Here are two lessons on interviewing witnesses (cognitive interview) and suspects (ethical interview). Each lesson assumes you have set advance reading from whichever textbook or other source you are using. Lesson one starts with students making comparisons between standard police interviews and cognitive interviews using this visible thinking routine for comparing. The main application activity is to write a letter to a chief constable persuading her to adopt cognitive interviewing in her force. I’ve found that some students get all up tight about writing an essay because it smells like assessment and they do a better job if they write a letter instead, even though the same skills are required. The slideshow gives a structure for the lesson.
Lesson two starts with the use of the same VTR. This is followed by an analysis task using this recording of a police suspect interview. Finally, students work up an evaluation using a handout of evidence. A slideshow structures the lesson.
