Learning novel mathematical concepts in a computer-enriched environment     

Cyril Julie 《British journal of educational technology : journal of the Council for Educational Technology》1991,22(2):99-109

There is widespread belief that computers should be used for the teaching and learning of mathematics. Research indicates that computers are primarily used in mathematics classes: (1) to reinforce previously taught concepts, (2) to allow students to construct computer programs to simulate mathematical techniques known to the student and (3) to explore mathematical microworlds encompassing mathematical ideas and concepts normally known to the student. Furthermore, it is said that pre-service teachers should experience the learning of mathematical ideas and concepts of which they had no prior experience in environments in which computers are just one of the resources available for exploring and experimenting with these ideas and concepts. How should these learning environments be constructed so that pre-service teachers are sensitised to the value of doing mathematics in such environments? Is a student's understanding of novel mathematical concepts enhanced when s/he explores it in a computer-enriched environment? An experiment with pre-service teachers was carried out in a college of education for blacks in South Africa. This article describes the insights gained from this experiment.  相似文献

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

Daniel J. Hiscock  Brian Dawson  Cyril J. Donnelly  Peter Peeling 《European Journal of Sport Science》2016,16(5):536-544

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

EVALUATION OF TEACHING     

Cyril Selmes 《Assessment & Evaluation in Higher Education》1989,14(3):167-178

This paper attempts to ‘lay out’ as clearly as possible some of my preconceptions and assumptions about the evaluation of teaching. The main focus is on teaching in higher education but I hope the ideas may be applicable to teaching in general.

The main reason for this analysis was a feeling of dissatisfaction with many of the papers I had read, but the attempt to make my assumptions as explicit as possible was the result of trying to understand the process of bracketing — a process central to existential‐phenomenological psychology in which one attempts to take a ‘transcendental attitude'’ ‘ to the world rather than a ‘natural attitude’. Whilst my understanding of this process may be inadequate, even faulty, I think the process has helped me to clarify my ideas about both teaching and the evaluation of it.  相似文献   

Distance higher education for women in Saudi Arabia: Present and proposed     

Haya Saad Al Rawaf  Cyril Simmons 《Distance Education》1992,13(1):65-80

This paper describes the recent history of distance higher education in Saudi Arabia with particular reference to the education of women. It compares the contribution to external study for women of the General Presidency of Girls' Education (GPGE) with the introduction of intisab (a system which allows individuals to pursue higher education without attending lectures) in three universities founded for men. It records the growing numbers of women wishing to enter higher education and the withdrawal of intisab from two universities in Riyadh. It identifies the limitations placed on women's higher education as compared with men's and notes the generally conservative attitudes to the role of women found in Saudi Arabia. It oudines discussions over the last 15 years, concerning an Arab open university, which have yet to result in action. Finally, it reports a recent survey which reveals strong support for an open university for women in Saudi Arabia. Such an institution would gready increase access for women to higher education while, at the same time, be compatible with Islamic custom concerning the segregation of the sexes and a woman's primary role as wife and mother.  相似文献
