高考评价体系确立核心价值、学科素养、关键能力、必备知识为考查内容,地理课程标准提出建立基于地理学科核心素养发展的学习评价体系。综合思维、区域认知是地理学科的基本思想方法,与人地协调观、地理实践力构成相互联系的有机整体。基于综合思维素养设计的试题有利于培养学生从整体的角度,全面、系统、动态地分析和认识地理环境;基于区域认知素养设计的试题有利于培养学生从区域的角度,分析和认识地理环境,并从多角度认识地理环境与人类活动的关系。 相似文献

高中地理新课程的基本理念之一是培养未来公民必备的地理素养,其中包括必备的地理知识和一定的地理学习能力。地图作为地理学科的第二语言,蕴涵着丰富的地理信息,是地理学科特有的信息综合载体和教学工具。对于地理教学而言,鉴于地图在地理教学中的特殊地位,教师更应着力培养学生的地图学习能力,逐步做到＂观其‘图’而知其‘地’,知其‘地’而求其‘理’”。 相似文献

本文以沪教版高中必修《地理1》第四单元“陆地环境”中的“土壤”一课为例,探索高中地理教师如何通过科学设计和有效组织地理实验来激活课堂,让学生在具身体验中主动获得新知、提升实践力素养,并以此为契机深入思考在“双新”背景下,高中地理教师如何通过革新教学理念和改进教学方法,以切实帮助学生提升地理学科核心素养。 相似文献

人地协调观、综合思维、区域认知和地理实践力是地理学科四大核心素养,是考试评价的依据。地理学科核心素养培养是地理课堂教学设计的灵魂。怎样把高度凝练的核心素养植根于课堂教学并将其内化,就成为中学教学研究的重要课题。本节课的设计旨在寻找学科核心素养培养与教学实践相结合的最优模式。首先根据核心素养内涵重组课程内容,兼顾学生基础,调动不同层次的学生参与整个教学过程,通过基础梳理、深化整合、命题探究、质疑反馈、精讲点拨、提能演练六大环节,层层递进,步步深入。 相似文献

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

We examine the sequence of changes in the structure of the geosystems of the Primorsky Range (Baikal region) for the last 6000 years, based on a continuous recording of fluctuations of the vegetation reconstructed from spore-pollen complexes of a high peat bog. We determined the chronological timeframe of paleogeographical events. The study showed that there occurred a radical structure transformation of the geosystems in the mid-late Holocene, along with a recurrence of similar landscape transformations caused by the instability of natural conditions. 相似文献

Summary. It is known that flow in the mantle can produce preferred orientation in olivine crystals with seismic anisotropy as a consequence. Flow in the subcrustal lithosphere is unlikely because of the high viscosity. Lenses of high temperature and low-viscosity ( anomalous mantle ) are located under the crust in many tectonically active regions, and viscous flow can easily arise in such material resulting in seismic anisotropy. After cooling, such anomalous mantle acquires high viscosity and becomes incorporated into the lithospheric layer preserving the anisotropy produced by the flows which existed previously. The interaction of the stresses with cracks in the upper crust can be one of the causes of anisotropy in this layer. 相似文献

我国北方东起黑龙江省嫩江地区, 吉林白城地区及辽宁西部, 包括内蒙兴安盟东南、哲里木、昭乌达、锡林郭勒、乌兰察布、伊克昭等盟的大部地区, 直至河北坝上、陕西榆林北部约26.7万平方公里的幅员范围内, 由于自然条件的特殊性(地表组成物质质地松散、沙粒成分比重很大及气候干旱、多大风, 且年内季风与周期性干旱相吻合), 加上人类不合理开发活动的影响, 成为我国目前沙漠化发展最活跃的地区, 其沙漠化土地近16.5万平方公里, 占全区总面积的61.5%。该地区有较长的经济开发史, 农、牧业相互影响, 交错分布的情况, 在历史上业已形成。据粗略统计, 该区范围内, 有旱作耕地近5, 000万亩, 多以传统的粗放的撂荒种植制进行经营, 长年遭受不同程度的风沙危害, 属于生产水平较为低下的农田类型。这些农田急待整治, 以便提高生产力。由于本区年均降水量在350-450毫米之间, 客观上具有发展旱作农业的可能性。如能合理经营、科学利用其自然资源, 将可能发展成为农、牧业结合的发达地区。从而对我国北方地区农业发展起促进作用。为了深化对沙漠化农田的认识, 揭示其生态失调的实质, 本文将就生态系统观点对其进行分析以寻求有效的整治沙漠化农田的途径。 相似文献

Summary. Previous geomagnetic measurements in the Rhinegraben have led us to assume that the responsible currents have the properties of direct currents and that they all flow in the sediments filling the graben. In order to verify these conclusions, we have performed measurements in a mine at a depth of 650 m. By comparing the field simultaneously recorded at the surface, in the mine and at the reference station, it is possible to deduce that the anomalous currents have the above mentioned properties. 相似文献

城市化的开发区模式研究 总被引：14，自引：1，他引：13
我国许多城市通过开发区建设,在短时间内完成了产业和人口的集聚,实现了城市地域空间和人口规模的跳跃性增长和产业结构的转型。由于在这种城市空间增长过程中,开发区建设起了决定作用,因此,这种以开发区带动整个地区城市化的方式可称为"开发区模式"。开发区驱动城市化的机制表现在开发区自身区域的城市化和开发区带动周围农村地区城市化两个层面,并具有快速跳跃性、外驱性和不稳定性、人为性、经济增长模式的单一性和基础设施建设的高标准性等特征。针对开发区建设中出现的问题,提出了促进其健康发展的建议。 相似文献

Field observations showed that the characteristics of chemical composition of waters and the development of plankton algae in the lakes within the delta of the Selenga river are determined by their flowage. The most open Lake Nekipelovskoe communicates with the Selenga outlets throughout a year, and Lake Zavernyaikha only at the period of an open channel. Lake Semenovskoe and Lake Khlystov Zaton are located in the islands and are isolated from the outlets. According to composition of main ions, the lakes under investigation refer to the hydrocarbonate class, the calcium group. The sum of ions in the water of Lake Nekipelovskoe approaches the one in the Selenga (86?221 mg/dm3), and the highest sums of ions were recorded in the wintertime in the lakes isolated from the outlets (446?743 mg/dm3). The lakes of the delta are characterized by a high trophicity. The maximum concentrations of total phosphorus in Lake Nekipelovskoe and Lake Zavernyaikha were 68 and 122 μg mg/dm3, and in Lake Semenovskoe and Lake Khlystov Zaton ?0.8 and ?0.63 μg mg/dm3, respectively. The most intense development of algae is observed in Lake Zavernyaikha, which is due to the high population of Baikal endemics. Lake Zavernyaikha showed a close negative correlation between the concentration of NO 3 ? , mineral phosphorus and phytoplankton biomass; the correlation coefficient was ?0.8 and ?0.63, respectively. The lakes exhibited increased contents readily hydrolysable organic matter, and a decrease in dissolved oxygen concentration in winter; hydrogen sulfide was repeatedly recorded in Lake Khlystov Zaton. The water quality in the lakes during the springtime varies from “quite clean” to “weakly polluted”; at low-water periods, especially in winters, it can drop to the category of “exceedingly dirty”. The water quality of the Selenga can be influenced by the lakes during spring floods when material accumulated during the wintertime is transported to the river outlets and further to Lake Baikal. 相似文献
