A Novel Whiteheadean Science Program for 14-16 Year Olds in England and Wales     

Michael Akeroyd 《Interchange》2007,38(2):167-173

A novel “Whiteheadean” science program was initiated in England and Wales in September 2006. Following a critical House of Commons report in 2002, the government altered the National Curriculum targets and thus forced the Examination Boards to alter their specifications in order to come in line. Assessment at GCSE level (i.e., the 14-16 year cohort) was criticised for: a) failing to inspire students to continue with science, b) discouraging students from thinking for themselves, c) neglecting contemporary science, d) lacking flexibility, and e) making practical work into a tedious and dull activity. The British government has insisted that all pupils in state funded schools must know the names of some modern scientists and their work. They must discuss some current scientific problems. History and philosophy of science is included under the topic heading “How Science Works.” In Chemistry these objectives have destroyed the traditional linear top-down sequential approach of teaching into an approach based more closely on Whiteheadean lines (cf., the ideas expressed in The Aims of Education, 1926, Chapters 1-3).  相似文献

Why some teachers easily learn to use a new virtual learning environment: a technology acceptance perspective     

Bart Rienties  Bas Giesbers  Simon Lygo-Baker  Hoi Wah Serena Ma  Roger Rees 《Interactive Learning Environments》2016,24(3):539-552

After a decade of virtual learning environments (VLEs) in higher education, many teachers still use only a minimum of its affordances. This study looked at how academic staff interacted with a new and unknown VLE in order to understand how technology acceptance and support materials influence (perceived and actual) task performance. In an experimental design, 36 participants were split into a control (online help) and experimental (instructor video) condition and completed five common teaching tasks in a new VLE. In contrast to most technology acceptance model research, this study found that perceived usefulness of the VLE was not related to (perceived) task performance. Perceived ease of use was related to intentions and actual behaviour in the VLE. Furthermore, no significant difference was found between the two conditions, although the experimental condition led to a (marginal) increase in time to complete the tasks.  相似文献
