Gapminder is a free and easy to use software for visualising real‐world data in multiple dimensions. The simple format of the Cartesian coordinate system is used in a dynamic and interactive way to convey a great deal of information. This tool can be readily used to arouse students' natural curiosity regarding world events and to increase the motivation to understand statistics. 相似文献

As well as maintaining the central role of literature, the new Australian Curriculum: English emphasises the multimodal nature of literacy and requires students in primary and secondary schools to develop explicit knowledge about visual and verbal grammar as a resource for text interpretation and text creation. This study investigated the use of visual grammatics in interpreting picture books by students across Years Four, Five, Seven and Ten following an intensive professional learning programme undertaken by their teachers. A proposed framework describes variation in students' interpretive stance from tactical to diegetic to semiotic. Levels of student semiotic understanding are differentiated and differences between students' oral and written interpretations are discussed in relation the need for explicit teaching of written interpretive responses to multimodal literary texts, drawing on an articulated visual and verbal grammatics appropriate to the teaching of English in primary and secondary schools. 相似文献

This study set out to examine the implementation of a video blog (vlog) project in an English for Specific Purposes (ESP) course that aimed to increase students' opportunities to use the target language. Specifically, it explored students' perceptions towards vlogs and analysed the advantages and disadvantages of vlogs as identified by the students. Data sources included an attitude survey, an open‐ended questionnaire, student interviews, written peer feedback, video clips in vlogs and reflective journals. The results indicated that firstly, the students favourably perceived the vlog project because vlogs not only helped them organise and reflect on their learning products, but also allowed them to archive their learning processes. Second, they reported a number of advantages associated with vlogging, such as visual representation, relief from time constraints, self‐evaluation, professional development, wider audience, peer learning and technical capability. Third, in the opinion of the students, the challenges compromising the effectiveness of the vlog project involved technical difficulties, affective interferences, weak linkage to real‐time communication and time issues. In light of these findings, the researcher proposes two pedagogical implications for ESP instructional practices. 相似文献

This study examines children’s strategies when scanning a document to answer a specific question. More specifically, we wanted to know whether they make use of organizers (i.e., headings) when searching and whether strategic search is related to their knowledge of reading strategies. Twenty-six French fifth graders were asked to search single-page documents presented on the screen of an eye tracker in order to respond to questions requiring the location of information in either a single paragraph (Location questions) or multiple paragraphs (Comparison questions). Location questions were easier and faster to answer than Comparison questions. The presence of headers led to more selective reading strategies but did not significantly speed up the search. Strong individual differences were observed in children’s scanning strategies: Some systematically fixated headers, whereas others did not. These differences were not significantly related to the participants’ decoding or comprehension skills but rather to their knowledge of reading strategies. 相似文献

Exhaustive exercise is associated with a persistent sensation of weakness and sometimes nausea suggesting abdominal vagal activity. We measured plasma indices of sympathoadrenal (adrenaline, noradrenaline, dopamine) and vagal (pancreatic polypeptide) activity before, during and after submaximal and maximal exercise in healthy young subjects. Plasma adrenaline, noradrenaline and dopamine increased to 8.5 (range 7.4–40.5), 48.0 (32.3–100.5) and 1.8 (1.2–6.6) nmol l–1 respectively (n = 5), during maximal exercise and decreased towards control values within 15 min of rest. Pancreatic polypeptide (n = 10) increased only during maximal exercise and reached its highest value, 48 (21–145) pmol l–1, after exertion. The results conform to an increase in sympathetic activity during exercise and a persistent vagal activity after intense exercise which could contribute to the sensation of weakness. 相似文献
