In addition, it was found that the Type I scores of students in the experimental group did not have significant different in comparison with those of the students in the control group, implying that the innovative approach was more effective in improving the students’ classification knowledge (Type II) than improving their basic knowledge (Type I) of plants. This finding was expectable since Type II test was more relevant to the functionality of the MKC, which guided the students to observe and classify plants in the school campus.
