This study analyzed the influence of rhetoric in the endorsement text on the willingness of the crowd to participate in citizen science projects. Four categories of endorsers were studied: professors, students, industrial researchers, and amateur researchers. Using 1243 endorsement texts from 543 citizen science projects as the corpus, the effects…

Text provides a compelling example of unstructured data that can be used to motivate and explore classification problems. Challenges arise regarding the representation of features of text and student linkage between text representations as character strings and identification of features that embed connections with underlying phenomena. In order…

Political communication exemplifies rhetoric and propagandist approach in its various forms, among which the Aristotle's rhetorical theory and its three aspects, ethos, pathos and logos are the major ones. This study used these three as indicators of public rhetoric in the context of Indonesian parliamentarian speeches This study used a…

This article demonstrates how a digital environment offers new opportunities for transforming qualitative data into quantitative data in order to use data mining and information visualization for mixed methods research. The digital approach to mixed methods research is illustrated by a framework which combines qualitative methods of multimodal…

Classroom discourse is a core medium of instruction -- analyzing it can provide a window into teaching and learning as well as driving the development of new tools for improving instruction. We introduce the largest dataset of mathematics classroom transcripts available to researchers, and demonstrate how this data can help improve instruction.…

The proliferation of information technology tools in higher education has resulted in an explosion of data about students and their contexts. Yet, current policies governing these data are limited in their usefulness for informing students, instructors, and administrators of their rights and responsibilities related to data use because they are…

Knowledge regarding social information is commonly believed to be derived from sources such as formal relationships and interviews and can be plotted as complex networks. We explored whether social networks can also be extracted through other means by using language statistics. In three computational studies we computed first-order and…

Since 2007, 'Closing the Gap' between Indigenous and non-Indigenous people has been an ambition of Australian state and federal governments in areas including education, employment, and health. This paper examines media responses to government policies aimed at closing the achievement gap in schools. The paper analyses print and online newspaper…

Informed by critical data literacy efforts to promote social justice, this paper uses qualitative methods and data collected during two years of workplace ethnography to characterize the notion of critical novice data work. Specifically, we analyze everyday language used by novice data workers at DataWorks, an organization that trains and employs…

We still know relatively little about how researchers use qualitative data analysis software (QDAS) such as ATLAS.ti and NVivo. We conducted a discourse analysis of 763 empirical articles published from 1994 to 2013 that explored the language used by researchers when reporting QDAS use. We found that most researchers provided few details of their…

The assessment and understanding of students' ideas in discourse have often been a difficult problem for teachers to tackle. Recent innovations and technologies such as text mining can provide a partial solution by generating an estimated count of important keywords which are representative of ideas within discourse. However, investigating idea…

This case study provides an overview of a conversation analysis study that examines how the management of talk is accomplished by a chairperson in a teachers' meeting. The case describes each of the various steps of the conversation analysis study from deciding on an initial research focus to collecting, transcribing, and analyzing the data. It…

Interactivity is an important indicator of an educational app's reception. Since most educational apps are multimodal, it justifies a methodological initiative to understand meaningful involvement of multimodality in enacting and even amplifying interactivity in an educational app. Yet research so far has largely concentrated on algorithm…

In this article, we use grounded practical theory to develop a practical theory for using "difficult data" in Language and Social Interaction university classes. "Difficult data" are transcribed, audio/video-recorded data that contain language and ideologies that could be offensive, bigoted, or otherwise disturbing. We provide…

Objective: As children become increasingly exposed to health information and education, it is important to understand how these messages affect the way children speak about health and health behaviours. Children are social agents and co-constructors of their social worlds. Exploring how pre-school children speak about health and health-promoting…
