Doing Independent Overseas Fieldwork 1: Practicalities and pitfalls

This article explores issues of scalability and sustainability in distance learning. The authors kept detailed records of time they spent teaching a course in geographic information science via the World Wide Web over a six-month period, during which class sizes averaged 49 students. The authors also surveyed students' satisfaction with the distance learning course through ratings and open-ended questions. Findings are compared with similar data collected a year earlier, when class sizes associated with the same distance learning course averaged 18 students. In response to the increase in average class size by a factor of 2.7, the authors' course-related workloads increased by a factor of about 2.5 (from 47.5 hours to 116.7 hours total). Analyses of student feedback suggest that student satisfaction with the course was high overall and suffered no significant decline as a result of increased instructional efficiency.     

Group Project Work and Student-centred Active Learning: two different experiences

This article compares two experiences of group-based student projects in a Geographical Information Systems (GIS) degree and in Geography degree modules. The two authors adopted group projects from similar motivations, and used available materials to guide them through this process. Subsequently, they have come to reflect on the experience and to examine the theoretical dimensions of such an approach in more detail. There seems to be a discrepancy between the literature, which emphasises a growing interest in the socio-educational value of group-based and active learning, and the concerns voiced by both students and academics regarding the practical implications of such approaches. Analysis of grades and questionnaires tends to support the literature and belie the criticisms, which the authors see as 'myths', possibly motivated by a defensive attitude to the whole learning process. The conclusions are that, if care is not taken in the design and execution of such projects, then the problems that may ensue can reinforce the 'myths'. However, if carefully and appropriately designed and managed, team-based learning is a valuable experience.     

Using the Internet to Support International Collaborations for Global Geography Education

This paper reports the results of a pilot study that evaluated a prototype instructional module designed to support international collaborative learning in the World Wide Web. The module, Migration, was tested at four higher education institu tions in the United States, Canada, and Australia. Students valued the opportunity to learn global geography by collaborating electronically in multinational teams, yet many students complained about confusing instructional procedures and uncooperative team members. The results of the module evaluation provide useful suggestions for managing pedagogical issues related to the process of online international collaborative learning.     

E-learning for Geography's Teaching and Learning Spaces

The authors embed their advocacy of educational technology in a consideration of contemporary pedagogy in geography. They provide examples of e-learning from a wide range of teaching and learning contexts. They promote the idea that considering best practice with reference to educational technology will increase the versatility of teaching geography in higher education. On the basis of reviewing the pedagogic options associated with e-learning using a variety of technologies, and their promotion of versatility in the use of e-learning approaches, they find and illustrate the new spaces that have become available to teachers and learners of geography.     

Are South African Geography education students ready for problem-based learning?

Problem-based learning (PBL) is one of the possible training strategies that could be more fully implemented in the South African formal education system. The intention to migrate from teacher-centred to learner-centred instructions in higher education institutions and schools makes PBL a plausible option. Geography education students might be exposed to PBL because their training implies the acquisition of abilities to solve real-world situations at various geographical scales. This paper explores the perception of second- and third-year students in a BEd programme in Potchefstroom, South Africa. The study uses a mixed-method research approach based on questionnaire application, students' learning journal entries and field notes. Findings from the study indicate that students show very positive perceptions of PBL as a training strategy for teaching and learning. A gender difference regarding general aspects of PBL, independent learning, workload, assessment rubrics and the different role-players in PBL indicates that female students hold more positive perceptions of the PBL experience. Overall, the results indicate that students with higher academic performances in most instances hold more positive perceptions of the PBL experience.     

Student perceptions of iPads as mobile learning devices for fieldwork

This paper reports findings from six field courses about student's perceptions of iPads as mobile learning devices for fieldwork. Data were collected through surveys and focus groups. The key findings suggest that the multi-tool nature of the iPads and their portability were the main strengths. Students had some concerns over the safety of the iPads in adverse weather and rugged environments, though most of these concerns were eliminated after using the devices with protective cases. Reduced connectivity was found to be one of the main challenges for mobile learning. Finally, students and practitioners views of why they used the mobile devices for fieldwork did not align.     

Transformative learning in community college human geography: a mixed methods study

ABSTRACT

The study explores the extent to which transformative learning occurs using quantitative and qualitative methods in a human geography course (N = 35) and explores student affect in relation to the learning environment. We used the eight-scale Transformative Learning Environments Survey (TLES) instrument for the quantitative analysis and an aligned analysis of student reflective work to capture the “voice” of the student as a qualitative approach that provided a rounded perspective of transformative learning. The TLES proved reliable where the sub-scale Alpha reliability ranged from 0.71 to 0.93 and a separate affect scale of Satisfaction was 0.95. The standardized regression coefficient between Satisfaction and the sub-scale of Student-Acting demonstrated the strongest positive association (0.27), followed closely by Disorienting Dilemma-Environment (0.24). The qualitative results supported the quantitative associations in most cases, but not all. The qualitative aspect to this present study offers a deeper look – beyond just statistical outcomes – using students’ own voices to explain their perspectives related to transformative learning.     

The silver screen

Abstract

Based in educational theory and with an interdisciplinary backdrop, this paper applies to economic geography thoughts and contributions pioneered in agricultural science by Professor Richard Bawden. Commonly held educational objectives are interpreted alongside three major teaching traditions. From this analysis, the potential relevance of experiential learning is examined in the light of paradigmatic shifts in economic geography and practical developments in tertiary milieu. The conclusion is that praxis‐based teaching deserves more attention than it has previously received.     

基于环境监测和机器学习的自动化洞窟保护管理方法

科学有效的石窟环境保护与管理策略对窟内文物的安全至关重要。利用麦积山两个单开口洞窟的环境监测数据,基于机器学习等数据科学技术,建立了一种自动化洞窟保护管理方法,可依据窟内外水汽的活动来实时判别窟门的活动。先根据监测数据遴选水汽活动的三个特征参数——趋势、数值和短时波动差异,再采用机器学习分类器识别窟门的长期开闭状态,最后通过离群值进一步诊断检测人员的瞬时出入情况。评估结果表明,在筛选出最优参数的情况下,支持向量机模型具有良好的综合识别准确率,其中窟门开闭状态达97.7%,瞬时出入活动检测达94.9%,满足自动化洞窟管理的需求。为未来的保护管理方案制订提供数据参考,并为预防性保护工作提供技术支持。
