  text: We investigate generalisations of 1-factorisations and hyperfactorisations
    of the complete graph $K_{2n}$. We show that they are special subsets of the association
    scheme obtained from the Gelfand pair $(S_{2n},S_2 \wr S_n)$. This unifies and
    extends results by Cameron (1976) and gives rise to new existence and non-existence
    results. Our methods involve working in the group algebra $\mathbb{C}[S_{2n}]$
    and using the representation theory of $S_{2n}$.

  text: "In this work, we build a bridge between the Pólya--Schur program and Voiculescu's
    free probability theory. A cornerstone of the former is the Pólya--Benz Theorem,
    classifying a central family of real-root preserving operators on the space of
    polynomials, as those given by $f(\\partial_z)$ for a Laguerre--Pólya function
    $f$ and the derivative operator $\\partial_{z}$. We prove that any free (additive)
    infinitely divisible distribution can be attained as the weak limit of root distributions
    of Appell polynomials $f_n(\\partial_z)z^n$ as $n\\to\\infty$, for a suitably
    chosen sequence $f_n$ of Laguerre--Pólya functions.\r\n  Such questions on the
    (global) limiting distributions of real rooted polynomials belong to the active
    research area of finite free probability. In contrast to its standard tools, our
    approach allows for non-compactly supported limiting distributions, (barely) complex
    rooted polynomials and even provides the full microscopic description of the roots.
    Moreover, we extend our results to differential operators generating free multiplicative
    infinitely divisible distributions, to the rectangular free convolution, and to
    $f_n(\\partial_z)p_n$ for real rooted polynomials $p_n$, implying a generalization
    of the recent connections between the heat flow and free Brownian motion to any
    free Lévy process.\r\n  As corollaries, we identify free stable distributions
    by choosing $f_n$ to be a fixed rescaled Laguerre--Pólya function, and we prove
    various convergence results on the zero distributions of Jensen polynomials, e.g.
    the limiting root distribution of Jensen polynomial of the Riemann $Ξ$-function
    is given by the Cauchy distribution."

  text: "We generalize intersection numbers for combinatorial designs to designs in
    finite meet-semilattices satisfying suitable regularity conditions. While designs
    in regular semilattices go back to Delsarte, our regularity assumptions are weaker
    than his and need not give rise to an association scheme. In this framework, we
    extend Mendelsohn's equations, prove a generalized Singleton bound with Steiner
    systems as equality cases, and determine the block intersection distribution at
    any block of a Steiner system. In particular, this distribution is independent
    of the chosen block.\r\n  Specializing to several classical semilattice families,
    our results recover a number of well-known distributions in coding and design
    theory. In the Hamming and the $q$-Hamming (or bilinear forms) schemes, they give
    the local distance distributions of MDS and MRD codes, respectively. In the Johnson
    and $q$-Johnson (or Graßmann) schemes, they reproduce the block intersection distribution
    of classical and $q$-analog Steiner systems, equivalently the distance distribution
    of diameter-perfect constant-weight codes and diameter-perfect constant-dimension
    subspace codes. For the $q$-Johnson schemes, to the best of our knowledge, this
    result is new. As a further illustration, we apply our theory to designs of perfect
    matchings.\r\n  Our approach provides a unified treatment of these cases in the
    strongest form known in the literature, determining the distribution relative
    to each individual block or codeword, without averaging and without linearity
    or additivity assumptions. Moreover, it identifies the natural double-counting
    objects underlying these distributions, leading to formulas in the regularity
    parameters of the semilattice and avoiding the more cumbersome expressions that
    arise in eigenvalue-based approaches via the ambient association scheme."

  text: AnnoPy ist ein digitales Werkzeug, um kollaborativ Texte zu lesen, zu erschließen
    und zu analysieren. Es ist für die Präsenzlehre konzipiert und unterstützt Lehrende
    dabei, den Übergang von der individuellen Auseinandersetzung mit wissenschaftlichen
    Texten hin zu einer kollaborativ-sozialen Aushandlung des Gelesenen in Lehrveranstaltungen
    zu organisieren und zu strukturieren. Im Beitrag wird das digitale kollaborative
    Tool AnnoPy vorgestellt und gezeigt, welche Potenziale sich für die Analyse von
    Daten über Lernende durch die Integration von KI-basierter Learning Analytics
    in das Tool ergeben. Anhand von exemplarischen Daten aus einer Vorlesung der Mathematikdidaktik
    wird zunächst vorgestellt, wie in AnnoPy eine algorithmisch-händische Analyse
    und Datenauswertung erfolgte, um dann diese Art der Auswertung mit einer KI-gestützten
    Auswertung, bei der ein MCP-Server eingebunden wurde, zu vergleichen.

  text: This qualitative case study investigates how automated feedback from a widely
    accessible digital curriculum resource influences students’ mathematics learning.
    Drawing on a dialogic feedback framework, the study analyzes students’ feedback
    processes in an ecologically valid learning context. Grounded in a sociocultural
    perspective, the framework integrates Carless’ dialogic conceptualization of feedback,
    Shute’s feedback typology, and Vergnaud’s scheme theory. Eight eighth-graders
    from a German secondary school worked individually on percentage problems at home,
    video-recorded via online conferencing. Data included screen recordings and think-aloud
    protocols, which were analyzed using qualitative text analysis. Results reveal
    large individual differences in feedback processes—students vary in when and how
    they access feedback messages and how they make sense of them. Successfully solving
    a task after feedback does not always indicate understanding; in some cases, feedback
    aided procedural completion without conceptual insight. The effectiveness depended
    on the alignment between task design, feedback message content, and students’
    actual difficulties. The study concludes that qualitative analysis of feedback
    processes with digital technologies in ecologically valid settings is necessary
    to target specific student difficulties and promote learning.</jats:p>

  text: '<jats:title>Abstract</jats:title><jats:p>In this symposium we investigate
    students’ agency of selecting and using (digital) resources for developing their
    own learning paths. For that, we first review the literature related to students’
    selection and use of resources in mathematics education in different pedagogical
    settings (presentation 1). Second, we develop insights from the different studies
    that participate in this symposium (presentation 2–6), at school as well as at
    university level. Results show that attempts have been made to provide students
    opportunities to develop agency of their mathematics learning, in particular with
    the development and provision of numerous digital tools and learning resources
    at university level and related to innovative pedagogical approaches. At the same
    time, it is not obvious how these tools and resources help students to develop
    deeper conceptual understandings. Certainly, students often ‘demand’ more student-centered
    and autonomous education approaches (e.g., at university level), also in mathematics
    education. Further, it seems that authentic problem-based education approaches
    are more motivating for students. These ‘innovative’ approaches necessitate particular
    types of structure and support for students. Moreover, they require different
    ways of providing resources that students can and want to interact with, and that
    help students to navigate through the curriculum to develop their own learning
    paths. At the same time, teachers also need support on how to orchestrate student
    learning with the available resources in such environments, so to be able to attend
    to students’ individual needs. The symposium comprised altogether six presentations:</jats:p><jats:p>Birgit

  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>Statistics and machine
    learning are critical because they play an essential role in our everyday lives
    and the careers we may pursue in the future. It may be beneficial to introduce
    machine learning, such as decision trees (DTs), at an early stage of education.
    The data-based construction of DTs is an example of a machine learning process,
    which can be addressed in mathematics or statistics teaching because of relatively
    low prior knowledge requirements. This paper focuses on investigating how sixth-grade
    students create and evaluate data-based DTs. The basis is a teaching unit that
    aims to lay the foundation for machine learning and enhance students’ understanding
    of the process. We investigate students’ processes in detail while they build
    DTs with data cards about food items to predict whether a new item is recommendable.
    After the teaching unit, an interview study examines students’ strategies for
    creating decision trees. The findings contribute to understanding students’ learning
    processes and the challenges when working with decision trees.</jats:p>"

  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>This study explores
    how high school students construct decision trees using data cards and the software
    CODAP (codap.concord.org) in interviews after attending a teaching unit. We conceptualized
    data-based decision tree construction using nine key aspects that we intended
    to teach, tested variations of two design elements in teaching, and analyzed the
    interviews qualitatively to compare student behavior to intended outcomes. We
    found high alignment to intentions but also deviations in data activities and
    informal or context-based rather than data-based reasoning. The design element
    of context-free (blinded) data seems to enhance data-based reasoning, while the
    design element of data card use showed diagnostic potential.</jats:p>"

  text: "Given a sequence of polynomials $(P_n)_{n \\in \\mathbb{N}}$ with only\r\nnonpositive
    zeros, the aim of this article is to present a user-friendly\r\napproach for determining
    the limiting zero distribution of $P_n$ as\r\n$\\mathrm{deg}\\, P_n \\to \\infty$.
    The method is based on establishing an\r\nequivalence between the existence of
    a limiting empirical zero distribution\r\n$\\mu$ and the existence of an exponential
    profile $g$ associated with the\r\ncoefficients of the polynomials $(P_n)_{n \\in
    \\mathbb{N}}$. The exponential\r\nprofile $g$, which can be roughly described
    by $[z^k]P_n(z) \\approx \\exp(n\r\ng(k/n))$, offers a direct route to computing
    the Cauchy transform $G$ of $\\mu$:\r\nthe functions $t \\mapsto tG(t)$ and $\\alpha
    \\mapsto \\exp(-g'(\\alpha))$ are\r\nmutual inverses. This relationship, in various
    forms, has previously appeared\r\nin the literature, most notably in the paper
    [Van Assche, Fano and Ortolani,\r\nSIAM J. Math. Anal., 1987].\r\n  As a first
    contribution, we present a self-contained probabilistic proof of\r\nthis equivalence
    by representing the polynomials as generating functions of\r\nsums of independent
    Bernoulli random variables. This probabilistic framework\r\nnaturally lends itself
    to tools from large deviation theory, such as the\r\nexponential change of measure.
    The resulting theorems generalize and unify a\r\nrange of previously known results,
    which were traditionally established through\r\nanalytic or combinatorial methods.\r\n
    \ Secondly, using the profile-based approach, we investigate how the\r\nexponential
    profile and the limiting zero distribution behave under certain\r\noperations
    on polynomials, including finite free convolutions, Hadamard\r\nproducts, and
    repeated differentiation. In particular, our approach yields new\r\nproofs of
    the convergence results `$\\boxplus_n \\to \\boxplus$' and `$\\boxtimes_n\r\n\\to
    \\boxtimes$', extending them to cases where the distributions are not\r\nnecessarily
    compactly supported."
