General self-efficacy represents the global sense of personal capability across various situations and tasks. The aim of the present study was to develop and validate a single-item general self-efficacy scale which balances practical demands and psychometric concerns. The psychometric properties of the proposed Single-Item General Self-Efficacy Scale (GSE-SI) were examined among 231 Singaporean adults. Results based on three statistical methods demonstrated good reliability (.594 .607 and .726, respectively, M = .642), as compared with the reliability scores from other single-item scales. It also showed satisfactory criterion-related validity evidence (i.e., correlation with a multiple-item general self-efficacy scale, r = .795). Validity evidence based on relationships with other constructs was supported by the correlations between the scores of general self-efficacy and the scores of six relevant constructs (i.e., positive correlations with life satisfaction and positive emotions, negative correlations with negative emotions, task and perceived stress, and illness symptoms). More importantly, the GSE-SI and multiple-item scale scores showed consistent correlation patterns with their relevant constructs. Both GSE-SI and multiple-item scale scores significantly discriminated between the three clusters in a similar pattern. The present results show that the GSE-SI is a reliable and valid measure of general self-efficacy and can be recommended in future research to complement the constraints of multiple-item scales.

The prevalence rate of Problematic Internet Use (PIU) has increased globally over the years and is estimated at 7%. Studies report a significant association between PIU and Social and Emotional Learning skills, as well as negative effects such as loneliness. Taken together, the current study proposes a model of loneliness mediating SEL and PIU. The data used in this study was earlier collected from another study involving 1623 youths from 5 different schools that aims to study the trends and factors of PIU among Singapore adolescents. Secondary analysis of the data revealed that SEL, Loneliness and PIU are significantly correlated with each other. In addition, according to Baron and Kenny’s (1981) mediation model, loneliness was also found to be a full mediator of SEL and PIU, although the Sobel Test (1982) showed the indirect effect of SEL on PIU through loneliness is insignificant. The implications on policy and practice, as well as the directions for future research in view of the limitations of the study, are also discussed.

Virtual Reality (VR) and Immersive Virtual Environments (IVEs) are increasingly becoming employed in the classroom to facilitate embodied forms of experiential learning in sensorially rich contexts. This chapter presents the findings of a study conducted with 15-year-old students in a Singapore school. The study evaluated the effectiveness of IVEs as a novel pedagogical approach to the teaching of social and emotional competencies, in the context of Character and Citizenship Education; it sought to ascertain if the affordances of VR and IVEs—immersion, presence and embodiment—when accompanied by real-world narratives would facilitate greater empathy, perspective-taking and responsible decision-making. Students were divided into three treatment conditions: IVEs, “pen-and-paper” mental simulation and video-viewing, and each treatment contained a problem scenario that involved an ethical dilemma young people in Singapore today face. A quasi-experimental, pre-test post-test, non-equivalent group design was employed and the study adopted a mixed-method approach to data collection. The findings show how IVEs can effectively facilitate perspective-taking and empathy, and this is due to its ability to immerse the user in the fictional space of the narrative, thereby encouraging a deeper sense of presence and embodiment.

A problem with applications of innovations and technological tools such as the digital portfolio is that, while detailed conceptions and examples of digital portfolios exist, there is a chasm of practical advice that is sufficiently generic for guiding considerations on how to integrate digital portfolios into different learning environments. In this paper, it is argued that a powerful framework for guiding thinking about the integration of digital portfolios into teacher education is provided by cultural-historical activity theory or CHAT. CHAT is useful because it has been shown to provide a clear operational framework for the design of learning environments that support the integration of various technological tools.

Eportfolios were introduced into teacher education in the 1980s. Since then, educational researchers and practitioners have increasingly cited the use of portfolios as an important assessment and learning tool in teacher education programs. In the domain of teacher education, the need to improve quality, attain established standards and to resolve accreditation issues have led to the increased use of ePortfolios in many European states and others around the world (Granberg, 2010). An electronic portfolio (ePortfolio) is often defined as “a digitized collection of artifacts, including demonstrations, resources and accomplishments that represent an individual, group, community, organization, or institution. This collection can comprise of text-based, graphic or multimedia elements archived on a Web site or on other electronic media (Lorenzo & Ittelson, 2005, p. 3).” In pre-service teachers’ ePortfolios, artifacts can be samples of work that include lesson plans, stimulus materials, videos, pictures and picture files, classroom assignments, classroom tests, newsletters, and inservice materials produced by the pre-service teacher (Bruneau & Bie, 2010). With the creation of ePortfolios, student teachers can document their journey in becoming a teacher by selecting, sharing, and reflecting on artifacts such as educational philosophies, classroom management plans, unit and lesson plans, plans to meet the needs of diverse and special needs pupils, and video clips of practice teaching (e.g., Strudler & Wetzel, 2005). They can not only showcase their best work as a professional, but also exhibit the knowledge and skills in using technology.

Digital portfolios have gained an increasing prominence in teacher education programmes around the world as a consequence of research which purports their multiple benefits to users and of their potential to represent beginning teachers’ practices. Despite the current popularity of digital portfolios, the nature of their use is still not well understood. This article explores how student teachers use digital portfolios in a teacher education programme in Singapore from an economics perspective. It posits that the adoption of an economic lens would shed new light on existing understandings and raise awareness of how and why student teachers use digital portfolios the ways they do. Reference to a range of economic concepts would will help to better understand educational outcomes. The article considers the implications of the findings for informing how digital portfolios are implemented and raises issues for consideration in further implementation efforts and in future research.
