Facilitating active social presence and meaningful interactions in online learning     

Jared Keengwe  Emmanuel Adjei-Boateng  Watsatree Diteeyont 《Education and Information Technologies》2013,18(4):597-607

Online learning has minimized many barriers and constraints that are common in traditional learning environments. However, due to the absence of face-to-face contacts, students and instructors are usually faced with the lack of active social presence and meaningful interactions in online learning. This article explores a review of the literature on social presence and various types of interactions in online learning environments in the context of a class project. The findings suggest need for online instructors to explore effective ways to design and facilitate active social presence and meaningful interactions in online learning.  相似文献   

Observer based leader-following consensus of second-order multi-agent systems with nonuniform sampled position data     

Syed Ali Ajwad  Tomas Ménard  Emmanuel Moulay  Michael Defoort  Patrick Coirault 《Journal of The Franklin Institute》2019,356(16):10031-10057

This paper deals with the leader-following consensus problem of multi-agent systems with the consideration that each agent can only transmit its position state to the neighbors at irregular discrete sampling times. In the proposed algorithm, a continuous-discrete time observer is designed for the continuous estimation of both position and velocity from the discrete position information of the neighbors. These estimated states are then used for designing a continuous control law which solves the leader-following consensus problem. Moreover, the dynamics of the leader is not fixed and can be controlled through an external input. The stability analysis has been carried out by employing the Lyapunov approach which provides sufficient conditions to tune the parameters according to the maximum allowable sampling period. The developed algorithm has been simulated and then tested on an actual multi-robot system consisting of three differential drive wheeled robots. Both simulation and hardware results validate the effectiveness of the control algorithm.  相似文献   

Global references,local translation: adaptation of the Bologna Process degree structure and credit system at universities in Cameroon     

Elizabeth Agbor Eta  Emmanuel Yenshu Vubo 《Globalisation, Societies & Education》2016,14(4):492-512

This article uses temporal comparison and thematic analytical approaches to analyse text documents and interviews, examining the adaptation of the Bologna Process degree structure and credit system in two sub-systems of education in Cameroon: the Anglo-Saxon and the French systems. The central aim is to verify whether such adaptation has replaced, re-enforced or modified existing practices. Secondly, the article analyses the factors that have influenced this adaptation. The results highlight the idea that education systems may demonstrate a level of awareness about global practices, but these practices are interpreted in their local contexts; thus, policy-makers ‘think globally but act locally’.  相似文献

Effectiveness of an Intensive Learning Skills Course for University Students on Restricted Enrolment     

Emmanuel Manalo  Glenis Wong‐Toi  Marcus Henning 《高等教育研究与发展》1996,15(2):189-199

Prior to the commencement of the 1994 academic year, University of Auckland students who had failed one‐half or more of their papers in the previous year were invited to attend a four‐day intensive learning skills course conducted by the Student Learning Centre of the University. The course covered various topics such as effective time management and study organisation, preparing for and taking tests and exams, memory and concentration, and writing skills. A total of 74 students attended the course. After final examinations, the results of these students were analysed. As a group these students significantly improved on their previous year's pass rates. Furthermore, their pass rates were significantly better than those of a randomly selected group of students who were in a similar situation with regard to their previous year's academic performance, but who did not attend the course.  相似文献   

30 min of treadmill walking at self-selected speed does not increase gait variability in independent elderly     

Emmanuel S. Da Rocha  Marcos R. Kunzler  Maarten F. Bobbert  Jacques Duysens 《Journal of sports sciences》2018,36(11):1305-1311

Walking is one of the preferred exercises among elderly, but could a prolonged walking increase gait variability, a risk factor for a fall in the elderly? Here we determine whether 30 min of treadmill walking increases coefficient of variation of gait in elderly. Because gait responses to exercise depend on fitness level, we included 15 sedentary and 15 active elderly. Sedentary participants preferred a lower gait speed and made smaller steps than the actives. Step length coefficient of variation decreased ~16.9% by the end of the exercise in both the groups. Stride length coefficient of variation decreased ~9% after 10 minutes of walking, and sedentary elderly showed a slightly larger step width coefficient of variation (~2%) at 10 min than active elderly. Active elderly showed higher walk ratio (step length/cadence) than sedentary in all times of walking, but the times did not differ in both the groups. In conclusion, treadmill gait kinematics differ between sedentary and active elderly, but changes over time are similar in sedentary and active elderly. As a practical implication, 30 min of walking might be a good strategy of exercise for elderly, independently of the fitness level, because it did not increase variability in step and stride kinematics, which is considered a risk of fall in this population.  相似文献

Towards automated e-counselling system based on counsellors emotion perception     

Emmanuel Awuni Kolog  Calkin Suero Montero 《Education and Information Technologies》2018,23(2):911-933

Emotions are a core semantic component of human communication. Since counsellors are humans we assume that their own state of emotions could affect their intuitional effort when taking decisions concerning their clients. Therefore, the accuracy of detected emotions by counsellors could be doubtful. And this highlights the need for complementing the intuitional effort of counsellors by computational approach. Therefore, ascertaining the efficacy of computational algorithm, there is the need to benchmark with humans. In this paper, we explore empirically, the extent to which counsellors own emotional states influence their perception of emotions expressed in text. This influence is investigated through the level of agreement among counsellors when annotating emotions expressed in students’ personal life’s stories. The result shows strong intra-counsellor annotation agreement of emotions while inter-counsellors annotation agreement was low. Furthermore, the intra-annotation agreement of emotions was found to be strongly correlated to the counsellors’ self-reported emotions. We speculate, based on the findings, that the emotional state of counsellors influences their emotion perception while tracking emotions in text. Based on the results, we discuss the advantages of using an automated e-counselling system for emotion analysis.  相似文献

Abstract

The purpose of this study was to determine the effects of intensified physical education sessions on adolescents ages 11–16 years. They were divided into two experimental groups—high-intensity running group (HIRG) and high-intensity jumping group (HIJG)—and a control group (C). During the sessions, heart rate (HR) was monitored. There was no significant difference between mean HR for HIRG and HIJG, while the mean HR was significantly lower for C (p < .001). For both HIRG and HIJG, the mean HR was significantly higher for girls than for boys (p < .001). Our results suggested that these intensified physical education lessons require a high percentage of maximal HR in adolescents and can be used to improve aerobic fitness.  相似文献
