Multimedia and interactivity in distance learning of resuscitation guidelines: a randomised controlled trial

ABSTRACT The aim of the study was to conduct a comparative analysis of three forms of knowledge transfer online, taking into account the long-term knowledge growth rate and the satisfaction of students surveyed in respect to distance learning. The cohort of participants for this survey were students of the first degree, studying in the Emergency Medical Services. The authors created three e-learning courses in basic and advanced resuscitation procedures. The level of course participants’ satisfaction was analysed, as well as the knowledge growth rate measured three times: 7, 30 and 90 days, respectively, after finishing the course. The level of satisfaction in all the groups surveyed was comparable. The growth rate for knowledge was the highest in group C in the second and third survey, respectively (30 and 90 days after the end of the course), and a significant difference in favour of course C was demonstrated one month after finishing classes.

Using a Virtual Learning Environment as a Key to the Development of Innovative Medical Education

Abstract This article shows the organization of distance learning, particularly the idea of b-learning, combining the accomplishment of classes carried on in the traditional way and via computers. The authors present learning activities related to complementary education herein. Some of these course types may be successfully adapted to an e-learning background. The models and structure of the university virtual environment for distance learning are described. These illustrate a new approach to creating a virtual space for medical and technical studies where e-learning courses are created to be used for distance education, which allows students to be taught more effectively. The projected virtual courses for different groups of students ensure individualization of students’ work, which could be a relevant element for creating the shortest path of development of professional competencies. This paper further includes a brief overview of technologies used to build interactive elements into learning mate- rials. The authors present the use of interactive elements in medical education based on examples of certain selected games and animations.

Educational Multimedia Materials in Academic Medical Training

Abstract This article presents an overview of generally available applications for creating multimedia and interactive educational materials, such as presentations, instructional videos, self-tests and interactive repetitions. With the use of the presented tools, pilot materials were developed to support the teaching of biostatistics at a medical university. The authors conducted surveys among students of faculties of medicine in order to evaluate the materials used in terms of quality and usefulness. The article presents the analysis of the results obtained.

Implementation of e-learning portal for academic education and lifelong learning

Distance education is entering the area of university education with increasing strength, particularly including lifelong learning. Distance education requires a well-structured organisation and resource management tools, namely an e-learning portal. Universities which are still at the beginning of the portal implementation process may encounter numerous technical and organisational issues. This article was created with a view of educational centres in which the portal is implemented with scarce financial resources by several academic employees having little experience in the field. The authors point to several key issues, such as: analysis of the schools needs in terms of distance education server resources, choice of portal in terms of technology, supported standards or functions necessary for proper course and lastly, user management. The article also mentions the often-underestimated aspect of portal management. The authors further present the capabilities of computational clouds, their deployment in the academic environment and their use in distance learning. Such a solution is extremely rare, particularly in Eastern and Central European countries.

Creating Digital Question Databases: Use of Self-Tests in Teaching Medical Subjects

Abstract Enhancement of teaching using digital materials is rapidly entering the world of medical studies. Creation of a self-learning environment supported with self-tests is received well, or even enthusiastically, among students. On the other hand, there is a relatively large group of opponents among university teachers, who do not see the need for changes in teaching and testing methodology to be made. This attitude may be surfacing as a result of anxiety connected with implementing new technologies in teaching medical subjects, as well as the belief that implementing new technologies does not have an immediate effect on learning quality. The authors of this article attempt to demonstrate that a thoughtful choice of e-learning platform facilitates the process of implementing online learning and testing aids in medical faculties. The second part of the article presents initial results of studies concerning the efficiency of learning enhanced with self-tests. Our analysis details the results of exams in pathophysiology taken by students of the medical faculty at the Poznan University of Medical Sciences. After the course, an evaluation survey was completed by 195 students concerning the quality of teaching with the use of the OLAT (Online Learning and Training) e-learning portal. It showed that students had positive attitudes toward learning with the use of online materials, particularly with regard to the use of self-tests, which allowed students to check their knowledge independently in exam-like conditions. The article that follows is targeted at those teachers who are interested in implementing a self-study and electronic knowledge evaluation environment for their courses, not necessarily in medical subjects.

Evaluation of virtual environment as a form of interactive resuscitation exam

ABSTRACT There is scientific evidence confirming the effectiveness of e-learning within resuscitation, however, there is not enough research on modern examination techniques within the scope. The aim of the pilot research is to compare the exam results in the field of Advanced Life Support in a traditional (paper) and interactive (computer) form as well as to evaluate satisfaction of the participants. A survey was conducted which meant to evaluate satisfaction of exam participants. Statistical analysis of the collected data was conducted at a significance level of α = 0.05 using STATISTICS v. 12. Final results of the traditional exam (67.5% ± 15.8%) differed significantly (p < 0.001) from the results of the interactive exam (53.3% ± 13.7%). However, comparing the number of students who did not pass the exam (passing point at 51%), no significant differences (p = 0.13) were observed between the two types exams. The feedback accuracy as well as the presence of well-prepared interactive questions could influence the evaluation of satisfaction of taking part in the electronic test. Significant differences between the results of a traditional test and the one supported by Computer Based Learning system showed the possibility of achieving a more detailed competence verification in the field of resuscitation thanks to interactive solutions. GRAPHICAL ABSTRACT

Perspective of Dimensional Analysis in Medical Science

Abstract This paper presents several applications of the dimensional analysis method to problems investigated in medical sciences. The method is used to analyze various complex processes without using formal laws governing the same. It is particularly suitable for a general analysis of fluid transfer (liquids and gases) in the human body. This paper mainly serves as an overview of selected applications, mostly those emerging in the recent years, and includes a discussion of the mathematical fundamentals of dimensional analysis together followed by its critical analysis. Containing detailed calculations of two examples, the paper also serves as training material in the area of the computational method of the dimensional analysis algorithm.

Distance Learning Methods in Continuing Education of Paramedics

Abstract The process of continuing education of paramedics is based on gaining educational credits during five-year educational periods. One of the forms of self-improvement are Internet-based educational programs. The lack of regulations concerning the organizational and technical aspects of e-learning made the authors attempt to analyze the phenomenon. The aim of the article is to present an initial analysis of the role of online educational programs in comparison with other forms of professional training of paramedics. One in three respondents has recently used one of the methods of distance learning. Despite the low awareness of the effectiveness of e-learning, almost 70% of the interviewees expressed a positive opinion about it and over 50% were willing to use such forms in the future. The respondents preferred online trainings in the asynchronous version, containing audio-visual materials and providing the possibility to obtain a certificate issued to the participant after completing the course. The demand for topics in the area of professional training included mainly the fields of Drug Therapy, electrotherapy, electrocardiogram (ECG) evaluation, medical segregation, and help in delivery in pre-hospital conditions. Modern forms of distance learning do not make it possible to acquire practical skills, yet their role in professional training of paramedics is still significant. According to the authors, online educational programs constitute an effective complement to traditional training through the performance of tasks in a mixed form, known as blended-learning.

Higher Serum Hepatocyte Growth Factor Concentration is Associated with Better Preservation of GFR in Hemodialysis Patients

Background/Aims: Hemodialysis induces an intravascular inflammatory reaction which may further deteriorate renal function. We studied changes of serum interleukin 6 (IL6) and hepatocyte growth factor (HGF) concentrations during dialysis sessions, and at 12 month intervals. The synthesis of these cytokines in arterial endothelial cells in the presence of serum obtained from dialyzed patients was studied. Changes of the inflammatory reaction during 12 months of treatment were correlated with GFR. Methods: The study was performed on a group of 30 uremic patients treated with hemodialysis. Serum samples were collected before the start of dialysis, 15 minutes, and 4 hours later, when the session was finished. Serum levels of IL6 and HGF were measured with ELISA, as was the effect of serum samples on the synthesis of these cytokines in arterial endothelial cells. Results: At baseline hemodialysis induced an increase of serum IL6 (+10%) and HGF (+164%) levels at the end of the session. After 12 months of treatment predialysis serum IL 6 level was increased as compared to the beginning of the study (+22%), but no change in serum HGF level was observed. At that time the dialysis-induced rise of serum IL6 level was stronger than at the start (+18%), but the observed effect for HGF was weaker (+116%). An inverse correlation was observed between the dialysis-induced increase of HGF level and decrease of GFR after 12 months of study. The same relation was seen for HGF synthesis in the endothelium, but opposite for IL6 synthesis in the endothelium. Conclusions: We found that a higher HGF serum level during hemodialysis treatment is associated with a slower loss of residual renal function.

ICT Competencies for Academic E-Learning. Preparing Students for Distance Education - Authors’ Proposal

ABSTRACT Deployment of distance education (especially e-learning) at universities requires university teachers and students to have adequate ICT (Information and Communication Technologies) competencies. Schools usually provide training for their staff in operating e-learning portals and creating courses, which is the necessary minimum for conducting distance education. On the other hand, schools do not offer any courses for students to improve their competencies necessary for e-learning, as they assume that the students’ ICT competencies acquired during the three levels of schooling (elementary, lower secondary and upper secondary) are sufficient. The authors’ observations demonstrate that this assumption is not necessarily true, particularly for students at faculties related to humanities and other specializations not of technical nature, such as medicine. The article presents an overview of ICT competencies necessary for e-learning study, comparing them with competencies of a secondary school graduate. On the basis of a research project conducted at three medical universities in Poland, the authors present the level of knowledge and practical skills in the field of ICT among students who participated in e-learning or blended learning. As a result of the project, a proposal has been presented for modifying ICT education contents for students, as well as a draft course carried on the university’s LCMS (Learning Content Management System) portal to bridge the ICT competence gaps for effective distance education.
