Multimedia and interactivity in distance learning of resuscitation guidelines: a randomised controlled trial

The aim of the study was to conduct a comparative analysis of three forms of knowledge transfer online, taking into account the long-term knowledge growth rate and the satisfaction of students surveyed in respect to distance learning. The cohort of participants for this survey were students of the first degree, studying in the Emergency Medical Services. The authors created three e-learning courses in basic and advanced resuscitation procedures. The level of course participants’ satisfaction was analysed, as well as the knowledge growth rate measured three times: 7, 30 and 90 days, respectively, after finishing the course. The level of satisfaction in all the groups surveyed was comparable. The growth rate for knowledge was the highest in group C in the second and third survey, respectively (30 and 90 days after the end of the course), and a significant difference in favour of course C was demonstrated one month after finishing classes.     

Nurturing learning or encouraging dependency? Teacher constructions of students in lower attainment groups in English secondary schools

‘Ability’ or attainment grouping can introduce an additional label that influences teachers’ expectations of students in specific attainment groups. This paper is based on a survey of 597 teachers across 82 schools and 34 teacher interviews in 10 schools undertaken as part of a large-scale mixed-methods study in England. The paper focuses on English and mathematics teachers’ expectations of secondary school students in lower attainment groups, and explores how low-attaining students are constructed as learners who benefit from specific approaches to learning justified through discourses of nurturing and protection. The authors argue that the adoption of different pedagogical approaches for groups of low-attaining learners to nurture them may in some cases be fostering dependency on teachers and cap opportunities for more independent learning. Furthermore, more inclusive whole-school learning-culture approaches may better allow for students across the attainment range to become independent learners.     

Mutual influence of marital conflict and children's behavior problems: shared and nonshared family risks

This within-family, longitudinal study including biological and stepfamilies investigated mutual influences between marital conflict and children's behavior problems. Children (4 to 17 years; N=296) residing in 127 families drawn from a general population study were investigated at Time 1 and again 2 years later. These nested data were analyzed using multilevel modeling, controlling for previous child behavior or marital conflict. Marital conflict about children predicted change in children's behavior. Children's behavior also predicted an increase in marital conflict, particularly in stepfamilies. Differences between siblings in exposure to conflict and the extent to which siblings were a source of argument increased more in stepfamilies than in biological families. Boys were exposed to more conflict over time than were girls.     

Teachers’ use of educative curriculum materials to engage students in science practices

New reform documents underscore the importance of integrating science practices into the learning of science. This integration requires sophisticated teaching that does not often happen. Educative curriculum materials – materials explicitly designed to support teacher and student learning – have been posited as a way to support teachers to achieve these ambitious goals, yet little is known about how elementary teachers actually use educative curriculum materials to support student engagement in science practices. To address this gap, this study investigated how five upper elementary teachers supported students to engage in science practices during an enactment of two curriculum units. Three of the teachers had units enhanced with educative features, informed by current research and reforms, while two of the teachers had units without these features. The teachers varied in how they supported students in the science practices of justifying predictions, constructing evidence-based claims, recording observations, and planning investigations. For example, some of the teachers with the educative features supported students in constructing evidence-based claims and justifying predictions in ways called for by the educative features. Implications for curriculum developers and teacher educators are discussed based on the patterns found in the teachers’ use of the educative curriculum materials.     

Academic Administrators’ Beliefs About Diversity

As our nation and society becomes more racially and ethnically diverse, college campuses are experiencing a dynamic shift in the student demographic on campus as well. Purposes of the study were to: (a) analyze the beliefs of kinesiology academic unit leaders (i.e., chairs, directors, heads) regarding faculty and student diversity within their programs and departments and (b) inquire about strategic goals for faculty and student diversification within their programs and departments. The participants were 68 administrators (43 men, 25 women) and all current members of the American Kinesiology Association (AKA) as of 2015. Thematic content data analysis of the open-ended probes exposed the recurrent themes: (a) advocacy, motives, and actions; (b) diversity identified, but rarely defined; and (c) history, status, and outlook. Implications of the findings are that issues associated with diversity in kinesiology programs and departments should be addressed with vigor and progressive actions.     

Quality incentive based congestion control for multimedia communication over IP networks

In this paper we introduce a framework for using quality as an incentive to promote proper application level congestion control. Through integrating a joint-source channel coder and feedback-based congestion control scheme, we are able to construct accurate and efficient quality incentives. The framework is applicable in all network architectures where end-to-end congestion control may be used, and is as such not specific to either best-effort or traffic class-based architectures. The concept is presented along with preliminary simulations that highlight the resulting rate control accuracy. We also discuss how to implement some well-known congestion control schemes within our framework.     

Spelling feedback in an ICT-learning environment: Issues of proficiency, training efficiency, and transfer

This study was designed to compare the effectiveness of two different forms of feedback on spelling performance of Dutch Grade-2 students, that is, knowledge-of-results and informational feedback. In the knowledge-of-results feedback condition, the speller is told that the word is spelled incorrectly, whereas in the informational feedback condition, the speller is told what is spelled incorrectly. Three main questions were investigated. One, to what extent does the nature of feedback affect students with good and poor spelling skills differently? Two, does the nature of feedback affect various forms of spelling difficulties differently? Three, is training efficiency differentially affected by the nature of feedback?The results showed that both feedback conditions were equally effective in teaching students the spelling of words, irrespective of spelling level and spelling difficulty. Both feedback conditions led to a similar level of transfer to a set of new words, the effect being stronger in good than in poor spellers. Transfer was best on analogy spellings, followed by rule-based, and worst on idiosyncratic spellings. The poor spellers learned the spelling of words more efficiently in the informational-feedback condition than in the knowledge-of-results condition, whereas for the group of good spellers efficiency was equally large in both conditions.     

Transferring a Teaching Learning Sequence Between Two Different Educational Contexts: the Case of Greece and Finland

In the present paper, we report on the idea of exchanging educational innovations across European countries aiming to shed light on the following question: how feasible and useful is it to transfer an innovation across different national educational settings? The innovation, in this case, Inquiry-Based Teaching Learning Sequences, is recognized as a crucial component of renewal science teaching in European countries. Two local working groups from two different Universities, in Finland and Greece, were created consisting of researchers and experienced primary teachers. The transfer from Greece to Finland was rather challenging because of the differences between the two educational contexts. The initial, as well as the revised Teaching Learning Sequence, were implemented for 11–12-year-old students including the content to be taught, that is Floating-Sinking phenomena and density, and the learning environment aspects such as learning Control of Variables Strategy. A combination of qualitative and quantitative research methods was implemented in order to formulate concrete recommendations on feasible and useful aspect. The feasible aspect adduces answers to the query of “how” this transfer worked in practice. Concerning this aspect, the recognition of what is innovative for each national partner was recognized as a crucial factor for the design and revision of both Teaching Learning Sequences. The useful aspect illuminates students’ improvement in the achievement of conceptual as well as procedural knowledge. The results revealed that the psychological paths that bring about this success are ecumenical and independent of the history of the educational group.
