In 1984, Novak and Gowin presented two constructivist techniques for learning: concept maps and the Knowledge Vee diagram. Gowin’s Knowledge Vee diagram facilitates students’ use of their metacognitive processes to newly acquired information in order to make meaningful connections. Graphic organizers are knowledge visualization tools that support meaningful learning. Digital knowledge mapping offers the potential to link knowledge of complex theories and concepts to text, images, websites, virtual learning environments, and audio and video resources. Knowledge mapping as an instructional strategy promotes meaningful learning. Students utilizing visual thinking strategies to interpret and produce visuals will help foster a higher level of learning. The challenge for teachers is to select instructional strategies that integrate visual literacy into the curriculum. This case study discusses the effectiveness of concept mapping and graphic organizers as an instructional strategy to promote visual literacy in an online graduate-level course. Overall, the findings demonstrate the benefits of integrating concept mapping with social networking for student learning outcomes. The results of study III indicate that groups with two to seven members perform better than larger groups. Study III considers each participant’s contributions to identify an optimal group number. The findings of studies I and II are consistent, demonstrating that the students constructed more comprehensive concept maps and had a higher modification period and frequency with SCM than with ICM, which indicates that in a social network learning environment, SCM is favorable to ICM. On the basis of study I, study II extends the controlled environment within an open social networking environment with a total of 1106 SCM maps and 569 ICM maps to produce an improved overview of concept mapping. A platform named ( ) is utilized to examine the SCM and ICM activities under three studies, which drove the following research questions: (1) Do map structure (i.e., propositions, hierarchies, examples, cross-links, and scores) and mapping activity (i.e., map modification period and frequency) differ between ICM and SCM in students on specialized courses? (2) Do map structure and mapping activity differ between ICM and SCM in students on general education courses? (3) What are the effects of group size on SCM? In study I, four classes are selected to ensure a strong social network learning environment control. This paper explores the effects of social network–supported group concept mapping (SCM) activity and compares them with the effects of individual concept mapping (ICM) activity. However, little effort has been made to explore the effects of social network–supported concept mapping compared with traditional individual concept construction. Social networks provide traditional concept mapping of new opportunities for concept construction with grouping, social interaction, and collaborative functions. The present investigation discusses the concept, the features and theoretical underpinnings of CmapTools, as well as reports on the research regarding its educational value and use in different educational contexts, including ESP studies at the university. To this end, 23 selected publications have been analysed. The relevant literature used for this investigation was identified by searching several multidisciplinary and subject-related online databases. The aim of this investigation is to report on the results of the analysis of the use of CmapTools as a potential pedagogical approach for teaching and learning in different educational contexts, including the studies of English for Specific Purposes (ESP) at the university. IHMC CmapTools is a software tool that empowers users to build their knowledge using concept maps, to share and to publish them. Research to date acknowledges the efficiency of concept maps as a pedagogy to facilitate meaningful learning, yet in this digital era, there has been a growing interest in computer-supported concept map building and its educational benefits.
