Using Monte Carlo simulations, this research examined the performance of four missing data methods in SEM under different multivariate distributional conditions. The effects of four independent variables (sample size, missing proportion, distribution shape, and factor loading magnitude) were investigated on six outcome variables: convergence rate,…

This paper presents an in-depth empirical analysis of a nine-week MOOC. This analysis provides novel results regarding participants' profiles and use of built-in and external social tools. The results served to detect seven participants' patterns and conclude that the forum was the social tool preferred to contribute to the MOOC.

Determining the number of dimensions underlying many variables in the data or many items in the test is a crucial process prior to performing exploratory factor analysis. Failure to do so leads to serious consequences concerning construct validity. Parallel analysis (PA) has been found to be useful to determine the number of dimensions (i.e.,…

Learners are increasingly accessing free online and open resources, tools, and spaces where they can develop their language skills beyond the classroom, alone, or in collaboration with others, and often whilst engaging in purposeful and enjoyable activities. Teachers need to find ways to explore and connect these activities productively with the…

In the last decade, engineering education has evolved in many ways to meet society demands. Universities offer more flexible curricula and put a lot of effort on the acquisition of professional engineering skills by the students. In many universities, the courses in the first years of different engineering degrees share program and objectives,…

In this article, the author describes ten nonfiction books she recommends for adults: (1) "My Reading Life" (Pat Conroy); (2) "Nothing to Envy: Ordinary Lives in North Korea" (Barbara Demick); (3) "Learning to Die in Miami: Confessions of a Refuge Boy" (Carlos Eire); (4) "The Perfect Shape + The Perfect Sauce =…

These proceedings contain the papers of the 10th International Conference on Mobile Learning 2014, which was organised by the International Association for Development of the Information Society, in Madrid, Spain, February 28-March 2, 2014. The Mobile Learning 2014 International Conference seeks to provide a forum for the presentation and…

Mars has been a popular image with students, particularly because of the idea of Martians. This document presents lesson ideas and provides support for teachers on information concerning Mars. (YDS)

This volume offers a comprehensive, up-to-date, empirical and methodological view over the new scenarios and environments for language teaching and learning recently emerged (e.g. blended learning, e-learning, ubiquitous learning, social learning, autonomous learning or lifelong learning), and also over some of the new approaches to language…

Demonstrates a model system that recreates seasonal processes on Mars. Lists necessary materials and explains the construction of the demonstration. Provides discussion questions. (Contains 11 references.) (YDS)

Points out that in 2001, Mars will be closer than usual to Earth and recommends implementing a Marswatch 2001 project in the astronomy curriculum to inspire students. Includes information on available resources and explains the focus points of the activities. (YDS)

Presents a novel approach to teaching astronomy and planetary sciences centered on visual images and simulations of planetary objects. Focuses on the study of the moon and the planet Mars by means of observations, interpretation, and comparison to planet Earth. (Contains 22 references.) (Author/YDS)

This article proposes a new approach to the statistical analysis of pairwisepresent covariance structure data. The estimator is based on maximizing the complete data likelihood function, and the associated test statistic and standard errors are corrected for misspecification using Satorra-Bentler corrections. A Monte Carlo study was conducted to…

The National Aeronautics and Space Administration (NASA) has produced a distance learning series of four 60-minute video programs with an accompanying Web site and companion teacher guides. The story lines of each program or episode involve six inquisitive school children who meet in a treehouse. They seek the solution of a particular problem, and…

Questions about student diversity are examined by considering the extent to which society serves the interests of all, and by examining the empowerment of members of oppressed groups to direct social change. The contributions of multicultural education to empowering young people are highlighted. After an introduction by Christine E. Sleeter, the…
