Aesthetics of Web and Mobile Interfaces of a Learning Management System: A Comparative Analysis

Aesthetics of a Learning Management System (LMS) user interface can be a very powerful tool for supporting learning, yet it is the least considered issue in design. This embedded experimental study researches the differences in perceived aesthetics of web and mobile interfaces of an LMS and the opinions of students about the effect of these differences on their learning. The data was gathered from a total of 128 students of a public university. The data collection instruments where, (i) Visual Aesthetics of Websites Inventory (VisAWI) for collecting quantitative data, and (ii) individual interviews with a sample of 10 students completing the inventory. This study reveals that learning materials presented in mobile devices might need design methods specific for mobile interfaces and it might have a positive impact on student learning


Polystyrene-organoclay nanocomposites prepared by melt intercalation, in situ, and Masterbatch methods
Yılmazer, Ülkü; Ozden, G (Wiley, 2006-06-01)
In this study, polystyrene (PS)/montmorillonite nanocomposites were prepared by melt intercalation, in situ polymerization, and masterbatch methods. In the masterbatch method, as the first step, a high clay content composite of PS-organoclay (masterbatch) was prepared by in situ polymerization, and then the prepared masterbatch was diluted to desired compositions with commercial PS in a twin-screw extruder. The structure and mechanical properties of the nanocomposites were examined. X-ray diffraction (XRD) ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
Kok, FN; Wilkins, RM; Cain, RB; Arica, MY; Alaeddinoglu, G; Hasırcı, Vasıf Nejat (1999-09-01)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate the rate of release. The encapsulation efficiency was low (4.15-13.00%) due to the high water solubility of aldicarb. Release into aqueous media was quite rapid and almost complete within 24h. Initial stages of the release (60% of AS released) was investigated to determine the release mechan...
Silica embedded cobalt(0) nanoclusters: Efficient, stable and cost effective catalyst for hydrogen generation from the hydrolysis of ammonia borane
Metin, Onder; Dinc, Melek; Eren, Zeynep Seda; Özkar, Saim (2011-09-01)
Cobalt(0) nanoclusters embedded in silica (Co@SiO2) were prepared by a facile two-step procedure. In the first step, the hydrogenphosphate anion (HPO42-) stabilized cobalt(0) nanoclusters were in situ generated from the reduction of cobalt(II) chloride during the hydrolysis of sodium borohydride (NaBH4) in the presence of stabilizer. Next, HPO42- anion-stabilized cobalt(0) nanoclusters were embedded in silica formed by in situ hydrolysis and condensation of tetraethylorthosilicate added as ethanol solution....
Effects of fluorination and thermal shock on the photocatalytic activity of Bi2O3 nanopowders
Bouzıanı, Asmae; Park, Jongee; Öztürk, Abdullah (2021-10-05)
Fluorinated Bi2O3 (F-Bi2O3) nanopowder was prepared via fluorination followed by thermal shock of α-Bi2O3 nanopowder. The XRD, FTIR, SEM, and DRS characterization techniques were employed to investigate the effects of fluorine (F) insertion into the α-Bi2O3 host and the thermal shock from different temperatures. The crystal structure, optical and photocatalytic properties of the F-Bi2O3 nanopowders prepared were researched. The XRD results confirmed the substitution of O2- with F-. The FTIR results revealed...
Mechanical, thermal and rheological characterization of polystyrene/organoclay nanocomposites containing aliphatic elastomer modifiers
Dike, Ali Sinan; Yılmazer, Ülkü (IOP Publishing, 2020-01-01)
In this study, organoclay containing polystyrene (PS) based nanocomposites were prepared by extrusion in the presence of aliphatic elastomer modifiers. Three different types of aliphatic elastomeric materials and three different types of organoclays were used. Their effects on the morphology, and mechanical, thermal, and rheological properties of PS were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction (XRD), tensile and impact tests, different...
