采用生物学实验法,通过采血化验、检测血糖、血浆K 、Ca2 、Na 、血睾酮等8项血液生化指标的含量,分析军校学生机动训练中不同负荷的身体适应特点。结果显示,24h昼夜强行军对身体机能的影响最大;学生对长时间、低强度、低密度的徒步行军完全适应。认为,适度增加徒步行军的强度和密度,并科学补充水和无机盐,是今后机动训练中应注意的问题。 相似文献

An integrative framework for studying,designing and conceptualising interactivity in children's digital books 下载免费PDF全文
Natalia Kucirkova 《British Educational Research Journal》2017,43(6):1168-1185
In the past five years, there have been significant changes concerning the material and design properties of digital books, with an impact on children's enjoyment and learning from reading on screen. Despite the rapid advances in technology, research on children's digital books is disjointed. This is because of no consistent approach to the study of interactivity, an under‐theorised relationship between print and digital books, and a binary design focused on either learning or playful engagement with digital books. Drawing on the discourse reminiscent of digital game designers, some developers, scholars and professionals celebrate interactivity in digital books as a possibility to motivate and engage children in reading, while a body of experimental research documents the negative impact of interactivity on children's story comprehension and vocabulary learning. This paper presents an integrative framework based on a comprehensive literature review and a content review of the hundred most popular children's digital interactive books. The framework offers: (1) methodological guidance and a definition of interactivity based on five key categories; (2) theoretical guidance based on the third‐space theory; and (3) innovative design and evaluation models based on a ‘method assemblage’. As such, the integrative framework provides new tools and perspectives to advance the field of children's digital books. 相似文献

This paper proposes a design framework to support science education through blended learning, based on a participatory and interactive approach supported by ICT-based tools, called Science Learning Activities Model (SLAM). The development of this design framework started as a response to complex changes in society and education (e.g. high turnover rate of knowledge, changing labour market), which require a more creative response of learners to the world problems that surround them. Many of these challenges are related to science and it would be expected that students are attracted to science, however the contrary is the case. One of the origins of this disinterest can be found in the way science is taught. Therefore, after reviewing the relevant literature we propose the SLAM framework as a tool to aid the design of science courses with high motivational impact on students. The framework is concerned with the assumption that science learning activities should be applicable and relevant to contemporary life and transferable to ‘real-world’ situations. The design framework proposes three design dimensions: context, technology and pedagogy, and aims at integrating learning in formal and informal contexts through blended learning scenarios by using today’s flexible, interactive and immersive technologies (e.g. mobile, augmented reality, virtual reality). 相似文献
