    Papamitsiou, Z., & Economides, A. (2014). Learning Analytics and Educational Data Mining in Practice: A Systematic Literature Review of Empirical Evidence. Educational Technology & Society, 17 (4), 49-64. This paper aims to provide the reader with a comprehensive background for understanding current knowledge on Learning Analytics (LA) and Educational Data Mining (EDM) and its impact on adaptive learning. It constitutes an overview of empirical evidence behind key objectives of the potential adoption of LA/EDM in generic educational strategic planning. We examined the literature on experimental case studies conducted in the domain during the past six years (2008-2013). Search terms identified 209 mature pieces of research work, but inclusion criteria limited the key studies to 40. We analyzed the research questions, methodology and findings of these published papers and categorized them accordingly. We used non-statistical methods to evaluate and interpret findings of the collected studies. The results have highlighted four distinct major directions of the LA/EDM empirical research. We discuss on the emerged added value of LA/EDM research and highlight the significance of further implications. Finally, we set our thoughts on possible uncharted key questions to investigate both from pedagogical and technical considerations.

  • the learner model should be updated rapidly to reflect near real-time learner success and activity so that decisions are not made on out-dated models

Unstructured data is worth the effort when you've got the right tools - O'Reilly Radar - 2 views

  • With regard to the challenges, enterprise data is very messy, inconsistent, and spread out across multiple internal systems and applications. APIs like the ones we're working on can bring consistency and structure to a company's legacy data.

Just to Clarify: Stories are the Last Mile in Big Data - 3 views

  • Once configured, the system is then able to generate stories at scale without any further human intervention.

      anyone else have a problem with this?
  • For any pool of data, there are always going to be multiple stakeholders, and they should each be receiving their own targeted messaging.
  • But the last mile has to be the Story; the Story that communicates what is happening in the world, and what needs to be done to fix the problems and exploit the opportunities that analysis exposes
  •  
    Data alone isn't the answer. In fact, from a business perspective, the Data is still part of problem. Insight is the answer, which is derived from the Data.

Nothing New About Asking Questions. The Right Ones. - Neoteny - 0 views

  •  
    There are plenty of reasons to be skeptical about the BD market. But big data probably deserves a place in overall enterprise IT strategy for generating business insight. Best practices include generating a list of important challenges or questions that the current approach to data does not address. Could big data deliver the answers enterprises are looking for? If so, then it's all about discipline. A disciplined, targeted approach to big data - one focused on answering very specific questions. (my emphasis - I'll get to those later)

U. of Texas Adopts Plan to Publish Performance Data on Professors and Campuses - Faculty - The Chronicle of Higher Education - 2 views

    • Tony Searl
       
      as I attempted to raise during LAK11, intent is critical. If LAK is primarily accountability driven, then more complex outcomes available IF questioning of data is deeper, may be missed (or ignored/buried/not sought)
  • Among other things, the system will report such factors as research expenditures, publications, teaching evaluations, and external support.
    • Tony Searl
       
      myschool is already developing into such a site. Insightful LAK, with holistic intention, not narow agendas, is preferable. Metrics, data, inclusions and questions need bipartisan support IF education is to be apolitical.
  • That was a swipe at the Texas Public Policy Foundation, a conservative think tank supported by Gov. Rick Perry that has advocated a controversial blueprint known as the "Seven Solutions" to higher education

      intent, questions asked, data deemed inclusive, all crucial for LAK outcomes. Enormous potential for misrepresentations exist IF analytics is poorly conceived and managed.

      exact definition of intent of our 2 year old myschool data
  •  
    The plan unveiled on Thursday designates money to create a "dashboard"-an interactive, online database-to give students, parents, and legislators access to detailed measures of departments' and colleges' productivity and efficiency. data on individual professors will probably also be included, although Dr. Cigarroa stressed that each campus would be able to develop its own system of metrics and the details have not yet been worked out

Daily Kos: UPDATED: The HB Gary Email That Should Concern Us All - 0 views

  • According to an embedded MS Word document found in one of the HBGary emails, it involves creating an army of sockpuppets, with sophisticated "persona management" software that allows a small team of only a few people to appear to be many, while keeping the personas from accidentally cross-contaminating each other. Then, to top it off, the team can actually automate some functions so one persona can appear to be an entire Brooks Brothers riot online.
  • Using the assigned social media accounts we can automate the posting of content that is relevant to the persona.
  •  There are a variety of social media tricks we can use to add a level of realness to all fictitious personas

  • Really? I thought. How do we know if those are real people? Twitter has to be the easiest thing to fake and to automate with retweets and 180 characrer max sentences. To the extent that the propaganda technique known as "Bandwagon" is an effective form of persuasion, which it definitely is, the ability for a few people to infiltrate a blog or social media site and appear to be many people, all taking one position in a debate, all agreeing, for example, that so and so is not credible, or a crook, is an incredibly powerful weapon.
  • I believe there are many people though who will base their judgment on rumors and mob attacks. And for those people, a fake mob can be really effective.

      why?
  • thanks to various Hadoop optimizations, complementary technologies and advanced algorithms, real-time analytics are becoming a real possibility
  • react promptly to sensor readings or analyze web logs as they are generated because that type of information becomes quickly obsolete.

Action Analytics: Measuring and Improving Performance That Matters in Higher Education (EDUCAUSE Review) | EDUCAUSE - 0 views

  •  
    For the past several years, EDUCAUSE publications have described the emergence of two complementary forces: (1) the growth of "academic analytics" in higher education and the knowledge services needed to support seamless sharing and leveraging of contextualized data/information; and (2) the escalating accountability demands that are driving performance measurement and improvement initiatives. These forces converged in the July/August 2007 issue of EDUCAUSE Review, which showcased their potentially transformative impacts on higher education
