Although researchers have extensively studied student conceptions of radioactivity, the conceptions held by preservice teachers on this subject are largely absent from the literature. We conducted a qualitative content analysis of problem-centered interviews with preservice teachers (N=13) to establish which conceptions are held by preservice…

A comprehensive teaching experiment plan tailored forthird-yearundergraduates has been developed. Initially, instructors synthesize(E)-2-(4-((4-(2-hydroxyethoxy)-3-methylphenyl)­diazenyl)­phenoxy)-ethan-1-ol­(M-Azo-2)monomer as part of the preclass preparation. Subsequently, studentsperform an acylation reaction experiment to prepare an…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

The European Union Radiation, Education, Staffing & Training (EU-REST) study aimed to collect and analyse workforce availability, education, and training needs to ensure quality and safety aspects of medical applications involving ionising radiation and to develop staffing and education/training guidelines as well as conclusions and…

The teaching of the phenomenon of radioactivity is considered a key ingredient in the path towards developing critical thinking skills in many secondary science education curricula. Despite being one of the basic concepts in general physics courses, the scientific teaching literature of the last 40 years reports a great deal of misconceptions and…

Background: Late side effects of head and neck cancer treatment commonly affect swallowing function. Late radiation-associated dysphagia (late-RAD) often presents years post-treatment when patients have been discharged from their multidisciplinary team. Timely symptom management may provide important physical and emotional support, potentially…

The objective of this study was to measure the contribution of the left frontopolar cortex (FPC) to analogical reasoning. Our measure of analogical reasoning derives from performance on the radiation problem, a creative problem-solving task first used in Gestalt psychology (Duncker, 1945). Success on this task is as low as 10 % without the…

This study aims to determine pre-service teachers' conceptual understanding of black-body radiation. Designed as a qualitative study, it employed a case study design, which is one of the descriptive research methods. The study group consists of 18 pre-service physics teachers enrolled as seniors. An opinion form and a concept map were used as data…

Wi-Fi radiation is a type of radio frequency electromagnetic radiation (RF-EMR) that refers to the transfer of energy by radio waves. Nowadays, exposure to RF radiation is widespread including wireless internet connection (Wi-Fi) routers and cell phones. The proliferation of devices emitting RF radiation has entailed some public and…

This paper presents the case for how students can be helped to increase their scientific vocation by experimental work and the introduction of particle physics into pre-university studies. These two ideas are the two main lines of work of the ADMIRA initiative, which has been created by individuals belonging to different and complementary…

This paper reports the development and application of a low-cost multifunctional webcam spectrophotometer for the conduct of molecular absorption and fluorometric measurements. The equipment, which costs approximately US$20 to be fabricated, consists of a webcam, a diffraction grating, and a slit, all positioned inside an MDF box. Spectral…

The various radiation types that make up the electromagnetic (EM) spectrum are ubiquitous and highly significant in modern society. Detection of visible light by the eye facilitates sight, radio waves and microwaves are used in communication technologies, x-rays are used in medical imaging, and gamma rays are frequently employed in medical…

Infrared (IR), or radiation, thermometers are widely used in temperature measurements in many different sectors from health, food, automotive, agriculture, iron and steel to chemistry due to their fast measurement capabilities, reasonable prices, wide measurement ranges and ease of use. IR thermometers work based on black body radiation. In this…

Radiochemistry faces a well-documented training and recruitment crisis. Older radiochemists are retiring, and fewer young people are studying radiochemistry. In turn, this is leading to a shortage in newly qualified radiochemists, as well as a loss of historical knowledge (as know-how is often not passed-on). Here, we analyzed the relevance of the…

Background: Japan has recently begun introducing educational programmes on cancer as part of health and physical education (HPE) classes in schools. In support of this work, the Japanese Society for Radiation Oncology has developed an educational video to enhance children's understanding of cancer and radiotherapy. Objectives: This study examined…
