The purpose of this study is to demonstrate clustering methods within a functional data analysis (FDA) framework for identifying subgroups of individuals that may be exhibiting categories of misfit. Person response functions (PRFs) estimated within a FDA framework (FDA-PRFs) provide graphical displays that can aid in the identification of persons…

This study reports the use of data mining tools in order to examine the influence of the methodology used in chemistry lab classes, on the weight attributed by the students to the lab work on learning and own motivation. The answer frequency analysis was unable to discriminate the opinions expressed by the respondents according to the type of the…

Background/Context: Over the last two decades, school districts in the United States have increasingly allowed students and their families to choose the schools they attend and, at the high school level, the courses they take. While the movement to provide more curricular choice for students and families has accelerated, so, too, has the policy…

There is much agreement among chemical education researchers that expertise in chemistry depends in part on the ability to coordinate understanding of phenomena on three levels: macroscopic (observable), sub-microscopic (atoms, molecules, and ions) and symbolic (chemical equations, graphs, etc.). We hypothesize this "level-coordination…

In recent years, schools (as well as universities) have added cyber security to their computer science curricula. This topic is still new for most of the current teachers, who would normally have a standard computer science background. Therefore the teachers are trained and then teaching their students what they have just learned. In order to…

This study utilized school-level data from several combined national databases to address two questions regarding school security policy: (1) What are the school characteristics related to levels of security? (2) How does security relate to school suspension, dropout, and college attendance rates? Among the predictors of school security, having a…

Interactive learning environments can provide learners with opportunities to explore rich, real-world problem spaces, but the nature of these problem spaces can make assessing learner progress difficult. Such assessment can be useful for providing formative and summative feedback to the learners, to educators, and to the designers of the…

Many researchers have pointed out that teachers' interpersonal behaviour relates to students' positive attitudes towards schooling. However, only few studies have examined whether students' perceptions of their teachers' interpersonal behaviour relates to students' subject-related attitudes across different school subjects. In this study, it was…

This mixed method study explored and analyzed instructional strategies utilized by algebra teachers whose students' coursework culminated in the New York State Regents Examination in Integrated Algebra and for whom 50% of the tested cohort earned mastery level (85 or higher) on the examination. The targeted populations were eighth or ninth grade…

Every educator's quest is to help students learn in the environment that will allow them to obtain and retain the information presented to them. In the new age of technology, more students are able to choose the environment in which they learn. This study is a quantitative comparative study of the academic performance between online and…

This study aims to improve our understanding of the postsecondary impacts of high schools by investigating whether or not exposure to different high school contexts may explain academic performance once in college. Drawing on a sample of 3,750 participants from the National Longitudinal Survey of Freshmen, descriptive and multivariate analyses…

After a test is developed, most content validation analyses shift from ascertaining domain definition to studying domain representation and relevance because the domain is assumed to be set once a test exists. We present an approach that allows for the examination of alternative domain structures based on extant test items. In our example based on…

The Second International Conference on Educational Data Mining (EDM2009) was held at the University of Cordoba, Spain, on July 1-3, 2009. EDM brings together researchers from computer science, education, psychology, psychometrics, and statistics to analyze large data sets to answer educational research questions. The increase in instrumented…
