Students’ Acceptance On Educational Video Sharing Sit: A Proposed Research Model

Video sharing site is becoming increasingly popular and is used as a platform for video-based learning and teaching. In line with the development of new media technologies nowadays, learning through video sharing sites has become a choice of preference amongst students to get access to learning materials in the form of videos such as screencast tutorials, video presentations, recordings of learning video, animations and so forth. However, the existence of video sharing sites that have a social media characteristic in them is negatively affecting the students' learning performance. Thus, a provision of video sharing site with a more formal educational characteristic should be established in order to facilitate a safer learning environment. This study was conducted to analyse the acceptance of students towards educational video sharing sites. By using Technology Acceptance Model (TAM) as the basic model for this study, the original attributes in TAM model such as perceived usefulness and perceived ease of use were put to the test in order to determine their effects on attitudes and intentions of the students to use educational video sharing sites. In addition to that, TAM model was also expanded by adding other factors such as psychological factors (enjoyment and motivation), social factors (social influence and subjective norm), technological factors (system performance and system accessibility) and organisational factors (facilitating condition and technical support). This conceptual paper was prepared to tested on how they affect students' acceptance towards educational video sharing sit

EFFECTS OF SEGMENTATION OF INSTRUCTIONAL ANIMATION IN FACILITATING LEARNING

The aim of this study was to investigate the effects of segmented-animation, playpause- animation and continuous-animation in facilitating learning of low prior knowledge learners. A courseware prototype entitled Transmission Media was developed for the research purpose. The courseware contains nine animations on various topics in Transmission Media. Pre-test and post-test experimental design was employed on three different groups respectively. The data collected were analyzed statistically by using one-way between-groups ANOVA with post-hoc comparisons. Apparently, the result suggests that segmented-animation was significantly more effective than play-pause-animation and continuous-animation in enhancing students’ learning performance. The result indicates that segmented-animation was beneficial for students in conducting adequate cognitive processes of the information depicted in the animation. Furthermore, the result shows that allowing students to decide the segmentation in play-pause-animation condition does not necessarily promotes better learning. This was due to low prior knowledge students’ inability in deciding the appropriate stop points in animation and/or play-pause-replay button design that might causes split attention effect resulting extraneous cognitive load throughout the learning process

Dual-stage gain-clamped erbium-doped fiber amplifier with fiber Bragg grating

We demonstrate a dual-stage gain-clamped erbiumdoped fiber amplifier. The first-stage amplifier consists of a short length of erbium-doped fiber to produce low noise figures. The second-stage is constructed from a counter-propagating ringlaser, in which the signals and the lasing wavelength propagate in the opposite direction. The lasing wavelength is selected via a reflective-type of fiber Bragg grating. The gain-clamping mechanism can be adjusted by either changing the fiber Bragg grating reflectivity or center wavelength. The noise figure penalty is about 1.5 dB for the gain-clamping value from 11 dB to 20.5 dB. (© 2008 by Astro Ltd., Published exclusively by WILEY-VCH Verlag GmbH & Co. KGaA

Brillouin–Raman comb fiber laser with cooperative Rayleigh scattering in a linear cavity

We demonstrate a multiple-wavelength Brillouin comb laser with cooperative Rayleigh scattering that uses Raman amplification in dispersion-compensating fiber. The laser resonator is a linear cavity formed by reflector at each end of the dispersion-compensating fiber to improve the reflectivity of the Brillouin Stokes comb. Multiple Brillouin Stokes generation has been improved in terms of optical signal-to-noise ratio and power-level fluctuation between neighboring channels. Furthermore, the linewidth of the Brillouin Stokes is uniform within the laser output bandwidth
