5. Introduction
• Children write their own blogs
• Checked by teachers and an intelligent
dictionary
• Many exercises
• Monitoring learning process not possible
• Exercises are on different servers (eg. learningapps.org)

6. Goals
• Monitor learning process
• Help and motivate children
• Find out what can be learned from user data
• How do children react and like the exercises
(evaluation)
• Help teachers to create more (better) exercises

27. Evaluation and Data Analysis
October 31, 2019 27

28. Evaluation
• Field Test in "Praxisvolksschule PH Steiermark"
• 3rd grade school class
• 21 children (11 girls, 10 boys)
• 15 PCs
• Anonymous (Test Accounts)
• Duration 1.5h
• 4 exercises only
• Questionnaire with 4 statements to be rated by the
kids for each exercise
October 31, 2019 28

29. Questionnaire
1. I knew what the task was
2. I could solve the task myself
3. It was fun to practice
4. I also want to do the exercise at home

31. Data Analysis
• Einsetzen
• Most mistakes because of inaccurate description and
typing errors
• Using past tense instead of present tense
• Some kids knew how to write the word, but added a
white space character
• Fehlerstellen
• Some kids didn‘t take this exercise serious (clicking on
every word until error was found)
• Word „Blüte“ (blossom) clicked 21 times in total (20
times by the same user)
October 31, 2019 31

32. Data Analysis
• Merkwörter (Leicht)
• Although not clear in beginning what to do, only a few
typical typing errors
• Merkwörter (Schwer)
• Many mistakes, lots of empty input fields
• Average error rate: 71.5%
• Not a single session was error free
• Zuordnen (Drag & Drop)
• Average error rate: 21.1%
October 31, 2019 32

33. Summary
• Despite little time well received by children
• Descriptions for every exercise is essential for
success
• Immediate and visual feedback important
• Fehlerstellen: Kids thought exercise is finished
• Young children are rather slow at typing
• Should be considered when analysing data
October 31, 2019 33

34. Future Work
• Improve current exercises (Usability!)
• More exercises
• API provides access to data
• Making exercises available on mobile devices
• Tablets
• Smartphones
