This study aimed to design a web-based learning model to enhance pre-service teachers’ competencies in the Interconnection of Multiple Levels of Representation (IMLR). The model contains multimodal representations with assignments and probing questions; it creates social engagement through online discussion forums and online assessment as feedback on learning performance. The validity of the model was evaluated by expert judgment, while the feasibilty of the model was explored through a limited test with students using the quasi-experimental method. The results showed that the implementation of a web-based model increased the pre-service teachers’ abilities in IMLR on each subtopic of chemical equilibrium in aqueous solution. The pre-service students also showed good abilities to resolve problems with interconnection patterns that progressed from macroscopic to submicroscopic and symbolic, rather than starting from submicroscopic and moving to symbolic and macroscopic. It can be concluded that the web-based learning model enhanced the pre-service teachers’ understanding of the submicroscopic level, changing existing problem-solving ability patterns from macroscopic–symbolic into six interconnection patterns, and improving student learning patterns. |
