Assessing the Higher National Diploma Chemical Engineering programme in Ghana: students’ perspective
Cyril D. Boateng Edem Cudjoe Bensah Julius C. Ahiekpor 《European Journal of Engineering Education》2012,37(2):205-215
Chemical engineers have played key roles in the growth of the chemical and allied industries in Ghana but indigenous industries that have traditionally been the domain of the informal sector need to be migrated to the formal sector through the entrepreneurship and innovation of chemical engineers. The Higher National Diploma Chemical Engineering programme is being migrated from a subject-based to a competency-based curriculum. This paper evaluates the programme from the point of view of students. Data were drawn from a survey conducted in the department and were analysed using SPSS. The survey involved administering questionnaires to students at all levels in the department. Analysis of the responses indicated that the majority of the students had decided to pursue chemical engineering due to the career opportunities available. Their knowledge of the programme learning outcomes was, however, poor. The study revealed that none of the students was interested in developing indigenous industries. 相似文献

The influence of teachers upon pupil performance has been acknowledged in other studies as setting in motion a ‘self‐fulfilling prophecy’. But this informal segregation of children into good and bad academic prospects is in part determined by the headteacher's beliefs about the pupils’ potential achievement during and after their school lives. By setting different levels of expectation throughout the school the headteacher may impose upon certain sets of children a diminished self‐concept. To a significant extent, therefore, the headteacher predetermines the child's developing image of himself not only as a pupil but as a person. 相似文献

The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players. 相似文献

Animated graphics are extensively used in multimedia instructions explaining how natural or artificial dynamic systems work.
As animation directly depicts spatial changes over time, it is legitimate to believe that animated graphics will improve comprehension
over static graphics. However, the research failed to find clear evidence in favour of animation. Animation may also be used
to promote interactions in computer-supported collaborative learning. In this setting as well, the empirical studies have
not confirmed the benefits that one could intuitively expect from the use of animation. One explanation is that multimedia,
including animated graphics, challenges human processing capacities, and in particular imposes a substantial working memory
load. We designed an experimental study involving three between-subjects factors: the type of multimedia instruction (with
static or animated graphics), the presence of snapshots of critical steps of the system (with or without snapshots) and the
learning setting (individual or collaborative). The findings indicate that animation was overall beneficial to retention,
while for transfer, only learners studying collaboratively benefited from animated over static graphics. Contrary to our expectations,
the snapshots were marginally beneficial to learners studying individually and significantly detrimental to learners studying
in dyads. The results are discussed within the multimedia comprehension framework in order to propose the conditions under
which animation can benefit to learning. 相似文献

Magnetic and inertial measurement units (MIMUs) may provide an accessible, three-dimensional, in-field alternative to laboratory-restricted marker-based motion capture. Existing upper limb MIMU models have predominantly been validated with low-velocity motion and their suitability for use with sport-based movements remains relatively untested. We propose a MIMU system approach to enable the estimation of anatomically meaningful and participant-specific elbow kinematics with considerations for use with cricket bowling. A novel standardised elbow reference posture of 90 degrees flexion and 0 deg pronation, and functional definition of elbow joint axes of rotation calibrated the MIMU method model before it was validated across three experiments: (1) simple elbow rotations with a mechanical linkage; (2) low-velocity elbow rotations in human participants; and (3) low-medium velocity sport-based movements in human participants. The proposed MIMU method demonstrated high elbow kinematic measurement agreement when compared with a criterion measure across all three conditions. However, during experiment 3, sensor components neared their measurement capacity and the MIMU method elbow flexion measurement variability increased. We conclude that the proposed MIMU method can estimate anatomically referenced, participant-specific joint angles, however, the hardware specifications of currently available systems may limit application in high-velocity/acceleration situations, preventing the measurement of cricket bowling in-field for now. 相似文献

This article describes the extraordinary expansion of higher education in Hong Kong which took place from around the mid-1980s to the mid-1990s. It considers the factors involved in this expansion with some reference to theories of policy development, and speculates on certain aspects of the situation after the 1997 handover to the People's Republic of China. 相似文献
