Abstract

The rise of AI tools has transformed the educational landscape in Singapore, offering unprecedented efficiency and access to information. This study examines the integration of AI in Geography classrooms, a subject where inquiry-based learning and sustainability education form the core. Interviews with four Geography teachers revealed that while AI supports content mastery, information retrieval, and initial ideation, it is less effective in fostering empathy, ethical reasoning, and emotional connections to sustainability topics. The reliance on AI to process data and present information as statistics can deprive students of opportunities to engage with the moral and affective dimensions of sustainability education, which are essential for fostering empathy and ethical reasoning. The findings underscore the importance of intentional, critical use of AI, guided by educators, to ensure that technological affordances complement rather than compromise learner-centered, context-rich sustainability education.

Abstract This article examines the impact of structured thinking anchors on Singapore students’ ability to respond effectively to data response questions (DRQs) in geography. Through a seven-week action research study using the OHLA (Overall, Highest, Lowest, Anomaly) thinking anchor with Secondary 1 Express (G3) and Normal (Academic) (G2) students in 2022, this research demonstrated significant […]

Abstract

This article examines the impact of structured thinking anchors on Singapore students’ ability to respond effectively to data response questions (DRQs) in geography. Through a seven-week action research study using the OHLA (Overall, Highest, Lowest, Anomaly) thinking anchor with Secondary 1 Express (G3) and Normal (Academic) (G2) students in 2022, this research demonstrated significant improvements in student performance and confidence levels during school-based assessments. The findings reveal that thinking anchors serve as effective scaffolding tools that reduce conceptual errors and enhance the quality and structure of student responses to skills-based geographical questions simultaneously.

Abstract

This paper examines the strengths and constraints of the Singapore Secondary Geography curriculum in advancing sustainability education and suggests that current approaches to sustainability can lead to simplified representations of climate solutions, limited engagement with social and ethical trade-offs, and insufficient attention to unequal impacts across places and communities, even within student-centred classroom contexts.Drawing on lesson examples, learning artefacts and student reflections, this paper illustrates how teacher curriculum-making enables the enacted curriculum to complement the intended curriculum in equipping students to think through systems, recognise contested sustainability pathways, and act as informed stewards of their environment. Through intentional task design, scaffolded inquiry and reflective dialogue, classroom enactment moves learning beyond discrete topics towards understanding the consequences and feedback loops across human and environmental systems. Sustainability is therefore approached not as arriving at a set of correct answers, but as exercising judgment through ethical
reasoning and careful considerations of trade-offs.

Abstract

Geography occupies a distinctive position in educational curriculum, often being tasked with the role of educating and advancing student knowledge in sustainability. However, contrasting geographical traditions, particularly positivism and humanism, has shaped the framing of sustainability in Singapore’s secondary school geography syllabuses. A close examination of the syllabuses reveals that although sustainability exists as an overarching thematic anchor across the topics, its articulation varies according to topical demands. However, if the curriculum sets out a fragmented landscape of learning about sustainability, its ability to move student behaviours towards sustainable praxis may be limited. This essay argues that there is room for a thorough interrogation of sustainability as a concept within the Singapore secondary school geography curriculum that goes beyond how it is presented in the syllabuses. Furthermore, a more meaningful engagement with the dynamic and highly principled nature of the concept could translate into more thoughtful and practising learners.

Abstract

Geography education in Singapore has evolved alongside national priorities, shifting toward a concept-based curriculum centred on sustainable development. This paper argues that the effectiveness of sustainability education partly depends on teachers’ underlying philosophical assumptions about geographical knowledge. The current syllabus reflects an interplay of positivistic, humanistic and critical traditions, requiring educators to navigate multiple epistemologies in their teaching. In addition, it is centered around sustainable development as a core anchor for geographical knowledge. As sustainability demands understanding long-term socio-environmental consequences, teachers must intentionally align philosophy, pedagogy and assessment to model conceptual, reflective and critical thinking. Ultimately, geography’s capacity to cultivate sustainability-minded students rests on philosophically aware educators who exercise discernment in classroom practice.

This paper investigates the impact of both Santo Antônio and Jirau mega dams on the downstream geomorphology of, more specifically, island and bar dynamics along the Madeira River in the Amazon. Water level data from gauge stations and remote sensing images from 1990 to 2019 were deployed to make sense of the changes in the number, area and volume of islands/bars downstream of the dams. The data indicated that both Santo Antônio and Jirau, which are run-of-river dams have not had significant impacts on the area and volume of islands/bars found in Madeira River’s five reaches. A reduction in the volume of islands/bars was marginally more substantial than a negligible reduction in their areal extent. Trapped sediments behind both dams could have accounted for the slight decrease in island/bar volume. Overall, this paper opens up a discussion on the sustainability of fluvial/geomorphological features and water regimes, alongside the installation of run-of-river dams as an allegedly more sustainable alternative to other kinds of hydraulic structures and non-renewable sources of energy. Student-teachers who are taking tertiary courses in physical Geography, as well as A Level Geography educators are likely to take interest in this in-depth and well contextualised case study of mega dams in Brazil.

Abstract
Sampling is a fundamental and essential component in geographical fieldwork. Sampling is the process of gathering data from purposefully selected sites, such that the data collected best represents the general phenomenon being studied. In geography education, teachers often have to look for suitable sites for students to conduct fieldwork, for example, which location to conduct interviews. However, many teachers are afraid to venture out into unchartered territories where the potential site for fieldwork is unfamiliar. This paper seeks to illustatre the use of GIS techniques to determine the suitability of an unfamiliar site for sampling in geographical fieldwork through coastal research done on a coastline along Cha-am, Thailand.

Unfamiliar territories
The research conducted was about the impact of coastal erosion on Cha-am’s beach and Cha-am south beach and the shops along the coast. The research was conceptualised in Singapore, hence making it a challenge to visit the research site beforehand. In addition, there was no prior secondary research about coastal erosion and coastal retreat along Cha-am’s coastline. To overcome this challenge, GoogleEarth and GIS remote sensing techniques were utilitised to determine the suitability of various sites for research on coastal erosion.

Utilising GoogleEarth Satellite Imagery
Firstly, GoogleEarth was used to get an overview of possible sites along Cha-am’s coastline. Through GoogleEarth, the coastline was analysed using satellite images from various time scales through the time slider feature in GoogleEarth. The satellite images revealed that there was indeed coastal retreat along Cha-am coast over the years. Hence, by comparing the coastline in the different time scales, two sites along Cha-am’s coastline were identified – one at Cha-am beach as a ‘low erosion site’ and the other at Cha-am south beach as a ‘high erosion site’ (Figure 1).

The ‘low erosion site’ was identified for having the least significant coastal retreat compared to the rest of the coastline. In addition, the ‘low erosion site’ had the largest stretch of beach, which is a key coastal depositional landform (Figures 2a, 2b and 2c).
