(This is actually a common point of debate between colleagues in my department; some of whom want all-MC tests all the time.)

My problem ...Thank you Daniel for pointing me here. My problem arose under like circumstances as the ones leading you to write this blog entry. My test was multiple choice as well, thus students had no chance to document which prcedure the followed to the result. This is often a caveat in MC tests, as you often need to assess students' ability to process a problem - rather than their ability to conjure a right answer.Morten Engelsmannhttps://www.blogger.com/profile/10518437210045037586noreply@blogger.comtag:blogger.com,1999:blog-7718462793516968883.post-30680952088302594592017-05-25T11:25:44.644-04:002017-05-25T11:25:44.644-04:00Useful, thank you Daniel for pointing me here (fro...Useful, thank you Daniel for pointing me here (from [https://matheducators.stackexchange.com/q/12368/3502])Morten Engelsmannhttps://www.blogger.com/profile/10518437210045037586noreply@blogger.comtag:blogger.com,1999:blog-7718462793516968883.post-61522038126466390712010-06-20T21:01:49.428-04:002010-06-20T21:01:49.428-04:00I just finished a summer 2-week class on teaching ...I just finished a summer 2-week class on teaching number sense and we all agreed that detecting these "things that shouldn't work" issues requires absolute ninja number sense on the part of the teacher. My favorite was when the problem (either from the text or my own misguided brain) would lead students to 2 twos and a four, leaving students to guess if the twos were added, multiplied, or if two was squared.Raymond Johnsonhttps://www.blogger.com/profile/14213559862857292867noreply@blogger.com
