Development of a Learning Progression for the Formation of the Solar System

This study describes the process of defining a hypothetical learning progression (LP) for astronomy around the big idea of Solar System formation. At the most sophisticated level, students can explain how the formation process led to the current Solar System by considering how the planets formed from the collapse of a rotating cloud of gas and dust. Development of this LP was conducted in 2 phases. First, we interviewed middle school, high school, and college students (N?=?44), asking them to describe properties of the current Solar System and to explain how the Solar System was formed. Second, we interviewed 6th-grade students (N?=?24) before and after a 15-week astronomy curriculum designed around the big idea. Our analysis provides evidence for potential levels of sophistication within the hypothetical LP, while also revealing common alternative conceptions or areas of limited understanding that could form barriers to progress if not addressed by instruction. For example, many students' understanding of Solar System phenomena was limited by either alternative ideas about gravity or limited application of momentum in their explanations. Few students approached a scientific-level explanation, but their responses revealed possible stepping stones that could be built upon with appropriate instruction.     

Students' Argumentative Writing Skills in Science and First-Language Education: Commonalities and differences

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science.     

Organisational knowledge creation strategies: A conceptual framework

The main purposes of this article are to identify the dimensions of organisational knowledge creation strategies (EICE model: exploration, institutional entrepreneurship, combination, exploitation) and to clarify the relationship between the organisational knowledge creation strategies and its knowledge asset. For these purposes, guided by knowledge-based view and knowledge creation theory, we propose an EICE model and explore its effect on the knowledge asset. We further suggest the managerial implications and theoretical implications. The main managerial implication is that the knowledge creation strategies model may help manager to make effective strategies for knowledge creation within the organisation. The main contributions to organisation theory are extending Nonaka's knowledge creation theory to form a new strategic model for knowledge creation.

From in-service teacher development to school improvement: factors of learning transfer in teacher education

In-service teacher development programs are perceived as a common way to foster school improvement. Nevertheless, program evaluation to date ends with the assessment of acquired knowledge, skills, and motivation, frequently disregarding the actual learning transfer and its conditions. This study aimed to investigate how individual and situational factors interact and contribute to learning transfer in an in-service teacher development program. We tested a transfer model derived from human resources development research. One hundred and twenty-nine teachers aged 25–62 years (87% female), participating in an in-service development program, were surveyed three times during the program. Results of path analyses suggest that not only especially individual factors are critical for learning transfer in the context of school improvement, but also that program and environmental factors have important effects. They moderated the effects of the individual factors.     

Sex and the Quiet Schoolgirl

The article is based on a year's ethnographic work at a West Midlands comprehensive school, which is described. The usual genderising pattern of subject choice and behaviour are identified, and used as the basis of an analysis of the differences, real and imagined, between boys and girls and their expectations of secondary schooling.

Having identified quietness as one of the distinguishing characteristics of girls at Cator Park school, I relate this to their own assessment of how they accommodate to the demands of school. This highly selective adaptation is suggested as one reason why the boys are puzzled by the behaviour of girls in school, and it is suggested that it allows the girls to retain their private identity outside school. The conclusion is that quietness is a successful adaptation to the situation of girls in school, and should not be viewed as a weakness.     

Navigating OER: The Library’s Role in Bringing OER to Campus

In 2014, three librarians at the University of San Diego came together to explore open educational resources (OER). Coming from both technical services and digital collections, we were well-versed in the economic challenges facing today’s libraries. In order to formulate the approach that would work best for our campus, we first had to educate ourselves on the past, present, and possible future of the Open Access movement. While traditionally Open Access has focused on serials, OER offer the opportunity to expand its benefits to other formats. This article examines opportunities and tensions surrounding OER, as well as highlighting major players on the OER landscape. Our efforts began with a focus group for faculty to assess their own knowledge of and opinions on OER. After establishing a stipend budget, we sent out a call for proposals to faculty who were interested in participating in the Copley OER Initiative.     

Segment coupling and coordination variability analyses of the roundhouse kick in taekwondo relative to the initial stance position

The initial stance position (ISP) has been observed as a factor affecting the execution technique during taekwondo kicks. In the present study, authors aimed to analyse a roundhouse kick to the chest by measuring movement coordination and the variability of coordination and comparing this across the different ISP (0°, 45° and 90°). Eight experienced taekwondo athletes performed consecutive kicking trials in random order from every of the three relative positions. The execution was divided into three phases (stance, first swing and second swing phase). A motion capture system was used to measure athletes’ angular displacement of pelvis and thigh. A modified vector coding technique was used to quantify the coordination of the segments which contributed to the overall movement. The variability of this coordination (CV) for each ISP was also calculated. Comparative analysis showed that during the stance phase in the transverse plane, athletes coordinated movement of the trunk and thigh with a higher frequency of in-phase and lower frequency of exclusive thigh rotation in the 0° stance than the 90° stance position (P < 0.05). CV was also influenced by the different ISP. During the first swing and the majority of the second swing phase, predominant in-phase coordination of the pelvis and thigh was observed. Including exercises that require in-phase movement could not only help athletes to acquire coordination stability but also efficiency. The existence of a constraint such as ISP implies an increase of the variability when the athletes have to kick from ISP they are not used to adopt (i.e., 0° and 90° ISP) as an evidence of adaptability in the athletes’ execution technique.     

Reading-Related Skills in Earlier- and Later-Schooled Children

We investigate the effects of age-related factors and formal instruction on the development of reading-related skills in children aged 4 and 7 years. Age effects were determined by comparing two groups of children at the onset of formal schooling; one aged 7 (later-schooled) and one aged 4 (earlier-schooled). Schooling effects were measured by comparing the later-schooled group with earlier-schooled age-matched controls. There were significant effects of age and schooling on phonological awareness and visual–verbal learning, and an effect of age, but not schooling, on vocabulary and short-term verbal memory. We conclude that age-related factors and reading instruction contribute to the development of phoneme awareness and that vocabulary and verbal memory improve with age.     

The language of friendship and identity: children’s communication choices in an interfaith exchange

The development of partnerships between schools and school children of different religious and cultural backgrounds is currently being promoted at national level in an attempt to encourage social cohesion in ethnically and religiously diverse societies. This article reports on one such partnership, a programme of email communication between children from primary schools in Leicester and East Sussex. It uses concepts of presence and space to analyse the different linguistic and paralinguistic devices children employ to construct their identities as friends and as representatives of their communities, and to project these identities across a cultural divide. Evaluation of the children’s language choices identifies tensions and limitations as well as possibilities. The article makes use of Derrida’s deconstruction of hospitality as it questions a too ready adoption of the discourse of friendship for children’s intercultural encounter, and suggests that the development of a more sophisticated language of interest, politeness and respect provides them with a firmer foundation for positive and productive dialogue with religious difference.
