Modelling pre-service teachers’ perceived usefulness of an ICT-based student-centred learning (SCL) curriculum: a Singapore study

The purpose of this study is to examine the factors that influence pre-service teachers’ perceived usefulness of an Information and Communication Technology (ICT) course that was conducted using the student-centred learning (SCL) approach. In this study, perceived usefulness was used as the dependent variable and perceived competence, course delivery, facilitating conditions and learning environment as independent variables. The results of this study showed that perceived competence and course delivery have direct effects on pre-service teachers’ perceived usefulness of the course, while learning environment and facilitating conditions affect perceived usefulness indirectly. Overall, the results support the hypothesis that the four selected variables in this study affect perceived usefulness and that the resulting model is an adequate fit to the observed relationships among the factors that influenced pre-service teachers’ perceived usefulness of an ICT course.     

Fostering of creativity within an imaginative curriculum in higher education

Psychology is frequently used as a foundation discipline in the training of adult educators because it addresses those questions which naturally emerge from an engagement with adult learning and teaching (Tennant, 1997). The professional context which forms the focus of this article is no different. By providing academic support for lecturers in a higher education institution in Ireland, there is a desire to develop a sustainable curriculum model whereby by working with them on designing and developing creative curricula in their various subject disciplines in the arts and sciences they, in turn, pass the benefits of this on to their students.     

Enhancing the Student Experiment Experience: Visible Scientific Inquiry Through a Virtual Chemistry Laboratory

Practical work is often noted as a core reason many students take on science in secondary schools (high schools). However, there are inherent difficulties associated with classroom practical work that militate against scientific inquiry, an approach espoused by many science educators. The use of interactive simulations to facilitate student inquiry has emerged as a complement to practical work. This study presents case studies of four science teachers using a virtual chemistry laboratory (VCL) with their students in an explicitly guided inquiry manner. Research tools included the use of the Inquiry Science Implementation Scale in a ‘talk-aloud’ manner, Reformed Teaching Observation Protocol for video observations, and teacher interviews. The findings suggest key aspects of practical work that hinder teachers in adequately supporting inquiry and highlight where a VCL can overcome many of these difficulties. The findings also indicate considerations in using the VCL in its own right.     

Written narratives of normal and learning disabled children

Writing samples of children in grades one through three were collected in two midwestern elementary schools using the Picture Story Language Test. Each story was scored for productivity, syntax, and level of abstraction. Results indicated that performance in all aspects of written language improved with age. A second study was conducted to compare the writing of normal children who were average readers in grades one through three with learning disabled children who were reading at comparable levels. The results indicated no significant differences in productivity but there were differences in syntax. Problems were noted particularly in morphology. Further observations indicated the learning disabled poor readers also had more problems with handwriting and spelling than average readers.     

Effects of cooperative learning and need for affiliation on performance,time on task,and satisfaction

The purpose of this study was to investigate the effect of cooperative learning and the need for affiliation on performance, time on task, and satisfaction. Subjects used either a cooperative or individual learning strategy while receiving information, examples, practice, and feedback from an instructional television lesson. Results indicated that subjects who worked cooperatively spent more time working on practice exercises and reported greater satisfaction than those who worked individually. In addition, results revealed an interaction between instructional method and the need for affiliation. Performance of subjects with a high need for affiliation who worked alone was lower than that of all other groups when subjects were asked to apply what they had learned from the lesson. Implications for employing cooperative groups in settings that were originally designed for individual learning are provided.     

Children's Transition Into Full-Time Schooling: Black/White Comparisons

The transition from “home child” to “school child” is an important social milestone and encompasses a life period that has not received as much attention as it may deserve. Poor black children, who are those with the most social interaction disabilities, seem particularly vulnerable in the early part of this transition. A further complication is that “summer learning” helps mainly well-off children, and blacks in the population-at-large are less likely to be well off than whites. Although schools do seem to be making up for the dearth of academic socialization resources in many young children's households, and in this sense are most beneficial for those who need them most, more work is needed on why schools are not filling the bill as well for the neediest blacks as they are for the neediest whites.     

A Comparison of High School Teachers’ Instructional Postures in Regular Classrooms and in Computing Environments

ABSTRACT

High school teachers' classroom behaviors were observed and compared with their behaviors in the computing environment to determine whether or not the computer might act as a catalyst to promote facilitative behavior in teachers. No significant difference was found in terms of increased facilitative behavior in computer classrooms. However, female teachers adopted more facilitative postures in the computing environment than did male teachers, and the teachers with the greatest number of years of experience in teaching with computers appeared to exhibit more directive postures in both the regular and computing setting than did teachers with fewer years of experience. Implications of this for teacher education are discussed.     

Yoga From the Mat Up: How words alight on bodies

Abstract

Yoga is a unique form of expert movement that promotes an increasingly subtle interpenetration of thought and movement. The mindful nature of its practice, even at expert levels, challenges the idea that thought and mind are inevitably disruptive to absorbed coping. Building on parallel phenomenological and ethnographic studies of skilful performance and embodied apprenticeship, we argue for the importance in yoga of mental access to embodied movement during skill execution by way of a case study of instruction and practice in two related traditions, Iyengar and Anusara. Sharing a pose repertoire, they are based on distinctive philosophical systems with different teaching styles and metaphoric structures. To address relations between pedagogy and practice in embodied expertise, and to investigate the reciprocal influences of embodiment and thought, we explore in detail the linguistically mediated learning context where practitioners work with yoga teachers. Here, the mind/body problem comes to practical life. We demonstrate the effects of words on bodies, as knowledge is literally incorporated. We show why interpersonal influence on our movement capacities is sometimes needed to enhance expertise. We theorize and identify ‘signature patterns of tension’ among practitioners. These patterns have four sources: ghost gestures, innate differences in bodily form, functional fusing, and signature patterns of affective experience, modulation and expression. These patterns of tension produce ‘silent zones’, cognitively impenetrable actions, functional fusing of a skilful, compensatory form, and signature patterns of pain and damage. We show how instruction can disrupt these silent zones, enhancing mental and physical flexibility.     

The use of the intensity gradient and average acceleration metrics to explore associations with BMI z-score in children

ABSTRACT

This study used the intensity gradient (IG) and average acceleration metrics to describe children’s activity profiles and explore associations with body mass index (BMI) z-score. Two hundred and forty-six children (n = 138 girls) aged 9.6 ± 1.4 years wore a wrist-mounted ActiGraph wGT3X-BT accelerometer for 7 days on their non-dominant wrist. Physical activity (PA) metrics captured included: the IG which describes the intensity distribution of accelerations across the 24 h monitoring period; average acceleration which provides a measure of the volume of activity; total moderate-to-vigorous PA (MVPA) and inactive time. Acceleration was averaged over 5s epochs. Finally, BMI z-score was calculated for each participant. Average acceleration was negatively associated with BMI z-score (p < 0.05) independent of age and gender but not IG. The IG was negatively associated with BMI z-score independent of potential correlates and average acceleration. Total MVPA was not associated with BMI-z score. The IG and average acceleration metrics may be used to explore the independent or cumulative effects of the volume and intensity distribution of activity upon measures of health and well-being in children to inform specific activity recommendations.     

Muscle activation,blood lactate,and perceived exertion responses to changing resistance training programming variables

Ratings of perceived exertion (RPE: 0–10) during resistance training with varying programming demands were examined. Blood lactate (BLa) and muscle activation (using surface electromyography: EMG) were measured as potential mediators of RPE responses. Participants performed three sets of single arm (preferred side) bicep curls at 70% of 1 repetition maximum over 4 trials: Trial (A) 3 sets?×?8 repetitions?×?120?s recovery between sets; (B) 3 sets?×?8 repetitions?×?240?s recovery; (C) 3 sets?×?maximum number of repetitions (MNR)?×?120?s recovery; (D) 3 sets?×?MNR?×?240?s recovery. Overall body (RPE-O) and active muscle (RPE-AM) perceptual responses were assessed following each set in each trial. Biceps brachii and brachioradialis muscle EMG was measured during each set for each trial. RPE-O and RPE-AM were not different between Trial A (3.5?±?1 and 6?±?1, respectively) and Trial B (3.5?±?1 and 5.5?±?1, respectively) (p?p?相似文献
