title: Twitter in education

authors: Wright, Noeline

abstract: This special issue of e-Learning and Digital Media arose from a chance discussion at lunch one day, when one of us mentioned to the outgoing editors of this journal that she had just managed to connect with someone from the other side of the world (they must have been up late!) and share ideas of interest to us both, particularly through using the DM (direct message) function in Twitter as a private conversation.

title: Understanding the causes and consequences of variability in infant ERP editing practices.

authors: Monroy, Claire

subjects: ERP methodology

abstract: The current study examined the effects of variability on infant event-related potential (ERP) data editing methods. A widespread approach for analyzing infant ERPs is through a trial-by-trial editing process. Researchers identify electroencephalogram (EEG) channels containing artifacts and reject trials that are judged to contain excessive noise. This process can be performed manually by experienced researchers, partially automated by specialized software, or completely automated using an artifact-detection algorithm. Here, we compared the editing process from four different editors-three human experts and an automated algorithm-on the final ERP from an existing infant EEG dataset. Findings reveal that agreement between editors was low, for both the numbers of included trials and of interpolated channels. Critically, variability resulted in differences in the final ERP morphology and in the statistical results of the target ERP that each editor obtained. We also analyzed sources of disagreement by estimating the EEG characteristics that each human editor considered for accepting an ERP trial. In sum, our study reveals significant variability in ERP data editing pipelines, which has important consequences for the final ERP results. These findings represent an important step toward developing best practices for ERP editing methods in infancy research.

title: Te Puni Rumaki – Strengthening Māori medium initial teacher education

authors: Tamatea, Karaitiana

abstract: The delivery of initial teacher education for Māori medium contexts in Aotearoa seeks to support the revitalization of the indigenous language and practices in collaboration with the current education system. This presentation introduces a research project begun early in 2013 with providers, student teachers, schools and communities involved in respective Māori medium programmes. This research project has a "positive output approach" where fundamental elements to the success of these various programmes are shared. The wide range of Māori medium initial teacher education settings is investigated. Consequences from the research findings will also be discussed.
