In order to shed more light on why referred girls are less likely to be diagnosed with autism spectrum disorder than boys, this study examined whether behavioral characteristics influence the probability of an autism spectrum disorder diagnosis differently in girls versus boys derived from a multicenter sample of consecutively referred children…

This study analyzes the effect of age-based retention on school achievement at different stages of education. I estimate an instrumental variable model, using the predicted probability of retention given month of birth as an instrument, while simultaneously accounting for the effect of month of birth on maturity at the time of testing. The…

In 2015, 35 million learners participated online in 4,200 MOOCs organized by over 500 universities. Learning designers orchestrate MOOC content to engage learners at scale and retain interest by carefully mixing videos, lectures, readings, quizzes, and discussions. Universally, far fewer people actually participate in MOOCs than originally sign up…

The article presents the findings on students' reasons for studying mechanical engineering. These reasons were covered in terms of extrinsic and intrinsic motivation additionally related to selected independent variables of the sample--students' secondary school Grade Point Average, their gender and the socio-economic status. The research was…

The acquisition of digital skills, media diet management, and general knowledge of ICT, is essential for the development and empowerment of audiences in the current media ecology, particularly considering the political and social challenges of the Latin American environment. In that sense, the study of media competence is urgent for sizing up the…

The purpose of this mixed-method research study was to better understand community college students' engagement in global learning. The study, supported by the Florida Consortium for International Education, was conducted during the 2015-2016 academic year in Florida across nine community colleges drawing from a 55-question survey with an 11%…

A fundamental aspect of statistical inference is representation of real-world data using statistical models. This article analyzes students' articulations of statistical models and modeling during their first steps in making informal statistical inferences. An integrated modeling approach (IMA) was designed and implemented to help students…

The purpose of this study was to determine if the minimum number of observations stated in a district's teacher evaluation plan, observation characteristics described in a district's evaluation plan, and the characteristic of those evaluating teachers had an impact on whether a school would receive a bonus or penalty point for Indiana's A-F…

Undocumented immigrants constitute about 3.5% of the current US population and Texas ranks second, after California, in the number of unauthorized immigrant population. Annually, about 65,000 undocumented children graduate from American high schools. Using the variation provided by the in-state resident tuition policy of Texas, the author…

Hampton (1988) discovered that people are subject to "overextension"--they categorize some things as falling under a conjunction (e.g., they categorize chess as a "sport which is also a game") but not as falling under both of the corresponding conjuncts (e.g., they do not categorize chess as a "sport"). Although…

There is ample evidence that reasoning about stochastic phenomena is often subject to systematic bias even after instruction. Few studies have examined the detailed learning processes involved in learning probability. This paper examines a case study drawn from a large corpus of data collected as part of a research project that dealt with the…

Using data on a large sample of recent Italian graduates, this paper investigates the extent to which participation in study abroad programs during university studies impacts subsequent employment likelihood. To address the problem of endogeneity related to participation in study abroad programs, I use a combination of fixed effects and…

Public pension systems in many U.S. states face large funding shortfalls. Movement toward defined contribution (DC) pension structures may reduce the likelihood of future shortfalls. We address some limitations of the existing literature by studying public-sector employees who are enrolled in either a defined benefit (DB) plan or hybrid DB-DC…

Despite their widespread use, there is little research to support the accuracy of curriculum-based measurement of reading progress monitoring decision rules. The purpose of this study was to investigate the accuracy of a common data point decision rule. This study used a three-point rule with a goal line of 1.50 words read correctly per minute…

Students are faced with many transitions in their middle school mathematics classes. To build knowledge, skills, and confidence in the key areas of algebra and geometry, students often need to practice using numbers and polygons in a variety of contexts. Teachers also want students to explore ideas from probability and statistics. Teachers know…
