When it comes to technologies like digital games, simulations, and social networking, teachers and students may find themselves at cross purposes. Often, students find that these technologies, so prevalent in their lives outside of school, are unwelcome in their classrooms. Many teachers can tell stories about the disruptive influence of video…

In Ramsay-curve item response theory (RC-IRT), the latent variable distribution is estimated simultaneously with the item parameters of a unidimensional item response model using marginal maximum likelihood estimation. This study evaluates RC-IRT for the three-parameter logistic (3PL) model with comparisons to the normal model and to the empirical…

Tutors have only limited time to support students. In this paper, we discuss a model that addresses the question of how to help students answer content-related questions. A small group of students is created, which consists of the student who asked the question and peers who should be able to answer it. Criteria used to compose the group are the…

Extreme-value statistics is often used to estimate so-called return values (actually related to quantiles) for environmental quantities like wind speed or wave height. A basic method for estimation is the method of block maxima which consists in partitioning observations in blocks, where maxima from each block could be considered independent.…

Over the past several decades, colleges and universities have moved away from the traditional chalk-and-talk lecture. Professors have experimented with a myriad of methods to engage students more fully. Some of the innovations that have been used have succeeded in improving student performance and satisfaction. In this paper we report the learning…

THE PROBLEM: This study investigated students' perceptions of the English Village Program at the Fong Shan Elementary School in Kaohsiung County, Taiwan. The main objectives of this research were to discover the fifth graders' motivation and attitudes toward (a) the simulated theme classrooms, (b) the native English-speaking teacher's instruction,…

Dodeen (2004) studied the correlation between the item parameters of the three-parameter logistic model and two item fit statistics, and found some linear relationships (e.g., a positive correlation between item discrimination parameters and item fit statistics) that have the potential for influencing the work of practitioners who employ item…

This study investigates the extent to which analytic power can be increased through the inclusion of siblings in a data set and the concomitant use of random coefficient multilevel models. Analyses of real-world data regarding the predictors of young adult alcohol use illustrate how parallel single-level analyses of a 1-child-per-family data set…

Gravity is a subtle but ubiquitous force that influences nearly all geologic processes from the formation of ores to the flow of glaciers and rivers. Gravity also determines the path some materials take as they flow down volcanoes. Lava flows, mudflows (also called lahars), and pyroclastic flows are three such materials. Understanding the factors…

The thought of learning about the principles of classical management and the machine metaphor of organizing can get many organizational communication students yawning just by seeing the subject in a syllabus. Abundant movie and television examples associated with the machine-like nature of workplace productivity are often used to demonstrate…

The aim of this activity is to immerse students in a simulated situation where they are enticed to make snap judgments about strangers, demonstrating that they can and easily do, and then motivate them to critically reflect on the consequences that these presumptions have on effective interpersonal communication. This activity allows students to…

Two experiments explored the possibility that individual differences in working memory capacity (WMC) partially reflect differences in the size of the search set from which items are retrieved. High- and low-WMC individuals were tested in delayed (Experiment 1) and continuous distractor (Experiment 2) free recall with varying list lengths. Across…

This article introduces a multinomial error model, which models an examinee's test scores obtained over repeated measurements of an assessment that consists of polytomously scored items. A compound multinomial error model is also introduced for situations in which items are stratified according to content categories and/or prespecified numbers of…

The purpose of this activity was to help students understand the percentage of cloud cover and make more accurate cloud cover observations. Students estimated the percentage of cloud cover represented by simulated clouds and assigned a cloud cover classification to those simulations. (Contains 2 notes and 3 tables.)

Background/Context: Rabbi Raymond Zwerin and Audrey Friedman Marcus published the Gestapo Holocaust simulation game in 1976. Since that time it has been a source of debate among Jewish intellectuals and other scholars concerned with the pedagogy of the Holocaust. Even the United States Holocaust Memorial Museum has weighed in on the issue, taking…
