This paper tries to answer the question whether the promising Content and Language Integrated Learning (CLIL) teaching method also has positive effects on the pragmatic competences of CLIL students compared to their peers in mainstream English as a Foreign Language (EFL) classrooms. To avoid deviances caused by other factors external to the teaching method, only students who have a similar language background were selected for the study by means of a questionnaire. Data on the articulations of requests, thanks, complaints, apologies, invitations, refusals and advice was collected during videotaped English role plays and role enactments. After the role plays/role enactments, students were interviewed about their performance and were given German Discourse Completion Tests (DCTs) to allow a comparison between respective articulations in their L1 and L2. Furthermore, teachers were questioned about the speech acts they used in CLIL and EFL classes and their judgements about the students’ possible activities.
We consider groups defined by non-empty balanced presentations with the property that each relator is of the form, where x and y are distinct generators and is determined by some fixed cyclically reduced word that involves both a and b. To every such presentation we associate a directed graph whose vertices correspond to the generators and whose arcs correspond to the relators. Under the hypothesis that the girth of the underlying undirected graph is at least 4, we show that the resulting groups are non-trivial and cannot be finite of rank 3 or higher. Without the hypothesis on the girth it is well known that both the trivial group and finite groups of rank 3 can arise.
In the last three decades many research studies focused on the topic of multiple representations and their role for learning mathematics. As a result, there is a broad consensus in the scientific community that dealing with multiple representations in the mathematics classroom is a highly relevant matter. However, research addressing the role of the teachers in this context is still scarce. Consequently, this dissertation study raises the question of how much teachers know about and acknowledge this key role of multiple representations for the mathematics classroom. To this end, not only different aspects of teachers' specific professional knowledge and their views were investigated, but also their noticing of changes of representations in instances of student-teacher interaction, which can be seen as a theme-specific noticing. Using a multi-layer model of professional knowledge, this study addresses in particular questions of how such specific aspects of professional knowledge are interrelated and what components of knowledge and views play a role for the teachers' theme-specific noticing.
These research interests were addressed in the scope of three substudies, each of them including two different subsamples (English pre-service teachers/German pre-service teachers, pre-service teachers/in-service teachers, respectively in-service teachers at academic track secondary schools/in-service teachers at secondary schools for lower attaining students), in order to explore the possible roles of cultural background, teaching experience, and school types.
The different aspects of specific professional knowledge and views were assessed by means of a questionnaire instrument. For eliciting the teachers' theme-specific noticing, vignette-based questions were implemented. The data was analyzed mainly by quantitative methods, was however complemented by a qualitative in-depth analysis focusing on how the teachers' theme-specific noticing was informed by different components of their professional knowledge.
The results of this study suggest that the participants did not fully understand the key role of multiple representations for learning mathematics in the sense of their discipline-specific signicance and thus indicate specific needs for teacher education and professional development. Differences between the subsamples of teachers became apparent especially regarding the teachers' more situated professional knowledge and their noticing with respect to dealing with multiple representations. Furthermore, the findings of this study underpin the assumption that within the spectrum between teachers' situated and global professional knowledge and views regarding dealing with multiple representations, different components may be distinguished and suggest that in particular all of these components may play a role for teachers' theme-specific noticing.
This volume is largely about nontraditional data; this paper is about a nontraditional visualization: classification trees. Using trees with data will be new to many students, so rather than beginning with a computer algorithm that produces optimal trees, we suggest that students first construct their own trees, one node at a time, to explore how they work, and how well. This build-it-yourself process is more transparent than using algorithms such as CART; we believe it will help students not only understand the fundamentals of trees, but also better understand tree-building algorithms when they do encounter them. And because classification is an important task in machine learning, a good foundation in trees can prepare students to better understand that emerging and important field. We also describe a free online tool—Arbor—that students can use to do this, and note some implications for instruction.
Fragestellungen zur Konzeptualisierung und Messung professionsbezogener Kompetenzen von Lehrkräften stellen ein hochaktuelles Thema in der mathematikdidaktischen Forschung dar (z.B. Kunter et al., 2013; Kaiser et al., 2015). Trotz unterschiedlicher Ansätze in diesem Bereich besteht weitgehend Konsens darüber, dass Kompetenzen die persönlichen Voraussetzungen zur erfolgreichen Bewältigung berufsspezifischer situationaler Anforderungen beschreiben (Baumert & Kunter, 2013) und prinzipiell erlernbar und vermittelbar sind (Weinert, 2001b). Es gibt jedoch keine „Kompetenz“ per se, da die Beschreibung einer solchen stets einen relevanten berufsspezifischen Kontext voraussetzt (Hartig, 2008). Der Ausgangspunkt zur Beschreibung und Definition einer professionsbezogenen Kompetenz für Lehrkräfte sind folglich die beruflichen Anforderungen, die Lehrkräfte erfüllen müssen, um in Interaktion mit den Schülerinnen und Schülern die Lerngelegenheiten bereitzustellen, die verständnisvolle Lernprozesse ermöglichen (Lindmeier, 2011; Koeppen et al., 2008; Baumert & Kunter, 2013). Für Mathematiklehrkräfte wurde der Umgang mit vielfältigen Darstellungen als eine solche zentrale Anforderung beschrieben (Hill, Schilling & Ball, 2004; Ball, Thames & Phelps, 2008). Zahlreiche Studien weisen darauf hin, dass hierbei die Wechsel zwischen unterschiedlichen Darstellungsformen komplexe kognitive Prozesse erfordern und oftmals für viele Schülerinnen und Schüler zu einer Lernhürde werden (z.B. Ainsworth, Bibby & Wood, 1998; Duval, 2006; Ainsworth, 2006). Lehrkräfte benötigen daher spezifisches Wissen in diesem Bereich, um die Lernenden bei Darstellungswechseln unterstützen zu können (Duval, 2006; Mitchell, Charalambous & Hill, 2014; Dreher & Kuntze, 2015a, b). Lehrkräfte müssen jedoch auch in der Lage sein, Unterrichtssituationen zum Umgang mit Darstellungen zu analysieren, also Beobachtungen in Unterrichtsituationen mit diesem Wissen zu verknüpfen, um potentiell schwierige Darstellungswechsel erkennen zu können (Friesen, Dreher & Kuntze, 2015; Friesen & Kuntze, 2016). Es besteht weitgehend Konsens darüber, dass diese Analyse von Unterrichtssituationen eine wesentliche Voraussetzung dafür darstellt, dass Lehrkräfte überhaupt passende Lernangebote und Hilfestellungen zur Verfügung stellen können (z.B. Sherin, Jacobs & Philipps, 2011; Schoenfeld, 2011; Santagata & Yeh, 2016). Dennoch bleibt in aktuellen Konzeptualisierungen professionsbezogener Kompetenzen von Lehrkräften das Analysieren von Unterrichtssituationen im Hinblick auf potentiell hinderliche Darstellungswechsel weitgehend unberücksichtigt (z.B. Baumert & Kunter, 2013; Kaiser et al., 2015). Im Rahmen dieser Studie wird daher ein solches fachdidaktisches Analysieren von Unterrichtssituationen als wichtige professionsbezogene Kompetenz von Mathematiklehrkräften beschrieben. Da es bislang kaum empirische Studien gibt, in denen eine solche Kompetenz untersucht wurde, soll somit auch ein Beitrag zur Messung fachdidaktischer Analysekompetenz geleistet werden.
Um Kompetenzen von Lehrkräften unterrichtsnah zu erfassen, gelten vignettenbasierte Erhebungen als besonders geeignet (Kaiser et al., 2015; Blömeke, Gustafs-son & Shavelson, 2015). Entsprechend wurde im Rahmen dieser Studie ein vignettenbasiertes Testinstrument mit sechs Unterrichtssituationen aus dem Bereich Bruchrechnung (Klasse 6) entwickelt, in welchen der Umgang mit Darstellungswechseln eine zentrale Rolle spielt. Bislang gibt es wenige Untersuchungen dazu, welche Rolle unterschiedliche Vignettenformate für die Auseinandersetzung mit Unterrichtsvignetten (z.B. für die wahrgenommene Authentizität) und die Analyse zum Umgang mit vielfältigen Darstellungen spielt, dasselbe gilt für unterschiedliche Frageformate. Da die spezifischen Eigenschaften unterschiedlicher Vignet-tenformate und Frageformate bei der Kompetenzmessung jedoch durchaus eine Auswirkung auf die Schwierigkeit der Items haben können (Hartig, 2008), sind Untersuchungen hierzu im Rahmen dieser Studie von besonderem Interesse. Um dem beschriebenen Forschungsinteresse nachzugehen, wurde jede der sechs Un-terrichtssituationen im Testinstrument in drei Formaten (Text, Comic, Video) umgesetzt und offene sowie geschlossene Frageformate zur Analyse des Umgangs mit Darstellungen in den Unterrichtssituationen vorgelegt. Das beschriebene Testinstrument bearbeiteten N = 298 Lehramtsstudierende, Lehramtsanwärterinnen und Lehramtsanwärter sowie praktizierende Lehrkräfte. Die erhaltenen Daten wurden mit Raschmodellen analysiert, um die Qualität der vorgenommenen Kompetenzmessung zu prüfen (Bond & Fox, 2015).
Die Ergebnisse belegen eine gute Auseinandersetzung der Teilnehmerinnen und Teilnehmer mit den Vignetten in allen drei Formaten (Text, Comic, Video), wodurch eine wichtige Voraussetzung für die Analyse der vorgelegten Unterrichtssituation gegeben war. Es zeigte sich, dass fachdidaktische Analysekompetenz zum Umgang mit Darstellungen unabhängig von den eingesetzten Vignetten-formaten (Text, Comic, Video) als eindimensionales Konstrukt modelliert werden kann. Während die drei unterschiedlichen Vignettenformate keinen systemati-schen Einfluss auf die Analyse der Teilnehmerinnen und Teilnehmer zum Umgang mit Darstellungen zeigten, wurde nachgewiesen, dass die Items aus den geschlossenen Formaten systematisch leichter zu beantworten waren. Die Analyseergebnisse der Teilnehmerinnen und Teilnehmer lassen auf eine eher niedrige Ausprägung fachdidaktischer Analysekompetenz zum Umgang mit vielfältigen Darstellungen schließen, da potentiell problematische Darstellungswechsel in den Unterrichts-vignetten häufig nicht erkannt wurden. Insgesamt konnte festgestellt werden, dass die drei Vignettenformate Text, Comic und Video vergleichbar zur Erhebung fachdidaktischer Analysekompetenz zum Umgang mit vielfältigen Darstellungen geeignet sind.
The saving of previously encoded information boosts both memory for subsequent information (saving-enhanced memory; SEM) as well as cognitive performance in general (saving-enhanced performance; SEP). These findings have been replicated in a setting that involves the assistance by an intelligent software that automatically structures and saves work content in an interactive sidebar. It is assumed that beneficial effects on cognitive performance due to (automatic) saving are caused by a reduction in current workload by means of cognitive offloading. We tested this assumption by measuring neural activity in the dorsolateral prefrontal cortex (DLPFC) via functional near infrared spectroscopy (fNIRS)—once after saving and once after deleting of previously collected information that had to be recalled later-on. On a behavioral level, there was a brief benefit of saving. However, cognitive offloading became most apparent on a neural level: after saving, participants showed significantly lower activation in the right DLPFC. Also, the more participants benefited from cognitive offloading, the more they were able to re-access previously collected, saved information. Thus, fNIRS results indicated reduced mental load after saving, confirming the assumption that saving triggers cognitive offloading.
The different facets of professional performance of teachers are being debated in the current educational
research discussion. Both qualitative and quantitative test constructions exist for vignette-based measurement of
competence. For economic reasons, a procedure with closed-ended items is often favored, a reference is required for
determining and comparing alternative responses. This paper sketches out the procedure for identifying adequate
reactions to responses that we call a technical education expert norm (PCK-T). This expert norm is generated from
a multi-step expert survey and, in addition, reveals possible validation steps that can be derived for developing
teaching situations. After a content validation (N1 = 8) a multi-step quantitative survey with specialised subject
experts at schools and universities, departmental heads at public colleges for education and teacher training, as well
as experienced teachers of technology was carried out (N2 = 79; N3 = 76). In order to assess teaching competencies
of pre-service teachers using a vignette-based test procedure, the generated technical education expert norm (PCKT) allows adequate responses to be differentiated from (rather) inadequate responses in the teaching situations
In this study, the relationship between religiosity and value priorities is differentiated, based on a multidimensional model of religiosity (Structure-of-Religiosity-Test). The structure of values is conceptualized using Shalom H. Schwartz’s two orthogonal dimensions of self-transcendence vs. self-enhancement and openness to change vs. conservation. The relationship between these two dimensions and the centrality of religiosity, seven religious orientations, seven emotions toward God, and three political orientations were tested with a correlational analysis in a sample of members of Abrahamic religions, the non-denominational, and organized secularists in Switzerland (n = 1093). The results show, that different values are preferred (self-direction, universalism, benevolence, tradition, security, and power values) depending on the content of the religious orientations and emotions toward God. The results indicate the importance of the content of religious orientations and emotions for predicting value-loaded behaviors.
Research has identified 10 high-leverage teaching practices (HLTPs) that can impact student learning of a foreign language. While acknowledging the importance of this work, more research is needed to inform the preparation of novice teachers to enact these practices. In response, the researchers conducted a case study involving two foreign language teacher preparation programs in the United States and Germany, to better understand how the two very different programs prepare their candidates to implement HLTPs, which HLTPs are emphasized, and how successful they are at preparing their aspiring teachers to implement one practice that has been identified in the research as particularly important (facilitating target language comprehensibility). Survey, teaching observation, and interview data collected from teacher candidates and their instructors suggested the critical nature of select HLTPs, that some of the subcomponents of one of these practices may be more challenging for novice teachers to master than others, and that there may be multiple approaches to preparing foreign language teachers to implement HLTPs.
The article raises the question of whether and how education systems produce social differences internally rather than reproducing pre‐existing “external” inequalities. Linking Niklas Luhmann’s theory of inclusion/exclusion with Charles Tilly’s theory of categorical inequalities, and based on empirical data from various qualitative studies, the article identifies an “observation regime” epistemically constituting the social classification of students and legitimising organisational closure mechanisms in the school system. As an alternative to the “reproduction paradigm,” a research approach guided by differentiation theory is proposed that takes into account that educational inequality operationally arises on the “inside” of the educational system and is caused by unequal inclusion processes.
Females and students of non-dominant ethnicity are less likely to aspire to science careers. However, overcoming discrimination in science and chemistry is a challenging task, especially in vocational orientation. Thus, there is a need for strategies to support young women in their identity formation in science and chemistry. This article presents a scheme for supporting young women’s science identity formation in conversations about vocational orientation. The goal is to support young women in developing a positive attitude towards careers in chemistry. This attitude is part of cultural chemistry capital. The scheme was developed based on a study conducted as part of the project DiSenSu. Here, coachings for vocational orientation for young women in science and chemistry are provided, following the idea of Science in Public. In the coaching, the attitudes towards science and chemistry were determined using quantitative data. Based on these results, coaches conducted conversations with the participants. Qualitative analysis of 11 conversations revealed strategies coaches used to support young women in their vocational orientation. The study shows how the participants’ attitude towards careers in chemistry is used as a starting point for coachings. Also, it provides strategies that can be used to promote young women’s cultural chemistry capital.
Technology criticism and data literacy: The case for an augmented understanding of media literacy
(2020)
Reviewing the history of media literacy education might help us to identify how creating media as an approach can contribute to fostering knowledge, understanding technical issues, and to establishing a critical attitude towards technology and data. In a society where digital devices and services are omnipresent and decisions are increasingly based on data, critical analysis must penetrate beyond the “outer shell” of machines – their interfaces – through the technology itself, and the data, and algorithms, which make these devices and services function. Because technology and data constitute the basis of all communication and collaboration, media literate individuals must in the future also have a sound understanding of technology and data literacy. This article examines the relevance of this broader definition of literacy and delivers a forward-looking defense of media literacy education in schools. It also posits the thesis that the digital transformation represents a challenge, which is confronting society, politics, and education alike.
When “software takes command”, people take fright – a reaction which frequently accompanies change or novelty. Their fears are understandable, but they also cloud people’s view of the potentials that digital tools and digital media hold for society and especially educational contexts. Their fears also define societal debates and contribute to a general lack of ambition when it comes to seizing the opportunities for broad collaboration in the design of a “digital society”. This paper identifies a selection of conceptual digital potentials, presents the initial findings of an ongoing study and uses these as a basis to formulate recommendations for reclaiming society’s formative authority over the shape of the digital in its midst.
Although raised in the early days of research on teacher noticing, the question of context specificity has remained largely unanswered to this day. In this study, we build on our prior research on a specific aspect of noticing, namely teachers’ analysis of how representations are dealt with in mathematics classroom situations. For the purpose of such analysis, we examined the role of context on the levels of mathematical content area and classroom situation. Using a vignette-based test instrument with 12 classroom situations from the content areas of fractions and functions, we investigated how teachers’ analyses regarding the use of representations are related concerning these two mathematical content areas. Beyond content areas, we were interested in the question of whether an overarching unidimensional competence construct can be inferred from the participants’ analyses of the different individual classroom situations. The 12 vignettes were analysed by N = 175 secondary mathematics teachers with different degrees of teaching experience and their written answers provided the data for this study. Our findings show that the data fit the Rasch model and that all classroom situations contributed in a meaningful way to the competence under investigation. There was no significant effect of the mathematical content area on the participants’ analyses regarding the use of multiple representations. The results of the study indicate that explicitly considering questions of context can strengthen research into teacher noticing.
The article analyses the strategies of Hungarian higher education interest organisations against the encroachments on academic freedom by Viktor Orbán's governments. We contrast the 2012–2013 and 2017–2019 protest waves and find that innovations in strategy came from new organisations in both periods, whereas established ones were rather passive or opted for the status quo. However, in the second period, new actors consciously declined to pursue wider systemic goals and aimed at building up formal organisations instead of loose, movement-like networks. The focus on keeping a unified front and interest representation on the workplace level did not change the overall outcome. Just like during the first period, the government was able to reach its goals without major concessions. Nevertheless, during the second protest wave the government was unable to divide and pacify its opponents, which stripped it of its legalistic strategy and revealed its authoritarianism.
This article presents an analysis of the formation of organized interest groups in the post-communist context and organizational populations over time. We test two theories that shed doubt on whether vital rates of interest groups are explained by individual incentives, namely, the political opportunity structure and population ecology theory. Based on an analysis of the energy policy and higher education policy organizations active at the national level in Hungary, Poland, and Slovenia, we find that while the period of democratic and economic transition indeed opened up the opportunity structure for organizational formations, it by no means presented a clean slate. Communist-era successor and splinter organizations survived the collapse of communism, and all three countries entered transition with relatively high density rates in both organizational populations. We also find partial support for the density dependence hypothesis. Surprisingly, the EU integration process, the intensity of legislative activity, and media attention do not seem to have meaningfully influenced founding rates in the two populations

The article tests the energy–stability–area (ESA) model of interest group population density on a sample of different 2018 Czech, Hungarian, Polish and Slovenian energy, higher education and health care interest organisation populations. The unique context of recent simultaneous political, economic and in the cases of Czechia and Slovenia, national transitions present a hard test for population ecology theory. Besides the area (constituency size) and energy (resources, issue certainty) terms, the article brings the stability term back into the center of analysis. The stability term, that is, the effect of a profound change or shock to the polity is operationalised as Communist-era population densities. As all three policy domains are heavily state controlled and tightly regulated, the effect of neocorporatist interest intermediation is also tested. The article finds strong support for the energy and neocorporatism hypotheses and provides evidence for the effect of communist-era organisational population density on post-transition densities: The size of 2018 organisational populations is found to be dependent on pre-transition densities. The relationship is, however, not linear but curvilinear. Nevertheless, the analysis indicates that the effect of pre-transition population size is moderated by other environmental level factors.
Deutsch:
Der Artikel testet das Energie-Stabilitäts-Gebietsmodell (ESA) der Bevölkerungsdichte von Interessengruppen an einer Stichprobe verschiedener tschechischer, ungarischer, polnischer und slowenischer Bevölkerungen von Energie-, Hochschul- und Gesundheitsorganisationen aus dem Jahr 2018. Der einzigartige Kontext der jüngsten gleichzeitigen politischen, wirtschaftlichen und im Falle Tschechiens und Sloweniens nationaler Übergänge stellt die Theorie der Populationsökologie auf eine harte Probe. Neben den Begriffen Flächen (Wahlkreisgröße) und Energie (Ressourcen, Themensicherheit) rückt der Artikel den Stabilitätsbegriff wieder in den Mittelpunkt der Analyse. Der Stabilitätsbegriff, dh die Auswirkung einer tiefgreifenden Veränderung oder eines Schocks auf das Gemeinwesen, wird als Bevölkerungsdichte der kommunistischen Ära operationalisiert. Da alle drei Politikbereiche stark staatlich kontrolliert und streng reguliert sind, wird auch die Wirkung neokorporatistischer Interessenvermittlung getestet. Der Artikel findet starke Unterstützung für die Energie- und Neokorporatismus-Hypothesen und liefert Belege für den Effekt der organisationalen Bevölkerungsdichte der kommunistischen Ära auf die Dichte nach dem Übergang: Die Größe der Organisationsbevölkerung im Jahr 2018 hängt von der Dichte vor dem Übergang ab. Der Zusammenhang ist jedoch nicht linear, sondern krummlinig. Dennoch zeigt die Analyse, dass der Effekt der Bevölkerungsgröße vor dem Übergang durch andere Umweltfaktoren gemildert wird.
The data on the formations and dissolutions of Czech, Hungarian, Polish and Slovenian national-level healthcare, higher education and energy policy interest groups show that there were relatively large organizational populations in these countries already at the outset of post-communist transition in 1990. In other words, there was no tabula rasa – the evolution of interest organizations did not start completely anew. There was, however, a substantial variation between policy fields and countries in the sizes of these pre-transition populations. What explains this variance? The chapter explores in detail the formation rates across the four countries and three policy fields through time. In their explanation, the authors focus on the nature of the communist regime, its overall repressiveness, the periods of political and economic liberalizations and the political mobilization and fragmentation in the period leading up to regime change. On the basis of the Hungarian sub-sample, where such data are reliably available, the chapter also compares the mortality rates of organizations founded before and after transition. The findings shed new light on the debates on civil society development and democratization in post-communist societies. The chapter also draws attention to the importance of the proper operationalization of fundamental political changes to the polity in population ecology theory in general, and in the energy–stability–area model of organizational density in particular.
