Blended learning (BL) is a popular e-Learning model in higher education that has the potential to take advantage of learning analytics (LA) to support student learning. This study utilized LA to investigate fourth-year undergraduates' (n = 157) use of self-regulated learning (SRL) within the online components of a previously unexamined BL discipline, Music Teacher Education. SRL behaviors were captured unobtrusively in real time through students' interaction with course materials in Moodle. Categorized by function: (1) activating—online access location, day-of-the-week, time-of-day; (2) sustaining—online frequency; and (3) structuring—online regularity and exam review patterns, all six SRL behaviors were revealed to have weak to moderate significant relationships with academic achievement. Results indicated access day-of-the-week and access frequency as the strongest predictors for student success. Findings regarding access regularity when viewed through results from previous SRL-LA research may suggest the importance of this SRL behavior for successful students within several BL discipline areas. In addition, the role of learning design (eg, flipped instruction) in potentially scaffolding students' choices toward specific SRL behaviors, was revealed as an important context for future researchers' consideration. 相似文献

A study of iron, zinc, copper and selenium concentration levels was carried out in three compartments namely, maternal serum (MS), colostrums and cord blood serum (CS) of healthy Indian mothers (n = 42) who delivered healthy normal neonates without any congenital anomalies at Bhabha Atomic Research Centre hospital, Mumbai. Fe, Zn, Cu in maternal serum, cord blood and colostrums were estimated by flame atomic absorption spectrometry while Se was determined by graphite furnace absorption spectrometry. It was seen that there was a significant difference in the level of trace elements in the three compartments. The average levels of Fe in the three compartments were 1,132 ± 519, 2,312 ± 789 and 1,183 ± 602 μg/L while Zn was 514 ± 149, 819 ± 224 and 7,148 ± 2,316 μg/L respectively. Mean Cu values were 1,614 ± 295, 301 ± 77 and 392 ± 174 μg/L respectively while Se values were 70 ± 15, 36 ± 10 and 23 ± 8 μg/L respectively. The results indicated a positive correlation of Fe and Zn concentrations in MS versus CS which were (r = 0.386), (r = 0.572) respectively and Fe levels in MS and colostrums (r = 0.235). A few inter element correlations were found within compartments. Zn and Se showed a negative correlation in both MS (r = −0.489) and colostrums (r = −0.258) while a positive inter correlation of Fe and Zn was seen in MS (r = 0.44) and in CS (r = 0.54). This study gave us an overview of the serum and colostrum values of mother and neonates in Indian population, data of which are scarce. 相似文献

As low income societies experience rapid aging of their populations, they face major challenges in developing educational policies to prepare their workforce for the future. We review modest efforts undertaken to assist colleagues in three societies: Mexico, China, and Jamaica. Graduate education in gerontology has an important opportunity to expand research, training, and service-learning programs in global aging. 相似文献

The purpose of this study is to examine the impact of perceived brand orientation, intercultural friendship, and university reputation on international students’ course satisfaction and continuance behavioral intention towards the higher education in Malaysia. A total of 348 questionnaires, administered on international students, were collected to empirically test the research model using partial least squares path modeling approach, a structural equation modeling technique for the assessment of measurement and structural model. The empirical results imply that perceived brand orientation and university reputation positively influence course satisfaction and course continuance behavioral intention, while intercultural friendships influences course continuance intention but not course satisfaction. The implications and limitations of research are discussed in the following sections. 相似文献

Along with the significant development of information and communication technologies (ICTSs), an incredible number of mobile applications have become available. Hence, the main purpose of the current study is to investigate the use and acceptance of the ‘Mobile Information System’ developed and implemented by University of Jordan, which Known as (Mobile Student Information System). Data were obtained from 275 undergraduate students of University of Jordan via questionnaire to test the ‘Mobile Services Acceptance Model’ using Structural Equation Model. The results reveal that user acceptance of mobile information system services is largely affected by trust, perceived security, perceived ease of use and perceived usefulness. Findings also show that context of applications is a strong motivational factor of perceived ease of use and perceived usefulness, which then significantly affects user intention to use mobile information system. While, the personal characteristics and features do not have effect on user intentions. Both theoretical and practical implications of the study’s findings are discussed. 相似文献

The rapid growth of embedded vision applications and accessibility in recent years has instigated a philosophical shift in algorithm and implementation design for artificial intelligence. With the popularization of high-definition video, the amount of data available to be processed has also increased substantially, posing massive computational and communication demands. Hardware acceleration through specialization has received renewed interest in recent years; such acceleration has generally been implemented using two chips, with the image signal processing (ISP) part being performed by a DSP, a GPU or an FPGA and the video content analytics (VCA) part being executed by a processor. GPUs consume a substantial amount of power; thus, it is challenging to deploy them in embedded environments. However, the new generation of SoC-FPGAs that are fabricated with both the microprocessor and FPGA on a single chip consumes less power and can be built into small systems, thereby offering an attractive platform for embedded applications. This study presents the hardware acceleration of a real-time adaptive background and foreground identification algorithm in a SoC, including the capture, processing and display stages. The algorithm can be performed in either 2D or 3D space. The proposed platform uses photometric invariant color, depth data and local binary patterns (LBPs) to distinguish background from foreground. The system uses minimal cell resources, an elastically pipelined architecture is used to absorb variations in processing time, and each pipeline stage is optimized to use the available FPGA primitives. Additionally, the communication-centric architecture used in this work simplifies the implementation of embedded vision algorithms. 相似文献
