Concept Mapping ist eine Lernstrategie, die insbesondere das bedeutungsvolle Lernen unterstützt. Ziel dieser Studie war es, den Nutzen von kognitiven und/oder metakognitiven Prompts auf den Lernerfolg beim Lernen durch Concept Mapping zu untersuchen. Die teilnehmenden Schülerinnen und Schüler (N = 112, Durchschnittsalter: 17.20 Jahre) erzielten einen signifikant besseren Lernerfolg, wenn sie durch Prompts beim Anfertigen einer Concept Map unterstützt wurden. Gemischte Prompts waren dabei im Vergleich zu nur kognitiven bzw. nur metakognitiven Prompts nicht effektiver, offensichtlich regte bereits die Verfügbarkeit von Prompts die Lernenden zu systematischerem Lernverhalten an. Als Fazit dieser Studie lässt sich festhalten, dass Prompts als Hilfestellung bei der Anwendung einer neuen Lerntechnik sehr wohl positive Effekte haben. Eine Follow-Up-Messung ohne Prompts zeigte jedoch, dass die einmalige Unterstützung durch Prompts nicht ausreichte, um die Lerntechnik weiterhin selbstständig erfolgreich anzuwenden.

This research is motivated by the learning result of Social Sciences of Grade VI SD Negeri 022 Jaya Mukti KotaDumai which is still very low. This study aims to improve the learning outcomes of Social Sciences students.From the data analysis there is an increase of both teacher activity, student activity, and student learning result,that is teacher activity at meeting 1 cycle I percentage is 65% (enough) and at meeting 2 increase to 80%(good). In the second cycle of meeting 3 it increases again to 90% (very good) and at meeting 4 increases to95% (very good). Judging from the student activity also increased from the 1st meeting of cycle I was 60%(enough) and at meeting 2 increased to 70% (good). In the second cycle of meeting 3 it increased to 85% (verygood) and at the 4th meeting to 95% (very good). Judging from student learning outcomes, the average basicscore 63 increased to 75 in the first cycle of increase 12 points later in cycle II increased to 95 in cycle II largeincrease of 20 points. From the data analysis there is an increase both from teacher activity, student activity,and student learning outcomes. It can be concluded that the Improved Learning Model concept map can improvethe learning outcomes of IPS students of class VI SD Negeri 022 Jaya Mukti Kota Dumai.

AbstractProper treatment of prostate cancer is essential to increase the survival chance. In this sense, numerous studies show how important the communication between all stakeholders in the clinic is. This communication is difficult because of the lack of conventions while referring to the location where a biopsy for diagnosis was taken. This becomes even more challenging taking into account that experts of different fields work on the data and have different requirements. In this paper a web-based communication tool is proposed that incorporates a visualization of the prostate divided into 27 segments according to the PI-RADS protocol. The tool provides 2 working modes that consider the requirements of radiologist and pathologist while keeping it consistent. The tool comprises all relevant information given by pathologists and radiologists, such as, severity grades of the disease or tumor length. Everything is visualized using a colour code for better undestanding.

In recent years, many tools have been developed to understand attacks that make use of visualization, but few examples aims to predict real-world consequences. We have developed a visualization tool that aims to improve decision support during attacks. Our tool visualizes propagation of risks from IDS and AV-alert data by relating sensor alerts to Business Process (BP) tasks and machine assets: an important capability gap present in many Security Operation Centres (SOCs) today. In this paper we present a user study in which we evaluate the tool's usability and ability to deliver situational awareness to the analyst. Ten analysts from seven SOCs performed carefully designed tasks related to understanding risks and prioritising recovery decisions. The study was conducted in laboratory conditions, with simulated attacks, and used a mixed-method approach to collect data from questionnaires, eyetracking and voice-recorded interviews. The findings suggest that providing analysts with situational awareness relating to business priorities can help them prioritise response strategies. Finally, we provide an in-depth discussion on the wider questions related to user studies in similar conditions as well as lessons learned from our user study and developing a visualization tool of this type.
