Peer assessment based assignment to enhance interactions in online learning groups

2015

In this paper, we report on the findings from our PhD work on how peer assessment based assignment method can enhance interaction in online learning groups. The method is explored and tried out on the research methods course on the Bachelor of Commerce Programme which is run in distance learning mode at Makerere University. Based on the idea that learning groups can enhance effective learning in online learning environments, we used the affordance eLearning framework to design the peer assessment based assignment task and then qualitative methods collect and report on data. The results reveal that there was increased interaction through peer feedback. Students were motivated because of the …

Adaptive formative feedback to improve strategic search decisions in task-oriented reading

2014

This study analyses the effectiveness of adaptive formative feedback to boost strategic search decisions and performance when students are asked to answer a set of questions in a task-oriented reading situation. We compared automatic feedback that included information about the right answer with feedback that also included the connection between the students' strategic search decisions and their performance. Ninety-two high school students read two non-continuous texts. They received feedback during a training phase, and then they read and also received feedback with a similar text in a final phase. Text and questions were presented using a new computer-based technology that provided automa…

Exploiting social comparison using pervasive displays and mobile notifications for reducing energy consumption

2017

Abstract Public displays have been used as a persuasive technology in many prior works. In this paper, we describe a persuasive pervasive system aimed at influencing users’ behavior for reducing energy consumption in buildings. This system exploits a pervasive display that visualizes the energy consumption in different levels (rooms, floors, and buildings), exploiting social comparison techniques. Moreover, our system may be extended by means of a mobile application that sends persuasive personalized messages to the users regarding their energy consumption. We then present our evaluation study design, aimed at comparing the effectiveness of three possible implementation of our system: one b…

Compressive single-pixel multispectral Stokes polarimeter

2014

We present a single-pixel system that performs polarimetric multispectral imaging with the aid of compressive sensing techniques. We experimentally obtain the full Stokes spatial distribution of a scene for different spectral channels.

Developing MLS Location-Based Service Pilot System

2002

Development of mobile networks and terminals provides basis for advanced mobile services and applications. One of the new features is support for locating the mobile user by her/his terminal. The Location-Based Services (LBS), utilising this feature, are expected to form an important class of the new services. At the Information Technology Research Institute, University of Jyvaskyla, LBSs have been studied in MultiMeetMobile research project. The project developed an LBS pilot system, called MLS. This paper presents the experiences collected during the development of the LBS pilot and describes the MLS system.

Improving SIFT-based descriptors stability to rotations

2010

Image descriptors are widely adopted structures to match image features. SIFT-based descriptors are collections of gradient orientation histograms computed on different feature regions, commonly divided by using a regular Cartesian grid or a log-polar grid. In order to achieve rotation invariance, feature patches have to be generally rotated in the direction of the dominant gradient orientation. In this paper we present a modification of the GLOH descriptor, a SIFT-based descriptor based on a log-polar grid, which avoids to rotate the feature patch before computing the descriptor since predefined discrete orientations can be easily derived by shifting the descriptor vector. The proposed des…
