The article "Issue 32(1)" in the Communications of the German Mathematical Society (DMV) covers various topics such as the DMV Student Conference 2024 in Ilmenau, the significance of mathematics in museums, job opportunities for mathematics graduates, and the name of the DMV. The president of the DMV emphasizes the need to attract more and younger members and to make greater efforts towards women and diversity. It also reports on the discussion about renaming the DMV, for which suggestions from members are being collected. The 2023 PISA study shows that the average mathematical and reading competencies of adolescents in many OECD countries have declined compared to the previous study in 2018. Scientific competence has also decreased. In Germany, the performance losses in all three areas are above average. The reasons for the deterioration are mainly attributed to the effects of the COVID-19 pandemic, as well as language difficulties, interest, and motivation. The exhibition "From Newton to Einstein - a journey through space and time" was developed at the Max Planck Institute for Gravitational Physics in Potsdam and is now on display in Tübingen. The award winner Carla Cederbaum has also developed other projects, such as a book on mathematical magic tricks and the publication series "Oberwolfach-Snapshots of Modern Mathematics". Mathematicians Carolin Mehlmann and Thomas Richter from the University of Magdeburg participated in an expedition of the Polarstern to the Arctic Ocean to calibrate a new hybrid sea ice model. The hybrid sea ice model combines particle and continuum methods to better resolve the different sea ice regimes on different local scales. The text deals with the deformation theorem in differential geometry. It is shown that a manifold with boundary possesses a metric with certain properties if the double of the manifold carries such a metric. The question of whether the converse of this statement holds is also raised. The text deals with hypothesis testing and the problem of multiple error probability. Various methods for solving this problem are presented, including the Bonferroni correction and the development of better methods taking into account the dependency structure of the tests. It also addresses pseudoline arrangements, which have connections to combinatorics, geometry, and computer science. The text deals with various mathematical topics, including sorting networks, pseudoline arrangements, Rubik's cube, the PISA study, calculating machines, student studies, Felix Klein, and international cooperation in mathematics. Various concepts and applications are explained, such as the creation of sorting networks from pseudoline arrangements, the use of Markov chains to generate random pseudoline arrangements, and the development of calculation aids and calculating machines. The importance of student studies and international cooperation in mathematics is also emphasized. The text provides an insight into various mathematical topics and their applications.

The wealth of source material produced by Roman notaries has long been neglected. Only in recent decades has it been systematically evaluated by researchers. Given the fragmentary source situation in general, these atti notarili add considerable detail to our knowledge of everyday life. They provide insights not only into the Rome of the popes, which has received considerable attention, but above all into the Rome of the Roman people, much less studied. This paper focuses not on another notary, but on the question of the potential contribution of this genre of sources to the history of late medieval Rome. We see how clients belonging to different social groups approach different notaries. We understand the typical concerns and problems of Roman society, ranging from the debtor imprisoned in a dungeon to the Colonna family in their palazzo. We find confident Florentines with their business dealings, German bakers and their partnership contracts, impoverished monasteries with their growing debts. We see the building boom of the Renaissance and how Piazza Navona is transformed from a campus into a platea, as well as rural Rome within the walls and its countless vineyards.

The Peace of Venice (1177), which ended the nearly twenty-year-long schism between Pope Alexander III and his opponents supported by Emperor Frederick I Barbarossa, has long been the subject of controversy among scholars, who focused initially on the concrete provisions of the treaty and more recently on the symbolic acts that affirmed it. This paper uses Alexandrian sources to concentrate on peace itself as the pope's most important political goal: the biography of Alexander written by his cardinal Boso, the frescoes in the Lateran Palace painted after the victory, and other statements made by the pope himself and his supporters reveal his primary goal to be the restoration of unity and peace. This thinking may have been rooted in the Christian ethic of peace as well as in the enduring ideal of cooperation between pope and emperor. It offers an explanation for the pope's willingness to compromise in Venice, often viewed with astonishment today, expressed through the choice of location, the staging, as well as personnel and material decisions. Alexander did not aim to supercede the emperor, nor to achieve victory on specific issues in detail; instead, his goal throughout the schism seems to have been a return to peace and cooperation.

The paper is an overview of the musicological research project „Towards a global history of music", which was carried out between 2013 and 2017 on the basis of a Balzan Prize for Musicology (2012), with the assistance of international music research institutes and their specialists. A main outcome of the project are three collective volumes of papers, published in 2018, 2019 and 2021, respectively. The project has viewed the variety of musical experiences around the world as a historical unfolding, to be explored via a „long path" through both geography and history. It has queried the enlightenment idea of a fundamental unity of all music (universalism), and the often fragile status of musical-cultural identities on the regional or national levels. It has sought to join methodologies of ethnomusicology and historical research, and has observed that the concepts of music and historiography themselves are less than universal. To the discourses of globalisation and modernisation, the project has added the alternative of transculturality, allowing for more neutral or participatory interpretations of cultural encounter. Summarising this research, tensions between nation and migration, regionalism and adaptation, ‚radial' and ‚imposed' globality are shown. The paper proposes to expand such studies into non-scientific practice and to find new institutional bases, which would benefit further global understanding and sharing. [ABSTRACT FROM AUTHOR]

This paper develops out of a specific event. In 2020, the town of Münsingen in the Swabian Alps commissioned its authors to write a historical report on the Italian Fascist Monterosa Division, focusing on its function and role in the German occupation of Italy from 1944 to 1945. The issue to be clarified was the extent to which the division was involved in war crimes during this period. The background to the request was a monument erected in 1986 in the Ehrenhain, Münsingen's „grove of honour", by the division's veterans' association (Associazione degli appartenenti alla divisione Monterosa). This monument has since led to repeated controversy and heated debate over its Fascist symbolism and the division's involvement in anti-partisan warfare in Italy. Our paper focuses on the experience of officers in the Fascist regime, the division's operations against partisans and at the front, its crimes, and the attempts of the veterans' association in the post-war period to gain official recognition in both Germany and Italy. The Monterosa Mountain Division was created in 1943/1944 by Benito Mussolini's Repubblica sociale italiana (RSI) as one of four military divisions to join front-line combat with the German Army in Italy. Largely composed of young conscripts from Northern Italy, its older non-commissioned officers had extensive war experience from the Italian occupation of Greece and the Balkans, and from the Eastern Front. Its commander, General Mario Carloni, was a hardliner, an energetic, ruthless, and politicised Fascist officer who after the collapse of the Italian state in 1943 chose to continue fighting for Mussolini's side and to support the German occupation of Italy. German instructors trained the Monterosa Division in Münsingen. In late August 1944, it was sent to Italy and assigned to coastal defense duties on the east coast of Liguria, an area almost completely controlled by partisans. The division thus became involved in anti-partisan actions and began to take hostages, shoot civilians and prisoners of war, and destroy village houses. In 1951, a division association was founded, with former General Carloni as its honorary president. Until 2001, it tried in vain to gain recognition from the Associazione Nazionale Alpini (ANA), the most important veterans' and reservists' association of Italian mountain troops. In Germany, on the other hand, the former Monterosa soldiers found faster access to veterans' associations. The first visit by former division members to Münsingen took place as early as 1952. In the 1970s, these visits became increasingly regular and were given official sanction. During the 1980s, the division association's connections further expanded and ultimately resulted in the erection of a memorial to the fallen. In Germany, of all places, the RSI veterans received the recognition that was so difficult for them to obtain in their home country. [ABSTRACT FROM AUTHOR]

This paper explores how students build narrative in collaborative reading processes using the picture book Wazn Teez? (Ellis 2017) to construct the narrative in collaborative reading processes. The focus is on their linguistic and school experiences as well as the differences in interaction in the construction of meaning. Students with Arabic, German and Russian as their first languages were examined in an exploratory study. [ABSTRACT FROM AUTHOR]

The Ellsberg Paradox, discovered by Daniel Ellsberg, is an important paradox in economic theory that raises the question of how people estimate probabilities. It refers to the decision between red and black balls in an urn and shows that people who answer "red" to the first question and "black or yellow" to the second question contradict themselves. Daniel Ellsberg became known for the publication of the Pentagon Papers and was charged with espionage and treason, but the trial was declared flawed due to misconduct by the prosecution and the government. Ellsberg also showed that people violate the axiom of independence of irrelevant alternatives and that subjective probabilities cannot be added. The author of the article, George Szpiro, is a Swiss-Israeli journalist and author. [Extracted from the article]

Das Studium in Schweden und somit auch das Deutsch- bzw. Germanistik-Studium sieht eine Wissenschaftsorientierung von Beginn an in allen Bereichen der Lehre vor, d. h. auch in Lehrveranstaltung zu Sprachfertigkeit und zur Landeskunde der deutschsprachigen Länder. Der vorliegende Beitrag beschreibt zunächst diese spezifischen Hintergründe, um sich sodann mit der Frage auseinanderzusetzen, wie die Lehre der Landeskunde an schwedischen Universitäten stärker wissenschaftsorientiert gestaltet werden kann. Einblicke in Curricula und Unterrichtspraxis sowie Daten aus einem kürzlich abgeschlossenen Dissertationsprojekt verdeutlichen zudem das Potenzial kulturwissenschaftlich orientierter Landeskunde-Ansätze für eine explizite Wissenschaftsorientierung. In Sweden, university studies and hence also German Studies require research-based teaching on all levels. This even includes regular language courses and courses on Landeskunde, i.e. on culture, history and society. This paper describes the specific context of German Studies in Sweden and demonstrates how seminars on Landeskunde can be developed in an even more research-oriented way. By analysing existing curricula and specific teaching practices as well as by utilising results of a recently completed PhD project this paper delivers new insights into teaching German at Swedish universities and illustrate the learning potential of a cultural-studies-based concept of Landeskunde for research-oriented teaching.

Der vorliegende Beitrag fokussiert den Wandel und die Neuerungen innerhalb der Germanistik der Universitat Autònoma de Barcelona (UAB) anhand eines Abrisses über die lokalspezifischen Entwicklungslinien des Studiengangs seit den 1980er Jahren. In den späten 2000er und den aktuellen 2010er Jahren waren und sind die lokalen Entwicklungen stark von den Auswirkungen der 2008 ausgebrochenen Wirtschaftskrise geprägt, die Spanien mit besonderer Härte getroffen und durch die damit verbundenen Stellenstreichungen auch das aktuelle Unterrichtskonzept der Germanistik und des DaF-Unterrichts der UAB beeinflusst hat. Nach Erläuterungen zu diesem Unterrichtskonzept werden abschließend die Herausforderungen und Perspektiven im Bereich der künftigen instituts- und lokalspezifischen Curriculumplanung erläutert. This paper focusses the changes and innovations within the German program at the Universitat Autònoma de Barcelona (UAB) by describing the program's local development trajectories from the 1980 s onward. Since the late 2000 s and the current 2010 s these development trajectories have been characterized by the effects of the economic crisis in 2008, which hit Spain drastically and has, due to staff cuts, also influenced the current German program's teaching concept. After a description of this concept this paper focusses on the challenges and prospects regarding the local curriculum design. [ABSTRACT FROM AUTHOR]

By suitable markings, the stones can generate exclusively non-periodic tilings. The tiling can be generated by projecting points of the five-dimensional lattice Z5 onto the plane. The Penrose tilings are connected to the discovery of quasicrystals and have led to a wave of research in the field. [Extracted from the article]

The article "Logbook Mathematics" deals with mathematical jokes and April Fools' jokes. It is mentioned that Martin Gardner made some April Fools' jokes in April 1975, such as the claim that the theory of relativity had been disproven. The number eπ√163 is now referred to as the Ramanujan constant. Robert J. Scherrer discusses in a paper the possibility that the values of π, e, γ, φ, and whole numbers could change over time. Other mathematical April Fools' jokes are also mentioned, such as a decomposition of the sphere into hexagons. There is a reference to an April Fools' joke about Fermat's conjecture, in which a well-known mathematician announced a counterproof. Another mathematician spread an April Fools' joke about the Riemann hypothesis through a mailing list. There is also a report about a fake article from Der Postillon, which claimed that German elementary school students do not master infinitesimal calculus. The Titanic and the NachDenkSeiten also published satirical articles about mathematical concepts and the Ukraine crisis. [Extracted from the article]

Starting from the role of listening comprehension in foreign language teaching, this paper illustrates the importance of phonological competence in general and prosody in particular in facilitating the auditory decoding process. Subsequently, the new phonological control scale in the companion volume of the CEFR is presented, which, in contrast to the previous scale, also emphasises the suprasegmental aspects of language. These are crucial in the receptive phase to break down the flow of language into smaller units of meaning, which are easier to process in short-term memory and thus support the decoding process. Finally, micro listening exercises are shown, created with authentic material and designed to promote receptive prosodic competence in German as a foreign language. [ABSTRACT FROM AUTHOR]

This special issue is devoted to the influence of Italian culture on the Antitrinitarian movements that spread through Europe during the early modern period. One of the objectives is to go back to the period preceding the activities of Lelio and Fausto Sozzini, and to consider the influences of various trends in the Italian thought of the 15th and 16th centuries that made a crucial contribution to shaping Antitrinitarian ideas about Biblical exegesis, spirituality, baptism and the Trinity. Some papers also cover the phase following the international establishment of Socinianism. While for the first half of the sixteenth century there is a tendency to underestimate the Italian contribution to European Antitrinitarianism, the exact opposite is true for the period between the end of the sixteenth and the seventeenth centuries. The perception of Antitrinitarianism changes completely and, following the international affirmation of the Sozzini, is often mistakenly identified with Socinianism, taking the part for the whole (as is still often the case today on a historiographical level).

Die Darstellung schließt mit einem Blick auf bisher erreichte Ergebnisse. In this paper we describe the implementation of a strictly task-based curriculum in a German language program at a Japanese university, illustrating the experiences, challenges and results from the point of view of the teachers involved. After a brief overview of the situation of teaching German at Japanese universities in general we explain the reasons leading to the development of the new program as well as the underlying theoretical considerations. The focus of this article is on the conflicts, which emerged over the course of the four years since the implementation of the task-based curriculum, and the combined efforts of the teaching staff to find solutions. Finally, we present an overview of the achievements to date. [ABSTRACT FROM AUTHOR]

The paper presents a study in which analytical and holistic ratings of participants' performances in the writing section of the digital TestDaF were investigated. It was investigated what influence the rating procedure has on the participants' results and to what extent the results of two different procedures are comparable. In the first study phase, performances were rated analytically by experienced raters, on each of six criteria using a 6-level grading scale. In the next phase, nine raters from the first (analytical) phase of the study applied the new (holistic) scale in assessing the same performances. In both (analytic and holistic) phases of assessment, differences in the quality of the ratings were examined according to both rating methods, and both inter-rater and intra-rater reliability were calculated separately for both rating methods. The analyses showed no significant differences between the rating methods in terms of rater behavior. However, the use of the holistic method tended to result in lower ratings.

This paper analyzes recordings of lessons that had to be digitised at short notice due to the pandemic. The data is taken from German lessons at the B1+ level for refugees interested in studying, which took place with the help of the web conferencing tool Cisco Webex. The evaluation of the data focuses on the different views of the lessons on the participants' screens and the resulting didactic consequences, on the transition from silent to cooperative work and on how teachers react to learners' questions and mistakes. The analysis of a longer sequence also shows how the transition from working on a form-focused exercise to free discussions of topics relevant to the learners' proceeds. [ABSTRACT FROM AUTHOR]

Job-related language skills in German are an important topic in today's educational policy - not only concerning integration within Germany (German as a Second Language), but also abroad (German as a Foreign Language). This is especially true in China, where the dual vocational system, which was introduced 35 years ago, is booming now, with some major German companies acting as trainers (e. g. BMW, Daimler, Schleich, Siemens and others). Consequently, at vocational schools and for in-company trainings, there is a growing need for suitable materials in order to teach German as a technical and job-related language. This paper presents the bilingual textbook German Language for Automobile Production in China (A2-B1), developed by students of the MA program "Intercultural German Studies / German as a Foreign Language" at the University of Göttingen in co-operation with the Goethe-Institut Beijing and the Association for German as a Foreign and Second Language (FaDaF). These materials are meant for courses at Chinese vocational schools or for in-service trainings). This paper focuses on the following aspects: the general framework and implementation of the project, the concept and didactic features of the textbook (textbook structure, regionalization and target group, the concept of functional multilingualism, scenario didactics and intercultural learning in technical and job-related language education), its sustainability and generally the adaptability of collaborative activities like textbook development to different contexts.

In this paper, we provide simple expressions for the permanent solutions corresponding to some oscillatory motions of two classes of Newtonian fluids with power-law dependence of viscosity on the pressure between two infinite horizontal parallel plates. The fluid motion is generated by the lower plate that applies an oscillatory shear stress to the fluid. Such solutions, which are lack in the existing literature, can be useful both for those who want to eliminate the transients from their experiments and as tests to verify numerical schemes that are developed to study complex unsteady flow problems of these fluids. The similar solutions corresponding to the motion due to a constant shear stress on the boundary are also determined and, contrary to our expectations, the shear stresses are constant on the whole flow domain although the associated velocity fields depend both of the spatial variable and the dimensionless pressure-viscosity coefficient. Finally, for validation, some comparative graphical illustrations are included and the convergence of starting solutions to the permanent solutions is graphically proved. Spatial profiles of starting solutions are also provided. [ABSTRACT FROM AUTHOR]

In this paper, we consider the well-known Vallis model for El Niño driven by an external excitation. The bifurcation studies on the driven Vallis model are conducted with different control parameters. Then we discuss about the taming of the Hopf bifurcation by varying the driving function. We could note that the system changes its state from stable steady state to oscillatory state and vice versa which is achieved by changing the driving function. Finally, two parameter bifurcation plots are derived to show that impact of the driving function on the system bifurcation points. [ABSTRACT FROM AUTHOR]

This paper presents an approximate analytical solution for the vertical dynamic impedance and shaft resistance of rectangular closed diaphragm walls (RCDWs) embedded in a homogeneous soil medium and resting on rock base. The vertical continuous displacement model for the steady-state response of RCDWs is proposed to ensure proper RCDWs-soil contact and satisfy the boundary condition of soil at infinite horizontal distance. The soil horizontal displacement is neglected and the effect is indirectly taken into account by the modification of soil modulus. The functional of system potential and kinetic energies is established via the soil and RCDWs displacement functions. The governing equations of the system and the relevant conditions are obtained and the vertical shaft resistance of RCDWs is established by employing Hamilton's variational principle for RCDWs-soil system and thin layer element, respectively. Some representative numerical examples are presented to portray the influences of soil core ratio, height–width ratio, diaphragm wall-soil stiffness ratio, and aspect ratio of RCDWs cross sections on the dynamic impedances and stiffness of the shaft resistance.

A relatively simple chaotic hyperjerk circuit, which is the modified chaotic hyperjerk system [Dalkiran and Sprott, IJBC 2016] is proposed and investigated in this paper. Only one semiconductor diode modelled the nonlinear function capable of rich and complex dynamical behaviours of the system. We investigate a new kind of behaviours name "bubbles of bifurcation" (referred as BsB hereafter) observed here for the first time in the hyperjerk system. An interesting phenomenon of mixed-mode bursting oscillations (MMBOs) is also investigated. The complex dynamics of the novel oscillator (such as MMBOs, BsB, offset boosting and multistability) with respect to its parameters and initial conditions are uncovered using bifurcation diagrams, Lyapunov exponents (LE) and phase portraits. As another interesting property of this circuit, some parameter regions are determined for the existence of coexisting BsB and the coexistence of asymmetric mixed-mode bursting oscillations. Let us emphasized that the complex phenomena observed in this work is very rare in the literature and henceforth merit dissemination. Finally, a physical circuit is constructed to demonstrate some experimental observation of MMBOs. [ABSTRACT FROM AUTHOR]

The main aim of this paper is, to obtain the analytical solution of the Riemann problem for a quasi-linear system of equations, which describe the one-dimensional unsteady flow of an ideal polytropic dusty gas in magnetogasdynamics without any restriction on the initial data. By using the Rankine-Hugoniot (R-H) and Lax conditions, the explicit expressions of elementary wave solutions (i. e., shock waves, simple waves and contact discontinuities) are derived. In the flow field, the velocity and density distributions for the compressive and rarefaction waves are discussed and shown graphically. It is also shown how the presence of small solid particles and magnetic field affect the velocity and density across the elementary waves. It is an interesting fact about this study that the results obtained for the Riemann problem are in closed form. [ABSTRACT FROM AUTHOR]

Evidently, some relaxation dynamics, e.g. exponential decays, are much more common in nature than others. Recently there have been attempts to explain this observation on the basis of "typicality of perturbations" with respect to their impact on expectation value dynamics. These theories suggest that a majority of the very numerous, possible Hamiltonian perturbations entail more or less the same type of alteration of the decay dynamics. Thus, in this paper, we study how the approach towards equilibrium in closed quantum systems is altered due to weak perturbations. To this end, we perform numerical experiments on a particular, exemplary spin system. We compare our numerical data to predictions from three particular theories. We find satisfying agreement in the weak perturbation regime for one of these approaches. [ABSTRACT FROM AUTHOR]

Loosely speaking, the concept of quantum typicality refers to the fact that a single pure state can imitate the full statistical ensemble. This fact has given rise to a rather simple but remarkably useful numerical approach to simulate the dynamics of quantum many-body systems, called dynamical quantum typicality (DQT). In this paper, we give a brief overview of selected applications of DQT, where particular emphasis is given to questions on transport and thermalization in low-dimensional lattice systems like chains or ladders of interacting spins or fermions. For these systems, we discuss that DQT provides an efficient means to obtain time-dependent equilibrium correlation functions for comparatively large Hilbert-space dimensions and long time scales, allowing the quantitative extraction of transport coefficients within the framework of, e. g., linear response theory (LRT). Furthermore, it is discussed that DQT can also be used to study the far-from-equilibrium dynamics resulting from sudden quench scenarios, where the initial state is a thermal Gibbs state of the pre-quench Hamiltonian. Eventually, we summarize a few combinations of DQT with other approaches such as numerical linked cluster expansions or projection operator techniques. In this way, we demonstrate the versatility of DQT. [ABSTRACT FROM AUTHOR]

In this paper, we have studied spinless fermions in four specific quasi one-dimensional systems that are known to host flat bands in the noninteracting limit: the triangle lattice, the stub lattice, the diamond lattice, and the diamond lattice with transverse hopping. The influence of the nearest neighbour interaction on the flat bands was investigated. We used exact diagonalization of finite size lattices employing the Lanczos technique and determine the single particle spectral functions of the interacting system. Our results are compared with mean field calculations. In the cases of the triangle lattice and the stub lattice we found that the flat bands become dispersive in the presence of a finite interaction. For the diamond lattice and the diamond lattice with transverse hopping, we demonstrated that the flat bands are robust under the influence of the interaction in certain parameter ranges. Such systems could be realised experimentally with cold atoms in optical lattices. [ABSTRACT FROM AUTHOR]

The genealogies of peoples and families developed in Europe during the modern period are prevalently studied by scholars from the perspective of the political history of ideas, with the aim of explaining the practical utility of genealogical works. These analyses do not foreground the aspect that is the focus of this paper: the fact that genealogical reconstructions are full of absurdities. They mix factual information, or information that may seem credible, with fabulous details, often false, sometimes ridiculous, in a word "incredible". This is all the more interesting since these texts were composed during the centuries in which scientific methods applied to historical research were developed. Using tools borrowed from cultural anthropology, this paper suggests an epistemological approach that takes into consideration the meaning and credibility of the genealogical materials in the still authoritative framework of the Historia Salutis, the unitary vision of human history as a fusion of the classical legacy and Biblical tradition.

The position paper by DMV, GDM, and MNU from November 23, 2022, deals with the acute shortage of mathematics teachers. The Education Report of 2022 and a model calculation by the KMK indicate a lack of mathematics teachers. Various measures to address the shortage are being discussed, such as recruiting additional students, establishing study places, and abolishing admission restrictions. The professional societies emphasize the importance of subject-specific and didactic educational components in these measures and propose nationally uniform minimum standards. It is recommended to conduct scientifically based training and further education programs and provide the necessary resources. [Extracted from the article]

Based on the example of formative evaluation data collected from the Chinese-German double degree program in mechanical engineering at the Chinese- German Technical Faculty in Qingdao (China), this paper discusses opportunities and challenges of integrating content and language learning as well as ways of optimizing preparatory and academic German language courses.

In this paper, I will first review the history of advanced training for Chinese German teachers in the first phase (from 2006 to 2009) and the second phase of the development of the Department German Studies in China. The current situation of the young Chinese German teachers is presented and analyzed by the result of a research based on the newly founded departments of German Studies from 2000 to 2009 at 40 universities. This is also considered to be an argument for the second phase (2010-2017) of the advanced training, namely that the training courses should be aimed at special fields of German Studies. After the report on the second phase of the advanced training, I try to evaluate the impact of the training courses by analyzing comments in video interviews as well as e-mail surveys in 2016. By comparing the results conducted with the same target group in 2009 and 2017, the continuous impact of the teacher training can be brought to light. [ABSTRACT FROM AUTHOR]

This paper first introduces the 2 plus 3 program at the ZUST. Then the author probes into the question what the greatest difficulties are, despite of the apparent attractiveness of the double degree program. The results of a questionnaire show that both the intercultural differences and the lack of vocabulary significantly complicate the students' daily learning. To overcome the abovementioned difficulties, effective measures have already been taken in German lessons. The German language teaching experience in ZUST suggests that application orientation in German lessons is the key to its success. In the end, further considerations for improving the program are briefly explained. [ABSTRACT FROM AUTHOR]

The present paper focuses on teacher training of German as a foreign language in China. On the background of a long historical development and the tendency to speak multiple languages at present, teaching German language is experiencing a boom in China today. At the same time the adaptation to the great need of qualified teaching staff, the improvement of teaching content and methods of learning as well as the use of modern teaching methods are important factors for sustainable development.

German Studies in China is a new-born academic field where philological education takes the first place and focuses on training of language specialists. With far-reaching economic reforms and the intensification of China's cooperation with German-speaking countries, the philological German Studies oriented on language education has been slowing to meet the new demands of the labor market and falling gradually into the crisis. Based on the training profile of students majoring in German Studies, this paper examines the crisis and further discusses the ways of modernizing Chinese German Studies. [ABSTRACT FROM AUTHOR]
