The specific goal of this case study was to test the educational benefits and usability of the Web-Trace software application, and of a mobile tablet PC with the digital pen. The particular focus of the research was the cephalometry study module, arranged at the Helsinki University during the Spring 2007. The objects of the study were 12 dental students. The study sought to combine qualitative and quantitative approaches within an ethnographic research design. Data were collected using a network-based questionnaire. In addition, 11 students were interviewed. The data will be analyzed by using content analysis and statistical analyses. This article explores background of the study and highlights some preliminary findings of the research.","PeriodicalId":408508,"journal":{"name":"First International Workshop on Pen-Based Learning Technologies (PLT 2007)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127865105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper architecture is unified software architecture that allows the use of several types of electronic pen and paper devices without having to modify the main application. Electronic ink written by students in exams is captured, transformed into a standard format and then sent to the paper architecture server. There the ink is segmented and processed. We have taken a hybrid approach for the scoring application. Selection type questions are automatically recognized and scored. For free text questions we have developed an interface that allows teachers to mark them interactively. It provides question reorganization, empty questions marking, and other techniques to reduce the scoring time. A preliminary evaluation comparing the exams scoring by using the application and by hand showed considerable reduction of the scoring time.","PeriodicalId":408508,"journal":{"name":"First International Workshop on Pen-Based Learning Technologies (PLT 2007)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130343811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three important types of learning conversations: the Why learn, the what is this, and the How better to learn this conversations are considered. Important \"teachable moments\" occur during problem solving and theory development, which are best dealt with by ad-hoc diagrammatic explanation. This is particularly true when synchronous 'e-learning' conversations in advanced topics are concerned. Pen-tablet interfaces allow for much greater flexibility and richness under such circumstances. They also allow for valuable personal idiosyncrasies in the free development of mathematical notations.","PeriodicalId":408508,"journal":{"name":"First International Workshop on Pen-Based Learning Technologies (PLT 2007)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129114880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We believe one way to boost the utility of such simulations and animations is to make them easier to use. In this paper, we describe a pen-based interface for constructing weighted and unweighted graphs which functions as a front-end to shortest path and minimum spanning tree (MST) algorithm simulators that we have developed. We compare the usability of this pen-based interface to that of a WIMP-based interface and a hybrid interface that uses a mixture of pen-based and WIMP-based input methods. We report evaluation results on the usability of the three types of interfaces that we have developed. Our results show that a purely pen-based approach to graph creation may actually suffer from the relatively higher misrecognition rates of the harder-to-recognize symbols and inhibit usability. We conclude that a hybrid approach which combines a soft-keyboard with graph recognition outperforms interfaces that are purely pen-based or WIMP-based.","PeriodicalId":408508,"journal":{"name":"First International Workshop on Pen-Based Learning Technologies (PLT 2007)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power of a PC can be used to store a large amount of data, run specialized software, interact with a larger screen that allows student to sketch and write his/her interpretations and sharing them with the other people (students and teachers). The \"interpretation path\" can be more easily reconstructed and the uncertainties of the final synthetic map can be better estimated. The last generations of students demonstrate a more natural approach to those techniques then \"old- rugged\" geologists and field surveyors.

We show that, in addition to their usefulness for representing spatial relationships, drawing activities also display important interactional functions. A short 12 minute interaction is described in which a rich variety of shared drawing spaces are created. We make three claims: i) unlike gesture or speech, drawing activities do not automatically claim rights to the floor', ii) drawing sub-spaces are used to help people monitor if they are talking about the same thing iii) people collaborate to create 3D 'virtual' maquettes through temporary combinations of sketch spaces and gestures. We argue that drawing is defined more by its interactional than its inscriptional character.","PeriodicalId":408508,"journal":{"name":"First International Workshop on Pen-Based Learning Technologies (PLT 2007)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125693400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
