Solid-state physics has important applications in the development of modern technologies. Although solid-state concepts, such as electric and thermal conductivity, are included in the curricula at ...all educational levels, even university students have many incorrect ideas about them. The incorrect ideas identified in previous studies are mainly related to macroscopic aspects of solid-state physics. With the aim of gaining a more comprehensive insight into students’ understanding of solid-state physics, we have developed a multiple-choice concept inventory on microscopic models of electric and thermal conductivity of solids (METCS). The inventory has been field-tested with a sample consisting of 233 first-year medical faculty and engineering students from the University of Rijeka (Croatia). METCS proved to have good psychometric features and it helped to uncover many incorrect ideas that have not been reported in the earlier physics education literature. The findings from this study could be a good starting point for the development of evidence-based, university-level tutorials on microscopic models of electric and thermal conductivity.
Introduction Nutritional deficiency among the older adult is a widespread concern, significantly affecting their health. The prevalence of malnutrition increases with age, concurrent health ...conditions, and the level of care provided. Hospital stays can affect as 90% of the older adult. Malnutrition can hinder efforts to improve health and regain function in individuals undergoing rehabilitation. This study aims to assess the frequency of malnutrition among geriatric rehabilitation patients. Materials and methods A retrospective quantitative analysis was conducted on 357 patients admitted to the geriatric unit at Lucerne Cantonal Hospital Wolhusen in Switzerland. The patients’ nutritional status was evaluated using the standardized Mini Nutritional Assessment Long Form questionnaire. Results The initial analysis indicated a considerable prevalence of malnutrition among the geriatric population: 31.1% were identified as malnourished (MNA < 17), while an additional 35.8% were at risk of malnutrition (MNA 17–23.5), totaling 66.9% of patients. The Kruskal-Wallis ANOVA test revealed a statistically significant difference in MNA scores among different age groups ( p = 0.035). Statistical analysis also suggested a slightly higher prevalence of malnutrition among female patients. The duration of rehabilitation varied from 20.07 ± 6.93 to 22.20 ± 7.50 days, with longer durations associated with lower MNA scores. A correlation analysis between MNA values and body mass index (BMI) showed a positive correlation coefficient ( r = 0.56), indicating that lower MNA scores were associated with lower BMI and vice versa. Conclusion Malnutrition is prevalent among individuals over 65 years old, highlighting the importance of regular and timely nutritional assessments for geriatric patients to mitigate the complications and enhance prognoses in both acute care and rehabilitation settings. Such assessments can also improve the efficacy of rehabilitation programs and potentially reduce the duration of rehabilitation, thus carrying significant economic implications.
Knowing the causes of the shortage of physics teachers in primary and secondary schools is necessary for the development of effective educational policies because the shortage of physics teachers is ...a global and persistent problem with negative consequences for the quality of education, but also for the survival of the physics profession as a whole. The aim of this study was to investigate, for the first time, the opinions of Croatian physics teachers on the causes of the deficit in their profession. For this purpose, we conducted a descriptive cross-sectional study using an online survey with Likert-type items and a constructed response item. A total of 390 respondents from all over Croatia participated in the survey, which is 29% of the total population of Croatian physics teachers in the 2022/2023 school year. According to their opinion, the causes of the shortage of Croatian physics teachers are related to the following: lack of incentives and support from the relevant institutions and bodies, the inadequacy of physics content in the curricula, the lack of motivation and negative attitude of students towards physics, impeded professional development, unequal opportunities, and challenges such as excessive workload. The results obtained provide a concrete basis for the development of an effective policy to solve the problem of the physics teacher shortage in Croatia and beyond by governments, universities, and schools.
AbstractEducation plays a key role in the development of human civilisation. Learning and teaching methods are still evolving and undergoing numerous changes as a result of scientific knowledge and ...revolutionary ideas of stakeholders in the education system, and the development of advanced technologies. We are all familiar with traditional ways of learning wherein educational process is conducted in such a way that the focus is primarily on content. Jan Amos Komensky, the alpha and omega of education science, laid out the class-subject-lesson traditional education system and designed, as early as the 17th century, the school as an institution capable of meeting the mass educational demands of the time. Because these traditional methods use repetition and memorisation of information as the principal means of acquiring knowledge, students are unable to develop their critical thinking, problem-solving and decision-making skills. In the 21st century, teaching should be focused on the effective cooperation between teachers and students who are actively participating in the teaching process, because such an approach ensures the training of innovative individuals who go on to become qualified professionals and responsible citizens, thus creating a more affluent and safer society in general. This paper provides an overview of the important characteristics of modern schools, as well as some modern teaching strategies.

Tehnološki napredak i razvoj računala omogućili su proizvodnju složenih uređaja koji koriste ionizirajuće zračenje za elektroničko snimanje ljudskog tijela, kao i obradu slikovnih prikaza u ...dijagnostičke i terapijske svrhe. Studentima Prijediplomskog stručnog studija Radiološka tehnologija je neophodno temeljito poznavanje fizike za učinkovitu i sigurnu uporabu novih tehnologija, ali i za razumijevanje principa njihovog rada. Iako spomenuti studij povezuje znanja iz područja informatike i statistike s medicinskim, tek uz razumijevanje fizikalnih zakonitosti o konceptima koji se spominju u okviru medicinske radiologije, studenti postaju kompletni stručnjaci educirani za samostalan rad ili rad u timu u području radiografije, nuklearno-medicinske te radiološke dijagnostike i terapije.
Istovremeno, poznavanje i konceptualno tumačenje zakona fizike nužni su za razumijevanje temeljnih bioloških procesa unutar ljudskog tijela, poput rada srca ili prijenosa živčanih impulsa. Stoga se u okviru kolegija Fizika stavlja naglasak na poznavanje strukture tvari i građe atoma, elektromagnetizma, ultrazvuka, elementarne nuklearne fizike, prirode ionizirajućeg zračenja te proizvodnje i primjene X zraka koje su temeljne za razumijevanje fizike medicinskog snimanja.
U radu su izdvojena neka područja koja su sastavni dio kolegija Fizika na Prijediplomskom stručnom studiju Radiološke tehnologije.
