Providing feedback on programming assignments is a tedious task for the instructor, and even impossible in large MOOCs with thousands of students. In this paper, we present a novel technique for automatic feedback generation: (1) For a given programming assignment, we automatically cluster the correct student attempts based on their underlying strategy. From each class we select one student att...

Since 2012, the vision of MOOCs in universities has been evolving rapidly. Universities that have decided to place a serious bet for including this kind of courses in their portfolio have involved a diverse set of staff roles within the institution. In most cases, with the exception of fully dedicated staff members hired for the sole purpose of MOOC development, MOOC related tasks are assigned ...

Massive Open Online Courses (MOOC) are becoming increasingly difficult to ignore in online education. Recent developments in MOOC have heightened the need for understanding the MOOC. The issue of an in-depth understanding of the MOOC setting has been a key subject within the field of qualitative research. However, far too little attention has been paid to the MOOC setting. This paper seeks to p...

The existence of soliton solutions is one of the main features of nonlinear wave models solvable by means of the inverse scattering method. Each of these models has associated a particular type of soliton; however, solitons always share a series of common properties: they behave as classical particles and their scattering processes may be interpreted as a succession of paired collisions in whic...

Although testing is critical in GSD, its application in this context has not been deeply investigated so far. This work investigates testing in GSD. It provides support for test managers acting in a globally distributed environment. With this it closes a gap. The leading question is ”What problems exist in testing in GSD and how can they be addressed in projects?”. Decomposing this question we ...

Previous studies about engagement in MOOCs has focused primarily on behavioral engagement and less attention has been paid to cognitive engagement. This may lead to incomplete or even incorrect understandings about students experience and learning in MOOCs. In this study, we use number of lectures watched as a proxy for behavioral engagement and number of pauses in lectures watched as a proxy f...

Ziel des Beitrags ist, einen Überblick über aktuelle Entwicklungen und Ausprägungen von MOOCs sowie die Erfahrungen und Ergebnisse aus der Untersuchung von zwei MOOCs vorzustellen, die 2011 und 2012 durchgeführt wurden. Besondere Schwerpunkte liegen dabei auf der Bedeutung und Ausprägung der Beteiligungsformen in den verschiedenen MOOC-Formaten, der Beteiligung in den beiden untersuchten MOOCs ...

background: massive ischemic stroke causes significant mortality and morbidity in stroke patients. the main treatments for massive ischemic stroke are recombinant tissue plasminogen activator (rtpa), craniotomy, and endovascular interventions. due to destructive  effects  of   bradykinin  on  the  nervous system in ischemic stroke, it seems reasonable that using noscapine as a bradykinin antago...

the article reports a clinical case of a 39-year-old male patient who was admitted in the emergency room in shock. the clinical exams and additional tests identified a right massive hemothorax, without apparent etiological factors. he was submitted to an emergency right thoracotomy. a bulky varicose formation in the diaphragmatic surface, with evident laceration and haemorrhage was identified. ...

the trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. a very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. these elements may be concentrated in non-magnetic and magnetic part of calcrete. based on the current research, mineralogica...
