大概念视域下的高中地理生活化教学设计有助于建构和完善学生知识体系,提高学生认知水平,加强知识应用能力。本文以“水循环”一节为例,在大概念的统摄下,以具身理论为指引,构建“分布—整合—内生”的教学模式,突出地理学科紧密联系生活的重要性,助力学生地理核心素养的培养。 相似文献

当前的地理高考复习课以课程标准及“一核四层四翼”高考评价体系为实践指南,着力建构“地理课程思政”和“地理思想方法”融通的“两思”课堂,从而有效落实地理核心素养和实现立德树人目标。本文在“百年复兴梦,铁路新征程”高考专题复习课的教学实践中,尝试建构“体验—感悟—测评”为依托的“两思”课堂,通过结构化教学设计来实现“两思”的深度融合。 相似文献

The process of organic matter transformation into oil and gas is also a balance process of hydrocarbon transformation. This
article probes to distinguish the oil expulsion history from gas expulsion history based on the hydrocarbon generation, hydrocarbon
residual, and hydrocarbon expulsion processes of the source rocks. In this method, the first step is to study the hydrocarbon
expulsion rate by means of hydrocarbon generation potential method; the second step is to study the oil generation rate by
means of the heating–pressuring experiment method; the third step is to study the oil residual rate by means of the mathematical
method. The difference between the values of oil generation rate and oil residual rate is defined as the oil expulsion rate,
while that between the values of hydrocarbon expulsion rate and the gas expulsion rate is defined as the gas expulsion rate.
Then, combined with the geological parameters of source rocks, the oil and gas expulsion history can be obtained. This study
on Es1 Source rocks, Nanpu Sag, Bohai Bay Basin, China shows that the primary expulsion period of Es1 source rocks is Guantao–Minghuazhen period. 相似文献

Alan R. H. Baker 《The Professional geographer》2007,59(3):344-356
Although the term “historical geography” has been the subject of a sustained and critical debate, that of “geographical history” has not. Usage of the latter term has been variable and the epistemological status of geographical history has been ambiguous. An examination of the usage of the term “geographical history” during the past 100 years or so reveals both that it has been employed little but confusingly and that there have recently been calls for its wider adoption. Two key themes are identified in the literature: first, that of geographical history as the study of changing geographical distributions; and second, geographical history as the study of geographical (in the sense of physical environmental) influences in history. In theory it is possible to distinguish geography from history and historical geography from geographical history, but in practice it is often difficult to do so. Nonetheless, examining usage of the term matters as a contribution to the history of ideas, and identifying its common usages allows scholars to communicate with mutual understanding. 相似文献

中国沙漠科学的五十年 总被引：40，自引：20，他引：20
50多年来,在几代沙漠科技人员的不懈努力下,中国的沙漠科学从无到有,在从填补沙漠研究空白并取得长足进展的同时,沙漠化研究又以其创新性和系统性的理论进展,经济、社会和环境效益的实践成果,极大地充实了我国的沙漠科学,为我国北方地区国民经济建设和生态环境保护做出了突出的贡献,取得了包括国家科技进步特等奖在内的一大批科研成果和上百亿元的直接经济效益。过去20 a来,北方约有 10%的沙漠化土地得到治理,12%的沙漠化土地有所改善,局部地区出现"人进沙退"的新局面。已形成了以中国科学院和国家林业局等有关研究所为主体的国家级沙漠和沙漠化研究机构,汇集了一批优秀的沙漠和沙漠化科学家,创建了我国比较完整的沙漠和沙漠化科学及其研究体系,在风沙物理与沙漠环境、沙漠形成演变与全球变化、沙漠化过程及其防治、沙区资源环境与可持续发展、沙漠化遥感与信息系统综合研究等方面取得了重大进展,积累了丰富的研究资料和数据。在全国主要沙漠和沙漠化地区设有一批长期野外试验站(点),已为国家在有关沙漠开发利用和沙漠化防治方面的决策提供了大量的科研成果和理论依据。我国沙漠科学研究和实践所取得的辉煌成就,得到了政府、地方民众、科学界和国际社会的普遍认可。 相似文献
