The Utility and Organization of a College Field Course: Examining National Park Management

Abstract

This article reviews the benefits of field-based instruction, particularly as it complements traditional classroom learning. It suggests that direct observation and hands-on learning associated with field-based instruction raise students' interest level and improve their understanding and long-term retention of targeted concepts. In addition, planning, implementation, and evaluation strategies are provided and recommendations are outlined for instructors interested in organizing or improving a field course at their learning institution. The park management field course offered between spring and summer semesters at Oklahoma State University provides an example of the major components of a successful field course.     

The Challenges and Rewards of Introducing Field Trips Into a Large Introductory Geography Class

Fieldwork is an essential component of undergraduate geographic education, but with growing enrollment and limited resources few first-year instructors incorporate this activity in their courses. This article reports on the challenges of incorporating fieldwork into a large first-year course and the strategies adopted to respond to these challenges and the achieved learning benefits. Field trips were created to cater to approximately 120 students directly engaged in field activities, with each student submitting an individual written report. Through the field activities, students developed a better understanding of geography, a stronger class community, and a more positive relationship with instructional staff.

测绘地理信息类专业双语课程评价体系构建

中国高校"双一流"建设要求培养兼备专业能力与国际竞争力人才,而双语教学则是一条有效途径。以CIPP(context,input,process,product)课程评价模型为理论依据,根据测绘地理信息类专业双语教学的特点,从背景评估、输入评估、过程评估、成果评估4个方面构建了测绘地理信息类专业双语课程评价指标体系,为提高中国测绘地理信息类专业双语课程的教学质量提供理论基础。     

中国高尔夫球场时空演变、影响因素和扩散模式

利用空间分析和数理统计等方法探究了1984—2016年中国高尔夫球场数量时空演变、影响因素和扩散模式。结果表明：1）球场数量变化经历了低速增长期、稳定增长期、加速增长期和紧缩期；2）球场空间分布范围经历了扩张期和收缩期，向北、向西扩散较为明显；3）目前球场主要分布在经济发展水平较高且外向型经济突出的长三角、珠三角和环渤海地区；4）人均GDP、人口规模、区域开放程度、交通优势度、气候类型和土地资源稀缺性与球场空间分布均呈显著正相关，其中交通优势度相关系数最大；5）高尔夫球场空间扩散模式兼具接触性扩散和等级性扩散。     

Extracting drainage networks and their connectivity using LiDAR data

Policies, measures, and models geared towards flood prevention and managing surface waters benefit from high quality data on the presence and characteristics of drainage ditches. As a cost and labour effective alternative for acquiring such data through field surveys, we propose a method (a) to extract vector data representing ditch drainage networks based on local morphologic features derived from high resolution digital elevation models (DEM) and (b) to identify possible connections in the ditch network by calculating a probability of the connectivity using a logistic regression where the predictor variables are characteristics of the ditch centre lines or derived from the DEM. Using Light Detection and Ranging (LiDAR) derived DEMs with a 1 m resolution, the method was developed and tested for a mixed agricultural residential area in north‐eastern Belgium. The derived ditch segments had an error of omission of 8% and an error of commission of 5%. The original positional accuracy of the centre lines of the extracted ditches was 0.6 m and could be improved to 0.4 m by shifting each vertex to the position of the lowest LiDAR point located within a radius equal to the spatial resolution of the used DEM. About 69% of the false disconnections in the network were identified and corrected leading to a reduction of the unconnected parts of the ditch network by 71%. The extracted and connected network approximated the reference ditch network fairly well.

大四专业课学生本位教学模式探索——以3S为例

针对大四专业课教育中出现的学生到课率低、学习兴趣不高、学习效果较差等问题,剖析"大四现象",围绕如何增强专业课的吸引力,从教育的本质出发,提出采用突出"学生本位"与"过程考核"的教学改革思路。以河南理工大学地理信息系统专业的"3S集成技术"课程为例,在分析该课程特点的基础上,通过改革考试模式,设置专题汇报、引入基于微信问卷的学生自主评价体系等方式予以实施。教学实践表明,该方式学生易于接受,使学生的学习积极性得以显著提高、综合能力得到锻炼。
