Intelligent tutoring systems for ill-defined domains, such as reading and writing, are critically needed, yet uncommon. Two such systems, the Interactive Strategy Training for Active Reading and Thinking (iSTART) and Writing Pal (W-Pal) use natural language processing (NLP) to assess learners' written (i.e., typed) responses and provide immediate,…

In this paper, we investigate two purported problems with Bayesian Knowledge Tracing (BKT), a popular statistical model of student learning: "identifiability" and "semantic model degeneracy." In 2007, Beck and Chang stated that BKT is susceptible to an "identifiability problem"--various models with different…

What are the common types of social goals endorsed by early adolescents and how are they related to their school adjustment? This article discusses the importance of assessing students' social goals during the early adolescent developmental period when peers become increasingly important and youth experience tremendous changes to the school…

In this chapter, we address several questions. How do the prior beliefs of students influence the way in which they process this information? Will students comprehend information with more or less success if it matches or does not match their prior beliefs? Under what circumstances might students change their beliefs? Do students change beliefs to…

In the present chapter, we review the evidence for several principles that are especially promising for improving mathematics instruction. Using the classification scheme proposed by Koedinger et al. (2013), we begin with principles that focus on improving memory and fluency: scaffolding, distributed practice, and feedback. We then move to worked…

Young children who enter school without sufficient social and emotional learning (SEL) skills may have a hard time learning. Yet early childhood educators say they don't get enough training to effectively help children develop such skills. In this article, Megan McClelland, Shauna Tominey, Sara Schmitt, and Robert Duncan examine the theory and…

This article is a follow-up to a previous Journal of Physical Education, Recreation, and Dance Viewpoint article ("The Physical Activity Movement and the Definition of Physical Education"), wherein the authors challenged the oft-cited distinction between physical education and physical activity, and proposed an alternate definition of…

In the United States, educational thought leaders have called for higher expectations (Gordon Commission, 2010), more rigorous college and career readiness standards for K-12 education (National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010), and new constructs such as 21st century skills…

In general, African American males lag behind their White counterparts with regards to high school graduation, college completion and beyond. African American males residing in low resourced communities are especially vulnerable for such disadvantage. Existing literature suggests that parental factors and interactions can help to promote youth…

The status exchange hypothesis suggests that partners in black/white marriages in the U.S. trade racial for educational status, indicating strong hierarchical barriers between racial groups. We examine trends in status exchange in black/white marriages and cohabitations between 1980 and 2010, a period over which these unions have increased from…

Biased sampling occurs frequently in economics, epidemiology, and medical studies either by design or due to data collecting mechanism. Failing to take into account the sampling bias usually leads to incorrect inference. We propose a unified estimation procedure and a computationally fast resampling method to make statistical inference for…

Large-scale assessments are supported by a large item pool. An important task in test development is to assign items into scales that measure different characteristics of individuals, and a popular approach is cluster analysis of items. Classical methods in cluster analysis, such as the hierarchical clustering, K-means method, and latent-class…

Recurrent event data arise frequently in various fields such as biomedical sciences, public health, engineering, and social sciences. In many instances, the observation of the recurrent event process can be stopped by the occurrence of a correlated failure event, such as treatment failure and death. In this article, we propose a joint scale-change…

The scientific rigor of education research has improved dramatically since the year 2000. Much of the credit for this improvement is deserved by Institute of Education Sciences (IES) policies that helped create a demand for rigorous research; increased human capital capacity to carry out such work; provided funding for the work itself; and…

Mathematical discussions in which students compare alternative solutions to a problem can be powerful modes for students to engage and refine their misconceptions into conceptual understanding, as well as to develop understanding of the mathematics underlying common algorithms. At the same time, these discussions are challenging to lead…
