Abstract Despite the difficult circumstances due to the COVID-19 pandemics, physics students can tackle interesting questions that are part of physics competitions as the German Physicists' Tournament (GPT) 2020. Due to the COVID-19 pandemics in 2020, many competitions such as the GPT are held online. Furthermore, the usual options of equipment offered by the supervising university institutions could not be used by the students. The problems of the GPT 2020 therefore had to be chosen in such a way that they could be examined at home using simple means. One of these supposedly simple but profound experiments - the Cartesian diver - is described in this article. The Physics of the Cartesian diver has been discussed before [2, 3, 22], as well as various modications [21]. We present a new way of investigating Cartesian divers quantitatively by using 3D printing and common household materials. The paper is addressed to undergraduate students and educators teaching physics at university.

Summary This paper examines Ann Fisher’s (1719–1778) most important and influential work, A New Grammar (1745?). In this grammar, the author did not follow the trend of making English grammar fit the Latin pattern, a common practice still in the eighteenth century. Instead, she wrote an English grammar based on the nature and observation of her mother tongue. Besides, she scattered throughout her grammar a wide set of teaching devices, the ‘examples of bad English’ being her most important contribution. Her innovations and her new approach to the description of English grammar were indeed welcomed by contemporary readers, since her grammar saw almost forty editions and reprints, it influenced other grammarians, for instance Thomas Spence (1750–1814), and it reached other markets, such as London. In order to understand more clearly the value of this grammar and of its author, this grammar has to be seen in the context of her life. For this reason, we will also discuss some details of her unconventional lifestyle: unconventional in the sense that she led her life in the public sphere, not happy with the prevailing idea that women should be educated for a life at home.

In this case study, undergraduate students presented physics concepts to patrons at a planetarium. This created an early opportunity for these pre-professionals to practice the process skill of oral communication to a lay audience. The case study resulted from working with students participating in a grant called the da Vinci project. It reports on a situated experience pre-engineering and calculus-based physics students had working with their professor to create a brochure and present a physics concept to patrons visiting a public planetarium. Working closely with their professor, students were able to use this required professional skill in a real world (situated) context. This opportunity helped bridge the gap between these pre-professionals’ experiences in training and in their careers in STEM fields. Thirty students attending a two-year college in the Southwestern US self-selected to participate in the project. Each student participant built a kit-based model of a machine, designed an informational flyer aligned to state K-12 physical science standards, and presented informally to the public visiting a planetarium. Data were collected from the students via written reflections before and after the presentation and from email correspondence with their professor. Qualitative analyses of these reflections assessed the students’ progress toward a finished presentation. Results suggest that obstacles to public speaking fluency come from the fear of making mistakes or giving out misinformation. Opportunities to engage in informal public speaking helped overcome these obstacles. Students demonstrated increased confidence in their ability to share their knowledge with the public after undergoing guided informal speaking practice. The opportunity for students to practice public speaking during their undergraduate training can increase confidence and better prepare them for a career.

This paper presents an experience report concerning the use of a platformcalled “Storium” in the subject of “Interactive Fiction” for undergraduatestudents, from a Digital Design Course. The objective was to use the learningtheories of constructivism and multimedia learning to create an instructionalplan devised to teach the students how to create complex interactive narrativesand stories from a practical perspective. During the course, the students learnedthe subject’s theoretical concepts and applied them directly, creating their owninteractive fiction. The results from this research proposes a new approach, usingdigital tools whose resources provides an environment for the creation ofinteractive narratives. These narratives can be used to aid future designs ofinstructional plans for complex writing concepts.

Large Groups

This chapter describes the experiences of the authors as lecturers in the development of a new approach to teaching large groups of first-year undergraduate students in psychology. Drawing on constructivist and instructivist approaches, our mixed model incorporates both face-to-face and online components, capitalising on the relative strengths of each. Online material, with a strong emphasis on active engagement, is used to introduce students to the content before undertaking a more detailed reading of the key theoretical and research issues in the textbook. With this introduction to the material, lectures function as a “Review and Discussion” session rather than a didactic monologue. Outcomes of the mixed method suggest no adverse effects on student performance, and staff and students evaluate the new approach favourably. The mixed model approach to teaching large groups is one that might be adapted for a range of disciplines and content.

This chapter talks about how historians have re-evaluated the place of the Jews in the Polish–Lithuanian Commonwealth as a whole and in their individual communities over the last generation. It gives details on how historians have come to regard Jews as not only “in” Poland but “of” Poland and how they are inextricably linked to the social, economic, and cultural processes of the country. G.D. Hundert, a major proponent of the new approach, insisted that to Polish Jews, “Poland was as much theirs as their neighbors.” However, the chapter explains that it does not mean the Jews were perfectly integrated in an American ideal-type pluralist society. It analyzes how Hundert was quick to point out that while Jews felt at home in their communities, there was no question that animus and tension were the governing qualities in relations between Jews and Christians.

And Mathematics

The quantum harmonic oscillator is a fundamental piece of physics. In this paper, we present a self-contained full-fledged analytical solution to the quantum harmonic oscillator. To this end, we use an eight-step procedure that only uses standard mathematical tools available in natural science, technology, engineering and mathematics disciplines. This solution is accessible not only for physics students but also for undergraduate engineering and chemistry students. We provide interactive web-based graphs for the reader to observe the shape of the wave functions for an electron and a proton when both are subject to the same potential. Each of the eight steps in our solution procedure is treated as a separate problem in order to allow the reader to quickly consult any step without the need to review the entire article.

Testing Approach

This paper addresses a structure design competition based on topology optimization and 3D Printing, and proposes an experimental approach to efficiently and quickly measure the mechanical performance of the structures designed using topology optimization. Since the topology optimized structure designs are prone to be geometrically complex, it is extremely inconvenient to fabricate these designs with traditional machining. In this study, we not only fabricated the topology optimized structure designs using one kind of 3D Printing technology known as stereolithography (SLA), but also tested the mechanical performance of the produced prototype parts. The finite element method is used to analyze the structure responses, and the consistent results of the numerical simulations and structure experiments prove the validity of this new structure testing approach. This new approach will not only provide a rapid access to topology optimized structure designs verifying, but also cut the turnaround time of structure design significantly.
