning of mathematics.…

The aim of this article is to present an analysis of formal educational documents in the context of the sustainable development notion. This goal was realised by an analysis of the National Curriculum Framework documents from 2002 in comparison with the newest document from 2008. In addition, seven teaching programmes were analysed. On the grounds…

In recent years there has been increasing pressure on PK-12 building level administrators to become more directly involved in classroom instructional practices. The purpose of this study was to examine elements that impacted the teaching building level PK-12 administrator. The study explored potential impediments that prevented a building level…

Recently, there has been an increasing interest in collegiate mathematics education, especially teaching and learning calculus (e.g., Oehrtman, Carlson, & Thompson, 2008; Speer, Smith, & Horvath, 2010). Of many calculus concepts, the derivative is known as a difficult concept for students to understand because it involves various concepts…

This study examines the effect of the translation of traditional scientific vocabulary into plain English, a process referred to as Anglicization, on student learning in the context of introductory microbiology instruction. Data from Anglicized and Classical-vocabulary lab sections were collected. Data included exam scores as well as pre and…

The development of quality educational programs, designed to meet the needs of all students, is a pivotal responsibility of educators and yet a considerable challenge due to the diverse needs in each school. Many consider the Response to Intervention (RtI) model to be one initiative with the greatest potential to improve education for all students…

Although several different types of reading interventions have the potential to produce improved fluency for struggling readers, few studies have directly compared the relative effects of various approaches. The purpose of this study was twofold: (1) to determine the relative effects of word-oriented, fluency-oriented, comprehension-oriented, and…

Riley's Stuttering Severity Instrument (SSI) is widely used. The manuals allow SSI assessments to be made in different ways (e.g. from digital recordings or whilst listening to speech live). Digital recordings allow segments to be selected and listened to, whereas the entire recording has to be judged when listened to live. Comparison was made…

Many weather forecast providers believe that forecast uncertainty in the form of the worst-case scenario would be useful for general public end users. We tested this suggestion in 4 studies using realistic weather-related decision tasks involving high winds and low temperatures. College undergraduates, given the statistical equivalent of the…

There have been many discussions of how Type I errors should be controlled when many hypotheses are tested (e.g., all possible comparisons of means, correlations, proportions, the coefficients in hierarchical models, etc.). By and large, researchers have adopted familywise (FWER) control, though this practice certainly is not universal. Familywise…

The purposes of this study were to associate age-related performance deficits in children with the use of recall strategies and to determine whether children who performed poorly in cycling would benefit from learning a recall strategy. In Experiment 1, 18 younger children (ages 5-7 years) and 18 older children (ages 8-10 years) were asked to…

This article describes a simulation activity that can be used to help students see that the estimator "S" is a biased estimator of [sigma]. The activity can be implemented using either a statistical package such as R, Minitab, or a Web applet. In the activity, the students investigate and compare the bias of "S" when sampling from different…
