Research on the construction and application of engineering cost teaching platform based on adaptive learning

Abstract

The “T multi-layer architecture” refers to the three-tier application architecture commonly used in web development, which consists of the presentation layer (client), application logic layer (middle tier), and data access layer (server). This architecture extends the traditional client/server model by introducing a dedicated application server layer to handle business logic, thereby separating user interface functions from data processing. The term “T” metaphorically represents the structural division among these layers, enabling modular management and load balancing. The client-server interaction follows a three-tier model: the client layer handles user interface communication, the application server layer processes business logic, and the data layer manages database operations. This separation allows the application server to share processing loads, addressing the overburden issue in traditional C/S architectures. The middle tier acts as a bridge, ensuring seamless data flow between the client and server. The 30% increase in student engagement was measured via dual methods (1) automated tracking of platform interactions (e.g., number of case studies accessed, quiz attempts, and discussion forum contributions): and (2) a 5-point Likert scale survey administered mid-course and at completion. For the 80% understanding improvement, students completed pre-and post-course concept mapping exercises focused on complex cost topics (e.g., bill of quantities valuation), with evaluators blind-coded to assess map complexity and accuracy. On average, students spend approximately 2 hours per week engaging with course content on the ECTP. A survey of students rated the user interface with a high ease-of-use score of 4.5. Furthermore, 70% of students noted significant improvements in their problem-solving abilities after using the platform. Project cost information management involves complex logic and lengthy processes. An efficient cost information system is essential to manage these workflows and standardize business procedures. The adaptive learning-based ECTP was designed with this goal in mind, integrating fragmented cost data for educational purposes.
