This paper describes a student laboratory in the Unit Operations Laboratory at the Colorado School of Mines: air separation by pressure swing adsorption. The flexibility of the system enables students to study the production of enriched nitrogen or oxygen streams. Automatic data acquisition permits the study of cycle steps and performance.…

Some IRT models can be equivalently modeled in alternative frameworks such as logistic regression. Logistic regression can also model time-to-event data, which concerns the probability of an event occurring over time. Using the relation between time-to-event models and logistic regression and the relation between logistic regression and IRT, this…

Background: Deep versus surface knowledge is widely discussed by educational practitioners. A corresponding construct, levels of processing, has received extensive theoretical and empirical attention in learning science and psychology. In both arenas, lower levels of information and shallower levels of processing are predicted and generally…

Purpose: This paper aims to explore the likelihood that face-to-face (FTF) interviewing will continue to be the "gold standard" survey interviewing method, to which all other modes are compared, in an era in which daily communicative habits for many now involve selecting among many alternative modes. Design/methodology/approach: After…

Life sciences research is increasingly international and data-intensive. Researchers work in multi-jurisdictional teams or formally established research consortia to exchange data and conduct research using computation of multiple sources and volumes of data at multiple sites and through multiple pathways. Despite the internationalization and data…

The paper investigates how the order of numerical data in word problems on division of a whole into unequal parts affects achievement and reasoning of 14-16-year old pupils. The variable was altered in two word problems, in one of which also the context was changed (psychological variable) and in the latter "if-clause" is or is not used…

The concept of effect size plays a crucial role in assessment, institutional research, and scholarly inquiry, where it is common with large sample sizes to find small relationships that are statistically significant. This study examines the distribution of effect sizes from institutions that participated in the National Survey of Student…

Background: Domestic violence abuse (DVA) has been identified by the UK Government as a priority to address. Whilst there is a growing body of research into perpetrators of DVA from the mainstream population, there is scant research into perpetrators of DVA who have an intellectual disability. This lack of an evidence base suggests there may be a…

The study aimed at examining the relationship between body image satisfaction and bulimia nervosa among the students of education faculty at king said university students. The author used the tests of bulimia nervosa and body image test. The researcher verified tests reliability. Students from King Saud University randomly selected (No. 337)…

The article raises questions about the use in art education classrooms of social networking sites like Facebook and image sharing sites like YouTube that rely upon the ability of Big Data to aggregate large amounts of data, including data on students. The article also offers suggestions for the responsible use of these sites. Many youth are using…

Searching for information is critical in many situations. In medicine, for instance, careful choice of a diagnostic test can help narrow down the range of plausible diseases that the patient might have. In a probabilistic framework, test selection is often modeled by assuming that people's goal is to reduce uncertainty about possible states of the…

The ability to interact with and properly manage data in a research setting has become increasingly important in all disciplines. Libraries are attempting to identify their role in providing data management services. However, humanities faculty's conceptions of data and their data management practices are not well-known. This qualitative study…

The current study determined growth patterns during an 8-week writing intervention and then examined the association between growth pattern and students' initial skills as determined by instructional-level data. One hundred forty-seven first-grade students struggling with early literacy skills received a writing intervention at one of two tiers of…

The UNESCO Institute for Statistics (UIS) has been measuring ICT in education since 2009, but with such rapid change in technology and its use in education, it is important now to revise the collection mechanisms to focus on how technology is being used to enhance learning and teaching. Sustainable development goal (SDG) 4, for example, moves…

In recent educational reforms, policy papers present students' desire and motivation for learning as decisive issues. The documents indicate that motivation has become a crucial issue for governmental intervention and results in a number of motivational technologies. Envy, once perceived as a mortal sin, is shown as integral of the ambiguous…
