Svenska översättningar av Brief Electricity and Magnetism Assessment (BEMA) och Conceptual Survey of Electricity and Magnetism (CSEM) har gjorts. BEMA och CSEM är forskningsbaserade flervalsprov som testar konceptuell förståelse inom elektromagnetism och kan vara utgångspunkt för en fysikundervisning med fokus på konceptuell förståelse på flera nivåer av utbildning. Originalfigurer har använts med en figur modifierad för att förtydliga positionen av en partikel (CSEM uppgift 15). För att motivera översättningarna har det argumenterats för en konceptuell fysikundervisning i kontrast mot en traditionell. Detta gjordes utifrån Skolverket, en rapport ifrån Skolinspektionen och ett flertal publikationer inom Physics Education Research (PER). Speciellt har det argumenterats för en konceptuell fysikundervisning inom elektromagnetism genom att en översikt av de konceptuella utmaningar som området ofta innebär för elever har presenterats. Vid tillfällen har det också givits riktlinjer för hur utbildare kan gå tillväga för att bemöta dessa utmaningar. Utifrån aspekterna svårighetsindex, träffsäkerhet och reliabilitet inom Classic test Theory (CTT) kan BEMA och CSEM anses vara likvärdiga. Den som vill använda BEMA eller CSEM bör därför främst, och kanske också enbart, kolla på vilket av testerna som innehållsmässigt bäst stämmer överens med den aktuella kursen. BEMA och CSEM är innehållsmässigt väldigt lika och har flera uppgifter gemensamma, samtidigt som det finns skillnader, till exempel testar BEMA förståelse för elektriska kretsar medan CSEM inte gör det. Antar vi att BEMA och CSEM är likvärdiga utvärderingsverktyg, och eftersom båda består av ungefär lika många (31 och 32) uppgifter samt enbart flervalsfrågor, kan de användas som för- och eftertest inom samma grupp eller parallellt om två grupper ska testas inom samma kurs. Uppgifter om elektriska kretsar kan då behöva uteslutas ifrån BEMA för en bättre innehållsmässig överensstämmelse mellan proven. CTT är beroende av testgrupp, och eftersom de CTT resultaten som presenteras är baserade på amerikanska collegestudenter kan det vara lämpligt att som utbildare undersöka om BEMA och CSEM även är likvärdiga inom den kontext som de ska användas. / Swedish translations of Brief Electricity and Magnetism Assessment (BEMA) and Conceptual Survey of Electricity and Magnetism (CSEM) have been made. BEMA and CSEM are research-based multiple choice tests on conceptual understanding of electromagnetic concepts. They can be used as a starting point for physics teaching with emphasis on conceptual understanding at several levels of education. Figures are from the original tests with one figure modified in order to clarify the position of a particle (CSEM question 15). In order to motivate the translations I make a case for a conceptual approach to physics teaching in contrast to a traditional. This was based on the Swedish National Agency for Education, a publication from the Swedish School Inspectorate and several publications within Physics Education Research (PER). I Specifically make a case for a conceptual approach to physics teaching within electricity and magnetism with an overview of common student difficulties. Occasionally guidelines for how educators can deal with these challenges are given. Based on the aspects difficulty, discrimination and reliability within Classic test Theory (CTT) BEMA and CSEM can be considered equivalent. Those who wish to use BEMA or CSEM should therefore mainly, and perhaps only, decide which test to use based on which test that best matches the course in terms of covered content. Contentwise BEMA and CSEM are very similar and have many questions in common. However, there are differences between them. For example, BEMA tests understanding regarding electric circuits while CSEM does not. If we assume that BEMA and CSEM are equal in quality and combine this with the fact that they are made out of almost the same amount of questions (31 and 32) that are only multiple choice, BEMA and CSEM can potentially be used as pre- and post-tests within the same group or in paralell if two groups are to be tested within the same course. In order to match the two tests in terms of content, electric circuit questions could be omitted from BEMA. CTT results depend on the tested group, and since the CTT results that are presented is based on American college students, further investigation is needed to ensure that they are equivalent also in the Swedish context.

L'étude pétrographique et géochimique des granites Taourirts est entreprise. Le chapitre 1 fait la synthese des études sur la géologie du Hoggar ( 1981) Le chapitre 2 aborde la répartition et l'étude des intrusions de granite de type Taourirt et les minralisations associées Le chapitre 3 traite de la pétrographie de ces intrusions Le chapitre 4 aborde l'aspect géochimie.

In this study, we tested the performance of ChatGPT-4 on the concept inventory Brief Electricity and Magnetism Assessment (BEMA) to understand its potential as an educational tool in physics, especially in tasks requiring visual interpretation. Our results indicate that ChatGPT-4 performs similarly to undergraduate students in introductory electromagnetism courses, with an average score close to that of the students. However, ChatGPT-4 displayed significant differences compared to students, particularly in tasks involving complex visual elements such as electrical circuits and magnetic field diagrams. While ChatGPT-4 was proficient in proposing correct physical reasoning, it struggled with accurately interpreting visual information. These findings suggest that while ChatGPT-4 can be a useful supplementary tool for students, it should not be relied upon as a primary tutor for subjects heavily dependent on visual interpretation. Instead, it could be more effective as a peer, where its outputs are critically evaluated by students. Further research should focus on improving ChatGPT’s visual processing capabilities and exploring its role in diverse educational contexts.

The assignment of the diploma thesis was the elaboration of an architectural study of a new synagogue in the Frýdek-Místek. The solved area includes the original lands of the Jewish community, on which stood a synagogue, a Jewish school and a rabbinate. The synagogue was burned down in 1939 and currently only the rebuilt Jewish school building is located in the area. The main idea of the design is to build a memorial on the site of the original synagogue and a new synagogue with an adjoining community centre. The main goal is to support the development of the Jewish community in the city and to remind citizens and visitors of the history, because of which the Jewish community in Frýdek-Místek disappeared. In contrast to the monument, the entire building is set in the terrain so that the terrain passes freely in a public space with the main entrance to the community centre and a kosher restaurant. The building opens up to the south side of the slope and offers a view of the historic city centre of Frýdek. The area is connected by a footbridge to the park under the castle. Part of the community centre is a space for a ritual bath - Mikveh, the administration of the Jewish community and a multifunctional hall, which can be opened to the area in front of the residential staircase. The area is separated from Revoluční Street by a retaining wall and thus form an attractive place to spend time near the historic centre.

Magister Scientiae - MSc (Physics) / An increasing energy demand and growing environmental concerns regarding the use of fossil fuels in South Africa has led to the challenge to explore cheap, alternative sources of energy. The generation of electricity from Photovoltaic (PV) devices such as solar cells is currently seen as a viable alternative source of clean energy. As such, crystalline, amorphous and nanocrystalline silicon thin films are expected to play increasingly important roles as economically viable materials for PV development. Despite the growing interest shown in these materials, challenges such as the partial understanding of standardized measurement protocols, and the relationship between the structure and optoelectronic properties still need to be overcome.
