The Teacher Work Sample (TWS) employs almost the same processes that teachers follow in lesson planning and classroom instruction except that TWS is more than mere planning and performance. It also includes developing a Contextual description of the class and as its final step, a Reflection and Self-Evaluation of the instruction. The TWS is, therefore, a blueprint of a complete and ideal teaching performance.
The process involved in creating a TWS can help me better my instruction in the classroom because it is a means by which the would-be teacher becomes familiarized with the real world of the teaching profession, what to expect and how to go about with the rigors of classroom teaching. For instance, the first step in TWS, knowing the characteristics of the learners beforehand, could prevent those awkward moments when the teacher, armed with only a lesson plan, is thrust into a group of students who might not be ready for the planned instruction.
Also, the thorough attention to the details of teaching that creating a TWS demands is an exercise in efficiency that the teacher could bring into his classroom performance. The TWS benefits the teacher in many ways. It develops self-awareness and provides a point of self-reflection to the teacher as a part of the TWS is for the teacher to analyze student performance and determine which parts could be changed or improved.
It enables the teacher to analyze his strengths and weaknesses based on the assessment results. It makes him conscious of the manner in which he designs lessons, and in how to transfer knowledge and assess students correctly. The TWS also gives the teacher a better understanding of his students and their weaknesses and points by which he could focus future instruction. It helps the teacher, therefore, to make better decisions for future instruction.
