The effects of collaboration scripts on the number and quality of student interactions in a social annotation tool

[EN] Social Annotation (SA) tools can be used to facilitate active and collaborative learning when students have to study academic texts. However, making these tools available does not ensure students participate in argumentative discussions. Scaffolding students by means of collaborations scripts geared towards collaboration and discussion encourages students to engage in meaningful, high-quality interactions. We conducted an experiment with students (n=59) in a course running at a Dutch university, using the SA tool Perusall. A control group received normal instructions, while an experimental group received scaffolding through collaboration scripts. The results showed a significant increase in the number of responses to fellow students for the experimental group compared to the control group. The quality of the annotations, measured on levels of Bloom’s taxonomy, increased significantly for the experimental group compared to both its baseline measurement and the control group. However, when scaffolding was faded out over subsequent assignments these differences became non-significant. The experimental groups’ increased quality of annotations did not remain over time, suggesting that internalization of the scripts was not achieved.De Boer, V.; Spoelstra, H. (2021).

Innovatieprocessen voor een zorgvuldige intensieve veehouderij

Dit essay wil ten eerste een bijdrage zijn voor de discussie over een 'zorgvuldige intensieve' veehouderij en richt zich dan vooral op de aard van het onderzoek dat daar voor nodig is. Ten tweede is het bedoeld als een bijdrage voor het strategisch plan van het Wageningen UR Livestock Research en met name voor vormgeving van het speerpunt van de afdeling Innovatieprocessen. De auteurs nemen de verzelfstandiging van het landbouwkundig onderzoek en het gedachtegoed over van Ulrich Beck als basis voor het duiden van een kentering in enerzijds het organiseren van toepassingsgericht onderzoek en anderzijds het uitvoeren van onderzoek voor een duurzame ontwikkeling

Patients admitted to an intensive care unit after cardiac arrest often suffer from severe brain injury. This injury worsens further after restoration of circulation due to the cascade of reactions in the brain. Neuroprotective therapies aim to diminish this secondary brain injury, thereby targeting at a better outcome. Several new large international studies will start soon, next to two smaller national phase II studies. In this paper we describe the new studies and invite Dutch intensive care units to join

Effective Team Learning in the Cloud

Learning in the cloud can be a lonely activity for self-directing and self-organizing learners. Lack of sustained learner motivation can lead to less effective, less bond-creating learning experiences. By providing collaborative project-based learning opportunities these shortcomings can be overcome. A service design is introduced for the onset of collaborative project-based learning and team formation in the cloud, based on learning materials in the cloud, project definitions and characteristics, and learner ‘knowledge’, ‘personality’ and ‘preferences’. The article specifies how the data required by the design can be gathered. Team formations rules are deduced from existing team formation research. They steer the team formation process towards facilitating learning, creative problem solving or increased productivity outcomes. The rules are implemented in three team formation equations. Deployment of the equations on a set of test data demonstrates the effectiveness of the team formation service

A Study on SPICE Modeling of Non-Resonant Plasmonic Terahertz Detector

Department Of Electrical EngineeringThe terahertz (sub-millimeter wave) is the frequency resource, ranging from 100 GHz ~ 10 THz band, located in the middle region of the infrared and millimeter waves in the electromagnetic spectrum. Terahertz waves has unique physical characteristics, which is transparency of radio waves and straightness of light waves, simultaneously. The terahertz wave is applied to the basic science, such as device, spectroscopy, and imaging technology. And also adjust in the applied science, such as biomedical engineering, security, environment, information and communication. Which importance already verified. In the new shape of future market is expected to be formed broadly. For this application, operating in the THz frequency detecting device essential. Recently, Current elements operating in terahertz are present, such as compound semiconductor (???-???HBT, HEMT). But, there are disadvantage to use as a high price. Therefore, research have been made of silicon based THz detector in many research groups. Silicon-based nano-technology utilizes a plasma wave transistor technology. Which is using the space-time change of the channel charge density. That causes plasma wave oscillation in the MOSFET (Metal oxide semiconductor field effect transistor) channel and this effect available MOSET operating terahertz regime beyond MOSFET cut-off frequency. So, PWT (plasma wave transistor) is available terahertz detection and oscillation. For integrated possible post processing circuit development in these of terahertz applications system, silicon based PWT compact model is essential thing. For this compact model for spice simulation beyond cut-off frequency, we consider charge time variance model which is NQS (non-quasi-static) model, not quasi-static model. For NQS model two kinds of model exist, first is RC ladder model. That is seral connect MOSFET get rid of parasitic elements. And these complex circuit making the equivalent circuit model, it called New Elmore model. For post processing circuit simulation, fast simulation speed is essential, RC ladder model has a disadvantage (for simulating each segment). In this thesis we using New Elmore model based on Non-resonant plasmonic THz detector modeling, And verified physical validity of our NQS model using the our TCAD model based on Quasi-plasma 2DEG. And we propose fast and accurate compact modelingope

The Large-Scale Polarization of the Microwave Foreground

Most of the useful information about inflationary gravitational waves and reionization is on large angular scales where Galactic foreground contamination is the worst, so a key challenge is to model, quantify and remove polarized foregrounds. We use the Leiden radio surveys to quantify the polarized synchrotron radiation at large angular scales, which is likely to be the most challenging polarized contaminant for the WMAP satellite. We find that the synchrotron E- and B-contributions are equal to within 10% from 408-820MHz with a hint of E-domination at higher frequencies. We quantify Faraday Rotation & Depolarization effects and show that they cause the synchrotron polarization percentage to drop both towards lower frequencies and towards lower multipoles.Comment: To be published in the proceedings of "The Cosmic Microwave Background and its Polarization", New Astronomy Reviews, (eds.

The Ku-band Polarization Identifier

The Ku-band Polarization Identifier (KUPID) will integrate a very low noise 12-18 GHz, correlation polarimeter onto the Crawford Hill seven meter, millimeter-wave antenna. The primary components of the polarimeter will be built at the University of Miami and other key components, including the microwave horn and data acquisition system will be built at the University of Chicago and Princeton University. This project will measure the Q and U Stokes parameters in regions near the north celestial pole, in regions of low galactic contamination, and in regions near the galactic plane. The KUPID survey experiment makes use of many of the techniques employed in the Princeton IQU Experiment (PIQUE) that was developed by the members of this collaboration to detect CMB polarization at shorter wavelengths. The KUPID experiment will be constructed in parallel and on the same timescale as the CAPMAP experiment (see Barkats, this volume) which is the follow-on experiment to PIQUE. KUPID will observe on the Crawford Hill antenna from late spring until early autumn, while CAPMAP will observe during the lower water vapor months of late autumn until early spring.Comment: To be published in the proceedings of "The Cosmic Microwave Background and its Polarization", New Astronomy Reviews, (eds.

Properties of the warm magnetized ISM, as inferred from WSRT polarimetric imaging

We describe a first attempt to derive properties of the regular and turbulent Galactic magnetic field from multi-frequency polarimetric observations of the diffuse Galactic synchrotron background. A single-cell-size model of the thin Galactic disk is constructed which includes random and regular magnetic fields and thermal and relativistic electrons. The disk is irradiated from behind with a uniform partially polarized background. Radiation from the background and from the thin disk is Faraday rotated and depolarized while propagating through the medium. The model parameters are estimated from a comparison with 350 MHz observations in two regions at intermediate latitudes done with the Westerbork Synthesis Radio Telescope. We obtain good consistency between the estimates for the random and regular magnetic field strengths and typical scales of structure in the two regions. The regular magnetic field strength found is a few microGauss, and the ratio of random to regular magnetic field strength is 0.7 +/- 0.5, for a typical scale of the random component of 15 +/- 10 pc. Furthermore, the regular magnetic field is directed almost perpendicular to the line of sight. This modeling is a potentially powerful method to estimate the structure of the Galactic magnetic field, especially when more polarimetric observations of the diffuse synchrotron background at intermediate latitudes become available.Comment: 12 pages, 6 figures, accepted by A&
