Table 1 Assessment standard for pair-level concept maps
From: An integrated approach for knowledge extraction and analysis in collaborative knowledge construction
Dimension | Indicator | Code | Description |
|---|---|---|---|
Structure | Number of layers | NoL | The number of layers in each concept map |
Number of nodes | NoN | The number of nodes in each concept map | |
Number of connections | NoC | The number of connections in each concept map | |
Distributions of nodes | DIS | The score of distribution was measured as the quantity of ideas divided by the number of layers (DIS = NoN / NoL). A higher score of DIS indicated a larger number of nodes distributed for each hierarchy | |
Idea | Overall quality of ideas | QoI | The weighted sum of the number of nodes at each level (QoI = level 1 * 1 + level 2 * 1.5 + level 3 * 2 + level 4 * 2.5 + …). A higher score of QoI indicated a higher quality of a concept map |
|  | Average depth of ideas | DoI | DoI was measured as the overall quality of ideas divided by the number of nodes (DoI = QoI/NoN). A higher score of DoI indicated a deeper idea elaboration on average |
Connection | Overall quality of connections | QoC | The weighted sum of the number of connections for each type (QoC = a * 1 + b * 2) a: There is no relation between two nodes; b: There is an interpretable relation between two nodes |
|  | Average depth of connections | DoC | DoC was measured as the Overall quality of connections divided by the number of connections (DoC = QoC/NoC) |
