Learning Analytics (LA) dashboards aggregate indicators about student performance and demographics to support academic advising. The majority of existing dashboards are targeted at advisors and professors, but not much attention has been put into students’ need for information for their own academic decision-making. In this study, we identify relev...
Learning analytics (LA) can provide useful information for addressing the educational needs in Latin American universities, such as reducing program quality disparities and student dropout rates. Some researchers have suggested to build capacity in this region for institutional adoption of LA tools. Yet, there is still a long way to move from exper...
Despite the success of academic advising dashboards in several higher educational institutions (HEI), these dashboards are still under‐explored in Latin American HEI's. To close this gap, three different Latin American universities adapted an existing advising dashboard, originally deployed at the KU Leuven to their own context. In all three cases,...
This paper presents a case study on the adoption and the impact of new modules in a learning analytics dashboard supporting the dialogue between student advisors and students when advising on a study plan for the next academic semester in Escuela Superior Politecnica del Litoral, a higher education institute in Ecuador. The impact and the adoption...
Many Latin‐American institutions recognise the potential of learning analytics (LA). However, the number of actual LA implementations at scale remains limited, notwithstanding considerable effort made to formulate guidelines and frameworks to support the LA policy development. Guidance on how to coordinate the interaction between the LA policymakin...
Learning analytics dashboards are at the core of the LAK vision to involve the human into the decision-making process. The key focus of these dashboards is to support better human sense-making and decision-making by visualising data about learners to a variety of stakeholders. Early research on learning analytics dashboards focused on the use of vi...
Learning Analytics (LA) enables leaders to improve teaching, learning, organizational efficiency, and decision making. Nonetheless, LA initiatives often have difficulty to move out of prototype into real educational practice. As an emerging multidisciplinary field, we wonder how much its challenges are similar to other more mature related fields. T...
In this study, we present a case study involving two self-service dashboards providing feedback on learning and study skills and on academic achievement. These dashboards were offered to first-year university students in several study programmes in Flanders, Belgium. Data for this study were collected using usage tracking (N = 2875) and a survey ta...
To start medical or dentistry studies in Flanders, prospective students need to pass a central admission test. A blended program with four Small Private Online Courses (SPOCs) was designed to support those students. The logs from the platform provide an opportunity to delve into the learners’ interactions and to develop predictive models to forecas...
In learning by demonstration, the generalization of motion trajectories far away from the set of demonstrations is often limited by the dependency of the learned models on arbitrary coordinate references. Trajectory shape descriptors have the potential to remove these dependencies by representing demonstrated trajectories in a coordinate-free way....
When students enter higher education, they can encounter the feeling of unpreparedness. In fact, students who lack the appropriate prior education are less prepared. Therefore developing and implementing appropriate interventions for incoming students is important. This study examined the effectiveness of two new interventions at the Faculty of Eng...
A plethora of studies have shown that procrastination is associated with deleterious consequences. Recently, some authors argued that for some students, purposefully delaying tasks might be a beneficial strategy that is positively related with desired outcomes. To measure purposeful delay, the Active Procrastination Scale (APS), developed by Choi a...
Single‐best answers to multiple‐choice items are commonly dichotomized into correct and incorrect responses, and modeled using either a dichotomous item response theory (IRT) model or a polytomous one if differences among all response options are to be retained. The current study presents an alternative IRT‐based modeling approach to multiple‐choic...
From the perspective of Learning and Educational Technologies, academic advising has been one of the most overlooked aspects of academic support systems, despite being critical for the learning process and final success of students. The majority of higher education institutions provides simple technical support to academic advisers with basic descr...

First-year student success in Engineering Bachelor programs is well-studied. Both traditional statistical modelling and machine learning approaches have been used to study what makes students successful. While statistical modelling helps to obtain population-wide patterns, they often fail to create accurate predictions for individual students. Pred...
In recent years, Learning Analytics (LA) is finding more and more practical adoption, alongside of continued research interest. However, questions about the impact of LA applications and their underpinning in educational science are still being raised, impeding viability of some LA projects at larger scale. Within this paper we describe two example...
The demand for engineering graduates is so high that employers struggle to fill the vacancies [1], [2]. The number of engineering students is increasing and due to a more flexible higher education system even more students can gain access to an engineering program. Although it can be applauded that more students can enter higher education, the ques...
Learning Analytics has been widely developed in European countries. Latin America is also starting to measure and optimize teaching and learning processes through Learning Analytics. However, the existing attempts in this direction are very isolated. Further efforts are needed in order to promote greater sharing of best practices between regions. A...
This papers focuses on the use of learning dashboards in higher education to foster self-regulated learning and open education. Students in higher education have to evolve to independent and lifelong learners. Actionable feedback during learning that evokes critical self-reflection, helps to set learning goals, and strengthens self-regulation will...
Administering multiple-choice questions with correction for guessing fails to take into account partial knowledge and may introduce a bias as examinees may differ in risk-taking to guess the correct answer when not having full knowledge. In the latter case, elimination scoring gives examinees the opportunity to express their partial knowledge as th...

During a Delphi consensus study, a new joint gait classification system was developed for children with cerebral palsy (CP). This system, whose reliability and content validity have previously been established, identified 49 distinct joint patterns. The present study aims to provide a first insight toward the construct validity and clinical relevan...
Aim:
This study aimed to quantify the inter- and intrarater clinician agreement on joint motion patterns in children with spastic cerebral palsy (CP), which were recently specified by a Delphi consensus study. It also examined whether experience with three-dimensional gait analysis (3DGA) is a prerequisite for using the patterns.
Method:
The exp...
Experts recently identified 49 joint motion patterns in children with cerebral palsy during a Delphi consensus study. Pattern definitions were therefore the result of subjective expert opinion. The present study aims to provide objective, quantitative data supporting the identification of these consensus-based patterns. To do so, statistical parame...

The economic and financial crisis is having an important socio-economic effect in Europe and is threatening Europe’s economic growth model and employment and the sustainability of Europe’s welfare model. To counter the crisis, Europe should further evolve to a knowledge- driven and technology-based economy. This evolution however causes a rise in t...
Learning Analytics (LA) dashboards help raise student and teacher awareness regarding learner activities. In blog-supported and inquiry-based learning courses, LA data is not limited to student activities, but also contains an abundance of digital learner artefacts, such as blog posts, hypotheses, and mind-maps. Exploring peer activities and artefa...
Multiple-choice questions (MPQ) are considered an objective way for testing large groups, and allow for fast feedback. A drawback of MPQ is that students can gain marks by guessing, and that depending on the marking method personality traits such as risk aversion might influence the total score. A variety of marking methods for MPQ are available [1...
Entering a STEM study programme at university can be an overwhelming experience. Therefore several studies aimed at composing/implementing tests that focus on possible study success predictors. These tests can be a tool to select or help first-year students to position themselves before or at the beginning of the academic year. An optimized, non-bi...
Large interactive displays and surfaces are useful modalities for visualizing big multi-dimensional data sets. They can offer simultaneous views on different facets of the data which lead to an efficient and effective environment for data exploration and analysis. While every data analyst and enthusiast can benefit from these advantages, large inte...
We introduce a probabilistic language and an efficient inference algorithm based on distributional clauses for static and dynamic inference in hybrid relational domains. Static inference is based on sampling, where the samples represent (partial) worlds (with discrete and continuous variables). Furthermore, we use backward reasoning to determine wh...
