Identifying students' misconceptions and learning difficulties and finding effective ways of addressing them has been one of the major concerns in chemistry education. However, the chemistry education community has paid little attention to determining discipline-specific aspects of chemistry that can lead to learning difficulties and misconceptions. In this article, it is argued that emergence plays a critical role in the epistemology and the ontology of chemistry and hence it should be taken into account for understanding learning difficulties and finding ways of addressing them in chemistry. It is particularly argued that one of the fundamental sources of learning difficulties and chemical misconceptions is learners' failure to understand the emergent nature of chemical entities, their properties, and interactions. In this article, an interpretive analysis framework is suggested for identifying specific learning demands and the sources of learners' misconceptions about the emergent chemical properties and phenomena. Findings from previous research on learners' misconceptions regarding emergent chemical properties are reanalyzed and interpreted through this framework. Inadequacies of typical teaching practices and their consequences are discussed from an emergentist perspective. Finally, implications of the emergentist perspective for more meaningful chemical education are discussed.

The aim of the article is to recall the fi steps of comprehension by the scientific community of possibilities of a newly born means of the reality reflection. The means was initially oriented for obtaining reliable information and supposing a delayed reaction of the spectator in the process of communication. Recollection and understanding become more important under the distance education condition. Pre-revolutionary Russia lived anticipating changes, and the filmmaking was considered by the society as one of those progressive phenomena evidencing the coming of a new age. The scientists’ activity during the development of scientific fi in pre-revolutionary Russia was long hushed up and wasn’t considered as forming a basis for the future system of educational audio-visual communication. In this process there participated striking, creative personalities, mostly belonged to the community of Imperial Moscow University, which activity was during the age of changes. The significant contribution of pleiad of eminent scientists’ activity to the new direction formation was a reason to unify in one paper both their whole professional life data and information about their time-limited period of scientific fi In the future a more profound study of their achievements are considered to be promising. In the introduction the anterior period of the Russian fi appearance, where the scientific and education community of Russia was exploring the possibilities of a new means of information transfer for education purposes, is considered. Two main units are dedicated to the role of scientists in the development of scientific filmmaking for research and popularization of biomedical and physical problems.

Introduction. In the course of their professional activities, traffic police inspectors of State Road Safety Inspectorate (SRSI) are exposed to harmful working conditions. The aim of study is to provide scientific justification for the periods of service of inspectors that are important for the diagnosis of early signs of professionally caused diseases. Materials and methods. The study was carried out in a group of traffic police inspectors of the traffic police in accordance with the ethical standards set forth in the Declaration of Helsinki, 1975 (with additions, 1983), a positive conclusion of the ethical committee. The age of the traffic police officers was 24-50 years old, the experience was 1-19 years (average values 34±0.46 and 8.21±0.40 years). Results. In the course of the study, a class of working conditions was determined-3.4. low-level traffic police officers showed signs of disadaptation, a high risk of morbidity with temporary disability and professionally caused pathology of the cardiovascular, musculoskeletal, nervous, endocrine, and digestive systems. Conclusions. It is advisable to conduct an in-depth preventive medical examination of inspectors after 1-2 years of service. The first 4 years of service are important for preventive measures.
