Making sense of learner and learning Big Data: reviewing five years of Data Wrangling at the Open University UK

Most distance learning institutions collect vast amounts of learning data. Making sense of this ‘Big Data’ can be a challenge, in particular when data are stored at different data warehouses and require advanced statistical skills to interpret complex patterns of data. As a leading institute on learning analytics, the Open University UK instigated in 2012 a Data Wrangling initiative. This provided every Faculty with a dedicated academic with expertise data analysis and whose task is to provide strategic, pedagogical and sense-making advice to staff and senior management. Given substantial changes within the OU (e.g. new Faculty structure, real-time dashboards, two large-scale adoptions of predictive analytics approaches, increased reliance on analytics), this embedded case study provides an in-depth review of lessons learned of five years of data wrangling. We will elaborate on the design of the new structure, its strengths and potential weaknesses, and affordances to be adopted by other institutions.     

Understanding and Learning-to-explain by Representing Mathematics: Epistemological Dilemmas Facing Teacher Educators in the Secondary Mathematics ``Methods' Course

Building on the work of Ball and McDiarmid,this study provides an equivalent at thesecondary level to the work of Liping Ma at theelementary level in that it provides a betterunderstanding of the conceptual knowledge ofschool mathematics held by prospectivesecondary teachers, along with examples of thesorts of knowledge needed to teach forunderstanding within the domain of integersubtraction. Part of an eight-yearlongitudinal study of secondary teachercandidates' conceptions of instructionalexplanations, this analysis of interaction inthe author's methods course and its discussionof epistemological obstacles and changescombines subject-matter and interactionistperspectives. The author concludes thatsecondary teacher candidates can deepen theirrelational knowledge of secondary mathematicswithin a methods course by focusing oninstructional explanations.     

Girls in science — An evaluation of one school's approach to the gender bias in science

Conclusions As the pilot project has only been in operation for one semester there are no profound statements that can be made. What we have at present is the base information for comparison of all data over the duration of the project. Cross tabulation of the data to date has begun. However it should be re-iterated here that there appears to be a lack of understanding by the parents' as to the reason for the all-girls classes at the school and that this situation may be due to the fact that in this school community we have the typical sex-stereotyping roles and attitudes existing. The big question is, Will this intervention strategy of single-sex science classes be effective in altering the girls views about what is appropriate for them to study or follow as a career?     

Learning consequences for university students using computerized mastery testing

Mastery learning, it is claimed, is among the most successful practices in higher education. Evidence supporting this claim has recently been criticized as empirically weak. This experiment employed a four-group, pre-post design to examine the learning consequences of a computer-administered mastery-testing approach in comparison with a seminar-discussion approach in a third-year university course. The mastery-testing approach generated significantly higher learning achievement than did the seminar-discussion approach. Replication and extension of this research approach are recommended to support generalizations across mastery-testing techniques, delivery systems, and disciplines.     

Erratum to: Effect of Current Electricity Simulation Supported Learning on the Conceptual Understanding of Elementary and Secondary Teachers

This study examined the impact of computer simulation and supported science learning on a teacher’s understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers’ concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting interactions were observed during the data analysis. The first was the difference between Elementary and Secondary teachers. Both groups had significant gains, with large effect sizes, but the Elementary teachers (Pre-Mean = 3.70, Post-Mean = 7.51) started lower and ended higher exhibiting a significantly larger gain than the Secondary teachers (Pre-Mean = 4.96, Post-Mean = 6.71). The second interaction was the impact of gender. Both groups showed significant gains, with large effect sizes, but females (Pre-Mean = 3.90, Post-Mean = 7.21) gained significantly more than males (Pre-Mean = 5.13, Post-Mean = 7.01). These results confirm that computer simulation supported science learning can have a positive effect on concept attainment in teachers.     

Teaching about the importance of trees: a study with young children

This paper reports on a study undertaken with the primary aim of investigating the effect of the storytelling teaching approach on kindergarten children's retention of ideas about the importance of trees. The study also assessed the effect of storytelling on children's intention to participate in a tree planting activity that they had to select from a list of activities. The story that was created included such elements as binary opposites, mental images, mystery, and wonder, according to Kieran Egan's theory. The study utilized a two‐group design, was conducted in three phases (pre‐test, intervention, and post‐test), lasted 11 weeks, and its results provide evidence of the effectiveness of the storytelling approach when compared with the traditional method of expository teaching complemented with visual images (pictures) of trees and their importance to human beings. The pedagogical appropriateness of the story, which was based upon the binary pair of opposites ‘security–insecurity’, is also discussed in the paper.
