Plan upravljanja istraživačkim podacima

U 21. veku razvoj tehnologije doneo je eksponencijalni rast količine podataka. Smatra se da je 90% trenutnih podataka u svetu generisano poslednjih pet godina. Nauka se, takođe, suočava sa novim mogućnostima kada su podaci u pitanju, posebno imajući u vidu da institucije koje finansiraju istraživanja, a pre svega se misli na istraživanja finansirana iz javnih fondova (publicly funded), postavljaju sve rigoroznije zahteve u pogledu čuvanja i deljenja podataka. Zbog toga je potrebno da se istraživači upoznaju sa formom Plana upravljanja podacima (Data Management Plan), njegovim značajem i elementima, kao i mogućnostima za automatsko generisanje finalne verzije plana upotrebom onlajn platformi

Assessment of Digital Skills in Serbia with Focus on Gender Gap

The world is constantly changing creating a new environment. One of the main factors in this process is the Digital Transformation which requires adjustment of skills, institutions, processes and business models. The European Commission started to cope with this topic in last twenty years and today their activities are according to the “Europe 2020 Strategy.” Enhancement of digital skills is one of the priority. Serbia also makes an effort in this area and policymakers already adopted several documents and policies. The main issue is a lack of scientific research that cover the subject – ex ante and ex-post analysis of adopted policies. We consider this subject very important having in mind that the digital skills become one of the basic element for the national growth and competitiveness. This paper presents findings on the existing level of digital skills of the workforce in Serbia, with focus on the gender gap. Findings are based on a standardized survey conducted during September 2017, within the pilot study research. Results show that the level of digital skills is Serbia is lagging behind the EU average and that the level of digital skills of Serbian women is lower than men

Good preparation of data before archiving and publishing will allow reuse of the data and provide better scientific engagement. In this paper, authors will be focused on processes that have to be taken before archiving and publishing. Also, some of the main activities will be highlighted, in order to raise awareness about the importance of this topic

The application of expectancy-value theory in explaining academic procrastination in physics

Ciljevi ovog istraživanja bili su ispitati rodne razlike između učenika u prethodnoj uspješnosti iz fizike, subjektivnoj vrijednosti fizike, njihovoj samoefikasnosti i akademskom odlaganju u ovom predmetu te provjeriti postoji li medijatorna uloga samoefikasnosti i subjektivne vrijednosti u odnosu između prethodne uspješnosti iz fizike i akademskog odlaganja. U istraživanju je sudjelovalo 285 učenika drugih i trećih razreda dviju zagrebačkih gimnazija, a kao teorijski okvir istraživanja korišten je model očekivanja i vrijednosti Eccles i suradnika (1983). Primijenjeni su instrumenti koji mjere samoefikasnost učenika, četiri komponente subjektivne vrijednosti (interes, važnost, korisnost i cijenu truda) i akademsko odlaganje. Rezultati su pokazali da učenici i učenice podjednako odlažu učenje fizike te da se ne razlikuju značajno u prethodnoj uspješnosti u fizici. Nadalje, komponente vrijednosti zadatka (interes, važnost i korisnost) koju učenice pridaju fizici značajno su niže od one od učenika. Uz to, djevojke se procjenjuju značajno manje samoefikasnima te je za njih cijena truda za učenje fizike značajno viša. Prethodna uspješnost, subjektivna vrijednost i samoefikasnost u negativnoj su korelaciji s akademskim odlaganjem, dok je cijena truda u pozitivnoj korelaciji. Rezultati medijacijske analize pokazali su da cijena truda kao samostalna komponenta subjektivne vrijednosti ima medijatornu ulogu u odnosu između prethodne uspješnosti i akademskog odlaganja, dok se za samoefikasnost i ostale komponente subjektivne vrijednosti takva veza nije pokazala.Aims of this study were to examine gender differences between male and female students when it comes to their past performance in physics, subjective task value, their self-efficacy and academic procrastination and to examine whether self-efficacy and subjective value play a mediator role in the relationship between the students` past performance in physics and the academic procrastination of learning physics. The participants were 285 high school students (grades 2 and 3) in Zagreb. As a theoretical framework for the research Eccles and colleagues’ (1983) expectancy-value model was used. The instruments used in the study measured students' self-efficacy beliefs, four components of subjective task value (attainment value, intrinsic value, utility value and costs) and academic procrastination. The results indicate that male and female students procrastinate equally and do not differ significantly in their past performance in physics. Furthermore, task values (attainment value, intrinsic value, utility value) of physics are significantly lower for female students than for male students. Additionally, female students have lower self-efficacy in physics and their perceived cost is significantly higher. Past performance, subjective task value, and self-efficacy were in negative correlation with academic procrastination, while their perceived cost is in positive correlation. The results of the mediation analysis indicate that the perceived cost, as an independent component of subjective task value, has a mediating role in the relationship between past performance and academic procrastination, whereas self-efficacy and other components of subjective task value do not show such a relation

Repozitorijumi: digitalni resursi savremenog obrazovanja

Digitalizacija, podržana razvojem World Wide Web-a, već decenijama transformiše procese obrazovanja i naučnog rada. U ovom radu akcenat je postavljen na promeni koja je nastala u načinu pristupanja rezultatima naučnog rada. Tradicionalni način diseminacije rezultata, baziran na štampanim medijima (časopisi, monografije, zbornici, izveštaji, podaci i slično) pokazao je značajne nedostatke, a među najvažnijim je nemogućnost globalnog pristupa i jednostavne replikacije (posebno relevantno u slučaju podataka). Da bi se prevazišla navedena ograničenja uvode se digitalni repozitorijumi, odnosno sistemi dizajnirani za prikupljanje, organizovanje, skladištenje i deljenje digitalnih sadržaja. Osnovna namena digitalnih repozitorijuma je da čuvaju i stave na uvid odabrane rezultate, čime oni postaju javno dostupni i globalno vidljivi, ali i sačuvani u formatu koji odoleva tehnološkom napretku. Jedna od najvažnijih karakteristika digitalnih repozitorijuma je mogućnost pristupa sa bilo kog mesta, u bilo koje vreme, tako da ključni akteri obrazovnog procesa, nastavnici i studenti imaju mogućnost pristupa rezultatima naučnog rada. Posebnu pogodnost predstavljaju repozitorijumi koji se nalaze u režimu Otvorenog pristupa (Open Access), pri čemu je važno istaći da Republika Srbija podržava ovaj koncept. Digitalni repozitorijumi se mogu grubo podeliti na dve velike grupe, na repozitorijume radova (publikacija) i repozitorijume podataka (skupova ili setova podataka). Rad se oslanja na studiju slučaja i pozitivno iskustvo Instituta ekonomskih nauka koji od 2015. godine razvija institucionalni repozitorijum radova – IRIES i Centar podataka u društvenim naukama RS (SER-DAC) - repozitorijum skupova podataka, koji je inicijalno započeo razvoj 2012. godine, kroz realizaciju FP7 projekta SERSCIDA

Collaborative creativity in elementary school music teaching

Socio-kulturološka dimenzija kreativnosti nezaobilazni je aspekt u teorijskim razmatranjima fenomena glazbene kreativnosti. Empirijska istraživanja i iskustva iz prakse dovela su do potrebe za rekonceptualizacijom i reinterpretacijom pojma glazbene kreativnosti u obrazovanju. Upravo se kroz socio-kulturološki kontekst razvio i pojam ‘kolaborativna kreativnost’ (eng. collaborative creativity). U školskoj praksi kolaborativna se kreativnost može ostvariti među učenicima, ali i među nastavnicima koji surađuju kroz realiziranje integrativne nastave, izvannastavnih aktivnosti i projektne nastave. U ovom radu predstavit će se neki oblici poticanja kolaborativne glazbene kreativnosti, s posebnim osvrtom na iskustvo učenika i utjecaj koji su zajednički stvaralački procesi imali na njihovu socijalizaciju, motivaciju, ali i na praktičnu primjenu usvojenih znanja. Za metodološki okvir iskorišteno je akcijsko istraživanje provedeno u jednom odjeljenju petog razreda osnovne škole tijekom školske godine 2017./2018. Cilj rada je otvoriti pitanja o mogućnostima poticanja kolaborativne kreativnosti u redovitoj nastavi glazbe, ali i ukazati na objektivne poteškoće za realizaciju ovog oblika kreativnog procesa u školskim uvjetima.The socio-cultural dimension of creativity is an essential aspect of theoretical examinations of the phenomenon of musical creativity. Empirical research and practical experience have resulted in the need to reconceptualise and reinterpret the concept of musical creativity in education. The concept of collaborative creativity developed through the socio-cultural context itself. In school practice, collaborative creativity can be achieved among pupils, as well as among teachers who cooperate through integrative teaching, extracurricular activities, and project teaching. This paper will present some ways in which to encourage collaborative musical creativity, with a special view to student experiences and the influence that collaborative creative processes have on their socialisation, motivation, and the practical implementation of acquired knowledge. The action research methodological framework was implemented in a Year 5 elementary school class during the 2017/2018 school year. The goal of the paper is to examine the potential for encouraging collaborative creativity in regular music teaching, as well as to indicate objective difficulties in undertaking this type of creative process in schools

IMPORTANCE, STRUCTURE AND OUTCOMES OF THE MUSIC PROGRAM IN THE PRIMARY SCHOOL: THE EXPERIENCE OF CROATIA, MONTENEGRO, AND SERBIA

In an effort to look into the importance and structure of the program through a simultaneous analysis of the achievement outcomes for the Music course in three countries – Croatia, Montenegro, and Serbia, the authors have performed a detailed analysis of a number of documents covering the topic in these countries. A comparative analysis of the contents of these documents has provided us with the opportunity to assess the speed at which the educational systems in the three countries are being reformed, the differences in the approach to individual areas, but also the need to provide joint theoretical efforts whose goal would be to foster what is the common denominator for us all – a promoted process of teaching music which would provide a simultaneous development of students’ artistic identity.&nbsp

Oxidative stress in athletes: From the scientific basis to practical aspects

Oxidative stress, which occurs as a result of physical exercise, has been intensively investigated in the last two decades. A large number of studies have been done on humans and in animal models, which resulted in clarification of the mechanism of free radical generation during exercise. Free radicals, unstable and reactive molecules that can be involved in cellular damage, are mainly generated by the mitochondria, xanthine oxidase, and neutrophils and other phagocytes. Increased production of free radicals during exercise is followed by the enhanced activity of the endogenous antioxidant defense system, which consists of enzymes and non-enzymatic substances. Very important results of previous studies have been related to adaptation mechanisms activated in response to increased oxidative stress during exercise. In addition to mitochondrial biogenesis and synthesis of new components of the respiratory chain to match higher energy demands, adaptation to regular physical exercise involves an increased expression of genes responsible for antioxidant enzyme synthesis. Also, great attention has been paid to the use of antioxidant supplements. The importance and effect of supplementation with dietary antioxidants depend on several factors such as intensity, frequency and mode of exercise as well as on the type and dose of the antioxidants used. Applying the results of previous research and monitoring the parameters of oxidative stress and antioxidative defense could help health professionals in understanding the medical condition of the athlete

Naglasak pridjeva u govornoj praksi

U radu se analiziraju odstupanja od kodificirane naglasne norme u govornoj praksi na korpusu čestouporabnih pridjeva. Odstupanja su zabilježena i na leksičkoj i na paradigmatskoj, pa onda i na tipološkoj razini. Uočavaju se tendencije dokidanja međuslogovnih naglasnih preinaka, tonske opreke kratkih slogova, tendencija širenja distribucijskoga polja silaznih naglasaka, jaka tendencija pomicanja naglaska prema početku riječi te gubljenja zanaglasnih dužina. Neke od njih nalazimo već i u suvremenim priručnicima
