Using Student Video Cases to Assess Pre-service Elementary Teachers’ Engineering Teaching Responsiveness

Our study addresses the need for new approaches to prepare novice elementary teachers to teach both science and engineering, and for new tools to measure how well those approaches are working. This in particular would inform the teacher educators of the extent to which novice teachers are developing expertise in facilitating their students’ engineering design work. One important dimension to measure is novice teachers’ abilities to notice the substance of student thinking and to respond in productive ways. This teacher noticing is particularly important in science and engineering education, where students’ initial, idiosyncratic ideas and practices influence the likelihood that particular instructional strategies will help them learn. This paper describes evidence of validity and reliability for the Video Case Diagnosis (VCD) task, a new instrument for measuring pre-service elementary teachers’ engineering teaching responsiveness. To complete the VCD, participants view a 6-min video episode of children solving an engineering design problem, describe in writing what they notice about the students’ science ideas and engineering practices, and propose how a teacher could productively respond to the students. The rubric for scoring VCD responses allowed two independent scorers to achieve inter-rater reliability. Content analysis of the video episode, systematic review of literature on science and engineering practices, and solicitation of external expert educator responses establish content validity for VCD. Field test results with three different participant groups who have different levels of engineering education experience offer evidence of construct validity.     

Beatrix Potter: A Hundred Years in Translation

This year, 2016, marks the 150th anniversary of the birth of Beatrix Potter (1866–1943), the much-loved author and illustrator of children’s books. Although translation has made a vital contribution to her international success, Potter’s work remains relatively under-researched from a translation studies perspective. This article aims to provide a clearer picture of Potter’s work in translation over the last hundred years. It identifies early translated editions and discusses Potter’s involvement in their preparation, before examining the appearance of her stories in translation around the world and outlining particular trends in Potter translation. This study is based on extensive research using numerous databases, Potter’s published biographies and correspondence, and on an analysis of the first French editions of her tales. The study reveals that the first published translations of Potter’s works are both of an earlier date and more numerous than is recognised in existing scholarship. It also shows that Potter’s preferred approach in the translation of her stories into French was to adapt the tales to their new French readership, rather than staying close to the originals. Her works are found to have been extensively translated during the last century, especially into European languages, as well as into a significant number of Asian languages. Other matters discussed include the involvement of Potter’s official publisher, Warne, in the publication of international editions; the existence of translations based on American editions with new illustrations; and the posting of online translations by Potter enthusiasts.     

Associations of Parenting Styles and Dimensions with Academic Achievement in Children and Adolescents: A Meta-analysis

Parents and researchers alike are interested in how to promote children’s academic competence. The present meta-analysis integrates the results of 308 empirical studies on associations of general parenting dimensions and styles with academic achievement of children and adolescents assessed via grade point average or academic achievement tests. Parental responsiveness (warmth), behavioral control, autonomy granting, and an authoritative parenting style were associated with better academic performance both concurrently and in longitudinal studies, although these associations were small in a statistical sense. Parental harsh control, and psychological control, as well as neglectful, authoritarian, and permissive parenting styles were related to lower achievement with small to very small effect sizes. With three exceptions, parenting dimensions and styles also predicted change in academic achievement over time. Moderating effects of child age, ethnicity, reporter on parenting and academic achievement, quality of the parenting and achievement measure, and publication status were identified. It is concluded that associations of academic achievement with general parenting dimensions/styles tend to be smaller than associations of school-specific parental involvement which have been addressed in previous meta-analyses.     

Transient response of piles-bridge under horizontal excitation

Moving ships and other objects drifting on water often impact a bridge's pile foundation. The mechanical model of the piles-bridge structure under horizontal forcing was established, and a time-domain approach based on Finite-difference Method was developed for analyzing the dynamic response of the piles-bridge structure. For a single pile, good agreement between two computed results validated the present approach. The slenderness ratio of the pile, the pile-soil stiffness ratio and the type of the structure influence the dynamic response of the piles-bridge structure. The computed results showed that the stiffness of the structure determines the dynamic response of the piles-bridge structure under horizontal forcing.

Exploring Understandings and Responses to Science: A Program of Longitudinal Studies

This paper will report on the development of a research program by a group of science educators at Kristianstad University, which has its roots in a longitudinal study I conducted concerning students’ developing understandings of ecological processes. Following the insights generated in this first study concerning the nature of student understandings, and the potential of the longitudinal design, a research group has developed at Kristianstad which has extended this work into related areas. This paper will describe my own work and its development, and link it with three projects that use a longitudinal design, which we have subsequently undertaken and in some cases completed. The emphasis within the paper will be on the findings generated by these studies on student learning and response to science, and the particular features of the longitudinal design that allow such insights to emerge. The paper will explore patterns of change, and continuity, as a way of appreciating the particular contributions of longitudinal studies.     

Adding automatic evaluation to interactive virtual labs

Automatic evaluation is a challenging field that has been addressed by the academic community in order to reduce the assessment workload. In this work we present a new element for the authoring tool Easy Java Simulations (EJS). This element, which is named automatic evaluation element (AEE), provides automatic evaluation to virtual and remote laboratories built with EJS by using the server application Goodle grading management system (GMS). The integration of both tools entitles a professor to create interactive virtual and remote laboratories and automatically evaluate the work of their students. As a test bed two case studies are presented; a non-linear controller design virtual laboratory used in an advanced control master course and a servomechanism virtual laboratory used in an undergraduate basic control course.

Learning design and learning analytics in mobile and ubiquitous learning: A systematic review

Mobile and Ubiquitous Learning (m/u-learning) are finding an increasing adoption in education. They are often distinguished by hybrid learning environments that encompass elements of formal and informal learning, in activities that happen in distributed settings (indoors and outdoors), across physical and virtual spaces. Despite their purported benefits, these environments imply additional complexity in the design, monitoring and evaluation of learning activities. The research literature on learning design (LD) and learning analytics (LA) has started to deal with these issues. This paper presents a systematic literature review of LD and LA, in m/u-learning. Apart from providing an overview of the current research in the field, this review elicits elements of common ground between both communities, as shown by the similar learning contexts and complementary research contributions, and based on the research gaps, proposes to: address m/u-learning beyond higher education settings, reinforce the connection between physical and virtual learning spaces, and more systematically align LD and LA processes.     

The existence of dyslexia without severe literacy problems

This paper is concerned with those who display positive indicators on tests for dyslexia but seemingly do not have any severe literacy problems. A case study is presented by way of illustration. On the basis of data from the British Births Cohort Study (12,905 10-year-old children), it was found that some seemingly normal achievers who showed signs of dyslexia (N=422) obtained different results on five measures associated with dyslexia than did other normal achievers without such signs (N=4,998). The measures used were: underachievement at word recognition; and underachievement at spelling, reading comprehension, pseudoword reading, and mathematics. The proportion of boys to girls in the groups was also noted. It is suggested that these were cases of mild dyslexia, who, on the basis simply of reading and spelling tests, might escape detection. The consequences for the concept of dyslexia are discussed, and it is suggested that the needs of dyslexics with only mild literacy problems should not be overlooked.
