Keeping records of observations improves reliability and can be used to enhance understanding of one student, a group, or the whole class' interactions. Sometimes this requires help from other teachers. For example, Alexis, a beginning science teacher is aware of the research documenting that longer wait time enhances students' learning (e.g. Rowe, 2003) but is unsure of her behaviors so she asks a colleague to observe and record her wait times during one class period. Alexis learns her wait times are very short for all students so she starts practicing silently counting to five whenever she asks students a question.
Teachers can keep anecdotal records about students without help from peers. These records contain descriptions of incidents of a student's behavior, the time and place the incident takes place, and a tentative interpretation of the incident. For example, the description of the incident might involve Joseph, a second grade student, who fell asleep during the mathematics class on a Monday morning. A tentative interpretation could be the student did not get enough sleep over the weekend, but alternative explanations could be the student is sick or is on medications that make him drowsy. Obviously additional information is needed and the teacher could ask Joseph why he is so sleepy and also observe him to see if he looks tired and sleepy over the next couple of weeks.
Anecdotal records often provide important information and are better than relying on one's memory but they take time to maintain and it is difficult for teachers to be objective. For example, after seeing Joseph fall asleep the teacher may now look for any signs of Joseph's sleepiness ignoring the days he is not sleepy. Also, it is hard for teachers to sample a wide enough range of data for their observations to be highly reliable.
Teachers also conduct more formal observations especially for students with special needs who have IEP's. An example of the importance of informal and formal observations in a preschool follows:
The class of preschoolers in a suburban neighborhood of a large city has eight special needs students and four students the peer models who have been selected because of their well developed language and social skills. Some of the special needs students have been diagnosed with delayed language, some with behavior disorders, and several with autism. The students are sitting on the mat with the teacher who has a box with sets of three “cool” things of varying size (e.g. toy pandas) and the students are asked to put the things in order by size, big, medium and small. Students who are able are also requested to point to each item in turn and say this is the big one”, this is the medium one” and this is the little one”. For some students, only two choices (big and little) are offered because that is appropriate for their developmental level. The teacher informally observes that one of the boys is having trouble keeping his legs still so she quietly asks the aid for a weighted pad that she places on the boy's legs to help him keep them still. The activity continues and the aide carefully observes students behaviors and records on IEP progress cards whether a child meets specific objectives such as: “When given two picture or object choices, Mark will point to the appropriate object in 80 per cent of the opportunities._ The teacher and aides keep records of the relevant behavior of the special needs students during the half day they are in preschool. The daily records are summarized weekly. If there are not enough observations that have been recorded for a specific objective, the teacher and aide focus their observations more on that child, and if necessary, try to create specific situations that relate to that objective. At end of each month the teacher calculates whether the special needs children are meeting their IEP objectives.
