In this paper a learning analytics dashboard for MOOCs is proposed. It visualises the progress of learners' activity taking into account navigation, social interactions and interaction with educational resources. This approach was tested with the MOOCs created by the University Autonóma of Madrid (Spain) in the edX platform. Nowadays, the dashboard is being improved taking into account the received feedback from MOOCs instructors and assistants. Finally, a new version is presented to work along with edX and Open edX.

Online learning environments are being deployed globally to offer learning opportunities to diverse student communities. We propose the deployment of such an environment in low-resource after-school settings across India. We draw on preliminary research conducted in summer 2015 that leveraged existing ties with an NGO working across 35 after-school classrooms. Our larger goal is to (1) support tutors in curating and distributing learning content to students, (2) engage students in a mobile, networked learning environment where they can share and collaborate, and (3) evaluate the feasibility of online learning environments for low-resource contexts. In this submission, our focus is on the first component.

Online tests have been identified as a core learning activity. Unlike conventional online tests, which cannot completely reflect students' learning status, two-tier tests not only consider students' answers, but also take into account reasons for their answers. Thus, research into a two-tier test had mushroomed but few studies examined why the two-tier test approach was effective. To this end, we conducted an empirical study, where a lag sequential analysis was used to analyze behavior patterns. The results indicated students with the two-tier test demonstrated different behaviors which develop "breadth to depth" and "depth to breadth" strategies.

We seek to automatically identify which items to include in a set of curriculum, and how to adaptively select these items, in order to maximize student performance on some specified set of learning objectives. Our experimental results with a histogram tutoring system suggest that Bayesian Optimization can quickly (with only a small amount of student data) find good parameters, and may help instructors identify misalignment between their course, and their desired learning objectives.

Cheating in computer science classes can damage the reputation of institutions and their students. It is therefore essential to routinely authenticate student submissions with available software plagiarism detection algorithms such as Measure of Software Similarity (MOSS). Scaling this task for large classes where assignments are repeated each semester adds complexity and increases the instructor workload. The MOSS Tool for Addressing Plagiarism at Scale (MOSS-TAPS), organizes the MOSS submission task in courses that repeat coding assignments. In a recent use-case in the Online Master of Science in Computer Science (OMSCS) program at the Georgia Institute of Technology, the instructor time spent was reduced from 50 hours to only 10 minutes using the managed submission tool design presented here. MOSS-TAPS provides persistent configuration, supports a mixture of software languages and file organizations, and is implemented in pure Java for cross-platform compatibility.

The study presented in this paper deals with copying answers in MOOCs. Our findings show that a significant fraction of the certificate earners in the course that we studied have used what we call harvesting accounts to find correct answers that they later submitted in their main account, the account for which they earned a certificate. In total, around 2.5% of the users who earned a certificate in the course obtained the majority of their points by using this method, and around 10% of them used it to some extent. This paper has two main goals. The first is to define the phenomenon and demonstrate its severity. The second is characterizing key factors within the course that affect it, and suggesting possible remedies that are likely to decrease the amount of cheating. The immediate implication of this study is to MOOCs. However, we believe that the results generalize beyond MOOCs, since this strategy can be used in any learning environments that do not identify all registrants.

While MOOCs and other forms of large-scale learning are of growing importance, the vast majority of tertiary students still study in traditional face-to-face settings. This paper examines some of the challenges in attempting to apply the benefits of large-scale learning to these settings, building on a growing repository of cross-institutional data.

Online educational tools often generate learning data, and sharing such data between tutors and students can often improve learning outcomes. Unfortunately the process of sharing learning data today is not always transparent to students. Our aim is to improve the transparency and user control aspects of sharing data whilst maintaining the educational utility of data sharing between tutors and students. To do so, we start by surveying the possible methods of sharing data, and we use this to design a token-based scheme for facilitating data sharing. We implemented our scheme and observed it in use by 7,798 students over the course of one year. We find that our proposed scheme provides a good balance between transparency, user control, educational utility and scalability.

Modern deep neural networks have achieved impressive results in a variety of automated tasks, such as text generation, grammar learning, and speech recognition. This paper discusses how education research might leverage recurrent neural network architectures in two small case studies. Specifically, we train a two-layer Long Short-Term Memory (LSTM) network on two distinct forms of education data: (1) essays written by students in a summative environment, and (2) MOOC clickstream data. Without any features specified beforehand, the network attempts to learn the underlying structure of the input sequences. After training, the model can be used generatively to produce new sequences with the same underlying patterns exhibited by the input distribution. These early explorations demonstrate the potential for applying deep learning techniques to large education data sets.

Professional learning is a critical component of the ongoing improvement, innovation and adoption of new practices that support learning at scale. In this context, educators must learn how to apply digital technologies and work effectively in digital networks. This study examines how higher education professionals adapted their practice to enable more open and flexible work processes. A case study carried out using Activity Theory showed that teams involved in the development of a module all need access to a range of expertise both practical and academic. At each stage, they need to be clear about the learning outcomes of the module, the responsibilities of each team and its constraints. Teams need to be willing to agree ways to shift those constraints in order to develop a module effectively.
