3. Samples and sampling method : Experimental group The experimental group has 40 F.1 students ( a class of mixed ability ) from a local secondary school. At the beginning of the research period, the whole class has to take a pre-test in which some grammar knowledge is tested. Then, the class is introduced with the Web-based Language Learning Program – ‘Online English Grammar’ so as to help them to familiarize with the system. When all the students are sure how to operate the system, they have to learn the grammar taught by the program during the English lessons. After one month, the students have to take a pro-test in which the grammar knowledge will be tested. Control group The control group has 40 F.1 students ( another class of mixed ability ) from the same school. They all took the pre-test which is identical to that for the experimental group. During the research period ( one month ), the teacher will teach the class with the same content taught by the ‘Online English Grammar’. After one month, the class will sit for the same post-test as that for the experimental group. How will the data be collected and analyzed ? The students’ progress will be studied by comparing the Pre- and Post-test results of both groups and analyzed by the significance t-test respectively.
