In this experiment, teacher pre-taped the lectures and put the taped lectures on the course website for students to watch before class. For in class activity, lab packages, including hands-on experimental software tool and worksheets, were created and used for students to practice with. Therefore, not only a more learner-centered environment was created, but the essence of “learning by doing” was also implemented. The experiment was conducted at a rural high school for three weeks. One hundred fifty-six first-year high school students in four classes participated in this study. Two of the classes were designated as the control group and the other two classes as the experimental group. The post-experiment achievement test was given to both experimental and the control groups after three weeks of learning. The ANCOVA results indicate that the two groups of students had a similar learning achievement. However, the questionnaire reveals that students exhibit more positive attitude toward this new learning approach. The research findings offer teachers reasons and directions for changing their teaching method. Practical suggestions for implementing this new approach in high school to other higher-level computer science topics are also offered.
