First-year tertiary students' understandings of iron filing patterns around a magnet

This paper describes responses from 28 first-year university physics students to one question of a written test which was followed up by an interview. The study has two main research aims. Firstly, it characterises the conceptual structures of students regarding the phenomenon in question. As well as being interesting in their own right, these student understandings cast light on some broader issues regarding understanding of field representations. While students' understandings of circuit electricity are well described in the existing science education literature, their understandings of field phenomena are not. Secondly, it throws light on theoretical questions about the SOLO Taxonomy, which is the framework used to study the students' conceptual structures. Of particular interest is the nature of student thinking that marks transition from the Concrete Symbolic to the Formal SOLO mode in this area. Specializations: physics education, electricity and magnetism, conceptual structures, SOLO Taxonomy. Specializations: SOLO Taxonomy, conceptual structures, mathematics education.     

Observing preschool storytime practices in Aotearoa New Zealand's urban public libraries

This study explores how preschool storytimes in public libraries in Aotearoa New Zealand incorporate practices which have been identified as beneficial for children's early literacy skills. The results of observations of storytimes in four public library services are reported, focusing on whether they included activities that foster six key literacy skills: print motivation; phonological awareness; vocabulary; narrative skills; print awareness and print concepts; and letter awareness. The results indicate that the storytimes observed focused strongly on techniques to increase children's print motivation, and other skills, such as the development of letter awareness, did not feature as frequently. It is suggested that the librarians leading the sessions were wary of introducing more formal instructional elements into the storytimes because they felt it might detract from the main aim of the sessions, which was to encourage children to enjoy books and reading.     

Deep Dive into KBART

ABSTRACT

The Deep Dive into KBART preconference workshop provided a comprehensive overview of the National Information Standards Organization Knowledge Bases and Related Tools (KBART) Phase II Recommended Practice (http://www.niso.org/publications/rp/rp-9–2014/). The workshop was divided into four sections. The first provided an overview of the background, purpose, and value of KBART to all members of the information supply chain. The next section focused on the basic guidelines for effective exchange of metadata with knowledgebases, including method of exchange, data format, file naming conventions, and frequency of exchange. The remaining two sections of the workshop addressed the correct use of KBART data fields, first in relation to serials and then to monographs. Through classroom instruction, interactive quizzes, and hands-on exercises, the workshop provided in-depth coverage of all KBART data elements, with special focus on many of the most frequently asked questions about the recommended practice.     

Pupils’ attitudes towards school science as they transfer from an ICT-rich primary school to a secondary school with fewer ICT resources: Does ICT matter?

The first part of this study was carried out in a primary school in a rural part of Wales in the United Kingdom. All classrooms were equipped with interactive whiteboards (IWBs) linked to a teacher’s computer and six PCs for pupil use. Teaching through ICT was the prevalent culture in the school. Thirty year six pupils [aged 10–11 years] were selected at random from the final year cohort and were interviewed to determine their views about school science and their views about the teaching methods employed. The pupils moved to a medium sized secondary school where the teachers were beginning to develop their ICT skills and the availability of the computers was limited. The group was re-interviewed after 3 months, once they had settled in to their new school, and were again asked their views about school science and the way it was taught. While in the primary school, pupils expected to use ICT in every lesson, they enjoyed the way information was presented and they were interested in finding things out for themselves when given the opportunity. The lack of ICT in the secondary school caused some frustration, but this was mostly with the teaching of ICT, and the group remained predominantly enthusiastic about science. Those who were less keen on science indicated that it was a teacher factor rather than anything to do with the resources being used. In general the pupils particularly enjoyed the practical aspects of science lessons, something that they had not experienced in the primary school, which compensated for the relative lack of ICT in science teaching.     

Hemispheric laterality in music and math

Hemispheric laterality may be a useful concept in teaching, learning, training, and in understanding more about human development. To address this issue, a measure of hemispheric laterality was compared to musical and mathematical ability. The Human Information Processing Survey (HIPS) instrument, designed to measure hemispheric laterality, was administered to 101 participants who were then asked to provide a measure of their conceptual aptitude for mathematics and music. Scores were then compared through canonical correlation to test the hypothesis that perceived mathematical ability may be explained by left-brain hemisphere preference and musical by the right hemisphere. A relatively strong correlation was found between music ability and right-brain hemisphere preference. A relationship between math and left-brain hemisphere preference or integrated brain processing scores was found to be marginal. Ramifications to learning are discussed.     

Metricon 2.0关注安全度量

2007年IEEE在波士顿召开了Metricon2.0工作会议,同时进行的还有第十六届Usenix安全研讨会.与会人员被问到的首要问题是:"度量事关重大吗?"你可以想象,与会者对这一问题的直觉问答会是"yes",但是经过会议当天的一番激辩,支持这一回答的人数在数量上只是稍占上风.
