  13. Observing Frequency/Proportion Available: WCBA 2010

  14. Observing Frequency/Proportion What Proportion Told Us What Proportion Doesn’t Tell Us Which students used multiple tools If tools were used in some sections more than others When and for how long each tool was used The impact of tool use on performance Exploration vs. need • All tools were triggered at least once by a higher percentage of 8th graders than 12thgraders • Text-to-Speech and scrolling were used by a greater percentage of students than other system tools • Help was used by a smaller proportion of students than other system tools

  15. What Can We Observe? Easy • Frequency/Proportion (event ID, booklet ID, total number of participants) • End State (event ID, booklet ID, order of events) • Time Course (event ID, time stamp) • Duration/Intervals (event ID, 2 time stamps, math) • Qualitative (event ID, extended data) • Big Picture Qualitative (all data, other data sources) Difficult

  16. Observing End State Available: WCBA 2010 Grade 8 Blue–72% High Contrast–21% Gray–7%

  17. Observing End State What End State Told Us What End State Doesn’t Tell Us When they changed to the final state (beginning? end?) How long they spent in the end state Why they changed How many blue users surveyed the other skins first (i.e., kept the default vs. choosing it) • Blue was the end state skin for 72% of participants • Grey was the least used (7%)

  18. What Can We Observe? Easy • Frequency/Proportion (event ID, booklet ID, total number of participants) • End State (event ID, booklet ID, order of events) • Time Course (event ID, time stamp) • Duration/Intervals (event ID, 2 time stamps, math) • Qualitative (event ID, extended data) • Big Picture Qualitative (all data, other data sources) Difficult

  19. Available: MCBA 2011 Observing Time Course Booklet #6037

  20. Observing Time Course What Time Course Told Us What Time Course Doesn’t Tell Us Which words were misspelled Number of words that were not identified as misspelled If spellcheck was used to good effect What was happening in between spellcheck events • When Corrected Misspelling events occurred • How long between Corrected Misspelling events

  21. What Can We Observe? Easy • Frequency/Proportion (event ID, booklet ID, total number of participants) • End State (event ID, booklet ID, order of events) • Time Course (event ID, time stamp) • Duration/Intervals (event ID, 2 time stamps, math) • Qualitative (event ID, extended data) • Big Picture Qualitative (all data, other data sources) Difficult

  22. Duration(2 time stamps, math) Observing Duration/Intervals

  23. Duration(2 time stamps, math) Observing Duration/Intervals • YOU ARE PERMITTED TO USE A CALCULATOR IN THIS SECTION. • This section has 16 questions. Respond to questions on the computer. You will have to select an answer or type your response as directed. In those questions where you type an answer, it is important that your answer be clear and complete since partial credit may be awarded. • Remember: • You are permitted to use a calculator in this section; either your own, or the one provided by NAEP. If you need help using the one provided by NAEP, read the instructions on the back of the scratch paper or look at the quick reference card on the calculator lid. • If the calculator does not work or you do not know how to use it, raise your hand and ask for help. • You will have to decide when to use the calculator. For some questions using the calculator is helpful, and may even be necessary. However, for other questions the calculator may not be helpful. • This section is 25 minutes. If you finish before time is up, you may review any question within this section. You will not be able to go to the next section until 25 minutes are up. • You may use the scratch paper provided, but be sure to enter all of your responses on the computer. • Click NEXT to continue.

  25. Observing Duration/Intervals What Duration Tells Us What Duration Doesn’t Tell Us What students were doing while on that page How much of the directions they read How well they understood the directions • Students spent from 15-20 seconds on the directions for different blocks • Students on average spent more time on the directions for VE521278c16 • Senior Usability Experts are really slow readers!

  26. What Can We Observe? • Frequency/Proportion (event ID, booklet ID, total number of participants) • End State (event ID, booklet ID, order of events) • Time Course (event ID, time stamp) • Duration/Intervals (event ID, 2 time stamps, math) • Qualitative (event ID, extended data) • Big Picture Qualitative (all data, other data sources) Easy Difficult

  27. Observing Qualitative Information • Spelling Examples (includes punctuation) • “befor” vs. “before” • “ninjas” vs. “ninja’s” • Spacing Examples • “monkey.You” vs. “monkey. You” • “books,none” vs. “books, none” • No Correction Examples • “stonger,faster,and” (no alternate spelling suggested) • “orrhjrejfjhhrhgjshjdnewjmfnffjnendndsmsandbfnnwnnfgbnemsnfcnfnsehgfnbsjehdnbvfndbfjxdnnebndfnfbfbfbbdbdnbsnsnnnsnsnsnnssnsnnsnnsnssssssssdjejkwjennbrbbfbbfbfcbfcbcvbbcxbcxblolooooooooooooooooooooooobbxbbx” Identified Error Types

  28. Observing Qualitative Information What Qualitative Told Us What It Didn’t Tell Us The impact of the modification on the final output Re-creation of the final product • What was modified • How it was modified • When it was modified

  29. Outline • What are observable data? • What can we observe in the data? • How have we used what we’ve observed? • How can we observe more?

  30. Major Takeaways • Students used accommodations and system and WP tools substantially during CBAs. • Scrolling: 60%-70% • Text-to-Speech: 53%-72%

  31. Major Takeaways • Some accommodations and tools were not used as might be expected • Accommodation – Directions written in Spanish • Used by - 55%-56% of eligible students

  32. Major Takeaways Observable data helped to identify and validate usability issues with CBAs. • Misuse of Next button • To open writing panel • To check on time remaining • Pausing tutorials (only 8%-9% of pausers didn’t finish) • Scrolling was not used by 7%-14% of participants on items where it was necessary in order to show all the information.

  33. Major Takeaways • Insight into student response patterns • Number of words used for different writing purposes

  34. Major Takeaways • Insight into student response patterns • Types of errors identified by spell check

  35. Major Takeaways • Insight into student response patterns • Distribution of spellcheck corrections by student

  36. Major Takeaways • Insight into student response patterns • Compare silent reading rates

  38. Written Instructions? • Written instructions are not being read for comprehension • Possible Causes / Consequences • The students suffered for not having read the instructions • The students didn’t need the instructions • Some students didn’t need the instructions and skewed the average duration data

  39. What Do We Know? • How students use system tools • How students use word processing tools • What keys they are pressing and when • What buttons they are clicking and when • What words are identified by spell check, which are corrected and how they are corrected • How much time students spend on each screen

  40. Outline • What are observable data? • What can we observe in the data? • How have we used what we’ve observed? • How can we observe more?

  41. Descriptive vs. Experimental • Observable Data are by definition descriptive • Don’t answer causation or other complex questions • Causation needs experimental data • Isolate variables • Manipulate conditions • Compare groups • Complex questions • Pair Observable Data with other information

  42. The More You Know, The Less You Know • Simple Question: Can Students Access the Features of CBA? • Simple Answer: Yes • Complex Questions • Did the changes made to interface have any impact on their performance or comfort during assessment? • Did everyone who would have benefited use them? • Do kids even know what benefits them? • What is impact of age/grade on beneficial impact of interface changes?

  43. More Questions • Why do some students not use system tools? • Why do some students not use word processing tools? • Which tools result in better performance? • Are there other tools that might prove beneficial? • Do written instructions help? Everyone?

  44. Better Questions = Better Answers • Start with questions to be answered • Determine sources of information necessary to answer question (research design) • Obs. Data (OD) + Usability testing • OD + Background Question Answers • OD + Performance Scores • OD + Qualitative Analyses • Interpret interactions among data

  45. Data Sources • Observable Data (behavior) • Easy to collect (now) • Every participant (not just a sample) • Many, many parameters (many, many) • Single source • Profile Data (outcomes, background) • Also easy to collect on every participant • Fewer parameters • Multiple sources • Qualitative Data (impact, usability) • Requires interpretation • Difficult to collect • Requires sampling (research design)

  46. Data: The Final Frontier Level III – Meaning Multiple variables Interactions among variables Qualitative information Level II – Structure Extended information Time course / Duration Value Level I – Counting Single variable Frequency /Proportion Value
