Evaluating a web based intelligent tutoring system for mathematics at German lower secondary schools

The present study researches the implementation of a web based intelligent tutoring system for mathematics at lower secondary schools. In recent years, there is growing concern about the worrying situation at German lower secondary schools. Data from large scale educational assessments in the county of North Rhine-Westphalia (NRW) show that children at lower secondary schools have an embarrassing paucity of basic mathematical skills (Leutner et al., Lernstandserhebungen 9. Klasse 2004 in NRW: Erster Kurzbericht zur wissenschaftlichen Begleitung, 2004). In order to improve these basic mathematical skills in lower secondary school children, several schools implemented the web based intelligent tutoring system eFit. The aim of the present research was to investigate whether eFit constitutes an effective intervention of this target group. The results show that compared to a non-treatment control group, children in the eFit group significantly improved their arithmetic performance over a period of 9 months. As will be discussed, the findings have to be treated with cautions because eFit was specifically designed to alleviate mathematical difficulties and therefore “trained for the test” whereas traditional mathematics instruction followed the regular curriculum. The implications of this will be considered in the light of existing theory and research.     

Influences on the Construction of Health News: The Reporting Practices of Local Television News Health Journalists

Local television news remains a primary news source for Americans and is a key source of consumer health information. This study explores why local television health journalists cover particular topics and assesses why health journalism newsgathering practices often differ from the normative newsgathering practices of general assignment reporters. Fifteen in-depth telephone interviews were conducted with health journalists from varying geographical regions and media markets. Influence from local hospitals and personal interest in a health topic often determined the health content the journalists produced. Journalists said it was difficult to cover health issues in addition to other newsroom responsibilities.

The role of spatial ability in mixed reality learning with the HoloLens

The use of mixed reality in science education has been increasing and as such it has become more important to understand how information is learned in these virtual environments. Spatial ability is important in many learning contexts, but especially in neuroanatomy education where learning the locations and spatial relationships between brain regions is paramount. It is currently unclear what role spatial ability plays in mixed reality learning environments, and whether it is different compared to traditional physical environments. To test this, a learning experiment was conducted where students learned neuroanatomy using both mixed reality and a physical plastic model of a brain (N = 27). Spatial ability was assessed and analyzed to determine its effect on performance across the two learning modalities. The results showed that spatial ability facilitated learning in mixed reality (β = 0.21, P = 0.003), but not when using a plastic model (β = 0.08, P = 0.318). A non-significant difference was observed between the modalities in terms of knowledge test performance (d = 0.39, P = 0.052); however, mixed reality was more engaging (d = 0.59, P = 0.005) and learners were more confident in the information they learned compared to using a physical model (d = 0.56, P = 0.007). Overall, these findings suggest that spatial ability is more relevant in virtual learning environments, where the ability to manipulate and interact with an object is diminished or abstracted through a virtual user interface.     

The research and evaluation of serious games: Toward a comprehensive methodology

The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer‐based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social scientific methodology for the evaluation of SGs?; (2) to what extent do SGs contribute to advanced learning?; (3) what factors contribute to or determine this learning?; and (4) to what extent and under what conditions can SG‐based learning be transferred to the real world? In the Netherlands between 2005 and 2012, several hundred SG sessions with 12 SGs were evaluated systematically, uniformly and quantitatively to create a dataset, which comprises data on 2488 respondents in higher education or work organizations. The authors present the research model, the quasi‐experimental design and the evaluation instruments. This focus in this paper is on the methodology and dataset, which form a sound foundation for forthcoming publications on the empirical results.     

Authentically assessing graduate teaching: outside and beyond neo-liberal constructs

In this paper, we challenge the current focus on ‘best practice’, graduate teacher tests, and student test scores as the panacea for ensuring teaching quality and argue for ways of thinking about evidence of quality beginning teaching outside and beyond the current neoliberal accountability discourses circulating in Australia and other countries. We suggest that teacher educators need to reinsert themselves as key players in the debates around quality beginning teaching, rather than being viewed as a source of the problem. To enable teacher educators to assume accountability for quality beginning teachers, we propose the framework of a capstone teacher performance assessment—a structured portfolio called the Authentic Teacher Assessment (ATA)—and examine examples of these assessments through the lens of critical discourse analysis. As a measure of ‘readiness to teach’, the ATA is compared with supervising teachers’ assessments of preservice teachers. We argue that structured portfolios that include artefacts derived from preservice teachers’ practice in classrooms along with graduate teacher self assessments provide a stronger accountability measure of effective beginning teaching and demonstrably address the current anxiety regarding ‘evidence’. We suggest that such an approach should be reliable enough to be ‘read’ by external assessors (and moderated across other teacher education institutions). Rigorous research on a national basis is called for in order to develop and implement a structured portfolio as rich evidence of graduates’ quality and readiness to teach.     

Learning by viewing versus learning by doing: Evidence‐based guidelines for principled learning environments

A learner‐centered approach is a central feature of instruction based on a constructivist learning model. However, there is some confusion regarding the requirement for behavioral activity as a prerequisite for a learner‐centered environment. We offer evidence in this article that some types of behavioral activity can interfere with cognitive learning processes. We recommend that instructional professionals focus on cognitive activity and summarize evidence‐based methods that support appropriate cognitive activity in behaviorally passive and active learning environments.     

Spatial abilities during the circalunar cycle in both sexes

Spatial abilities vary during the menstrual cycle. The effects of a similar rhythm in men are unknown. Mental rotation and spatial visualization of young healthy volunteers (29 females and 31 males) were tested during the menstrual and periovulatory phase of the menstrual cycle in women, and during the low-testosterone and high-testosterone phases of the circatrigintan rhythm in men in random order. Men outperformed women in both tests. In women, higher scores were achieved during the periovulatory phase, in men during the low-testosterone phase. The correlation between actual salivary testosterone levels and spatial abilities were positive in women and negative in men. According to our knowledge, this is the first study showing effects of a male infradian rhythm on cognitive abilities.     

Meeting Needs of Young Children at Risk for or Having a Disability

Poverty-related factors place children at higher risk for disabilities and also serve as barriers to families accessing services for their children and themselves. Early childhood practitioners can play a critical role in supporting families by providing services to overcome these obstacles and by working in partnership with specialized early intervention programs to assure the families and children receive those services. Families (N = 3,001) enrolled in the Early Head Start (EHS) Research and Evaluation Project were randomly assigned to the program group (who received EHS services) or the control group in a rigorous, experimental design study in order to evaluate program impacts. All participating families were living in poverty, included a pregnant woman or a child below age 1, and were eligible for EHS. The majority of children enrolled in the EHS Research and Evaluation Project was identified as having at least one of a great variety of disability indicators (e.g., family received Part C services, child has been diagnosed as having asthma). There was a very small number of families, however, actually enrolled in Part C services. Enrollment in EHS was associated with children being less likely to have cognitive or language delays and their families being more likely to receive early intervention (Part C) services and have Individualized Family Service Plans (IFSPs) when they needed them.     

Moving toward a grand theory of development: in memory of Esther Thelen

This paper is in memory of Esther Thelen, who passed away while President of the Society for Research in Child Development. A survey of Esther Thelen's career reveals a trajectory from early work on simple movements like stepping, to the study of goal-directed reaching, to work on the embodiment of cognition, and, ultimately, to a grand theory of development--dynamic systems theory. Four central concepts emerged during her career: (1) a new emphasis on time; (2) the proposal that behavior is softly assembled from the interaction of multiple subsystems; (3) the embodiment of perception, action, and cognition; and (4) a new respect for individuality. Esther Thelen communicated these ideas to scientists and practitioners alike, so the ultimate benefactors of her work were children.
