    Using intervention-oriented evaluation to diagnose and correct students’ persistent climate change misconceptions: A Singapore case study
    (Elsevier, 2015)
    Pascua, Liberty
    ;
    The evaluation of classroom-based educational interventions is fraught with tensions, the most critical of which is choosing between focusing the inquiry on measuring the effects of treatment or in proximately utilizing the data to improve practice. This paper attempted to achieve both goals through the use of intervention-oriented evaluation of a professional development programme intended to diagnose and correct students’ misconceptions of climate change. Data was gathered, monitored and analyzed in three stages of a time-series design: the baseline, treatment and follow-up stages. The evaluation itself was the ‘intervention’ such that the data was allowed to ‘contaminate’ the treatment. This was achieved through giving the teacher unimpeded access to the collected information and to introduce midcourse corrections as she saw fit to her instruction. Results showed a significant development in students’ conceptual understanding only after the teacher’s decision to use direct and explicit refutation of misconceptions. Due to the accessibility of feedback, it was possible to locate specifically at which point in the process that the intervention was most effective. The efficacy of the intervention was then measured through comparing the scores across the three research stages. The inclusion of a comparison group to the design is recommended for future studies.

    Uncovering the nexus between scientific discourse and school geography in Singapore students’ understanding of climate change
    (Texas State University, 2014) ;
    Pascua, Liberty
    This paper describes a baseline empirical study of Singapore secondary students' understanding of climate change . It reports that despite evidence of significant awareness on the topic , what learner's think they know does not match up with what they really know. Like other students around the world, their understanding of the phenomenon is not deep enough for accurate definition, explanation and linking of critical concepts together coherently and correctly. The paper critically examines how the introduction of a new national syllabus in geography in Singapore at grade 9level considers current developments in scientific discourse and affords the opportunity to help students develop values , knowledge, and skills to engage the climate change topic. The study argues for geographic education to be responsive in addressing gaps identified through updating the curriculum with current scientific discourse and by providing skills for students to engage a growing volume of information on climate change from various media.

    Using iTunes U for learning geography
    A reflection on using iTunes U as a platform for teaching and learning Geography will be presented. Arising from an altruistic interest in exploring the affordances of new technology, as well as balancing the pragmatic needs of developing innovative approaches to conducting eLearning lessons, the author developed one of the first iTunes U courses for the National Institute of Education, Singapore - a topic on atmospheric circulation. Available free on the iTunes U store, the free–access course has been subscribed by the public in the order of threefold the number of students in the author’s class. This exposition will consider the issues of the rationale for developing the iTunes U course, the design considerations in relation to the affordances of the technology, and most importantly the limitations and recommended improvements. The presentation will also include a very short demonstration on the functionalities of using iTunes U for learning Geography.

    Is Singapore’s school geography relevant to our changing world?
    (Eskisehir Osmangazi University, 2011)
    How school geography should be taught has been a longstanding issue for geography educators. In some countries, state or national level curriculum predicates how the subject should be taught in schools. This paper examines these questions in relation to existing frameworks of conceptualizing school geography, such as the International Charter on Geographical Education. School geography in Singapore has evolved from regional geography to thematic geography to systematic geography. A review of the curriculum in 2007 resulted in a distinct form of school geography unprecedented in Singapore’s education history. Today, school geography in Singapore is learnt conceptually with national level assessment designed to that end. To what extent is this evolution in curriculum design in step with changes in our world? In response to the changes in school geography, pre-service and in-service teacher training has also responded by focusing on conceptual learning and inquiry. This paper will explore the state of school geography curricula in Singapore today, and the curriculum of teacher training, with the intent to critically discuss the state of geography education in Singapore. Although geography has remained a disciplinary subject whose place has yet been disputed, the big question of why study geography in the first place needs to be answered to ensure its continued survival. In particular, school geography will be examined for its relevance to a fast changing world. This critique ends by offering a reason to how geography plays an important role in education for sustainable development, and its relevance to Singaporeans or even any citizen of the world.

    Design experiment or experimental design? Towards a methodology to study
    (Texas State University, 2010) ;

    Arising from the metaphor and methods of the design and engineering fields, design experiment is a methodology whereby an artifact or intervention is designed based on a known theory with the goal of improving the artefact or intervention thrqugh the inquiry. Experimental design, on the other hand, refers to an investigative method in which variability in the experimental subjects or objects are compared. In developing a methodology to investigate if Geographic Information System (GIS) use with the problem based learning (PBL) approach will result in higher order learning outcomes, the concepts of design experiment or design-based research (DBR) and experimental design were considered. A combination of both approaches was adapted into a hybrid methodology that draws on the benefits of these two approaches to address the research question raised. In particular, experimental design was used in combination with microethnography to inform the design process of this study. The experimental design part of the study found that GIS use with PBL resulted in higher order cognitive skills use , such as applying and evaluating, while the use of recall reduced. Studying the preliminary results of the micro-ethnography showed that the affordances of the GIS technology such as spatial analysis tools helped students develop cognitive skills of analysis and evaluation. While initial conception of the methodology was a hybrid of both experimental design and design experiment, the resultant methodology was primarily a DBR which addressed the process of learning and the way that learning is supported by GIS. A key outcome in this methodology evaluation process is the importance of having a practitioner on the research team.

    ‘The hole in the sky causes global warming’: A case study of secondary school students’ climate change alternative conceptions
    (Eskisehir Osmangazi University, 2015) ;
    Pascua, Liberty
    This study identified secondary school students’ alternative conceptions (ACs) of climate change and their resistance to instruction. Using a case-based approach, a diagnostic test was administered to Secondary 3 male students in a pre-test and post-test. The ACs identified in the pre-test were on the causes of climate change, the natural greenhouse effect and its properties, the enhancement of the greenhouse effect, the elements involved in heat-trapping and their characteristics. There were also notable ACs on the effects of climate change, mostly on how the phenomenon is related to non-atmospheric events such as tsunami, earthquakes, acid rain and skin cancer. The students confuse the Montreal with the Kyoto Protocol as the primary treaty aimed at curbing greenhouse gas emissions. Whereas there was significant improvement in students’ understanding in the post-test, the distribution of responses for each of the ACs showed that the reduction in erroneous responses was not sufficient to reject the ACs fully. The authors recommend that instruction should move beyond patchwork pedagogy to a more explicit acknowledgement, incorporation and direct refutation of misconceived knowledge structures.

    Field inquiry for Singapore geography teachers
    Vietnam’s tourism industry has high growth potential with forecasts of double digit growth in the next few years, as the tourism industry contributed more than 13% of its GPD even during the global economic recession in 2009 (RNCOS Market Research, 2010). With this unprecedented rate of growth in the tourism industry, two important questions arise. What are the causes of this growth and what is the impact of this growth? The Singapore Teachers’ fieldtrip offers opportunities for teachers to deepen their content and contextual understanding of Hanoi, as well as a chance to foray into conducting field based enquiry. In Singapore, a revised Geography syllabus will be implemented for the GCE ‘O’ levels in 2013 for Secondary 3 students. A key feature of this revised syllabus is the use of an enquiry approach in the teaching and learning of Geography to engage independent learning, critical thinking, reflective thinking and enquiry. In particular, the “enquiry approach” proposed in this revised syllabus is contingent on both fieldwork and classroom learning. This workshop draws on the experience in the field to advance the discussion on the enquiry process.

    Conceptualizing climate change education: An overview
    (2012) ;
    Pascua, Liberty
    This presentation provides a brief overview on some key concepts in determining the outcomes of climate change education including the knowledge domains on the science, impacts and management of climate change, as well as taking into consideration the cognitive domains of outcomes such as factual recall, deep understanding, skill in analyzing climate change information, for example. The presentation will also discuss the concepts of awareness, knowledge, attitude and action in developing curriculum for learning about climate change. The ultimate aim of education is not just to “inform people, but to change them” (UNESCO, 1997). It is based on this philosophy that CCE should transform learners from knowing and doing something about climate change to being a global citizen ready to engage the issues of climate change.
