We all know that collective efficacy is the new number one influence on students’ learning. And there is good reason for that. In part, efficacious teachers ensure that their students are assessment-capable, which means that students understand their current level of performance and compare that with the desired level of learning. Assessment-capable learners and their teachers select direct, dialogic, and independent learning approaches they know will help attain their shared learning goals. They also seek feedback from others, provide others with feedback, and monitor their learning from acquisition through consolidation to mastery.
