Abstract: In recent years, the most daring player in the social media arena proved to be the microblogging technology, the most energetic in this field being Twitter, raising the interest of the educational actors. A number of microblogging platforms dedicated to education were implemented, such as Edmodo, Plurk, Cirip.eu or Twiducate. In this context, the paper aims to provide an overall analysis of the microblogging platform Cirip.eu for educational directions such as: information and knowledge management, courses enhancement, delivering online courses, collaborative projects, communities of practice, hosting different workshops, conferences or scientific events, building e- portfolios, etc. Thus, the main aspects of the paper will regard the following: 1. The facilities offered by Cirip.eu recommend it as a modern and flexible mobile Social Learning Management System (mSLMS), integrating users' Personal Learning Environments; 2. How microblogging can be integrated with other Web2.0 technologies, and into the Open Educational Resources movement; 3. How the experience and the new pedagogical approach in using microblogging can be captured and formally represented as learning design objects; 4. How learning design objects can be shared, discussed, improved, reused on the microblogging platform.
The use of microblogging for field-based scientific research  [PDF]
Alberto Pepe,Matthew S. Mayernik
Computer Science , 2011, DOI: 10.1109/HICSS.2012.589
Abstract: Documenting the context in which data are collected is an integral part of the scientific research lifecycle. In field-based research, contextual information provides a detailed description of scientific practices and thus enables data interpretation and reuse. For field data, losing contextual information often means losing the data altogether. Yet, documenting the context of distributed, collaborative, field-based research can be a significant challenge due to the unpredictable nature of real-world settings and to the high degree of variability in data collection methods and scientific practices of different researchers. In this article, we propose the use of microblogging as a mechanism to support collection, ingestion, and publication of contextual information about the variegated digital artifacts that are produced in field research. We perform interviews with scholars involved in field-based environmental and urban sensing research, to determine the extent of adoption of Twitter and similar microblogging platforms and their potential use for field-specific research applications. Based on the results of these interviews as well as participant observation of field activities, we present the design, development, and pilot evaluation of a microblogging application integrated with an existing data collection platform on a handheld device. We investigate whether microblogging accommodates the variable and unpredictable nature of highly mobile research and whether it represents a suitable mechanism to document the context of field research data early in the scientific information lifecycle.

Abstract: Large scale analysis and statistics of socio-technical systems that just a few short years ago would have required the use of consistent economic and human resources can nowadays be conveniently performed by mining the enormous amount of digital data produced by human activities. Although a characterization of several aspects of our societies is emerging from the data revolution, a number of questions concerning the reliability and the biases inherent to the big data “proxies” of social life are still open. Here, we survey worldwide linguistic indicators and trends through the analysis of a large-scale dataset of microblogging posts. We show that available data allow for the study of language geography at scales ranging from country-level aggregation to specific city neighborhoods. The high resolution and coverage of the data allows us to investigate different indicators such as the linguistic homogeneity of different countries, the touristic seasonal patterns within countries and the geographical distribution of different languages in multilingual regions. This work highlights the potential of geolocalized studies of open data sources to improve current analysis and develop indicators for major social phenomena in specific communities.

International Journal of Interactive Mobile Technologies (iJIM) , 2009, DOI: 10.3991/ijim.v3s1.813
Abstract: This research reports an experiment which took place in an Arab middle school in Israel. The experiment was led by three pre-service teachers who were carrying out their final project in the field of teaching mathematics using mobile phones. The pre-service teachers worked with 32 eighth grade students to carry out authentic real life outdoor activities in the nature. We used discourse analysis and grounded theory to analyze the perceptions of the students regarding their mathematics learning using mobile phones. We found that the novelty of the experiment and the use of mobile phones in mathematics learning were the main characteristics perceived by the students as influencing their decision to join the experiment. Furthermore, the students perceived various qualities of the mathematics learning that were enabled by the use of mobile phones: (1) exploring mathematics independently (2) learning mathematics through collaboration and team work; where the collaboration is on equal terms (3) learning mathematics in a societal and humanistic environment (4) learning mathematics in authentic real life situations (5) visualizing mathematics and investigating it dynamically (6) carrying out diversified mathematical actions using new and advanced technologies (7) learning mathematics easily and efficiently. In the overall, the students were positively impressed by the potentialities and capabilities of the mobile phones used in the mathematics learning process. This indicates that mathematics education could benefit form utilizing these new technological tools.

Abstract: In this article, Terry Freedman looks at how microblogging services such as Twitter, Edmodo and Cirip are being used in education, both in the classroom and for professional development. Although microblogging does not, at first glance, look particularly useful for teaching and learning, the opposite turns out to be the case.
From Laboratory to Authentic Contexts: Two Studies of Pedagogical Reasoning Across Four Levels of Expertise  [cached]
Julien Mercier
World Journal of Education , 2012, DOI: 10.5430/wje.v2n4p2
Abstract: A cognitive model of how teachers plan instruction was validated in laboratory settings but remained to be tested empirically in authentic situations. The objective of this work is to describe and compare pedagogical reasoning in laboratory and authentic contexts and across expertise levels. The “state-driven hypothesis” and the “knowledge-driven hypothesis” were used in two studies to show how pedagogical reasoning was performed by novices and experts in laboratory (n=18) and in authentic context (n=14). Globally, the results show (1) similarities and differences in how pedagogical reasoning unfolds in laboratory and authentic contexts and (2) how domain knowledge influences only some aspects of this process. The work presented lays the foundations for the fine-grained study of how domain knowledge determines problem-solving in pedagogical-reasoning.

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0022656
Abstract: Microblogging and mobile devices appear to augment human social capabilities, which raises the question whether they remove cognitive or biological constraints on human communication. In this paper we analyze a dataset of Twitter conversations collected across six months involving 1.7 million individuals and test the theoretical cognitive limit on the number of stable social relationships known as Dunbar's number. We find that the data are in agreement with Dunbar's result; users can entertain a maximum of 100–200 stable relationships. Thus, the ‘economy of attention’ is limited in the online world by cognitive and biological constraints as predicted by Dunbar's theory. We propose a simple model for users' behavior that includes finite priority queuing and time resources that reproduces the observed social behavior.
Improved Twitter Sentiment Prediction through Cluster-then-Predict Model  [PDF]
Rishabh Soni,K. James Mathai
Computer Science , 2015,
Abstract: Over the past decade humans have experienced exponential growth in the use of online resources, in particular social media and microblogging websites such as Facebook, Twitter, YouTube and also mobile applications such as WhatsApp, Line, etc. Many companies have identified these resources as a rich mine of marketing knowledge. This knowledge provides valuable feedback which allows them to further develop the next generation of their product. In this paper, sentiment analysis of a product is performed by extracting tweets about that product and classifying the tweets showing it as positive and negative sentiment. The authors propose a hybrid approach which combines unsupervised learning in the form of K-means clustering to cluster the tweets and then performing supervised learning methods such as Decision Trees and Support Vector Machines for classification.
