    "The American Statistical Association seeks to embrace science's inherent complexity and push for more data transparency by rejecting a common, oversimplified measure of statistical significance. March 15, 2016 By Colleen Flaherty Is the tyrannical reign of the P value finally ending (if it was ever tyrannical at all)? An unprecedented statement from the American Statistical Association seeks to usher in a "post-P

    First, the ongoing exploration of the reliability and validity of the psychometric assessment instrument designed to measure and stimulate change in learning power, for which I was one of three originators between 2000 and 2002. To date I have been able to collect large data sets (n=>50,000) and have published reliability and validity statistics in four  peer reviewed journal articles. Second, the application of the concept and assessment of learning power in pedagogy in school, community and corporate sectors, and in particular its contribution to personalisation of learning through authentic enquiry. Third, the contribution of learning power and enquiry to what we know about complexity in education, particularly through the development of systems learning and leadership as a vehicle for organisational transformation. Finally, the application of learning power assessment strategies to the emerging field of learning analytics and agent-based modelling.

    "Built as a Learning Tools Interoperability (LTI) integration for the learning management system Canvas, Threadz is a discussion visualization tool that adds graphs and statistics to online discussions. Online discussions provide valuable information about the dynamics of a course and its constituents. Much of this information is found within the content of the posts, but other elements are hidden within the social network connection and interactions between students and between students and instructors. Threadz is a tool that extracts this hidden information and puts it on display. The visual representations created from social network connections and interactions between students and instructors in a discussion assist in identifying specific behaviors and characteristics within the course, such as: learner isolation, non-integrated groups, instructor-centric discussions, and key integration (power) users and groups. By identifying these behaviors and characteristics, the instructor can affect change in these interactions to help make the discussions and classroom discourse more accessible to all."

Assessment and Analytics in Institutional Transformation (EDUCAUSE Review) | EDUCAUSE - 0 views

  • At the University of Maryland, Baltimore County (UMBC), we believe that process is an important factor in creating cultural change. We thus approach transformational initiatives by using the same scholarly rigor that we expect of any researcher. This involves (1) reviewing the literature and prior work in the area, (2) identifying critical factors and variables, (3) collecting data associated with these critical factors, (4) using rigorous statistical analysis and modeling of the question and factors, (5) developing hypotheses to influence the critical factors, and (6) collecting data based on the changes and assessing the results.
  • among predominantly white higher education institutions in the United States, UMBC has become the leading producer of African-American bachelor’s degree recipients who go on to earn Ph.D.’s in STEM fields. The program has been recognized by the National Science Foundation and the National Academies as a national model.
  • UMBC has recently begun a major effort focused on the success of transfer students in STEM majors. This effort, with pilot funding from the Bill and Melinda Gates Foundation, will look at how universities can partner with community colleges to prepare their graduates to successfully complete a bachelor’s degree in a STEM field.

  • Too often, IT organizations try to help by providing an analytics “dashboard” designed by a vendor that doesn’t know the institution. As a result, the dashboard indicators don’t focus on those key factors most needed at the institution and quickly become window-dressing.
  • IT organizations can support assessment by showing how data in separate systems can become very useful when captured and correlated. For example, UMBC has spent considerable effort to develop a reporting system based on our learning management system (LMS) data. This effort, led from within the IT organization, has helped the institution find new insights into the way faculty and students are using the LMS and has helped us improve the services we offer. We are now working to integrate this data into our institutional data warehouse and are leveraging access to important demographic data to better assess student risk factors and develop interventions.
  • the purpose of learning analytics is “to observe and understand learning behaviors in order to enable appropriate interventions.
  • the 1st International Conference on Learning Analytics and Knowledge (LAK) was held in Banff, Alberta, Canada, in early 2011 (https://tekri.athabascau.ca/analytics/)
  • At UMBC, we are using analytics and assessment to shine a light on students’ performance and behavior and to support teaching effectiveness. What has made the use of analytics and assessment particularly effective on our campus has been the insistence that all groups—faculty, staff, and students—take ownership of the challenge involving student performance and persistence.

    Assessment and analytics, supported by information technology, can change institutional culture and drive the transformation in student retention, graduation, and success. U.S. higher education has an extraordinary record of accomplishment in preparing students for leadership, in serving as a wellspring of research and creative endeavor, and in providing public service. Despite this success, colleges and universities are facing an unprecedented set of challenges. To maintain the country's global preeminence, those of us in higher education are being called on to expand the number of students we educate, increase the proportion of students in science, technology, engineering, and mathematics (STEM), and address the pervasive and long-standing underrepresentation of minorities who earn college degrees-all at a time when budgets are being reduced and questions about institutional efficiency and effectiveness are being raised.

    Features Gephi is a tool for people that have to explore and understand graphs. Like Photoshop but for data, the user interacts with the representation, manipulate the structures, shapes and colors to reveal hidden properties. The goal is to help data analysts to make hypothesis, intuitively discover patterns, isolate structure singularities or faults during data sourcing. It is a complementary tool to traditional statistics, as visual thinking with interactive interfaces is now recognized to facilitate reasoning. This is a software for Exploratory Data Analysis, a paradigm appeared in the Visual Analytics field of research.
