. After going through the processes of building, enhancing,and maintaining in 3PD instructional design model, the coreof this research, which is to analyze students‟ cognitive engagement will be carried out.
Students‟ discussion scriptswill be analyzed according to Van der Meijden‟s analytical framework [12]. His coding scheme has been repeatedlytested in his previous researches (see Kleine Staarman [13]).Finally, the efficiency of the developed system will be evaluated with respect to students‟ level of cognitive engagement (can it excites the level of cognitive engagement to the higher degree), students‟ pattern of interactions and its‟ relationship with level of cognitiveengagement, and students‟ academic performances. The following sub-topics will provide greater insight oneach elements of the proposed theoretical framework. A. Cognitive Engagement in Online Learning
The definition of cognitive engagement is adapted from
Zhu‟s
[2] previous work. His definition of cognitive engagement is the students‟ attention to discussion messages, which can be observed from several postingsbehaviour [2]. According to Zhu [2], students‟ mental effort can be translated in activities such as seeking, interpreting,analyzing and summarizing information, critiquing andreasoning through various opinions and arguments, andmaking decisions. Respectively, the related activities are thecharacteristics of collaborative co-construction of knowledge [12]. Hence, cognitive engagement with thisrespect can also be understood as students‟ sustained mentaleffort for co-construction of knowledge while solving thegiven task.
