A glass of water covered with a disk with a hole in it can be turned upside down without spilling the water in the glass, provided the hole is small enough and the disk is pressed against the rim of the glass. A quasistatic numerical simulation based on hydrostatic pressure and surface tension of water was used calculate the critical hole diameter…

The literature shows that unguided device use in the classroom decreases academic outcomes for a broad range of students. However, the literature does not address potential harms to graduate students. We investigate where highly motivated graduate students in a professional MPA program would be vulnerable to the same device distraction effects as…

This article presents the results of a design-based research study related to slope that took place in a high school algebra 1 classroom. In the study, students explored situations related to making predictions. As students engaged with these situations, they reinvented and made meaningful multiple subconstructs of slope. I present the findings in…

This study uses the log data from Moodle learning management system for predicting student learning performance in the first third of a semester. Since the quality of the data has great influence on the accuracy of machine learning, five major data transmission methods are used to enhance data quality of log file in the data preprocessing stage.…

A sizable number of low-income high school graduates enroll in colleges less selective than their academic qualifications would allow or forgo postsecondary altogether despite being college-ready. One potential cause of this "undermatching" is that some students have limited access to information about their college options. We…

Student burnout and Internet addiction are two of the serious problems that are common among young people. Both are connected with many negative effects on the mental functioning of adolescents. However, so far only few studies have explored these two phenomena all together. The aim of our study was to test the relationship between student burnout…

This study examined the factors that influence support for campus carry laws among a sample of approximately 2,700 faculty/administrators, staff, and students at a large, public university in Georgia. Although previous research suggests that support for campus carry may differ across groups on campus, there have been no studies that have examined…

Both educational data mining and learning analytics aim to understand learners and optimise learning processes of educational settings like Moodle, a learning management system (LMS). Analytics in an LMS covers many different aspects: finding students at risk of abandoning a course or identifying students with difficulties before the assessments.…

This special issue consists of 20 articles that focus on issues related to Eisenberg and colleagues' (Eisenberg, Cumberland, & Spinrad, 1998; Eisenberg, Spinrad, & Cumberland, 1998) model of emotion socialization processes and its relevance for understanding a range of aspects of children's socioemotional functioning. The various papers…

This work reports the results of a research aimed to know the probabilistic reasoning of high-school students when they deal with the notion of random intervals. An activity was carried out involving students between ages 16 and 17 who built random intervals through physical and computational simulations. The research question guiding this work…

Theories of discourse argue that comprehension depends on the coherence of the learner's mental representation. Our aim is to create a reliable automated representation to estimate readers' level of comprehension based on different productions, namely self-explanations and answers to open-ended questions. Previous work relied on Cohesion Network…

In colleges, programming is increasingly becoming a general education course of almost all STEM majors as well as some art majors, resulting in an emerging demand for scalable programming education. To support scalable education, teaching activities such as grading and feedback have to be automated. Recently, online judge systems have been…

Effective teachers are those who create a classroom climate which meets the needs of the students (Darling-Hammond, 2009; Hart & Hodsen, 2004). In an attempt to identify preservice teachers who can create this type of classroom, Missouri added a workplace inventory, the Missouri Educator Profile (MEP), to their required battery of teacher…

The first purpose of this study was to examine the prevalence of risk for comorbid reading and mathematics disabilities (RMD) at start of first grade, when measured in a representative sample of 3,062 students with first-grade fluency measures (word reading; computation). The second purpose was to examine the utility of these measures for…

This study examined the relationships among cultural values, goal orientations, and mathematics achievement in mainland China. Structural equation models were used to analyze data on 350 Grade 5 students. The results showed that mathematics achievement was positively related to family-support and mastery goal orientations and negatively related to…
