A major strength of the design was the ease in navigation that showed the overall usability of the interface design as good navigation allowed the freedom to explore the instruction.The interface design was well organized and easy to read and follow. The module and the screen content were easy to read because of the many visual aids. All of the Mathematics teachers during the evaluation phase revealed that the design communicated clearly to the participant, the learning objectives of Module Two, what they were expected to learn in Module Two. This meant that there were strengths in the design and the presentation of the content. The many learning activities that reinforced content was the strength of the design that showcased in the reinforcement of learning through the varied learning activities. All the Mathematics teachers felt confident answering questions in the assessment and relevant postings for discussion, preferred the method of feedback again here the strength of the design was displayed in reinforcing learning. All of the Mathematics teachers also appreciated the module dates being shown in the design and were motivated to complete the Module while finding it enjoyable and interesting with meaningful content making the whole learning experience and overall strength
