22  Information technology (IT) has brought educator more opportunity to fulfill instructional goals.  Previous research proved IT is beneficial to learning environment. Ex. Hwang and Kuo(2011) proposed a web-based learning approach embedded information- summarizing strategy to improve the web-based problem solving abilities of primary students. Introduction (1/2)

3  However, without any scaffold, students could get lose on the Web.  To address the issue, a collaborative web-quest learning approach is proposed in the study.  web-quest learning tasks  Jigsaw II

4 Did the students who learned with the Jigsaw II-based web-quest approach have better learning achievements than those who learned with traditional web-quest approach or other collaborative web-quest approaches?

 There are one hundred and thirty-four participants, who were divided into three groups.  Forty-three students in Control group, conduct web-quest with individual learning  Fifty-five students in experimental group one, conduct web-quest with Jigsaw II approach.  And Thirty-sixth students in experimental group two, conduct web-quest with learning together approach. 5

8  The comparison was made among three treatment groups, whose pretest and posttest score were analyzed with the analysis of covariance (ANCOVA) methods.  The homogeneity of pretest score of three groups was tested first and the result showed no significant difference (F=2.68, p >.05), indicating that three group students have same prior knowledge of computer network and information society.  Afterward, ANCOVA was used to analyze the data with pre-test scores as covariates in order to adjust for the initial differences in the sample.

9 Table 1 ANCOVA results and descriptive statistics for students ’ achievement of three different strategies The result, shown in Table 1, reveals that there is significant difference among three treatment groups (F=24.42, p <.001). The experimental group one significantly outperformed the experimental group two and the control group.

10  Previous studies showed that learning activity embedded with web-quest model would improve students’ achievement and attitudes. However, few of them investigated the effect of integration of web-quest model with other learning strategies on students’ learning outcomes.  Accordingly, the study attempts to investigate the effect among web-quest model embedded in different learning strategies.

11  The integration of web-quest mode with Jigsaw II collaborative learning could produce effectiveness as follows:  Students’ learning achievement.  Understanding computer network and information society course in-depth.
