The quantitative evaluation of experimental data and their graphical presentation are integral to teaching and research in chemistry and the life sciences. Data are commonly fitted to physical models, which in all but the simplest cases are expressed as nonlinear mathematical functions. To facilitate data evaluation in both teaching and research…

LAK-18, the 8th International Conference on Learning Analytics and Knowledge, was hosted by the University of Sydney, Australia, from March 5 to 9, 2018. Traditionally, authors of papers that have received high scores through the review process of the conference are invited to extend their paper and submit it for a special issue of this journal.…

Special education researchers have indicated the need for an increased use of mixed methods research to address many of the complex issues in the field. An important first step in designing mixed methods research is to develop quality research questions. The aim of this article is to provide fundamental information on the formation of mixed…

We provide an overview of ways to involve undergraduate business and retailing students in faculty research projects and discuss advantages of these student-faculty collaborations. We use Kolb's experiential learning cycle to provide a framework for creating an effective and engaging undergraduate research experience and use it to classify types…

Purpose: Repeated duration data are frequently used in behavioral studies. Classical linear or log-linear mixed models are often inadequate to analyze such data, because they usually consist of nonnegative and skew-distributed variables. Therefore, we recommend use of a statistical methodology specific to duration data. Method: We propose a…

A critical issue in educational evaluation is whether evaluations should focus on standardized (summative, often quantitative) or contextualized (formative or often qualitative) evidence. The author of this article advises readers to beware of false dichotomies. The big issue is not whether evaluations should be "standardized" or…

Response time variability and its changes over time have been interpreted as indicative of levels of knowledge automatization. Predominantly, only declines in variability have been examined over the course of practice and growing second language proficiency. We discuss possible scenarios that may involve increasing, rather than declining…

With the growing centrality of digital recording technologies to conversation analysis (CA) research, an emerging array of publications has begun to provide useful methodological insights on how to capture multimodal and temporal complexities of social interaction in video footages. By and large, however, they have been written as general…

Community college transfer students encounter challenges progressing toward a bachelor's degree, leading to widespread transfer credit loss. This in turn may lower students' chances of credential completion and increase the time and costs for students, their families, and taxpayers. In this study we review three definitions of credit transfer…

This quantitative study investigated Kindergarten, 1st grade, and 2nd grade teachers' perceptions regarding using assessment data to support reading development. Thirty-nine teachers from eight southwestern school districts encompassing four counties were surveyed. The researcher used The Statewide Data-Driven Readiness Study: Teacher Survey…

This Special Report -- drawing on insights from a technical working group of experts in arts education, state data systems and state policy -- offers guidance on key arts-education metrics many states could track by using data they already collect.

Adult education has a rich history in Iowa of providing services that assist adults in improving their skills, achieving their educational goals, and transitioning to further education or employment. Instruction is designed for adults functioning at the lowest levels of basic skills and/or needing English language instruction to advance their…

Sharing and integrating data across the variety of public systems, including public health insurance, child care subsidies, and food assistance, accessed by children and families is crucial to providing decision-makers with complete and accurate information that they can use to shape and improve services. This brief highlights projects implemented…

Modern computing technology makes it possible for governments at all levels to use the data they already collect to improve service coordination and delivery, and to conduct research and evaluation to inform policymaking. California is well behind other states in taking advantage of this opportunity, in education and in other fields. The state has…

This paper addresses the question of identifying a concept dependency graph for a MOOC through unsupervised analysis of lecture transcripts. The problem is important: extracting a concept graph is the first step in helping students with varying preparation to understand course material. The problem is challenging: instructors are unaware of the…
