TY - GEN A1 - Stanzel, Silke T1 - Analysis of student conceptual development using the Force Concept Inventory N2 - The Force Concept Inventory (FCI) is a widely established diagnostic tool for the conceptual understanding of Newtonian mechanics. It consists of 30 multiple-choice questions on kinematics and forces. Many of the distractors reflect widespread preconcepts or misconceptions. By analyzing the frequency of all answers rather than only the correct ones conclusions can be drawn on the conceptual development of students. Using the method of "item response curves" (Morris 2006), the relative frequency of all answers is plotted for each question as a function of the total score achieved in the test. By this, distractors that address common misconceptions can be identified. Furthermore, the conceptual development becomes visible. We have analyzed the results of the FCI over a period of nine years from almost 5000 first-year engineering students at the TH Rosenheim. We compare data taken at the very beginning of physics class with data taken at the end of the term as well as with data from universities in the USA. The consistency of the data is very high. The most frequently selected answers include misconceptions about Newton's third law and the assumption that every movement is based on a force in the direction of the movement. The analysis presented serves as a basis for improving teaching.

Instead of receiving lectures in SCALE1UP students work actively together in small groups, mostly at round tables and are guided by teaching staff. This concept is implemented at Rosenheim University of Applied Sciences, Germany, in several classes of physics and mathematics for engineering students. Classroom observations have been carried out in summer term 2023and winter term 2023/24 in order to investigate student learning in the SCALE-UP setting. The observations are based on ELCOT-3, the Engineering Learning Classroom Observation Tool (Sanders et al., 2018). An observation includes the overt student behavior in combination with the students’ output. The data have been analyzed with respect to the ICAP-framework (Chi&Wylie, 2014), where the different observed activities have been assigned to Interactive, Constructive, Active, and Passive mode. In this contribution we present examples on how students interact with the offered material, that means in which ICAP-modes students work with different learning activities in the SCALE-UP setting. Moreover, we show that in all observed courses students have been learning a substantial part of class time in interactive and constructive mode.

The vibration reduction index Kij can be determined from the direction-averaged junction velocity level difference and the structural reverberation time. Both quantities have to be measured according to EN ISO 10848. Alternatively, in prEN ISO 12354-1:2016 a first proposal to derive the vibration reduction index for T- or cross-junctions is mentioned. Nevertheless, for a reliable prediction of the sound transmission across junctions of Cross Laminated Timber (CLT) further research results and data are required. This paper documents frequency-dependent vibration reduction indices of L-, T- and cross-junctions measured by six international institutes. This documentation is part of the master’s thesis “Junctions of solid timber constructions – Construction details, acoustical parameters, sound insulation prediction” (in German: Stoßstellen im Massivholzbau – Konstruktionen, akustische Kenngrößen, Schallschutzprognose) at the Technical University Berlin in cooperation with the University of Applied Sciences Rosenheim.

Barriers such as limited usability, varying levels of digital literacy, and persistent age-related stereotypes are documented to hinder technology adoption among older adults. User-centered design approaches, such as the persona method, offer strategies to address these challenges. Objective: Personas were created to inform the development of technologies supporting ageing in place by enhancing stakeholders’ understanding of needs and technology experience among older adults. Methods: The personas were developed through an iterative process, with this paper detailing the last stage, which employed the a PATHY technique as conceptual framework for content analysis. Eleven focus group discussions were conducted in southern Germany, of which nine were included in the analysis. These involved older adults in need of support, with orthopedic and neurological conditions, and in informal caregiving roles. Results: Five hybrid personas were created to represent the target groups’ experiences related to ageing in place, each reflecting needs, problems, existing solutions, habits, sociodemographic characteristics, and dimensions of technology experience. Key factors influencing technology experience and uptake among the personas were identified, including the social context and availability of support, the perceived trade-off between safety and digital privacy, and the persistence of the digital divide. Conclusion: The findings underscore the necessity of adaptable, context-sensitive technology solutions, displayed by the personas’ needs, pains, routines and technology experiences. Thereby, the hybrid personas reinforce the importance of a more relational and context-aware approach in user-centered design.

This is usually done in a fluidized bed (Wurster coater) or a coating drum. Pneumatic conveying systems are usually already installed for conveying particulate media, for example between process steps or the filling. In pneumatic conveying, the fluidized state of the Wurster Coater is already present. The basic idea of the current project is to implement the coating step directly in the pneumatic conveying system. Experimental approach: The coating tests were carried out using a vacuum system. For this purpose, various coating chambers with different nozzle arrangements were printed using a rapid prototyper. The nozzles used were also printed in-house and adapted to the requirements. Particles with a diameter of 3 mm were used for the tests and sprayed with a common protective coating as well as blue dye. The particles were heated to 120°C in order to supply the necessary heat to evaporate the solvent. Images of the coated particles were taken and evaluated with ImageJ to analyze the coating result. The amount of coating delivered changes the coating layer linearly as expected. The tests showed that it is possible to coat particles during pneumatic conveying. A comparison with coating in a Wurster coater showed that the amount of overspray is higher than in a Wurster coater, leading a lower efficiency in the coating step in pneumatic conveying though.

A quasi-experimental design with three experimental groups and a control group was used. The findings reveal significant differences in AI literacy and usage patterns among students. The constructive-aligned TS 3 ‘SciAI’ demonstrates the most pronounced effects, particularly in knowledge and understanding AI and ethical considerations. From this, optimal strategies for integration of AI into educational practices can be de-rived.

This relationship is of particular importance for redox materials such as \(Ca_{1-x} Sr_x MnO_{3-\delta}\), where reversible oxygen ions exchange and oxidation state shifts are key to their functionality. In the first study, scanning electron microscope (SEM) was used to examine how varying Sr content affects the morphology and microstructure of \(Ca_{1-x} Sr_x MnO_{3-\delta}\) powder compositions. The results indicate that increasing Sr content leads to smaller particle sizes and improved particle size homogeneity. Granules with Sr concentrations ranging from 0 % to 40 % exhibit notable changes in morphology. However, the microporosity and d50 vary slightly across the samples in a non-monotonic manner, with no clear trend emerging with respect to Sr concentration. The second study investigates how macrostructural forms, such as foams and pellets, impact oxidation kinetics in \(Ca_{0.8} Sr_{0.2} MnO_{3-\delta}\). Parameters including particle size distribution of the raw material, overall microporosity, and structural characteristics of these macrostructures were analyzed for their effect on oxidation rates. Findings reveal that macrostructural configuration, alongside microstructural features like microporosity, significantly impacts oxidation kinetics. These studies collectively underscore the critical relationship between dopant concentration, microstructural characteristics, and structural morphology in determining the oxidative behavior of \(Ca_{1-x} Sr_x MnO_{3-\delta}\), providing key insights into optimizing material performance in redox environments.

Through nine expert interviews with physicians from diverse medical backgrounds, the study aims to understand concerns and anticipated benefits of AI in the doctor–patient relationship. To demonstrate AI’s applications, digital anamnesis surveys were conducted with two actual patients, and the resulting data were interpreted by AI and reviewed by physicians. Findings indicate that physicians view AI as potentially beneficial, expecting that AI can facilitate improvements in care quality, efficiency, and time savings. Despite initial concerns about AI’s ability to address individual patient needs and its impact on the doctor–patient relationship, there is significant interest in integrating AI tools into daily practice. Key issues include patient constitution, the effort-to-benefit ratio, and potential risks to patient trust. The study identifies six areas for further research: Economic impact and cost-benefit analysis, patient acceptance and trust, stress reduction and job satisfaction, effects on doctor–patient relationships, development of verification mechanisms, and ethical and legal considerations. These findings underscore the complexities of AI integration in health care, emphasizing the need to address concerns about patient individuality, data privacy, and interpersonal relationships while harnessing AI’s potential.

T2 - Proceedings of the 12th International Conference on Physics Teaching in Engineering Education PTEE 2024 N2 - A "hybrid" team-based physics course was developed and rolled out at the Albstadt-Sigmaringen University, Germany, with the intention to provide more flexibility in space and time for the students. Data on the correlation between type of participation and learning success showed, that participation in person together with the performance in other STEM related courses are the main predictors for learning success. Interestingly, it had no influence on the learning success of the non-participating students whether they participated remotely or not at all. Thus, the biggest challenge for the lecture of the future, which offers more flexibility in space and time, is the "activation" of students who participate remotely.

The new model also offers some strong support for those students that are at the greatest risk to underperform or drop out their studies. The flexibility includes a possibility for an asynchronous online implementation in every physics and mathematics course. The stronger support means some extra workshop lessons for those who are in danger of dropping out. These workshop lessons concentrate on the very basics of the subject matter.

The study explores various issues encountered by educators when students utilize AI to solve physics problems, highlighting potential pitfalls and opportunities. Through testing AI chatbots' capabilities in physics learning, the paper evaluates their effectiveness in providing accurate and insightful responses. Results indicate that while AI, especially ChatGPT 4, shows promise in aiding students' understanding of physics concepts, there are limitations and challenges to consider, such as over-reliance on technology and the potential for AI to produce misleading solutions. The implications and discussions underscore the need for a balanced approach in integrating AI into education, emphasizing authentic understanding over merely obtaining correct answers.

The transformation of a traditional physics laboratory into a versatile group work and multipurpose space known as the “STEM-Center,” at Tampere University of Applied Sciences is presented. The transformation was inspired by active pedagogical methods such as "Peer Instruction," "PDEODE," and the "SCALE-UP" method and its associated spaces. After the transformation, the space remains suitable for physics laboratory work. Across all courses, it encourages students to be active participants rather than passive listeners, which in turn improves learning outcomes. Most students express high satisfaction with the pedagogical methods and the learning environment as well as a preference for these engaging and activating methods over traditional lecture-based teaching, highlighting an enhanced learning experience and a stronger sense of ownership over their learning.

In this context the lab is continuously used and developed by university students. The lab itself focusses on conducting key experiments in quantum mechanics and the visualization of quantum mechanical effects. By exploiting the contradiction between classical expectation and experimental observation, cognitive dissonances are stimulated and later resolved, which leads to an increased learning outcome. Conducting existing experiments is, however, in some cases hindered by a complicated alignment, which does not aid the quantum mechanical understanding. The desired learning outcome can thus not be achieved in all cases. In order to address these challenges and to allow for a future remote use of the laboratory, three pilot experiments were transformed into cross reality labs. This allows to decouple the students’ learning experience from the location of the lab. This paper provides an overview over the digitized experiments and gives an outlook on the future of the learning teaching laboratory.

For the winter term 23/24 the lecture format was shifted towards a more interactive format, aiming at specific physics problems to be solved as part of the lecture. In order to free up the necessary time in the lecture itself , the conveyance of knowledge was shifted to the students’ preparation for the individual lectures, by providing texts and videos, which were aided by a short quiz. The lectures as well as the preparation were accessed over the entire semester. This paper provides an overview over the results obtained from the assessments and the final exams, as well as the lessons learned.

There is evidence that instructional materials that take into account such difficulties and prompt students to critically assess their own understanding can improve student learning. In this paper Tutorials in Introductory Physics are introduced, a set of materials intended to supplement the lecture, textbook, and laboratory of standard introductory physics courses for students in physics, engineering, and other fields. The Tutorials in Introductory Physics were originally developed by Lillian McDermott and the Physics Education Group at the University of Washington. They have been translated into other languages, including Spanish, Greek and German. In addition, they have served (and continue to serve) as a model for the development of instructional materials for other STEM subjects, such as electric circuits and engineering mechanics. We discuss various aspects of incorporating the Tutorials into a typical course and possible issues associated with their implementation.

To understand how scientific progress happens, it is necessary to understand the fundamental process by which science generates new knowledge. Teaching the process from observation, hypothesis, prediction, experiment/thought experiment, testing and possibly revising the hypothesis to a theory poses several challenges for the teacher. We will show how we let our students carry out this process themselves in a teaching unit of 1.5 hours.

Nevertheless, experienced instructors often do not switch to those methods in their teaching, and first-time lecturers start with traditional instead of activating methods. This article is aimed at (future) educators who are thinking about implementing such methods, as well as experienced ones and educational support staff who wish to provide support for their colleagues. This report is based on personal experience, (free-response) evaluations, standardized tests, and literature. It shows, which factors supported the introduction of and transformation to activating teaching methods, which made it difficult, and which would have been helpful. It is demonstrated why a changeover is worthwhile for physics educators despite possible risks and setbacks.

Therefore, sound insulation requirements have to be met and the prediction of sound insulation for this construction type is necessary. With the exception of low frequencies, Statistical Energy Analysis (SEA) is used in building acoustics for this purpose, which requires material properties as input data. The material characterisation of Cross Laminated Timber is a challenge. On the one hand, the composite material consists of several layers of boards; on the other hand, wood itself is inhomogeneous, anisotropic and has a low shear modulus. Differences in the manufacturing process such as the use of glue and grooves also have an impact on the overall rigidity of the plate. A characterisation based on thin plate theory is insufficient for the frequency range of building acoustics. One possibility to address this challenge is the experimental determination of frequency dependent phase velocities of bending waves in a plate that account for the above-mentioned effects. From the wave velocities the modal density used in SEA can be calculated very efficiently. This contribution focus on the time-of-flight method and phase difference method to determine phase velocities. In a case study, the direction-dependent global stiffness parameters were determined using first shear deformation theory. The measurement conditions and evaluation procedures are discussed.

A survey was conducted in GVTs in 2020 and 2021, when people's lives were primarily dominated by the pandemic. A transcription software was used to support the collaboration. A total of 530 survey responses were analyzed using a structured approach- qualitative content analysis. The data was structured using the SWOT framework that aimed at comprehensively answering the research question "To what extent is the use of Al-supported speech technology in GVTs useful?". Al-generated transcripts are helping to overcome language and time zone barriers in GVT. Yet, they also cause misunderstandings and impact openness of communication.

The relevant literature refers to an "organizational view" or "organizational mining" in process mining. In essence, process mining is about creating a time-logical chain of related tasks from automatically logged user activities on a computer. In this way, real processes can be mapped and analyzed as models. As a "by-product", task-related social networks are created between the process participants through the predecessor/successor relationships in the workflow. However, it should be noted and criticized that process mining research neglects the potential of social network analysis. The extensive findings of classical network research are not taken up further. An organizational and social scientific deepening of the data-driven preliminary work is missing in this discipline. Process mining, which tends to be mathematical and technical, has not yet developed the ambition to ally itself with empirical organizational and social research. This working paper tries to counteract this. It presents a first, social science-based approach to theoretically grounding process networks.

For applications as autonomous driving a high reliability has to be guaranteed. In this article we discuss how to combine probability distributions for failure. Discrete and continuous changes of the probability distribution in time are both considered. It turns out that the temporal order of the distributions, corresponding to the succession of stresses in applications, is essential. The latter observation restricts the general applicability of the widely used temperature collectives where only the total time of a temperature stress is considered neglecting the order of the stresses. An application of our results are thermal overstress tests on electric components. We may explain yet not well understood measurements for automotive electric cables.

Especially high prices of new drugs are perceived to be driver of growth which might threaten the sustainability of financing drugs. Objective The study aims to analyse a) whether German health policies can achieve sustainable growth of pharmaceutical expenditure, and b) which therapeutic groups fasten and slow pharmaceutical growth based on price and/or volume effects. Methods Annual growth rates of pharmaceutical expenditure in the German social health insurance (SHI) between 2006 and 2018 are compared with indicators reflecting the ability to pay. Annual growth rate in therapeutic subgroups are analysed with respects to volume and price developments. Results Without policies to control pharmaceutical spending, annual growth rates are significantly higher than the growths of indicators of ability to pay. After accounting for the savings from health policy measures, net pharmaceutical expenditure does not grow significantly faster than ability to pay. Policies mainly targeting generic drugs achieve threefold savings compared with policies targeting at patent-protected drugs, although the latter account for more than halve of the expenditure. A limited number of therapeutic subgroups with new drugs grow significantly faster than average expenditure, but this growths is counterbalanced by subgroups which in the end of their innovation cycle and a huge proportion of generic drugs. Conclusion The growths of net drug expenditure in the German SHI does not threaten the sustainability of financing health expenditure based on comprehensive policy measures and innovation cycle effects. Generics do contribute savings to a larger extent. Key points for decision makers: • Germany efficiently uses a comprehensive set of health policies to control drug expenditure in the social health insurance with limited impact on reimbursement. • Net drug expenditure grow on annual rates which correlate to ability to pay and thus do not threaten sustainability of health care financing. • Natural progress of innovation cycles together with targeted policies on patent-protected as well as generic drugs counterbalance exaggerated growth in areas with a high degree of innovation. • Policies targeted mainly on generic drugs yield threefold savings compared with policies targeting on patent-protected drugs. This imbalance should be considered in potential refinements of drug policies.

This is particularly true for credit institutions. The core banking systems used for internal processes are therefore subject to increasing digital change. In many banks, outdated IT systems are still in use, which often lack the basic functionalities that are essential for innovations. In order to achieve a sufficient functionality of the information technology in the company, core banking systems are implemented, which achieve the mapping of almost all bank-specific processes. In addition, so-called software robots are used to automate standard processes with increasing frequency. Due to the lack of standard products in previous years, there is an abundance of in-house developments. While self-developed systems dominate in the European as well as North and South American markets, earlier in-house developments in the German-speaking countries have mainly been replaced by standardized core banking systems. The introduction of standard ERP systems poses a major challenge for financial institutions. Not only does the implementation effort in terms of financial resources and working time play an important role, but also the ongoing expenses for maintenance and further development. These investments not only secure and promote the ability to innovate in the age of digitization, but also create an asset in the company. The evaluation for the accounting representation is an increasing challenge due to the steadily increasing complexity of information processing technologies. Questions arise regarding the access assessment, the follow-up assessment and the handling of previous systems. In the following, accounting according to the international accounting standards for the implementation of the ERP system SAP S/4HANA in credit institutions is shown. The procedure and the results are not limited to banks, but can be applied analogously to many industries.

In order to be able to carry out a comprehensive energy assessment of the system and building, it is necessary to be able to classify user influence during the evaluation. This thesis investigates how the presence of people in a room can be determined cost-effectively and with little additional effort. The aim is to determine which sensors of a room control system provide sufficiently reliable data. The presence of 1-2 persons was examined on a test facility of the Technical University Rosenheim. The air-, mean radiation- and surface-temperatures, the air humidity as well as the CO2 and VOC concentrations were measured. For the analysis, a method of supervised machine and statistical learning, random forest, is used. The smallest model error detected in predicting the presence of 1 or 2 persons from CO2 sensor data is 1.43%. The error rates are low for all tested models if time-dynamic effects are used as predictors and the data is processed in a so-called time period form. Additionally, the ways in which this data should ideally be made available for future measurements and processed to facilitate analysis with machine and statistical learning techniques have been investigated. A further goal is to apply the models developed on measurement series in laboratory environments to real rooms and to assess the transferability of these models.

There is substantial evidence that students have difficulty applying and prioritizing the two basic principles of mass conservation (i.e., the continuity equation) and energy conservation (i.e., Bernoulli’s equation). When distracted by questions which involve gravity students based their answers on ill-supported assumptions about local pressures. The predominant arguments use a simplified Bernoulli equation, descriptive arguments or analogies to single-particle motion. Based on these results, an instructional intervention is developed that seems to address the observed difficulties.

T2 - Proceedings of Euronoise 2015 N2 - Extended Abstract: The number of multi-storey buildings in timber construction increases continuously. Compared to concrete and brick constructions the planning process of sound insulation of a wooden building causes much higher effort. Reasons are missing planning data and planning tools for sound insulation. Suitable, computer-based tools, which enable a simulation already in an early planning phase of a building, could help to reduce the planning effort significantly. One possibility to calculate the in-situ airborne and impact sound insulation is to combine the Finite Element Method (FEM) and the Statistical Energy Analysis (SEA) in a coupled model, which consider the direct transmission path of the building elements and the flanking transmission paths. The SEA-based calculation of the sound insulation according to EN 12354 requires the vibration reduction indices of the transfer paths at a junction of structural elements. This paper shows actual measurement results of the Operational Vibration Analysis and the vibration reduction indices of coupled Cross Laminated Timber elements. In the process the elastic layers, the pressure and the fasteners were diversified. In addition the modelling of the junction by using a commercial SEA tool will be presented and the comparison of the calculated with the measured results. From this comparison conclusion about the valid frequency domain for the Statistical Energy Analysis will be presented. The results are based on the current status of the research project “Vibroakustik im Planungsprozess für Holzbauten” funded by the German Research Foundation (DFG) and German Federation of Industrial Research Associations (AIF).

T1 - Vibration reduction indices of CLT junctions T2 - Proceedings of ICSV24 N2 - The multi-disciplinary research project “Vibroacoustic analysis in the planning process of timber constructions“ carried out in cooperation between the University of Applied Sciences Rosenheim, the ift Rosenheim and the Technical University Munich is a comprehensive study of direct as well as flanking structure-borne and airborne sound insulation of Cross Laminated Timber (CLT) elements and their junctions. The aim is to optimize and simplify the acoustical planning process of wooden multi-storey buildings and thereby to contribute to the increase growth of timber construction industry in Europe. For a prediction of the acoustical performance of solid wood constructions, the vibration reduction index Kij is needed. The vibration reduction index can be determined i.a. of the direction-averaged junction velocity level difference and the structural reverberation time. Both quantities need to be measured according to EN ISO 10848. Alternatively, vibration reduction indices for a T- or cross-junction can be derived following the procedures described in prEN ISO 12354-1:2016. However, further knowledge and data of the sound transmission across junctions of CLT is inevitable for a reliable prediction. In this paper a collection of frequency dependent vibration reduction indices for CLT structures will be presented and compared, involving L-, T- and cross-junctions measured by six international laboratories.

The energy ratios of various subsystems are the main quantities to predict sound transmission. The method has proven to work sufficiently accurate for masonry and concrete buildings, where the building components like walls, floors etc. can be regarded as rather homogeneous structures. To adapt this method for solid timber constructions it is necessary to prove that basic SEA requirements are fullfilled by orthotropic materials and heterogeneous structures that occur in these building types. In a case study, an isolated T-junction formed by Cross Laminated Timber(CLT) elements is experimentally investigated. The buildings elements are subdivided in segments with typical screwed connections. In the experiments the diffusivity of the vibration field is investigated, using point excitation with a shaker at several positions and many, randomly chosen response positions. MONTE-CARLO simulations are conducted for random but fix-sized subsets of the measured response positions to find the necessary number of response positions for an accurate determination of the vibrational energy. As a result the distribution of the mean velocity levels can be approximated. In a second approach a multiple linear regression model based on the least absolute shrinkage and selection operator(LASSO)is applied, because for lower frequency bands multicollinearity is expected. In the context of linear regression modelling, data-driven methods are used to select optimal subsets of response positions, to get an estimating equation.

The benefit assessment is in relation to an “appropriate comparator therapy” (ACT) defined by the Federal Joint Committee (FJC). Based on the benefit assessment, a reimbursement price is negotiated. In order to proof added benefit, it is essential to provide evidence on patient-relevant outcomes from direct head-to-head comparisons with the ACT. Indirect treatment comparisons and evidence based on surrogate parameters are usually not sufficient. FJC often splits the indication into different subpopulations. Objective: The objective was to analyse whether factors beyond the clinical evidence have influence on the benefit assessment of the FJC. Methods: All benefit assessments between 2011 and 2015 were included in the analysis. The benefit for each drug was calculated by weighting the evidence grade, strength of evidence and size of subpopulations. Drugs were then clustered in high, low or no benefit. Univariate logistic regression was used to identify variables with potential influence (p<0.25). Those variables were included in a multivariate logistic regression model and variables with p>0.1 were excluded in a stepwise approach. Results: The final multivariate logistic regression identified that following variables increase the chance of getting a higher benefit: pharmacologically innovative drug, drugs in disease areas with high unmet medical need, drugs in oncology or infectious diseases, and drugs for which the FJC can split the assessment into subpopulations. Conclusions: The analysis identified variables beyond clinical evidence that influence the benefit assessment by the FJC and provided a better understanding of decision making by the FJC.
