Humanoid robots in higher education: Evaluating the acceptance of Pepper in the context of an academic writing course using the UTAUT     

Josef Guggemos  Sabine Seufert  Stefan Sonderegger 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(5):1864-1883

This study investigates the acceptance of social robots by higher education students in the social sciences. Pepper, a humanoid social robot from SoftBank Robotics, provided a sample of its capabilities during a first semester, large-scale, university course, “Introduction to academic writing.”From this course, 462 freshmen participated in our survey. The unified theory of acceptance and use of technology (UTAUT) acts as the conceptual framework, and partial least squares structural equation modelling (PLS-SEM) as the method for data analysis. The four perceived characteristics—trustworthiness, adaptiveness, social presence and appearance—all predict the intention to use the robot for learning purposes; anxiety regarding making mistakes in handling the robot and about privacy issues are not significant predictors. An importance-performance map analysis indicated adaptiveness as the robot’s most important characteristic for predicting student behavioural intention. Overall, however, the study shows that students do not have the intention to rely on social robots for learning purposes at the current level of state-of-the-art technology: behavioural intention reaches only 36.6% of the theoretical maximum.  相似文献   

Determination of the centre of mass kinematics in alpine skiing using differential global navigation satellite systems     

Matthias Gilgien  Jörg Spörri  Julien Chardonnens  Josef Kröll  Philippe Limpach  Erich Müller 《Journal of sports sciences》2015,33(9):960-969

In the sport of alpine skiing, knowledge about the centre of mass (CoM) kinematics (i.e. position, velocity and acceleration) is essential to better understand both performance and injury. This study proposes a global navigation satellite system (GNSS)-based method to measure CoM kinematics without restriction of capture volume and with reasonable set-up and processing requirements. It combines the GNSS antenna position, terrain data and the accelerations acting on the skier in order to approximate the CoM location, velocity and acceleration. The validity of the method was assessed against a reference system (video-based 3D kinematics) over 12 turn cycles on a giant slalom skiing course. The mean (± s) position, velocity and acceleration differences between the CoM obtained from the GNSS and the reference system were 9 ± 12 cm, 0.08 ± 0.19 m · s^-1 and 0.22 ± 1.28 m · s^-2, respectively. The velocity and acceleration differences obtained were smaller than typical differences between the measures of several skiers on the same course observed in the literature, while the position differences were slightly larger than its discriminative meaningful change. The proposed method can therefore be interpreted to be technically valid and adequate for a variety of biomechanical research questions in the field of alpine skiing with certain limitations regarding position.  相似文献   

Teaching for analogical transfer as a means of improving problem-solving,thinking and learning     

Karl Josef Klauer 《Instructional Science》1989,18(3):179-192

Analogical transfer is transfer of a basic structure acquired through one or more instances to another instance. A basic structure like this is sometimes called a paradigm. Paradigmatic teaching, i.e. teaching for analogical transfer, requires the teaching of a basic structure by appropriate exemplars as well as the teaching of its application in various fields and contexts. This is demonstrated using research on teaching for problem-solving, inductive thinking, and learning-to-leam.Invited paper presented at the joint meeting of the Dutch Research Association on Instructional Processes (OTG), the German Division for Empirical Educational Research (AEPF) of the German Educational Association and the Division for Educational Psychology (FPP) of the German Psychological Association on April 23–25, 1989, at the University of Twente, The Netherlands.  相似文献   

Smoking, discount rates, and returns to education     

Josef Fersterer  Rudolf Winter-Ebmer   《Economics of Education Review》2003,22(6):561-566

Individual time preference determines schooling enrolment. Moreover, smoking behavior in early ages has been shown to be highly related to time preference rates. Insofar as discount rates are uncorrelated to ability, predicting school enrolment by discount rates can get rid of the ability bias in an earnings regression. Accordingly, we use smoking at age 16 as an instrument for schooling. Doing this for Austrian cross-sectional data, we find no evidence of ability bias in a simple earnings regression; the results are more mixed if family background is also included.  相似文献   

Biomechanical pole and leg characteristics during uphill diagonal roller skiing     

Stefan Josef Lindinger  Caroline Göpfert  Thomas Stöggl  Erich Müller  Hans-Christer Holmberg 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(4):318-333

Diagonal skiing as a major classical technique has hardly been investigated over the last two decades, although technique and racing velocities have developed substantially. The aims of the present study were to 1) analyse pole and leg kinetics and kinematics during submaximal uphill diagonal roller skiing and 2) identify biomechanical factors related to performance. Twelve elite skiers performed a time to exhaustion (performance) test on a treadmill. Joint kinematics and pole/plantar forces were recorded separately during diagonal roller skiing (9°; 11 km/h). Performance was correlated to cycle length (r = 0.77; P < 0.05), relative leg swing (r = 0.71), and gliding time (r = 0.74), hip flexion range of motion (ROM) during swing (r = 0.73) and knee extension ROM during gliding (r = 0.71). Push-off demonstrated performance correlations for impulse of leg force (r = 0.84), relative duration (r = ? 0.76) and knee flexion (r = 0.73) and extension ROM (r = 0.74). Relative time to peak pole force was associated with performance (r = 0.73). In summary, diagonal roller skiing performance was linked to 1) longer cycle length, 2) greater impulse of force during a shorter push-off with larger flexion/extension ROMs in leg joints, 3) longer leg swing, and 4) later peak pole force, demonstrating the major key characteristics to be emphasised in training.  相似文献   

On the effects of training inductive reasoning: How far does it transfer and how long do the effects persist?     

Welko Tomic  Karl Josef Klauer 《European Journal of Psychology of Education - EJPE》1996,11(3):283-299

Using the same program, two training experiments have been conducted in a Dutch and in a German elementary school. The common expectation was that training in inductive reasoning would transfer both on intelligence tests measuring inductive reasoning and on math performance. Furthermore, it was expected that the training effects would persist for at least some months after training had ended. In experiment 1 (N=34), a rather short training period turned out to be effective with respect to the intelligence test performance but not with respect to math performance. In experiment 2 (N=23), the amount of training in inductive reasoning was systematically varied. It could be shown that transfer on intelligence test as well as on math performance was linearly dependent on the amount of prior training. The training effects were found to persist between four and nine months after training.  相似文献   

STEERING PATTERNS IN THE AUSTRIAN UNIVERSITY SYSTEM     

Josef Langer 《Higher Education in Europe》1992,17(3):3-14

Inspired by Burton Clark's “triangle of coor‐dination” whereby a university is steered according to its relationship to “state authority”, the “academic oligarchy”, and the “market”, the author analyses the debate going on in Austrian higher education circles today about the proper way for the universities of the country to be steered. The general proposal is to supersede the University Organization Act of 1975, which had really been a reformulation of the traditional ministerial bureaucratic centralism typical of Austrian university governance, in favour of market‐oriented and decentralized approaches with many of the functions of the Ministry of Science and Research to be handed over to a buffer organization to be created. The chances are, however, that fundamentally very little of current practice will be changed because of the strength of set patterns and because of the inner contradictions within the principal reform proposals.  相似文献
