1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.
2. If their phone camera doesn't automatically detect and decode QR codes, ask students to
4. Cut them out and place them around your class / school.
1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.
2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.
3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!
4. A detailed case study in how to set up a successful QR Scavenger Hunt using this tool can be found here.
Question | Answer |
| 1. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. Mr. Goldberg, a kindergarten teacher, has recently compared his observation-based classroom assessments with the recently state-approved Content Standards for Kindergartners. He discovered that fully five of the new content standards are not even addressed in his observation-based assessments. Accordingly, he decides to alter his observation instrument so all of the new state-sanctioned kindergarten content standards will be represented by his classroom tests. Was Mr. Goldberg's decision right or wrong? | Right | 2. | 3. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. Mr. Acura has persuaded a colleague to administer Mr. Acura's seventh-grade science test to the colleague's seventh-grade social studies students (who have not yet taken a science class). Mr. Acura, who wants his classroom assessments to yield criterion-referenced interpretations about his students, is delighted to learn that in the item-by-item comparisons between the "instructed" science students and the "uninstructed" social studies students, Mr. Acura's science students dramatically out-perform their social studies counterparts. Mr. Acura decides to leave his tests largely unaltered. Was Mr. Acura's decision right or wrong? | Right | 4. | 5. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. A sixth-grade teacher, Mrs. Jones, has subjected her major tests (which she hopes will yield accurate criterion-referenced inferences) to a pretest-posttest type of item analysis. Because she discovers that almost all of her items reflect substantial pre-to-post increases in the number of students' correct responses, Mrs. Jones decides to make about half of her items more difficult so students' pre-to-post improvements will not be so pronounced. Was Mrs. Jones' decision right or wrong? | Wrong | 6. | 7. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. Mr. Hubbart, a science teacher, reviews the content of his own tests he created two years ago. He discovers the content in a half-dozen items has been rendered inaccurate by recent studies published in scientific research journals. Without checking with any colleagues, he decides to revise the half-dozen items so that they are consistent with the latest research findings. Was Mr. Hubbart's decision right or wrong? | Right | 8. | 9. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. Mr. Robinson decides to eliminate all items from his pretest on which students score too well. He plans to eliminate most subsequent instruction dealing with the content represented by those items. He finds that four of his pretest's items have p values of .20 or less. As a result, he decides to replace each of these easy items with more difficult ones. Was Mr. Robinson's decision right or wrong? | Wrong | 10. | 11. Directions: Please read each of the following descriptions of classroom teachers who are deciding whether to revise items from their classroom tests. For each description, indicate whether the described teacher made the Right decision or the Wrong decision. Mr. Villa uses one of his chemistry tests to discriminate among students so the most able students can take part in a special competition sponsored by the National Science Foundation. A testing specialist at the school district's office has performed several analyses on Mr. Villa's items indicating at least a fourth of the items on this test have discrimination indices of less than .15. Seeing these results, Mr. Villa decides to alter those items so they might discriminate more efficiently. Was Mr. Villa's decision right or wrong? | Right |
