description: Let $X$ be a completely regular space. For a non-vanishing self-adjoint Banach subalgebra $H$ of $C_B(X)$ which has local units we construct the spectrum $\mathfrak{sp}(H)$ of $H$ as an open subspace of the Stone-Cech compactification of $X$ which contains $X$ as a dense subspace. The construction of $\mathfrak{sp}(H)$ is simple. This enables us to study certain properties of $\mathfrak{sp}(H)$, among them are various compactness and connectedness properties. In particular, we find necessary and sufficient conditions in terms of either $H$ or $X$ under which $\mathfrak{sp}(H)$ is connected, locally connected and pseudocompact, strongly zero-dimensional, basically disconnected, extremally disconnected, or an $F$-space.

description: Die vorliegende Arbeit befasst sich mit der Frage, wie die Schule Kinder unterstützen kann, bei denen ein Elternteil gestorben ist. Dabei ist zentral, welche Hilfestellungen von den Kindern und dem verbleibenden Elternteil von der Schule gewünscht wird und inwiefern sich die Tabuisierung der Gesellschaft zur Thematik Tod und Trauer in der Schule widerspiegelt.
 Im Theorieteil der Arbeit wird vorerst die Bindungstheorie vorgestellt, da sie die wichtigste Ressource in der Trauerverarbeitung darstellt. Anschliessend wird die Trauer allgemein behandelt und drei Modelle des Trauerprozesses erörtert. Die Begegnung von Kindern mit dem Tod, sowie die kindliche Trauerverarbeitung wird im Anschluss vorgestellt. Zum Schluss folgt eine Einleitung zum Umgang mit dem Tod in der Schule.
 Mit Hilfe von Leitfadeninterviews befragten wir betroffene Kinder, deren Mütter und einen Experten zum Thema Trauerarbeit in der Schule. Die Daten wurden mittels qualitativer Inhaltsanalyse ausgewertet und interpretiert. Diese dienten der Beantwortung der Fragestellungen.
 Zum Schluss der Arbeit präsentieren wir einen kurzen Leitfaden mit den wichtigsten Nennungen der Kinder, der Eltern, aber auch der Literatur und des Experten. Ebenfalls darin enthalten sind konkrete Ideen für Rituale oder Hilfestellungen, welche die Lehrpersonen den betroffenen Familien bieten könnten. Ausserdem wurde eine Liste mit Literaturvorschlägen zum Thema Tod, für Kinder und Erwachsene, sowie wichtige Links zusammengestellt.
One-Loop Radiative Correction to the Triple Higgs Coupling in the Higgs Singlet Model

description: Though the 125 GeV Higgs boson is consistent with the standard model (SM) prediction until now, the triple Higgs coupling can deviate from the SM value in the physics beyond the SM (BSM). In this paper, the radiative correction to the triple Higgs coupling is investigated in the minimal extension of the SM by adding a real gauge singlet scalar. In this model there are two scalars $h$ and $H$, and both of them are mixing states of the doublet and singlet. Provided that the mixing angle is set to be zero, namely the SM limit, $h$ is the pure left-over of the doublet and its behaviour is the same as that of the SM at the tree level. However the loop corrections can alter $h$-related couplings. In this SM limit case, the effect of the singlet $H$ may show up in the $h$-related couplings, especially the triple $h$ coupling. Our numerical results show that the deviation is sizable. For $λ_{Φ{S}}=1$ (see the text for definition), the deviation $δ_{hhh}^{(1)}$ around threshold can be more than $20\%$ if mass of the new scalar is light. For $λ_{Φ{S}}=1.5,3$, the deviation $δ_{hhh}^{(1)}$ can reach above $30\%$ in the vicinity of threshold. For $λ_{Φ{S}}=-1$, $m_H$ can be light. The deviation $δ_{hhh}^{(1)}$ is negative in this case and can be even $-50\%$ in the threshold enhanced region. The radiative correction for the $hZZ$ coupling is from the counter-term, which is universal in this model and always with negative sign. $δ_{hZZ}^{(1)}$ is independent of the sign of $λ_{Φ{S}}$ and its typical size is $-0.2\%\sim-2\%$. When combining $hhh$ and $hZZ$ precision measurements together, parameter space of this model can be probed well including the sign and size of $λ_{Φ{S}}$.

title: CRISIS TRANSMITTING EFFECTS DETECTION AND EARLY WARNING SYSTEMS DEVELOPMENT FOR CHINA’S FINANCIAL MARKETS
Creators: name: Wang, Peiwan
Publisher: name: University of Liverpool Repository
Year: 2022

description: In the background of China’s economic development mode being focused the worldwide attention, there is a growing trend to study the risk transmission pattern and the crisis forecasting mechanism for China’s financial markets by domestic and global academics. The study progress, however, is observed to be affected by two gaping research problems: 1) few studies construct comparative contagion models and integrated crisis forecasting systems for China’s financial markets and 2) current econometric models hired to the risk spreading effects detection and the financial crisis forecasts are yet deterministically investigated in terms of the effectiveness on China. To fill the gaps, this research proposes two hybrid contagion models and prototypes the early warning systems with motivations of first analyzing the crisis linkages and transmission channels across domestic markets in hierarchical frameworks, and then predicting the market turbulence by integrating the crisis identifying techniques and time-dependent deep learning neuron networks. To accomplish our aims, the full project is progressed in phases by solving four technical challenges that portray two literature gaps of A) the crisis identification on the basis of price volatility state distinction, B) the decomposition for multivariate correlated patterns to infer the interdependence structure and risk spillover dynamics respectively, C) the real-time warning signals generation in comparison of between traditional and stylized predictive models and D) the contagion information fusion in the EWS frameworks to distinguish the leading indicators from between internal macroeconomic factors and external risk transmitters in statistical validation metrics. The research mainly contributes to the comparative analysis on financial contagion effects detection and market turbulence prediction through the hybrid model innovations for CM and EWS development, and meanwhile brings practical significance to improve the risk management in investing activities and support the crisis prevention in policy-making. In addition, the model experimented results corroborate the China-characterized mode on risk transmissions and crisis warnings that 1) the stocks and real estate markets are verified to play the central role among risk transmitters, while the managed floating foreign exchange rate and the non-fully liberalized bond market are peripheral during the crisis; and 2) the all-round opening up policy increases the possibility of domestic security markets being exposed to external risk factors, especially relating to the cash flows, energy commodities and precious metals.

The challenging task of determining star formation rates: the case of a massive stellar burst in the brightest cluster galaxy of Phoenix galaxy cluster

description: Star formation in galaxies at the center of cooling-flow galaxy clusters is an important phenomenon in the context of formation and evolution of massive galaxies in the Universe. Yet, star formation rates (SFRs) in such systems continue to be elusive. We use our Bayesian-motivated spectral energy distribution (SED)-fitting code, BAYESCOOL, to estimate the plausible SFR values in the brightest cluster galaxy of a massive, X-ray luminous galaxy cluster, Phoenix. Previous studies of Phoenix have resulted in the highest measurement of SFR for any galaxy, with the estimates reaching up to 1000 solar masses/yr. However, a very small number of models have been considered in those studies. BAYESCOOL allows us to probe a large parameter space. We consider two models for star formation history, instantaneous bursts and continuous star formation, a wide range of ages for the old and the young stellar population, along with other discrete parameters, such as the initial mass function, metallicities, internal extinction and extinction law. We find that in the absence of any prior except that the maximum cooling rate < 3000 solar masses/yr, the SFR lies in the range (2230-2890) solar masses/yr. If we impose an observational prior on the internal extinction, E(B-V) < 0.6, the best-fit SFR lies in (454-494) solar masses/yr, and we consider this as the most probable range of SFR values for Phoenix. The SFR dependence on the extinction is a reflection of the standard age-extinction degeneracy, which can be overcome by using a prior on one of the two quantities in question.

description: Pentadiamond is a carbon allotrope consisting of hybrid sp2 and sp3 atoms, which has been predicted to be stable and synthesizable. In this work we employ first-principles calculations to explore the electronic structure, optical characteristics, mechanical response and lattice thermal conductivity of pentadiamond, performing a direct comparison with the corresponding properties in diamond. The HSE06 density functional predicts indirect electronic band gaps for pentadiamond and diamond with values of 3.58 eV and 5.27 eV, respectively. Results for optical characteristics reveal pentadiamond's large absorption in the middle UV region, where diamond does not absorb light, consistent with the smaller band gap of pentadiamond. The elastic modulus and tensile strength of pentadiamond are found to be 496 GPa and 60 GPa, respectively, considerably lower than the corresponding values for diamond. The lattice thermal conductivity is examined by solving the Boltzmann transport equation, with anharmonic force constants evaluated via state-of-the-art machine-learning interatomic potentials. We predict a thermal conductivity of 427 W/m-K for pentadiamond, less than one fifth of the corresponding quantity for diamond. Our results provide a useful vision of the intrinsic properties of pentadiamond, but also highlight some of its disadvantages in mechanical strength and heat conduction when compared to diamond.

Die Autorinnen erschlossen Theorien zur (heil-)pädagogischen Beziehung. Zudem wurden sieben Interviews mit sachverständigen Lehrpersonen und ein Interview mit einem Experten für die schulische Integration von Kindern mit Verhaltensauffälligkeit durchgeführt und mittels qualitativer Inhaltsanalyse ausgewertet. Die Ergebnisse zeigen förderliche Aspekte der pädagogischen Beziehungsgestaltung, welche durch die verschiedenen Forschungszugänge herausgearbeitet werden konnten. Die Aspekte sind theoretisch fundiert und für einen Transfer in die Praxis fassbar beschrieben. Sie bilden die Dimensionen „Nähe zum Kind mit Verhaltensauffälligkeit“, „pädagogische Interaktion mit dem Kind mit Verhaltensauffälligkeit“, „reflexive Distanz zur pädagogischen Beziehung“ und „Einstellungen“.
Archives as artifact for art analysis: a study of the benefits of including archival material in art exhibits
Creators: name: Biesiadecki, John
Publisher: name: No Publisher Supplied
Year: 2020

description: Upon examining definitions of Cultural Heritage as proposed by some of the discipline’s primary scholars, one can derive the necessary classifications and objectives that make certain institutions examples of cultural heritage institutions. By virtue of promoting the education of art history and art analysis, the objectives of art museums and exhibits align with the objectives of cultural heritage institutions, thus making art museums and exhibits examples of cultural heritage institutions. This paper proposes that the incorporation of relevant archival material into art exhibits can promote art history and art analysis, thus aiding art museums and art exhibits achieve the status of cultural heritage institution. This proposal is supported by two case studies exhibiting the art of Thomas Cole and other artists associated with The Hudson River School of American landscape painters. One case study is on the Thomas Cole National Historic Site which incorporates archival material into its gallery spaces and the other case study is on the Pennsylvania Academy of Fine Arts’ exhibit on the Schuylkill River School of American landscape painters which does not incorporate archival material into its gallery spaces. Comparing and contrasting the effectiveness of both exhibits’ ability to provide comprehensive art analysis reveals that an art exhibit with information from archival material better promotes the objectives of the exhibit, thus elevating the exhibit to the status of a cultural heritage institution.

description: Estimations of global glacier mass changes over the course of the 20th century require automated initialization methods, allowing the reconstruction of past glacier states from limited information. In a previous study, we developed a method to initialize the Open Global Glacier Model (OGGM) from past climate information and present-day geometry alone. Tested in an idealized framework, this method aimed to quantify how much information present-day glacier geometry carries about past glacier states. The method was not applied to real-world cases, and therefore, the results were not comparable with observations. This study closes the gap to real-world cases by introducing a glacier-specific calibration of the mass balance model. This procedure ensures that the modeled present-day geometry matches the observed area and that the past glacier evolution is consistent with bias-corrected past climate time series. We apply the method to 517 glaciers, spread globally, for which either mass balance observations or length records are available, and compare the observations to the modeled reconstructed glacier changes. For the validation of the initialization method, we use multiple measures of reconstruction skill (e.g., MBE, RMSE, and correlation). We find that the modeled mass balances and glacier lengths are in good agreement with the observations, especially for glaciers with many observation years. These results open the door to a future global application.

description: Promising searches for new physics beyond the current standard model (SM) of particle physics are feasible through isotope-shift spectroscopy, which is sensitive to a hypothetical fifth force between the neutrons of the nucleus and the electrons of the shell. Such an interaction would be mediated by a new particle which could in principle be associated with dark matter. In so-called King plots, the mass-scaled frequency shifts of two optical transitions are plotted against each other for a series of isotopes. Subtle deviations from the expected linearity could reveal such a fifth force. Here, we study experimentally and theoretically six transitions in highly charged ions of Ca, an element with five stable isotopes of zero nuclear spin. Some of the transitions are suitable for upcoming high-precision coherent laser spectroscopy and optical clocks. Our results provide a sufficient number of clock transitions for - in combination with those of singly charged Ca+ - application of the generalized King plot method. This will allow future high-precision measurements to remove higher-order SM-related nonlinearities and open a door to yet more sensitive searches for unknown forces and particles.

description: Statistics has made tremendous advances since the times of Fisher, Neyman, Jeffreys, and others, but the fundamental and practically relevant questions about probability and inference that puzzled our founding fathers remain unanswered. To bridge this gap, I propose to look beyond the two dominating schools of thought and ask the following three questions: what do scientists need out of statistics, do the existing frameworks meet these needs, and, if not, how to fill the void? To the first question, I contend that scientists seek to convert their data, posited statistical model, etc., into calibrated degrees of belief about quantities of interest. To the second question, I argue that any framework that returns additive beliefs, i.e., probabilities, necessarily suffers from {\em false confidence}---certain false hypotheses tend to be assigned high probability---and, therefore, risks systematic bias. This reveals the fundamental importance of {\em non-additive beliefs} in the context of statistical inference. But non-additivity alone is not enough so, to the third question, I offer a sufficient condition, called {\em validity}, for avoiding false confidence, and present a framework, based on random sets and belief functions, that provably meets this condition. Finally, I discuss characterizations of p-values and confidence intervals in terms of valid non-additive beliefs, which imply that users of these classical procedures are already following the proposed framework without knowing it.

Masterarbeit

description: Im Rahmen des Masterstudiengangs Sonderpädagogik an der Interkantonalen Hochschule für Heilpädagogik wurde diese Arbeit zum Thema Integration von Kindern mit Verhaltensstörungen verfasst. Sie beschäftigt sich anhand von Literaturrecherche mit dem Phänomen der Verhaltensstörungen, möglichen Ursachen und dem Umgang mit solchen Auffälligkeiten in der Schule. Dabei soll besonders die Beziehung zwischen der Lehrperson und dem Kind mit Förderbedarf im emotional-sozialen Bereich betrachtet werden. Im Vordergrund steht dabei die These, dass eine wertschätzende Beziehung die Integration positiv unterstützt und sogar einen zentralen Gelingesfaktor darstellt. Die umfassende Beschäftigung mit aktueller und relevanter Literatur hat diese These weitgehend bestätigt. Mit Hilfe von qualitativer Sozialforschung sollte diese Hypothese danach "im Feld" überprüft werden. Anhand von Leitfadeninterviews wurde alsdann erforscht, ob auch die Fachpersonen für diese Frage, also Klassenlehrpersonen der Regelklasse, dieser Annahme zustimmen können. Die Auswertung der Daten erfolgte durch die qualitative Inhaltsanalyse.

Given the constant growth in data storage capacities available due to advances in technology, the analysis of high-dimensional data is becoming increasingly important in modern day statistics. One of the challenges faced with high-dimensional data is graphical visualization which allows the relationship(s) between response and predictor variables to be detected. Methods such as Sliced Inverse Regression (SIR), Sliced Average Variance Estimation (SAVE) and Principal Hessian Directions (PHD) provide a way to overcome this problem by reducing the dimension of the data without loss of information. However, each of these methods has respective advantages and disadvantages. The purpose of this thesis is to provide advances to the combination of dimension reduction methods which can provide significant improvement to estimation in many contexts. The contribution of this thesis is three-fold. First, a new approach to combining dimension reduction methods is proposed which involves the iterative application of these methods. This approach is applicable to both continuous and discrete response data. Second, a novel way of choosing dimension reduction parameters based on influence measures is introduced, as the number of parameters can increase when these methods are combined. Third, given that maximum ‘separation’ of classes is of major benefit in discriminant analysis, the choice of parameters is considered based on new visual and quantitative measures of separation.

description: This work is devoted to investigating the behaviour of invariant algebraic curves for the two dimensional Lotka-Volterra systems and examining almost a geometrical approach for finding invariant algebraic surfaces in three dimensional Lotka-Volterra systems. We consider the twenty three cases of invariant algebraic curves found in Ollagnier (2001) of the two dimensional Lotka-Volterra system in the complex plane and then we explain the geometric nature of each curve, especially at the critical points of the mentioned system. We also investigate the local integrability of two dimensional Lotka-Volterra systems at its critical points using the monodromy method which we extend to use the behaviour of some of the invariant algebraic curves mentioned above. Finally, we investigate invariant algebraic surfaces in three dimensional Lotka- Volterra systems by a geometrical method related with the intersection multiplicity of algebraic surfaces with the axes including the lines at infinity. We will classify both linear and quadratic invariant algebraic surfaces under some assumptions and commence a study of the cubic surfaces.

description: Since the discovery of the Higgs boson at the Large Hadron Collider, a future electron-position collider has been proposed for precisely studying its properties. We investigate the production of the Higgs boson at such an $e^+e^-$ collider associated with a $Z$ boson, and calculate for the first time the mixed QCD-electroweak corrections to the total cross sections. We provide an approximate analytic formula for the cross section and show that it reproduces the exact numeric results rather well for collider energies up to 350 GeV. We also provide numeric results for $\sqrt{s}=500$ GeV, where the approximate formula is no longer valid. We find that the $\mathcal{O}(αα_s)$ corrections amount to a 1.3% increase of the cross section for a center-of-mass energy around 240 GeV. This is significantly larger than the expected experimental accuracy and has to be included for extracting the properties of the Higgs boson from the measurements of the cross sections in the future.

Breit-Wigner approximation for propagators of mixed unstable states

Year: 2016
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: For systems of unstable particles that mix with each other, an approximation of the fully momentum-dependent propagator matrix is presented in terms of a sum of simple Breit-Wigner propagators that are multiplied with finite on-shell wave function normalisation factors. The latter are evaluated at the complex poles of the propagators. The pole structure of general propagator matrices is carefully analysed, and it is demonstrated that in the proposed approximation imaginary parts arising from absorptive parts of loop integrals are properly taken into account. Applying the formalism to the neutral MSSM Higgs sector with complex parameters, very good numerical agreement is found between cross sections based on the full propagators and the corresponding cross sections based on the described approximation. The proposed approach does not only technically simplify the treatment of propagators with non-vanishing off-diagonal contributions, it is shown that it can also facilitate an improved theoretical prediction of the considered observables via a more precise implementation of the total widths of the involved particles. It is also well-suited for the incorporation of interference effects arising from overlapping resonances.

description: Gathering information, especially about the immediately surrounding world, is a central aspect of any smart device, whether it is a robot, a partially autonomous vehicle, or a mobile handheld device. The consequential use of electrical sensors always implies the need to filter the imperfect sensor data output in order to gain reliable information. While the challenge of perception and cognition in machines is not a new one, new technology constantly opens up new possibilities and challenges. This is stressed further by the advent of cheap sensor technology and the possibility to use a multitude of small sensors, with the simultaneous constraint of limited resources on mobile, battery-powered computing devices. In this work, stochastic methods are used to filter sensor data, which is gathered by mobile devices, to model the devices' location and eventually also relevant parts of their dynamic environment. This is done with a focus on online algorithms and computation on these mobile devices themselves, which implies limited available processing power and the necessity for computational efficiency. This dissertation's purpose is to impart a better understanding about the conception and design of stochastic filtering solutions, to propose localization algorithms beyond the current state of the art, and to show the use of simultaneous localization and mapping algorithms in the context of cooperatively estimating the surrounding world of a team of robots in a fast changing, dynamic environment. To achieve these goals, the concepts are depicted in multiple application scenarios, design choices and their implications systematically cover all aspects of sensing and estimation, and the proposed systems are evaluated in real-world experiments on humanoid robots and other mobile devices.

description: We study formation and long-term evolution of a circumstellar disk in a collapsing molecular cloud core using a resistive magnetohydrodynamic simulation. While the formed circumstellar disk is initially small, it grows as accretion continues and its radius becomes as large as 200 AUs toward the end of the Class-I phase. A pair of grand-design spiral arms form due to gravitational instability in the disk, and they transfer angular momentum in the highly resistive disk. Although the spiral arms disappear in a few rotations as expected in a classical theory, new spiral arms form recurrently as the disk soon becomes unstable again by gas accretion. Such recurrent spiral arms persist throughout the Class-0 and I phase. We then perform synthetic observations and compare our model with a recent high-resolution observation of a young stellar object Elias 2-27, whose circumstellar disk has grand design spiral arms. We find good agreement between our theoretical model and the observation. Our model suggests that the grand design spiral arms around Elias 2-27 are consistent with material arms formed by gravitational instability. If such spiral arms commonly exist in young circumstellar disks, it implies that young circumstellar disks are considerably massive and gravitational instability is the key process of angular momentum transport.

description: Im Südtirol beeinflussen die geographischen, geschichtlichen, sowie die gesetzlichen Gegebenheiten massgebend den schulischen Alltag. Diese Aspekte werden durchleuchtet und danach der Begriff Inklusion definiert. Die Frage lautet: „Welche Voraussetzungen sind in der Grundschule Welsberg vorhanden, damit Inklusion gelingt?“ Am Beispiel „Grundschule Welsberg im Pustertal“ wird dieser Frage nachgegangen und auch geforscht, wie sich die 1977 verordnete Integration aller Schüler zur heutigen Inklusion weiterentwickelt hat. Anhand der Literaturrecherche, Beobachtungen vor Ort, sowie Experten-Interviews werden Vergleiche hergestellt und analysiert. Ausserdem werden die Aussagen aus den Experten-Interviews einer qualitativen Inhaltsanalyse unterzogen, bearbeitet und ausgewertet. Abschliessend wird diskutiert, ob und wie dieses System bei uns eingesetzt werden könnte.

The global derived period map

description: Abstract. We develop the global period map in the context of derived geometry, generalising Griffiths' classical period map as well as the infinitesimal derived period map. We begin by constructing the derived period domain which classifies Hodge filtrations and enhances the classical period domain. We analyze the monodromy action. Then we associate to any polarized smooth projective map of derived stacks a canonical morphism of derived analytic stacks from the base into the quotient of the derived period domain by monodromy. We conclude the paper by discussing a few examples and a derived Torelli problem. In the appendix we describe how to present derived analytic Artin stacks as hypergroupoids, which may be of independent interest.

Mathematik lernen und unterrichten in der Grundschule

description: Anlass für diesen Beitrag ist die Frage, was in der Mathematikdidaktik seit Verabschiedung der Bildungsstandards 2004 eigentlich erreicht wurde und welche Forschungslücken zu konstatieren sind. Mein Blick auf dieses Thema ist ein spezifischer: Als Sonderpädagogin blicke ich primär psychologisch auf das individuelle Lernen, als Soziologin dann sekundär auf dieses individuelle Lernen im sozialen Umfeld. Mit diesem Fokus betrachte ich die prozessbezogenen Kompetenzbereiche der Bildungsstandards. Diese Konzentration auf die allgemeinen Kompetenzen ist vorrangig motiviert als Gegengewicht zu dem häufig inhaltlichen Blick, in welchem die prozessbezogenen Kompetenzen lediglich begleitende Funktion einnehmen. Alle fünf Kompetenzbereiche sollen betrachtet werden. Ausgehend von den formulierten Erwartungen in den Bildungsstandards werden wenige Hauptpunkte des jeweiligen Gebietes thematisiert und grundlegende offene Fragen aufgeworfen. Insofern warne ich davor, Vollständigkeit zu erwarten.

Measurement of the total and differential inclusive B+ hadron cross sections in pp collisions at sqrt(s) = 13 TeV

description: The differential cross sections for inclusive production of B+ hadrons are measured as a function of the B+ transverse momentum pT[B] and rapidity y[B] in pp collisions at a centre-of-mass energy of 13 TeV, using data collected by the CMS experiment that correspond to an integrated luminosity of 49.4 inverse picobarns. The measurement uses the exclusive decay channel B+ to J/psi K+, with J/psi mesons that decay to a pair of muons. The results show a reasonable agreement with theoretical calculations within the uncertainties.

description: Wahrscheinlich wird jeder Lehrer, der ein zentrales Thema wie Äquivalenzumformungen bei linearen Gleichungen behandelt, das Kapitel mit einem Test abschließen, der korrigiert, evtl. benotet und zurückgegeben wird. Bei der Besprechung der Testergebnisse mit den Schülern wird er die Aufgaben nach ihrem Anspruchsniveau gewichten, über den einen oder anderen Lösungsweg diskutieren, auf die häufigsten Fehler eingehen und sich passende Übungen überlegen. Ist der Test gut ausgefallen, sind Schüler und Lehrer zufrieden, für weitere Analysen aber bleibt in der Regel keine Zeit. Anhand von Materialien aus dem Archiv der ehemaligen Zentralstelle für Computer im Unterricht, ergänzt durch aktuelle Erhebungen sollen mit nicht zu aufwendigen Werkzeugen differenzierte Auswertungen eines Tests zu linearen Gleichungen versucht werden.
