Stage in the teaching sequence
Mid-point in a lesson
The teacher regularly used a formative assessment technique often referred to as hinge- or hinge-point questions. She would pose a question in the mid-point of a lesson and require that all students respond so that she knew who had and who hadn’t ‘got it.’
The teacher used the following question (taken from a WAMSE past test paper). The students moved to pre-allocated corners of the classroom to show if they had selected A, B, C or D. This allowed the teacher to very quickly ascertain the number of students who understood the concept.
Using the information
The teacher used the activity as teaching opportunity and had students explain to each other why B was the correct answer. She also noted the need to revisit the concept in the next part of the lesson.
