    Background. The aim of the study was to identify the organization of physical education in the new core curriculum. The research material consists of the professional qualifications of 32 physical education teachers, the sports infrastructure and the method of the physical education implementation were diagnosed. Material and methods. The primary research method was a diagnostic survey and survey technique. Moreover, a teacher personal questionnaire of physical culture and a questionnaire to assess working conditions for the implementation of school physical education were applied. To identify how to implement physical education classes in schools and how to offer a variety of classes for the students to choose from, a personal questionnaire (RZWF) was used. It was created independently on the basis of the Decree of the Minister of National Education of 23 December 2008 on the core curriculum and general education in particular types of schools. Results. The study which diagnosed the professional qualifications of the physical education teachers showed that all of them graduated from the University School of Physical Education, and the highest percentage of the teachers have been working for over 21 years. Half of the diagnosed teachers have a chartered teacher status. Half of the teachers have at least an instructor certificate in a single discipline. Among those teachers, most people have a coach or instructor licence to conduct classes in basketball, volleyball, swimming, soccer and downhill skiing. The study on the diagnosis of the ways of implementing physical education classes showed that five secondary schools implemented a traditional classroom- lesson system, and four schools – a mixed system (classes in the classroom-lesson system, and activities to be chosen by a student). Conclusions. The research has shown that in more than half of the diagnosed secondary schools in Wroclaw some new opportunities for the organization of physical education have been introduced.

    ‘edubal’ educational balls
    Opis:
    The aim of this study was to sum up the experiences gained during twelve-year research on effects of using educational balls called ‘edubal’ in PE classes in grades 1 to 3 of the primary school (i.e. children aged 7 to 10). The research was carried out in Poland an in Germany. The authors focused their attention on objectives and tasks of contemporary education of children aged 7 to 10 – first of all supporting and stimulating comprehensive development of children, especially with regard to improving coordinative motor abilities which determine, inter alia, reading and writing skills. Employment of ‘edubal’ education balls in early school education (grades 1 to 3 of the primary school) activates cognitive, emotional and physical spheres of a child and hence contributes to the integration of the subject content. The children while participating in PE classes with the use of education balls learn about letters, spelling rules, colours, mathematical signs and punctuation marks as well as numerous rules which are useful in linguistic and mathematical education and they shape their coordination abilities and improve physical skills. Moreover, they also develop their coordination abilities. ‘Edubal’ education balls have a much wider scope of application than it was the case twelve years ago. They are also used in occupational therapy of disabled persons and in work with dyslectic children who attend therapeutic schools.

    Background. The aim of the study is to verify relations between movement classes with the use of the educational balls “edubal” and the ability to write in lines in 1st grade students of elementary school. Material and methods. The study diagnosed 43 students (23 girls and 20 boys) from elementary school in Czarny Bór. Data were collected by means of a pedagogical experiment carried out with in parallel group technique (experimental and control group). The experimental factor was the program of physical activity classes integrated with teaching program in elementary school. The experimental group used the education balls “edubal” twice a week for 45 minutes. At the beginning and at the end of the school year “The pedagogical method of examination of reading and writing skills for grades I–III of primary school” by Straburzyńska and Śliwińska was used to evaluate students’ writing skills. Results. The research proved that the students from the experimental group significantly improved their writing skills and achieved better results than those from the control group. Girls made less mistakes than boys. Conclusion. The physical activities with the use of the educational balls “edubal” improve the elementary school students’ ability to write in lines. There are differences in the students’ writing skills performance based on sex.

    Background. Time-space orientation is one of the specific coordination motor abilities. To a large extent, it is genetically conditioned by neurosensory and psychic abilities. Time-space orientation has significant impact on adaptation to rooms of various sizes, perception of obstacles, identifying space patterns, objects and distance. The purpose of this study was to compare level of time-space orientation of students with specific learning difficulties such as dyslexia, dysgraphia and dyscalculia with their peers (without learning disabilities). Material and methods. The research sample included 40 third grade students of two primary schools (18 students from Therapeutic Primary School No. 11 and 22 students from Primary School No. 15 in Wroclaw). In order to determine the level of time-space orientation, a modified Reactive Shuttle Drill test and the research tool Smart Speed System, (similar to that described by Ljach – “run for a ball”, 2003) were used. Results. students (both boys and girls) without any learning disabilities obtained better results. They were not statistically significant. When comparing boys’ and girls’ results, those of statistical significance appeared only in the second test.

The aim of our study was to examine the interest in physical activity of the students from selected secondary schools in Wroclaw. Material and methods. The study comprised 197 students (112 girls and 85 boys) from 2 secondary schools in Wrocław. A diagnostic opinion poll and standardized survey questionnaire “Students’ interest in physical activity” were used. Results. The research proved that most of the students were interested in swimming, dancing and sport games. Among girls the most popular were dancing, swimming and skiing, while boys were interested in sport games, motor sports, swimming and martial arts. Conclusion. The results showed that physical education classes in secondary schools should include the most popular forms of students’ physical activity. Secondary schools should examine the students’ interests in physical activity and incorporate the most popular sport disciplines into physical activity classes.

    Introduction. During P.E. classes primary school students (grade 4) ought to improve their level of physical fitness, including coordinative motor abilities, as well as to acquire motor skills which enable them to take part in various forms of physical activity in an active and safe way. Unfortunately, in physical education of children and young people the main emphasis is still placed on the improvement of fitness abilities. We have to bear in mind, however, that the level of coordinative abilities limits significantly the improvement of necessary fitness abilities and vice versa. Our research was aimed at determining what dependencies exist between the results of selected coordinative motor abilities and ten-year-old children’ results of the tests designed by the International Committee for the Standardization of Physical Fitness Tests. Material and methods. The research group consisted of 93 students of primary schools in the town of Wołów. In order to determine the level of the particular components of physical fitness we employed the trials of the International Committee for the Standardization of Physical Fitness Tests (ICSPFT). For assessing the particular coordinative abilities we used the following tests: ‘run for the balls’, ‘stopping the rolling ball’, ‘long standing jump with 50% of maximum possibilities’, ‘long standing jump forward and backward’. Results. According to research findings there is a relationship between the improvement of the selected coordinative motor abilities and some of the components of physical fitness. Conclusions. Therefore, a physical education teacher are advised caution in choosing physical exercises and games, taking into consideration comprehensive motor development of students, including their coordinative motor abilities.

    Purpose. Forms of physical activity people take up depend on sex, place of residence, age, season of the year and many other factors. The aim of the study was to find out what forms of physical activity senior high school students in Wrocław are interested in, and analyze them. It was assumed hypothetically that their interests depend upon sex, age and school the participants attended. In order to verify this hypothesis, the following research questions were posed: 1. Which forms of physical activity are senior high school students in Wrocław interested in? 2. Which of them are girls interested in and which are boys interested in? 3. Which forms of physical activity are students in various grades interested in (grades one, two and three)? 4. Which forms of physical activity are students of one school interested in and do they differ from those of students attending other schools? 5. Do interests in forms of physical activity depend upon age, sex and school? Methods. The study comprised 789 students (486 girls and 303 boys) of grades 1–3 of six senior high schools in Wrocław. The basic research method was a diagnostic survey and the technique was a questionnaire. For the purpose of determining their interests in forms of physical activity, a standardized survey questionnaire was used: ‘Interests in the scope of physical activity’.

    Opis:
    In modern endurance training information about an athlete’s performance below and above the anaerobic threshold is crucial. The aim of the present study was a comparative analysis of the total distance covered by football players in two rounds of the 2013/1014 playing season. Furthermore, the study also assessed the performance of elite Bundesliga players during competitive matches, above and below the running speed of 4 m·s –1, corresponding to the level of anaerobic threshold (AT). The players’ mean body height was 183.00 ±6.44 cm, body mass 78.19 ±7.42 kg, and mean age was 27.99 ±3.47 years. The analysis was carried using the Impire AG motion analysis system on the basis of official match reports from the Deutscher Fußball-Bund (DFB). The study revealed that the total distance covered by the players in match-play was significantly shorter in the second round of the playing season. The distance covered by the players below the AT is significantly shorter in the spring round than in the autumn round, while the distance covered above the AT shows a reverse, although non-significant tendency. In the spring round the volume of players’ work performed above the anaerobic threshold is greater than the volume of exercise performed below the AT.

    Opis:
    Neuroblastoma, the most common extracranial solid tumour of childhood, is a malignancy of unknown origin and non-specific symptoms. One of the markers of the disease is GD2 ganglioside (disialoganglioside), which is abundantly expressed on the surface of neuroblastoma cells. Gangliosides are known to be shed by tumour cells and this phenomenon can be significant in cancer progression as they inhibit a number of immune responses both in vitro and in vivo. In search for novel markers useful in monitoring and prognosis of neuroblastoma, we developed and validated a new quantitative method of GD2 ganglioside analysis in human blood plasma. We evaluated the level of gangliosides in blood serum of 34 neuroblastoma patients using high-performance liquid chromatography. The technique was used to detect fluorescently labelled oligosaccharides derived from serum glycosphingolipids by enzymatic digestion with ceramide glycanase. The developed method allowed determination of GD2 concentrations at the picomole level and required only 40 µl of plasma, which should be particularly useful when the quantity of clinical material is limiting. Moreover, this method can be applied to study concentration of other gangliosides, as shown for GD3 ganglioside. Analysis of plasma samples from the 34 neuroblastoma patients did not reveal any correlations between the concentration of GD2 ganglioside and clinical parameters, including the results of therapy; it showed, however, that the concentration of GD2 ganglioside in the plasma of neuroblastoma patients decreased substantially in the course of treatment.

    Opis:
    Redakcja Zarania Śląskiego zwróciła się do 50 badaczy wywodzących się z różnych środowisk i pochodzących z różnych części naszego województwa z prośbą o odpowiedź na pytanie: „Jakie wydarzenia historyczne z perspektywy obecnego województwa śląskiego uznaje Pani/Pan za najważniejsze”? Prosiliśmy o wytypowanie pięciu najważniejszych wydarzeń oraz krótkie wyjaśnienie wyboru, pozostawiając autorom całkowitą swobodę w konstrukcji tekstu uzasadnienia. Sugerowaliśmy jedynie, by ograniczając się do terytorium obecnego województwa śląskiego, nie zawężać poszukiwań do ram czasowych, w których zostało ono stworzone. Respondenci wybrali wydarzenia tak różne, że trudno pokusić się o podsumowanie. Wyrażamy nadzieję, iż wnioski nasuwające się czytelnikowi przyczynią się do refleksji – a może wręcz wywołają dyskusję – nad skomplikowanymi dziejami regionu. Respondenci byli proszeni o sformułowanie krótkiej wypowiedzi. W tym miejscu publikujemy wersje skrócone tych tekstów, które przekraczały sugerowaną objętość. W Suplemencie znaleźć można wersje autorskie.
