Hi there,
Evaluation in ESL/EFL classes is a basic part of teaching/learning process. It is very essential to provide us with more details about your target group ( sts), their ages, the courses they take, potential evaluation tools followed at your school, etc.
However, students are generally evaluated in terms of their acheivement, class work,quizzes, presentations, and attendance.
As a university lecturer, I follow a grading scale to evaluate my sts for a semester. The scale allocates 20% marks for the first hour exam, 20% marks for the 2nd hr exam, 10% marks for class work ( assignments and participation), 10% marks for quizzes (at least 2), 5% marks for presentations, 5% marks for attendance, and 30% marks for the final exam. The total is 100%. Then, the sts � marks are given values in letters i.e. A is 95% and above A- is 90-94, etc.
Hope this will help.
