In the first phase of the two-stage work process, we evaluated the learning system and interface research of Pinnacle, first proposed optimization suggestions based on our initial experience of using the learning system, added individualized or group reading project contents, and used differentiated teaching to assist students; at the same time, we conducted a literature review to evaluate the relationship between the system and reading comprehension, interpreted students' reading thinking process, and proposed strategies to solve students' reading difficulties. In order to analyze the user-friendliness of the system and explore related research on e-learning systems in the field, we further summarized the usability evaluation methods of the system, summarized the reading behaviors to enhance users' willingness to continue using the system and to facilitate e-learning; summarized the main/sub-items of the system evaluation (navigation interface, visual satisfaction, and system feedback) to assist the reference of the test, while the user-friendliness of the interface operation was based on our own experience and user feedback. The test suggested that the effectiveness of the navigation interface and the visual distinction between clear guidelines and prompts in the system feedback could reduce the cognitive load of users.

In the second stage, we designed the one-page website structure of the learning system of PILT, and integrated the pain points of reading literacy based on the content of the first stage, including four pain points: lack of basic literacy skills, change of literacy-oriented test questions, blurred concept of teacher literacy, and too much time taken up by the Internet; next, we recorded the competitive analysis of the learning system and summarized the six structures of how to promote the value positioning of the product from the learning website, and linked them with the concept of PILT one-page website. The concept of one-page website was constructed from the above information, and the website structure was designed with Adobe XD.
