Digital resource developments for mathematics education involving homework across formal,non-formal and informal settings

The aim of this paper is to explore further an under-developed area – how drivers of curriculum, pedagogy and assessment conceptions and practices shape the creation and uses of technologically based resources to support mathematics learning across informal, non-formal and formal learning environments. The paper considers: the importance of mathematics learning in informal and non-formal as well as formal settings; how curriculum focuses on pedagogy supporting these needs, contrasting this focus in England and Serbia; and in these contexts, the roles of homework, the potential of technologies and the roles of the teacher. Technological developments to support mathematics learning for 11- to 14-year-old pupils in the two countries are explored and contrasted, and ways that recent developments inform our understandings of formal, informal and non-formal learning through learning activities, learning support and settings are modelled. The conception of ‘extended pedagogies’ is introduced; implications are outlined.

Inclusive education in the Slovak Republic two decades after the dissolution of Czechoslovakia

The fall of Communist regime in 1989 and the dissolution of Czechoslovakia in 1993 significantly affected the educational system of today's Slovakia. As a sovereign state, Slovakia has ratified the Convention on the Rights of Persons with Disabilities obliging its signatories to practise ‘inclusive education’. This article explores the current educational policies of the Slovak Republic in light of this obligation. Using the official statistical data the article argues that the current state educational policies have not succeeded in meeting the objective of practising inclusive education, as the proportion of students educated in segregated special educational provisions has been consistently rising over the last decade. This article attempts to identify particular aspects of the current educational policies which might have contributed to this phenomenon.     

POGIL in the Calculus Classroom

In this paper, we will describe the experience of the authors in using process-oriented guided inquiry learning (POGIL) in calculus at four institutions across the USA. We will briefly examine how POGIL compares to and fits in with other kinds of inquiry-based learning approaches. In particular, we will first discuss the unique structure of a POGIL activity, which includes a model and a learning cycle of specific types of questions. We then turn to a discussion of the particular characteristics of a classroom implementation of a POGIL activity, including facilitation strategies an instructor might use, the importance of specified student roles in groups, and different ways of reporting out. Finally, we provide some preliminary data on student pass rates in non-POGIL and POGIL calculus classrooms in the participating institutions. Throughout the paper, we use examples from student dialogues as groups were working through POGIL activities developed for Calculus I by the authors.     

Exclusion Expected? Cardiac Slowing Upon Peer Exclusion Links Preschool Parent Representations to School-Age Peer Relationships

Attachment theory proposes that children’s representations of interactions with caregivers guide information-processing about others, bridging interpersonal domains. In a longitudinal study (N = 165), preschoolers (M_age = 5.19 years) completed the MacArthur Story Stem Battery to assess parent representations. At school-age (M_age = 8.42 years), children played a virtual ballgame with peers who eventually excluded them to track event-related cardiac slowing, a physiological correlate of rejection, especially when unexpected. At both ages, parents and teachers reported on peer and emotional problems. During exclusion versus inclusion-related events, cardiac slowing was associated with greater positive parent representations and fewer emerging peer problems. Cardiac slowing served as a mediator between positive parent representations and peer problems, supporting a potential psychophysiological mechanism underlying the generalization of attachment-related representations to peer relationships.     

Simulation of Bayes' rule by means of Monte Carlo method

This contribution shows a simple implementation of Monte Carlo simulation method when presenting Bayes' rule. The implementation is carried out in the environment of Microsoft Excel spreadsheets by means of a generator of random numbers. The empiric results gained by simulation serve to confirm the correctness of the chosen procedures in calculations using Bayes' formula.     

Validation of a Tennis Rating Score to evaluate the technical level of children tennis players

The purpose of this study was to create a valid and reliable assessment scale for the evaluation of three basic tennis strokes (forehand, backhand, serve) for 6–12-year-old tennis players, named the Tennis Rating Score for Children (TRSC). Altogether 60 players (21: forehand, 22: backhand, 17: serve) were video recorded (30 frames per second) while performing three main tennis strokes and later evaluated using the TRSC by five tennis trainers at Day 1 and Day 7. Agreement between days and raters was examined using the intraclass correlation coefficients (ICC). A Pearson’s correlation was calculated to determine convergent validity (score related to participant’s level of experience). The reliability between raters was very high for all three main strokes (ICC_FOREHAND = 0.874; ICC_BACKHAND = 0.877; ICC_SERVE = 0.877). The intra-rater test-retests ICCs were also very high (ICC_FOREHAND = 0.885; ICC_BACKHAND = 0.891; ICC_SERVE = 0.887). A large (r_FOREHAND = 0.660) and very large (r_BACKHAND = 0.730; r_SERVE = 0.772) Pearson’s correlations were found between all the ratings and the level of experience. The TRSC is shown to be highly reliable and valid when assessing technical skills in novice players, when compared to actual assessment from coaching experts; this tool may be helpful for tennis coaches to make a more objective diagnostic of the technical level of young tennis players.     

Imaginaries of Invention Management: Comparing Path Dependencies in East and West Germany

The ways in which societies and institutions institutionalize and practice invention management reflects not only how new ideas are valued, but also imaginaries about the role of science and technology for societal development. Often taking the US Bayh-Dole-Act as a model, many European states have recently implemented changes in how inventions at academic institutions are to be handled to optimize their societal impact. We analyze how these changes have been taken up—and made sense of—in regions with different pre-existing infrastructures, practices and semantics of invention management. For doing so, we build on a comparative analysis of continuities and changes in infrastructures, practices and semantics of invention management in North-Rhine Westphalia (NRW, a former Western state) and Saxony (a former GDR state) to reflect on how academic institutions have been handling inventions along transforming socio-political contexts. Building on document analysis and qualitative interviews with research managers, we discuss ongoing differences in practices of invention management and the semantic framing of the societal value of inventions in NRW and Saxony, and discuss how this can be understood before the background of their ideological, political and economic separation until reunification in 1990. Joining the conceptual perspectives of path dependencies and sociotechnical imaginaries, we argue that two critical incidents in the history of these states (the reunification in 1990 and a legal change in 2002) allowed for wide-ranging institutional alignments, but also allowed path dependencies in practices and semantics of invention management to prevail.
