No full textThe focusing properties of diffractive lenses designed using the Fibonacci sequence
are studied. It is demonstrated that these lenses present two equal intensity foci and
that the ratio of the two focal distances approaches the golden mean. This distinctive optical
characteristic is experimentally confirmed. It is suggested that the versatility and potential
scalability of these lenses may allow for new applications ranging from X-ray microscopy to
THz imaging.This work was supported in part by the Ministerio de Economia y Competitividad under Grants FIS2011-23175 and TRA2009-0215, by the Generalitat Valenciana under Grant PROMETEO2009-077, and by the Universitat Politecnica de Valencia, Spain, under Grants PAID-05-11 and SP20120569.

RESEARCH PURPOSE : This article describes the further validity and reliability assessment of the Adult Learner Self-Directedness Scale (ALSDS), which assesses adult learners' academic self-directedness in an open, distance and e-learning (ODeL) university in South Africa. An initial validity and reliability study yielded a four-factor scale with 35 items loading onto it, while this study reports on a three-factor scale with 15 items loading onto it.
MOTIVATION FOR THE STUDY : Factors such as socio-economic conditions and past education practices make South African open, distance and e-learning higher education (ODeLHE) challenging for socio-economically disadvantaged students. The growing trend of online tuition and assessment in South African universities requires research into strategies that may improve a student's success and throughput. In ODeLHE, student self-directedness may contribute to academic success, and thus a reliable scale is needed to assess it. Currently, there is no such South African scale.
RESEARCH APPROACH/DESIGN AND METHOD : A quantitative, cross-sectional research design was implemented, using self-report data from the students of the College of Economic and Management Sciences at a South African ODeL university. The ALSDS comprises three factors: success orientation for ODeLHE (self-efficacy beliefs), active academic behaviour (learner agency) and use of strategic resources (learning context management).
MAIN FINDINGS : The findings indicate that the ALSDS appears to be a valid, internally consistent and reliable scale suitable for assessing ODeLHE adult learners' academic self-directedness. Further research is, however, required to establish metric and scalar invariance
PRACTICAL/MANAGERIAL IMPLICATIONS : The scale may provide a reliable starting point for developing a scale for assessing ODeLHE students' existing academic self-directedness. Knowledge of existing self-directedness capacity may be useful in designing and implementing holistic learner support programmes.
CONTRIBUTION/VALUE-ADD : The ALSDS may provide a reliable Afrocentric starting point for developing a measure for assessing the academic self-directedness of South African ODeLHE students.This research is based on a DCom postgraduate study
conducted by the author J.-A. Botha, in 2018 at the University
of South Africa that was funded through an internal bursary
by University of South Africa (Unisa) for postgraduate

Picture book trought the eyes of the children
No full textKroz temu „Slikovnica očima djeteta“ u uvodnom dijelu sam objasnila što je slikovnica i nabrojala neke njene definicije. Stoga možemo reći da postoje brojne definicije slikovnice i ne možemo reći ni za jednu da je pogrešna.
Prva slikovnica se pojavljuje u 17.st pod imenom Orbis sensualium pictus autora J.,A. Komensky, a u Hrvatskoj se smatra prvom slikovnicom Dječja čitanka o zdravlju autora Vladimira Kirina koja je izdana 1927.godine. Kratkim pogledom kroz povijest primjećujemo da se slikovnica u svijetu pojavljuje puno ranije nego u Hrvatskoj.
Slikovnica kao prva knjiga koju dijete primi u ruke ima brojne funkcije koje se prilagođavaju potrebama djeteta. Neke od njih su informacijsko – odgojna, spoznajna, iskustvena, estetska i najbitnije zabavna. Nije svaka slikovnica kvalitetna prema tome pri odabiru bi trebalo obratiti pažnju na: materijal, format, oblik, primjerenost dobi djeteta, tekst, format, ilustracije…
Dijete odrasta uz slikovnicu i ona ima veliku ulogu u razvoju govora, čitanja i pisanja, a uz sve to ima i jednu jako bitnu ulogu, a to je odgoj.
Slikovnica je često i poticaj za aktivnost. Kroz radove djece približila sam doživljaj djece nakon pročitane slikovnice. Odnosno djeca su nacrtala slikovnicu svojima očima. Svaki rad je jedinstven, izražen sa puno kreativnosti i mašte pa možemo reći da je slikovnica prozor u unutarnji svijet dječje mašte koji je nama često nedostupan.Through the theme "picture book trought the eyes of a child" in the first part I explained what is picture book and reeled off some of definition. We concluded that there are many definitions of a picture book, and we can't say that some of these is wrong. The first picture book appears in 17.st called Orbis pictus sensualium author J., A. Komensky, in Croatia is considered to be the first picture book „Children reading book on health“ by Vladimir Kirin, which was issued in 1927. Through the history we see that the picture book in the world appears much earlier than in Croatia.
The picture book as the first book that a child receives in the hands have a lot of functions that adapt to the needs of the child. Some of them are informational - educational, cognitive, experiential, aesthetic and most important fun. Not every picture book is quality, when we choose picture book we should pay attention to: material, size, shape, appropriateness of the child's age, text, format, illustrations ...
A child grow up with a picture book and it has a great role in the development of speech, reading and writing, and very important role is education.
The picture book is often the impetus for action. Trought the work of children I approached experience of children after I read picture book. In fact children are draw picture book trought their eyes. Each work is unique, pronounced with a lot of creativity and imagination so we can say that the picture book is window into the inner world of children's imagination, which is often unavailable to us
