The complex associations between scientific reasoning and advanced theory of mind

This 6-wave longitudinal study (2014–2018) of 161 German 5- to 10-year-olds from a midsized city and rural area in southern Germany (89 females, 72 males; predominantly White; mostly middle class) found that scientific-reasoning abilities first develop at 6 years. Abilities were highly stable, with the kindergarten score predicting 25% of end-of-elementary-school variance. Individual but not developmental differences were related to language abilities (0.39), mindreading skills (0.33), and parental education (0.36). In early elementary school, mindreading skills predicted scientific reasoning (0.15), but not vice versa; in late elementary school, bidirectional associations emerged (0.11–0.33). Our findings suggest that mindreading is a precursor for the development of scientific reasoning and that older children use scientific reasoning to revise their advanced theories of mind.     

A strengthened teaching mission in preschool: teachers' experiences,beliefs and strategies

This paper aimed to explore how preschool teachers' experience their strengthened teaching mission, specifically when working with scientific exploration. The study was based on the philosophy of the life-world, a branch of the phenomenological movement. Life-world philosophy focuses on the concrete reality humans inhabit and is responsive to its inherent ambiguity. The data consisted of written teacher responses and follow-up interviews. The findings showed a broad and multidimensional way of working with science and exploration in which embodied experiences and intertwined relationships were prominent. Teachers' notions of what constitutes scientific exploration and learning represent a combination of science as literacy and science as inquiry, emphasising democracy, aesthetics, experimentation and reflection. Being present and focusing children's relationship with the phenomena seem to be teachers' strategies of handling their strengthened teaching mission.     

Improving reading in children with German as a first or second language

The study Improving Language And Reading Skills (LARS) in children with German as a first or second language evaluates a newly developed differentiating programme for reading in terms of its effects on the reading and language ability of second graders with German as a first or second language. The participant group consisted of 105 children. Fifty-five children belonged to the group that received the programme (LARS-group) and 50 children received traditional instruction (TI-group). The reading, spelling and language ability of each participating child were assessed before and after the programme period. The children of the LARS-group were supported over three months in terms of reading texts and completing the corresponding tasks. The texts and the tasks were adapted to the students' ability levels (three different ability levels: above average, average and below average level in reading). The results indicate that the learning outcomes for children in the LARS-classes were significantly higher for reading fluency and comprehension, but no effect was observed for language and spelling. The results suggest that the LARS programme was equally effective for children with German as a first or second language.     

Factors mathematicians profess to consider when presenting pedagogical proofs

This paper concerns proof presentation at the university level. We report on a study in which we observed ten mathematicians constructing or revising proofs for pedagogical purposes. We highlight the factors that they claimed to consider when completing these tasks. We found that intended audience and medium (lecture or textbook) influenced proof presentation. We also found that, although mathematicians generally valued pedagogical proofs featuring diagrams and emphasizing main ideas, these mathematicians did not always incorporate these aspects in the proofs they constructed or revised.     

Why and how mathematicians read proofs: further evidence from a survey study

In a recent paper (Weber & Mejia-Ramos, Educational Studies in Mathematics, 76, 329–344, 2011), we reported findings from two small-scale interview studies on the reasons why and the ways in which mathematicians read proofs. Based on these findings, we designed an Internet-based survey that we distributed to practicing mathematicians working in top mathematics departments in the USA. Surveyed mathematicians (N?=?118) agreed to a great extent with the interviewed mathematicians in the exploratory studies. First, the mathematicians reported that they commonly read published proofs to gain different types of insight, not to check the correctness of the proofs. Second, they stated that when reading these proofs, they commonly: (a) appeal to the reputation of the author and the journal, (b) study how certain steps in the proof apply to specific examples, and (c) focus on the overarching ideas and methods in the proofs. In this paper, we also report findings from another section of the survey that focused on how participants reviewed proofs submitted for publication. The comparison of participant responses to questions in these two sections of the survey suggests that reading a published proof of a colleague and refereeing a proof for publication are substantially different activities for mathematicians.     

Advancement towards the scholarship of teaching and learning through the writing of teaching portfolios

This study explores the impact academic teachers’ writing of a teaching portfolio can have on their professional learning. Through an open-ended questionnaire, 26 academics from three faculties reported on insights, effects on teaching practice, and effects on collegial exchange that the portfolio writing entailed. We discuss how the experienced impact relates to the three competence levels excellence, expertise and scholarship of teaching and learning. With regard to academic development, we conclude that the writing of reflective teaching portfolios has the potential of contributing to an emerging academic community of practice characterised by a scholarly approach to teaching and learning.     

Systematic educational change and teacher skill-building in developed and developing countries: the importance of teacher peer learning groups

Many developed and developing countries are seeking to systematically transform their education processes through Information and Communication Technology (ICT). The aim of this paper is to present findings from one aspect of a larger ICT study in a particular location in a developing country, with the specific focus presented here being ICT professional development and impacts. Research methods in the study included teacher and school leader surveys, targeted interviews and also case studies. Findings at a systems level generally indicated insufficient coordination of training and minimal follow-up occurring. In case study situations in which the school leader ensured a schoolwide approach to the professional learning of teachers, ICT was more embedded into student learning processes in classrooms. Considering ICT and other professional learning relevant to education, this paper has relevance for policy developers and school leaders in developed and developing world contexts. The need exists for using coordinated professional development processes, with more centralised ‘one-off’ training supplemented by schools and districts. The establishment of peer learning groups or mentors to support skill-building over time is also needed. Through these ongoing processes, teachers can more effectively make changes in their teaching practices, with potential impacts on student learning.     

Physical performance in female handball players according to playing position

Demands for female handball players are not yet sufficiently specified, especially not with respect to position-specific performance. For optimal match preparation, individual training based on specific demands of each position is necessary. Consequently, the aim of the study was to gain insight into position-specific differences in female handball players in order to establish position-specific training recommendations. Data from 652 female players from German leagues of all levels were analyzed using a test-battery assessing handball-relevant physical performance factors. Players were tested during their usual training in their regular training locations for running, throwing speed, jumping height, reaction-speed, basic running endurance, arm and abdominal muscle strength and hamstrings and lower back flexibility. Significant differences between positions were found for several parameters, while the differences were pronounced variably at the different performance levels. For example, goalkeepers performed worst in the Half-Cooper test (p?<?0.001) at elite level with wings displaying the best values. Halfbacks had the highest throwing speed (p?<?0.001) and jumping heights (p?<?0.002) at elite level. Goalkeepers were slowest for best and mean value out of five attempts (p?<?0.001; p?<?0.010) in 20?m sprint but, together with wings outperformed half and centre backs at elite level in 30?m sprint (best out of two attempts, p?<?0.001). Goalkeepers also did fewer chin ups than wing and back players at elite level (p?<?0.003). The present study demonstrated positional differences regarding physical performance parameters, thus suggesting the need to intensify position-specific training, especially for goalkeepers during preparation and in-season. Also, position-specific testing during selection-processes might be indicated.     

Professional minutia and their consequences: provenance, context, original identification, and anthropology at the Field Museum of Natural History, Chicago, Illinois

Historical settings structure how archivists and museum staff understand their work and how they apply relevant professional principles including the three core principles of provenance, context, and original identification. Their professional practices shape how the public understands or reads “original” artifacts and records. In helping to define what originals (artifacts and documents) are at a particular point in time, archivists and museum staff reinforce, support, or contradict theoretical paradigms, discourses, and social narratives on ethnicity, empire/internal colonialism, class, and gender among others. The article discusses two exemplary cases from the museum world that illustrate how the application of the three core principles is influenced by historical conditions and theoretical concepts and how these contingent applications influence what originals come to signify. In the first example, the theoretical concept of social evolution and the World Columbian Exposition in Chicago informed the founding, collecting, describing, and displaying of American Indian objects at the Field Museum of Natural History in 1894. Reflecting this, provenance, context, and original identifications were defined to mean different things for Euro-American versus American Indian objects and records, and Native Americans and others challenged these definitions and practices at the time. In the second example, the 1929–1933 making and displaying of the Hall of Races, a specific race anthropological understanding of race created unambiguous race anthropological provenance, context and original titles (identifications) for both the exhibit and individual race sculptures. By altering information concerning the three principles over the next 60 years, the Field Museum consciously destroyed the integrity of the originals and their meanings. The exhibit had become a political liability and the museum wanted to erase any trace of the race anthropological roots of the project and its sculptures. The article ends by asserting the contingency and importance of the three core principles for archivists and museum staff regardless of the format of the material involved and adds a few related observations for our contemporary hybrid, that means physical and digital, work world.
