Peer assessment and knowledge discovering in a community of learners

Thanks to the exponential growth of the Internet, Distance Education is becoming more and more strategic in many fields of daily life. Its main advantage is that students can learn through appropriate web platforms that allow them to take advantage of multimedia and interactive teaching materials, without constraints neither of time nor of space. Today, in fact, the Internet offers many platforms suitable for this purpose, such as Moodle, ATutor and others. Coursera is another example of a platform that offers different courses to thousands of enrolled students. This approach to learning is, however, posing new problems such as that of the assessment of the learning status of the learner in the case where there were thousands of students following a course, as is in Massive On-line Courses (MOOC). The Peer Assessment can therefore be a solution to this problem: evaluation takes place between peers, creating a dynamic in the community of learners that evolves autonomously. In this article, we present a first step towards this direction through a peer assessment mechanism led by the teacher who intervenes by evaluating a very small part of the students. Through a mechanism based on machine learning, and in particular on a modified form of K-NN, given the teacher’s grades, the system should converge towards an evaluation that is as similar as possible to the one that the teacher would have given. An experiment is presented with encouraging results

Assessment for learning? Thinking outside the (black) box

This article draws on a survey of 83 teachers, to explore the concepts of ‘assessment for learning’, ‘assessment’ and ‘learning’. ‘Assessment for learning’ is categorized as meaning: monitoring pupils’ performance against targets or objectives; using assessment to inform next steps in teaching and learning; teachers giving feedback for improvement; (teachers) learning about children’s learning; children taking some control of their own learning and assessment; and turning assessment into a learning event. Conceptions of assessment include assessment-as-measurement and assessment-as-inquiry. These conceptions are related to two conceptions of learning: learningas- attaining-objectives and learning-as-the-construction-of-knowledge. The conceptions of assessment-as-measurement and learning-as-attaining-objectives are dominant in English educational policy today. The article suggests that these conceptions need to be challenged and expanded, since conceptions held by those who have power in education determine what sort of assessment and learning happen in the classroom, and therefore the quality of the student’s learning processes and products

Embedding accessibility and usability: considerations for e-learning research and development projects

This paper makes the case that if e‐learning research and development projects are to be successfully adopted in real‐world teaching and learning contexts, then they must effectively address accessibility and usability issues; and that these need to be integrated throughout the project. As such, accessibility and usability issues need to be made explicit in project documentation, along with allocation of appropriate resources and time. We argue that accessibility and usability are intrinsically inter‐linked. An integrated accessibility and usability evaluation methodology that we have developed is presented and discussed. The paper draws on a series of mini‐case studies from e‐learning projects undertaken over the past 10 years at the Open University

Recommended Practices for Library Collections for English Language Learners

The number of English Language Learners (ELLs) in elementary and secondary education continues to increase and diversify. To serve the needs of this student population, both P12 school libraries and university level curriculum materials libraries must modify their collections to prepare ELL students and classroom educators for success. One such college library recently undertook a project in which we surveyed the literature and current practice regarding ELL collections and services. This presentation covers the results of this study and encourages the provision of a diverse range of quality materials. Grounded in the specific context of one large school district, as well as the broader context of changing U.S. demographics, recommendations include acquiring materials that support the home languages of students and maximizing visibility of other unique formats that will benefit ELLs and other student populations, such as graphic novels and hi-lo books

Motivational Social Visualizations for Personalized E-Learning

A large number of educational resources is now available on the Web to support both regular classroom learning and online learning. However, the abundance of available content produces at least two problems: how to help students find the most appropriate resources, and how to engage them into using these resources and benefiting from them. Personalized and social learning have been suggested as potential methods for addressing these problems. Our work presented in this paper attempts to combine the ideas of personalized and social learning. We introduce Progressor + , an innovative Web-based interface that helps students find the most relevant resources in a large collection of self-assessment questions and programming examples. We also present the results of a classroom study of the Progressor +  in an undergraduate class. The data revealed the motivational impact of the personalized social guidance provided by the system in the target context. The interface encouraged students to explore more educational resources and motivated them to do some work ahead of the course schedule. The increase in diversity of explored content resulted in improving students’ problem solving success. A deeper analysis of the social guidance mechanism revealed that it is based on the leading behavior of the strong students, who discovered the most relevant resources and created trails for weaker students to follow. The study results also demonstrate that students were more engaged with the system: they spent more time in working with self-assessment questions and annotated examples, attempted more questions, and achieved higher success rates in answering them

Learning the Lessons of Openness

The Open Educational Resources (OER) movement has built up a record of experience and achievements since it was formed 10 years ago as an identifiable approach to sharing online learning materials. In its initial phase, much activity was driven by ideals and interest in finding new ways to release content, with less direct research and reflection on the process. It is now important to consider the impact of OER and the types of evidence that are being generated across initiatives, organisations and individuals. Drawing on the work of OLnet (http://olnet.org) in bringing people together through fellowships, research projects and supporting collective intelligence about OER, we discuss the key challenges facing the OER movement. We go on to consider these challenges in the context of another project, Bridge to Success (http://b2s.aacc.edu), identifying the services which can support open education in the future
