When I was completing my Bachelor of Education I was lucky enough to be able to attend a guest lecture given by Richarch Zerbe entitled
assessment For Learning. In his lecture, he addressed three primary types or uses of
assessment that changed the way I thought about evaluation. The three types he identified are:
assessment of learning,
assessment for learning and
assessment as learning. While he was speaking specifically about assessing primary and secondary school
children, his lecture is directly applicable to teaching
english as a foreign language at any level or class.
assessment of learning includes evaluation techniques such as summative
assessments or final tests and report cards. This type of
assessment provides evidence of achievement and progress. Final tests and official
assessment of assignments or presentations are what my mind used to immediately jump to when I thought of ‘evaluation' and ‘testing', but Zerbe placed little value of this type on this type of
assessment, instead referring to it as merely a way to check to see if students have met their intended curriculum goals. He did, however, accept it as a necessary part of evaluation and stated that in order to be useful for the student, it is important to use descriptions of what they did well and what they need to improve on instead of letter grades or scores. Even though most academic institutes will insist on quantitative scores for record-keeping, qualitative
assessments are more useful for students understanding how they did than simply getting a B stamped on the top of their work. Further, in order to be a fair
assessment of a student's knowledge and understanding, it is imperative that they know what is expected of them if they want to achieve an A (or level 4, or 90%, etc). They need to be shown examples and the rubrics or guidelines by which the
teacher is going to evaluate them.
The second method of
assessment Zerbe identified is
assessment for learning. This type of
assessment includes formative and diagnostic testing as a way to inform
teachers where students are and where they need support. Zerbe recommends using formative tests as a continuous investigative tool to take constant readings about students' progress and positions. Instead of being used to officially evaluate students,
teachers can use these tests or
assessments to get an idea of how well students have grasped recent material and how ready they are to move on. There is little point rushing ahead if students have not understood or cannot
apply what they were previously taught, especially if the concepts build on each other.
Zerbe names the third type of
assessment ‘
assessment as learning'. This type of
assessment is an active process where students personally monitor their own learning. The process of self-evaluation helps students understand the material and also understand themselves as learners better than always being told their mistakes and how to fix them. Zerbe recommends that we teach students how to give feedback and correct their own mistakes. Having to edit and correct their own mistakes (and those of others), albeit with guidance from the
teacher, is much more effective than always relying on the
teacher for answers. There are several ways this can be achieved; starting with the idea that
assessment should be done with students as opposed to to students. A few examples of this are giving direct feedback by holding (even brief) conferences with students where you discuss their work, having students complete checklists to see if they have included the necessary criteria and working in teams where students learn from each other. This type of
assessment is often underappreciated, but always invaluable as it develops meta-cognition, critical thinking skills, communication and interpersonal skills.
All three types of
assessment are useful in isolation, but when used in conjunction with each other, they are very effective teaching tools.
