Ho and Reardon (2012) present methods for estimating achievement gaps when test scores are coarsened into a small number of ordered categories, preventing fine-grained distinctions between individual scores. They demonstrate that gaps can nonetheless be estimated with minimal bias across a broad range of simulated and real coarsened data…

This manual provides guidance and documentation for users of the kindergarten (or base year) data of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It begins with an overview of the ECLS-K:2011. Subsequent chapters provide details on the study data collection instruments and methods; the direct and indirect…

Starting primary education is one of the most important changes that children encounter in early childhood. Moreover, especially within the last twenty years, as an outcome of the idea that children are active learners, listening to children's ideas about their learning, lives, and experiences has gained importance. In this sense, this study is…

This study examines the feasibility of recruiting and retaining adolescents and young adults with frequent cannabis use for a 2-week momentary sampling study of cannabis use. Participants responded to random signals on a handheld computer with reports of their use. Participants also initiated reports pre- and post-cannabis use. Participants had…

Although the concept of the sampling distribution is at the core of much of what we do in econometrics, it is a concept that is often difficult for students to grasp. The thought process behind bootstrapping provides a way for students to conceptualize the sampling distribution in a way that is intuitive and visual. However, teaching students to…

Large-scale assessment programs such as the National Assessment of Educational Progress (NAEP), Trends in International Mathematics and Science Study (TIMSS), and Programme for International Student Assessment (PISA) use a sophisticated assessment administration design called matrix sampling that minimizes the testing burden on individual…

Many current national and institutional education policies address the issue of raising participation amongst young people and enhancing employability after leaving school or university. What sort of information are these policies built on? This paper compares national information systems from the last three decades across Europe that gather…

The aim of the study is to reveal the students' views who are studying in different departments of distant education programs provided by Anadolu University in Turkey. Qualitative research method was used in the study and purposeful sampling was followed. The research was conducted with 10 students who were working in different jobs and taking…

We explore the use of instrumental variables (IV) analysis with a multisite randomized trial to estimate the effect of a mediating variable on an outcome in cases where it can be assumed that the observed mediator is the only mechanism linking treatment assignment to outcomes, an assumption known in the IV literature as the exclusion restriction.…

This case study describes the research carried out in partial fulfilment of the degree of doctor of education. The study was qualitative in nature with a phenomenological interpretive paradigm. My primary objective is to share my experience of combining life story and grounded theory research. My main objectives for undertaking the research were…

This case study presents an overview of methods used to carry out an exploratory mixed-methods ethnographic study of video bloggers, or vloggers, on YouTube. Vlogs can be used as a multimedia data source for researchers who wish to explore topics such as digital culture or self-expression in social media environments. A combination of online…

School discipline is a core indicator of school effectiveness. Learner management is crucial and educational researchers need to focus on factors leading to indiscipline in schools. Guided by Planned Behaviour Theory that explores on guidance, counseling and good classroom management the study used the survey research design to sample 91 teachers…

A qualitative study was conducted to explore the perception of healthcare professional students about mobile learning acceptance. Method: The study was performed using a conventional content analysis method. The subjects were the students of medical sciences in Iran University of Medical Science. Sampling was based on a purposeful sampling method.…

Exploratory factor analysis involves five key decisions. The second decision, how many factors to retain, is the focus of the current paper. Extracting too many or too few factors often leads to devastating effects on study results. The advantages and disadvantages of the most effective and/or most utilized strategies to determine the number of…

This study investigates a sequence of item response theory (IRT) true score equatings based on various scale transformation approaches and evaluates equating accuracy and consistency over time. The results show that the biases and sample variances for the IRT true score equating (both direct and indirect) are quite small (except for the mean/sigma…
