Do digital natives differ by computer self-efficacy and experience? An empirical study

This study serves to validate a Chinese translation of the Digital Native Assessment Scale (C-DNAS) and assess if significant differences exist between a sample of students and teachers from a culture different than the one used in the development of the DNAS. Participants were 402 university students from one province in Mainland China. Results of the confirmatory factor analysis revealed that the C-DNAS possessed a stable factorial structure and was a valid measure among Chinese-speaking participants in Mainland China. Tests of measurement invariance revealed score equivalence among the students for each of the four factors of the C-DNAS: grew up with technology; comfortable with multitasking; reliant on graphics for communication; and thrive on instant gratifications and rewards, by computer self-efficacy and experience. Finally, tests of latent mean differences revealed significant differences in each of the four factors by computer experience but not by computer self-efficacy. Implications for research are discussed.     

Minimax optimal control of linear system with input-dependent uncertainty

In this paper, the quadratic minimax optimal control of linear system with input-dependent uncertainty is studied. We show that it admits a unique solution and can be approximated by a sequence of finite-dimensional minimax optimal parameter selection problems. These finite-dimensional minimax optimal parameter selection problems are further reduced to scalar optimization problems which also admit unique solutions. Thus, the original minimax optimal control problem is solved via solving a sequence of simple scalar optimization problems. Numerical experiments are presented to illustrate the developed method.     

Structuring professional dialogue through protocols: a study among elementary English teachers in Taiwan

This study focuses on the integration of protocols into elementary school English teacher’s professional dialogue and discusses the influence of protocols on teacher’s teaching and learning. Based on the analysis of documents, observations, and interviews, this study concludes that the introduction of protocols to elementary school English teachers led them to discuss their classroom practice and gain professional learning in instructional strategies and student learning during the professional dialogue. However, English teacher’s lack of experience in using protocols led to interruptions during the professional dialogue. Suggestions for effective protocol-based professional dialogue are provided.

     

Relooking Assessment: A Study on Assessing Developmental Learning Outcomes in Toddlers

In most countries the funding for early childhood education has increased and governments in some countries have taken serious steps to bring about positive change in the profession. However, the increase in funding by governments and other funding organisations around the world has, understandably, attracted increased accountability as these organisations need to know that their financial investments are achieving desired outcomes. To seek evidence that positive learning outcomes have indeed been achieved through these investments is a reasonable request, and there is a shared responsibility and accountability for professionals to provide appropriate evidence. The downside, however, can be the request for standardised test information, as if performance on such tests provides proof of all desired outcomes. More than ever before, it is important for early childhood educators to be able to provide accurate, objective information about children’s assessment in ways other than by standardised testing, which may not reflect the complex reality of children’s lives. This paper reports on a research study in Singapore that investigated curriculum effectiveness using developmental learning outcomes as a means of assessing children. The research was devised to examine if eight specified broad developmental learning outcomes could measure the effectiveness of the curriculum by assessing children’s learning as shown in qualitative data. Practical examples showed evidence of children’s learning and the role of the educator in facilitating and documenting developmental learning outcomes.     

The role of model building in problem solving and conceptual change

This study examines the effects of the activity of building systems models for school-based problems on problem solving and on conceptual change in elementary science classes. During a unit on the water cycle in an Asian elementary school, students constructed systems models of the water cycle. We found that representing ill-structured problems as system models improves problem solving as well as creating beneficial conceptual change related to the topic.

Isolation and distinctiveness in the design of e-learning systems influence user preferences

When faced with excessive detail in an online environment, typical users have difficulty processing all the elements of representation. This in turn creates cognitive overload, which narrows the user's focus to a few select items. In the context of e-learning, we translated this aspect as the learner's demand for a system that facilitates the retrieval of learning content – one in which the representation is easy to read and understand. We hypothesized that the representation of content in an e-learning system's design is an important antecedent for learner preferences. The aspects of isolation and distinctiveness were incorporated into the design of e-learning representation as an attempt to promote student cognition. Following its development, the model was empirically validated by conducting a survey of 300 university students. We found that isolation and distinctiveness in the design elements appeared to facilitate the ability of students to read and remember online learning content. This in turn was found to drive user preferences for using e-learning systems. The findings provide designers with managerial insights for enticing learners to continue using e-learning systems.     

Professionalising teaching: a corpus-based approach to the professional development of teachers in Singapore

This study explores the use of a corpus of classroom discourse data (Singapore Corpus of Research in Education or SCoRE) to facilitate the professional development of English language (EL) teachers in Singapore. A survey was first conducted to probe the knowledge base and belief system of EL teachers in three key domains: epistemology, pedagogy, and discourse. This was followed by a discourse analysis of the SCoRE corpus to mine resources that could address the specific professional needs of teachers identified through the survey. Survey findings suggest that EL teachers in Singapore are less secure in epistemology than pedagogy or discourse-related issues. The efficacy of using corpus-based materials to help teachers reflect on and develop their professional competencies was tested through a workshop. The paper concludes with a discussion of the implications of using authentic and situated corpus resources to facilitate teachers’ reflective practice and professional development.
