Using a concept map knowledge management system to enhance the learning of biology


OutlinesMotivationObjectivesMethodologyExperimentsConclusionsComments


Motivation The lack of information about how students categorize, reorganize, and link their perceived concepts, would result in teachers not understanding the learning of students with different cultures and backgrounds.


Objectives

• The CMKMS can promote teaching activities step-by-step and improve effective student learning.


Methodology

Methodology


Experiments – Statistics method(1) ANOVA(2) Tukey’s HSD Test(3) McNemar test


Experiments


Experiments – ANOVA

F ＝ (SSB/degree) ／ (SSW/degree)

＝ 366.45/29.95 ＝ 12.24

Conclusions– The CMKMS made a positive contribution to the

teaching of biology and learning strategy for students.

– This research offers a platform on which group brainstorming sessions can be structured, knowledge and values can be integrated, and a shared conceptual framework.


Comments• Advantages

– The CMKMS enabled students to intuitively construct and organize their tacit knowledge.

• Applications– Concept Map, Learning biology
