Situational problems in the formation of professional competence of specialists in specialty “Urology”

A modern activity has indicated the vector for the future development. Therefore, for the establishment of clinical thinking, encouragement of the young specialists, disclosure of initiative, orientation in time among a wide informational access, it is set the question of “interdisciplinary links”, and as a result an ability to choose the most effective methods from suggested in the modern environment. Interdisciplinary tasks integrate discipline “Urology” in educational and training complex. Implementation of the knowledge of this type is a method of improvement for mastering of the basic medical sciences and further related subjects. Promotion of the clinical thinking formation not in the medical chairs, but right from the beginning of the education. On the advance training cycles, these tasks mostly require a review of the forgotten material of the past years related to the basic disciplines and improvement of these for the integration in phased interdisciplinary tasks. In the process of resolution professional choice is differentiated, and a continuous improvement in this direction. The tasks themselves represent “perforated” tasks (those that contain data, resolution of which requires the involvement of knowledge not in the single discipline, but in a complex way, which corresponds more to practical application then to the theoretical) moreover, a grading approach is applied for the determination of the probationer’s readiness. The possibility of independent resolution of complicated clinical tasks and handling of latest technologies are only possible by summation of efforts of related teachers. Implementation of interdisciplinary tasks increases mastering of basic sciences as well as of the clinical disciplines in the future, and the ability to respond today’s social needs. Resolution of these tasks requires a review in the memory of today’s acquired material and so, its fixation in the further usage.

OPTIMISATION OF SELECTION OF ELECTRONIC LEARNING RESOURCES ACCORDING TO STUDENT GROUP COMPOSITION

The technology of integration of learning methods, forms and means of information and communication technologies is described with due regards for psychological and pedagogical characteristics of student groups. The results of theoretical and experimental research conducted on the basis of two Ukrainian universities with the participation of 341 students in the "Chemistry" training area and 18 lecturers of basic chemical disciplines are highlighted. Both students and lecturers were polled in a specially designed questionnaire to show their attitude to the use of various electronic learning resources in learning and teaching basic chemical disciplines. Students’ preferences in learning styles were estimated on the basis of a self-scoring questionnaire for assessing preferences on four complementary dimensions, such as perception (sensitive or intuitive), input (visual or verbal), processing (active or reflective) and understanding (sequential or global) of chemical information. Such an approach is known as the method of Felder-Soloman, and it allows one to calculate Indices of Learning Style which assess qualitatively available preferences of all respondents in each of the four available directions. The developed technology allows lecturers to qualify an optimal set of electronic learning resources for the teaching of individual sections of chemistry, taking into account preferences in their use of students with different learning styles. The technology under development is based on the calculation of average resource scores as assessed by all students in the group, as well as on the expert evaluation of the feasibility of their application in the teaching of basic chemical disciplines. The taxonomy of the optimal selection of electronic learning resources and teaching methods is developed for each type of students’ learning preferences. Advantages and disadvantages of all available variants of the application of the developed technology are discussed for student groups of different compositions. An example of the application is given for studying the discipline "Inorganic Chemistry".

Professional Silos or Professional Integration? Exploring the role of the basic science disciplines in healthcare professionals' professional identities.

This article was migrated. The article was marked as recommended. Professional identity (PI) is an important topic within modern healthcare curricula; presently, explorations of this topic focus on the impact of clinical experience. We sought to explore the impact of science education on PI from healthcare practitioners' perspectives using a qualitative approach. While this work is still in relative infancy, we found an unexpected outcome - that healthcare workers perceive their science knowledge as a central component of their PI. This work begins to unpack the complicated and previously poorly explored interplay between the sciences and clinical contexts have on practitioners' PI. Progression of this research area may help improve integration and explicit linking of healthcare sciences with both clinical education and PI development.

EFFECTIVENESS OF E-LEARNING RESOURCES IN PHYSICAL CHEMISTRY TEACHING

Implementation of electronic learning resources into the teaching of chemical disciplines in higher school does not always lead to an improvement in students' mastery of the material. Therefore, the optimal choice of effective electronic resources for the teaching of basic chemical disciplines is an urgent task. The purpose of the work was to identify the resources that are relevant to the teaching of physical chemistry from the point of view of both teachers and students. Specific questionnaires were developed to achieve the goal, and a survey of pedagogical process participants (students and faculty members) was conducted, followed by statistical processing of the survey results. The expediency of usage of 41 e-resources was investigated, and 21 resources were identified as suitable for the study of a university course in physical chemistry. Among them, eight e-resources were found to be important for teaching most topics of the discipline, and so are attributed to universal resources. Another thirteen resources are important for teaching some topics and ineffective for others (specific resources). At the same time, only five universal and eight specific resources are currently used in the practice of the Faculty of Chemistry of Olesj Honchar Dnipropetrovsk National University. Some discrepancies have been identified between teachers and students concerning resource preferences that create the preconditions for the loss of effectiveness of the use of such resources. Since the use of some electronic resources is sensitive to learning styles, existing styles for faculties and students were analysed. The main differences consist in the explicit preferences of the faculty for reflective and global styles, while students are characterised by predominantly active and sequential learning styles. The results obtained regarding the effectiveness of e-resource usage are discussed from the viewpoint of preferences in learning styles characteristic of students and teachers of natural sciences.

Innate and Adaptive Immune Response to a Virus: An Integrated Learning Module.

Medical schools must expand their teaching strategies to address a new generation of medical students and ensure their growth into lifelong, self-directed learners. Integration across basic science disciplines packaged together with clinical medicine produces learning materials that better enable medical students to achieve these goals. We created a narrated audiovisual learning module illustrating the foundational sciences and clinical presentation surrounding immune responses to viral infections. We integrated immunology, microbiology, histology, pathology, and clinical medicine and included a self-assessment quiz and clinical vignette with questions to test students' understanding of the material. We published the module on our school's learning management system and tracked student usage, which was followed by an in-class survey to assess student perceptions of the usefulness of the module. Sixty-four (59%) of the first-year medical students used the module. Thirty-seven students completed the in-class survey assessing their perceptions of the module. Over 95% of responders reported that the module helped them learn the new material, identify areas of weakness, understand the big picture for this immune response, and apply the material in a clinical context. This module illustrates an approach to integrating basic science disciplines in order to facilitate students' understanding of the mechanisms underlying patients' clinical presentations. Survey results indicated that students valued the module as a self-directed learning component that integrated essential clinical concepts. The module was a helpful tool for students to evaluate their comprehension of immunology in a clinical context and can be used as required or optional material.

A pedagogical case on active learning regarding to Kirchhoff's circuit laws

Kirchhoff’s circuit laws are important basic concepts in many basic disciplines, such as electricity and circuitry. However, in the usual teaching process, teachers often teach this knowledge using some simple examples of analysis and calculation but without deep discussions. As a result, students could not have a deep understanding about these concepts or not apply the concepts on actual problems flexibly. Therefore, passive learning habits are formed. The lack of self-exploration awareness and comprehensive ability would result in a poor learning effect. This paper designs a specific application scene of Kirchhoff’s circuit laws using a multi-channel resistor network. With this application, students can construct the knowledge system autonomously, find the problems proactively, solve the problems timely, and combine the research-based autonomous learning with extracurricular open mutual learning; so, their active learning ability will be promoted to a large extent. Compared with the past teaching methods, this pedagogical case highlights the following advantages of active learning. Firstly, it highlights the process of guiding students to study the object from a small-scale resistor network to a complex and large-scale multi-channel resistor network. Secondly, it embodies the concrete application of calculus knowledge in various basic courses with the help of perfect mathematical deduction. Thirdly, it exercises students’ programming ability by using MATLAB to numerically simulate theoretical results. Finally, this case practices students’ hands-on experimental ability by constructing real resistor circuits and verifying the theory and simulation results. In addition, we get good feedback from students on the teaching effect through the questionnaire survey.

Concept Animation - a potential instructional scaffolding

This article was migrated. The article was marked as recommended. Concept animation - the graphical array of pictures accompanied by text as speech balloons, can help to improve learner's comprehension from basic to advanced levels concepts. When the process of concept comprehension is not facilitated, the learner may come in a transitional state of misperception and understanding, that can restrain their learning to a surface approach. The basic science concepts learned at the inception of a Health Sciences program play a vital role towards the development of higher-order thinking and problem-solving aptitude in the subsequent years. Hence, it is important to facilitate meaningful learning of core concepts and principles in difficult basic science disciplines, like Pharmacology. This work reports our experiences of employing concept animations as a 'visual aid' instructional strategy to simplify pharmacology concepts to undergraduate Optometry students. The fundamental ideas of drug pharmacokinetics, pharmacodynamics and side effects were transformed into concept animations. The effects of these concept animations are explained by using Vygotsky's 'zone of proximal development, Mayer's cognitive theory of multimedia learning and cognitive load theory.

Vertical Integration in Clinical Years of Medical Education

Background: Integration is one of the main principles of contemporary medical education. Horizontal integration necessitates the coordination of teaching and learning activities within a year or a block, while vertical integration can be achieved by the contribution of basic and clinical sciences in all phases of medical education. Although vertical integration is achieved in many programs during the first 2-3 years (pre-clinical years), it is usually disregarded in clinical clerkships.Methods: A clinical-basic science integration (CBSI) program was implemented at Alfaisal University College of Medicine during 4th year clerkships of Surgery, Obstetrics-Gynecology and Internal Medicine and the topics discussed were related to those clerkships. The basic sciences disciplines involved were: microbiology, pathology and pharmacology.Results: A five points Likert scale questionnaire was used to collect the results of the students. There was a satisfaction level of over 80% for most of the questions and topics.Conclusion: Basic and clinical science integration (correlation) sessions are the way to complement vertical integration in clinical years. Integrated sessions should be planned and implemented in all clerkships with appropriate basic science topics. In order to ensure complete integration, these sessions should be coordinated by a team of basic scientists and clinicians.

Perception of Ghanaian Medical Students of Cadaveric Dissection in a Problem-Based Learning Curriculum

There is a drastic shift in medical curriculum from the traditional medical curriculum where various basic science disciplines are taught separately in the preclinical years to integrated problem-based learning (PBL) in many medical schools across the world. In the integrated PBL, the time for classical anatomy dissection is significantly reduced. There are varying views across the world about the perception of medical students to cadaveric dissection. There is however no research on student's perception of cadaveric dissection in Ghana. The present study was to assess Ghanaian medical student's perception of cadaveric dissection under the PBL curriculum and to assess which educational tool students rely on to study anatomy. An anonymous self-administered, Likert-style questionnaire consisting of 24 questions was administered to 132 second- and third-year students after they had completed the dissection schedules for the musculoskeletal system. Participation was voluntary. In all, 89.5% of the students indicated that they had attended all the dissection sessions. The students generally agreed that dissection deepens their understanding of anatomy (87.9%), provides better understanding of clinical skill examination (66.7%), enhances their respect towards the human body (66.6%), provides better understanding of the effect of trauma (69.7%), and makes learning interesting (90.9). However, 57.5% of them agreed or strongly agreed that dissection was stressful. Majority of the students also disagreed that dissection should be eliminated from the curriculum (100%). This study has shown a strong positive perception towards the use of cadaveric dissections in teaching and learning anatomy regardless of the fact that SMHS/UDS uses the integrated PBL curriculum.

The Four Horsemen and the American Board of Psychiatry and Neurology (ABPN)

ABSTRACTAfter the gradual introduction of specialties in medicine in the United States during the late-nineteenth and early-twentieth centuries, the American Board of Psychiatry and Neurology (ABPN) was founded in 1934 to provide specialty regulation (training oversight, examination, and certification). The name reflects the combined practice of psychiatry and neurology that was still present at the time. Directors were nominated by the founding organizations: American Psychiatry Association (APA), American Neurological Association (ANA), and the Section of Nervous and Mental Diseases of the American Medical Association (AMA). Many of the early physicians who were certified by the ABPN did so for psychiatry as well as neurology. Neurologist Walter Freeman and psychiatrist Adolph Meyer played important roles in the ABPN during the early days. Following the founding of the AAN in 1948, neurological practitioners believed the AAN would better represent them in the ABPN. At first the ANA appointed AAN members to the ANA Council; but after 1972, the AAN could directly nominate directors for the ABPN. Despite this situation, the AAN had an important influence in the ABPN from its start, as is shown by the fact that all of the key organizational leaders responsible for founding the AAN—the “Four Horsemen” (Abraham B. Baker, Russell N. DeJong, Francis M. Forster, and Adolph L. Sahs—served as directors of the ABPN in the period 1951–1967. The Horsemen were able to change both examination practices that became more searching and expansive, and the basic disciplines that needed to be studied in detail.

A theoretical framework of urban systems and their evolution: The GUSE theory and its simulation test

City, urban systems and their evolution are classical interdisciplinary issues in urban studies. Most traditional classical theories have different drawbacks because of the inherent limitations of their basic disciplines. Therefore, a general theoretical framework is urgently needed to interpret city, urban systems and their evolution. This study proposed a novel theoretical framework of urban systems and their evolution (the GUSE theory) to explain the processes and features of origin, spatial pattern and evolution of regional urban systems. We firstly proposed definitions of coverage, city and urban system based on Graph Theory method; then built models and indices to interpret and evaluate growth and evolution of urban system by combining the model of spatial interaction flow with the “urban tree (UT)” hypothesis. Numerical simulation is finally conducted to illustrate the GUSE theory and verify the stability of the proposed models. The GUSE theory in this study can provide significant theoretical basis for regional research, such as urban system study and planning.
