A Paperless Environment for Annotating and Marking Student Assignment
1Annotating Digital DocumentsL3
3Ink Annotations are different to text annotationsInk stands out from the originalIt is free form the annotator canEmphasize underline, highlight, asteriskQuestionAgreeAdd side notes to explain, clarifyThe authorship remains with the original author 34Why do we annotate?Active readingAdding annotations to a document helps the reader to process the informationCommunicate with others/selfWhen developing the document collaborativelyWhen evaluating the work (eg marking assignments)45Expressiveness and usefulnessAnnotations are very individualisticHowever they can generally be understood by others.
Interesting studies of students choosing old already annotated books and looking carefully at the style of annotationsAlso students understanding pre-annotated material more quickly than the original document56Visual message Looking at an annotated document in an instant you understand the position of the annotator. Are they:Being critical?Correcting the spelling and grammar?Adding their own explanatory notes67Example SoftwarePenmarkedAssignment markingRCACode review78Penmarked MotivationElectronic submission and marking of assignments is attractive to faculty and students alike Particularly programs assignments when a digital copy of the assignment is required for markingHowever providing meaningful feedback to students is more difficult And individualised feedback is important
89Design BriefAnnotation of the scriptScore recordingWork practice supportWho wants to waste time marking?910Implementation
1011Annotation PaneInk anywhereEraseMultiple files
A technical nightmare!Two layersLots of Windows API callsWe have more-or-less got pdf going
1112Scoring PaneMarking rubricNumeric scoresEntered in score box with pen and recognized using Microsoft recognition engine with numeric factoid feature also range checkedOr through the keyboard
1213Work Practices SupportPre-markingSet up of marking rubric, directories, file type/name filtersCollection of assignments from a dropbox or directory structureDuringAll assignments listed in student list paneCan be marked as opened and completeAutomatic unpackaging of zip filesDirect link to students folder for executing programOn completion Exporting of marks as xml fileConversion of assignments to pdf files (includes mark rubric and annotated files)Email return of assignment to student
1314Evaluation 1Iterative informal during developmentUsability testing with think aloudTalking while marking a program is challengingA few interaction problems pen/keyboard inputdo you want to save dialogueRecognition required correct formation of digitsUsing the pen to interact with non-tablet programs (the students assignments) is slow!Focus groupStudent list and workflow support invaluableAccurate writing required for score recognition 14Evaluation 2One large programming class ~ 180 studentsSix markersThree assignments increasing and size and complexityThree treatmentsPaperDatabasePenmarked Balanced treatmentEach student had one assignment marked by each processEach marker used each process Rotated so student marker different for each assignment

(statistically significant)Overall PreferenceOverall preference for PenmarkedWhat else we could do with digital inkIDEs
22RCAOne of the difficulties with Penmarked is that the markers have to go to another application to compile and execute the program RCA is an annotation addin for Visual Studio2223RCA in Visual Studio

No extensibility points from the code windows!25CodeAnnotator UI26

2930DiscussionWhy is it so difficult?There is a fundamental digital divide between text and imagesTrying to combine the two and keep them consistent is really difficultKnowing what to do with ink when the underlying document changes its problematicMany standard windows do not easily support non-text3031Future WorkVisual studio 2010Yeah it works!
