Knowledge sharing behaviors in e-learning community: exploring the role of academic self-efficacy and sense of community
(ScienceDirect, 2016)
Bu araştırmanın amacı, e-öğrenme topluluğundaki üniversite öğrencilerinin, bilgi paylaşım davranışları (BPD), akademik öz-yeterlikleri (AÖ) ve topluluk hisleri (TH) arasındaki yapısal ilişkileri incelemektir. Araştırma, ...
Quasi harmonic Bézier approximation of minimal surfaces for finding forms of structural membranes
(Elsevier, 2015)
Numerical approximation of minimal surface is an important problem in form-finding of structural membranes. In this paper, we present a novel approach to construct minimal surface from a given boundary by quasi-harmonic ...
The impact of interactive environment and metacognitive support on academic achievement and transactional distance in online learning

Bu araştırmanın amacı, çevrimiçi öğrenmede etkileşim ortamının ve üstbilişsel desteğin akademik başarı ve işlemsel uzaklık üzerine etkisini belirlemektir. Araştırma, 2X2’lik faktöriyel desene göre tasarlanmış olup, nitel ...
Exploring the role of e-learning readiness on student satisfaction and motivation in flipped classroom
(Computers in Human Behavior, 2017)
Ters yüz sınıf modelinde, öğrenci doyum ve güdülenmesinde yaşanan azalma sık görülen sorunlar arasındadır. Bu sorunlar ters yüz sınıf modelinin verimliliğini azaltabilmektedir. Ters yüz sınıf modelinde öğrenci doyum ve ...
The gauss map and the third laplace-beltrami operator of the rotational hypersurface in 4-space
(2018)
We study and examine the rotational hypersurface and its Gauss map in Euclidean four-space E4 . We calculate the Gauss map, the mean curvature and the Gaussian curvature of the rotational hypersurface and obtain some ...
Generalized bour s theorem
(Kuwait Journal of Science, 2015)
We give the classical isometric minimal helicoidal and rotational surfaces using generalized Bour’s theorem in Euclidean 3-space. Furthermore, we investigate the minimality and have same Gauss map of the surfaces.

Crambe L. is a species of the Brassicaceae family. It is an important industrial oil plant with high erusic acid content.
The objective of this study was to develop an efficient micropropagation protocol for Crambe ...
Dini-type helicoidal hypersurfaces with timelike axis in minkowski 4-space E14
(Mathematics, 2019)
We consider Ulisse Dini-type helicoidal hypersurfaces with timelike axis in Minkowski 4-space E41 . Calculating the Gaussian and the mean curvatures of the hypersurfaces, we demonstrate some special symmetries for the ...
