Research Design
Participants
Eighty Grade 5 grade students (n = 80, mean age ± SD = 11.20 ± 0.40 years) and a science teacher (female,
age = 37 years old, teaching science of elementary school for five years) were recruited in this study. The
controlled group involved 40 students (n = 40, mean age ± SD = 11.25 ± 0.44 years) who need to learn the
dissolve concept on the Web pages and complete the homework which was assigned by the Web pages by
themselves. The experimental group involved the other 40 students (n = 40, mean age ± SD = 11.15 ± 0.4436
years), and every four students were grouped in a team. The experimental group students need to learn the
dissolve concept on Web pages as same as the controlled group, and also need to complete the homework
which was assigned by the Web pages with team members. Furthermore, the experimental group students need
to present their homework to other teams and provide feedbacks and suggestions to other teams.
The science teacher was responsible for choosing the science Web pages about dissolve concept and
answer students’ questions after they learned the concepts from Web pages by themselves completely.
Although the science teacher had taught science in elementary school for five years, she did not teach the
students in this study before
