according to the characteristics of the model, SAM is an iterative model, with multiple cycles. From the flexibility of operation, SAM mode has errors or fails to meet expectations later, so it can directly return to the design stage of the previous step to re-iterate the test. From the perspective of complexity, SAM model has only three stages and eight steps, which is light and concise.
in the requirement confirmation stage, SAM emphasizes "doing" and "doing well" for development goals, and pays more attention to solving practical problems. In the confirmation of requirements, SAM adopts the form of cognitive initiation meeting. The cognitive initiation team includes not only performance controllers, content experts (internal experts), budget controllers, project managers and sample designers, but also managers, target students and students who have recently participated in training. When designing the course structure and content, all possible disputes are solved face to face on the spot, which makes efficient use of time and meets the needs of all aspects. In the way of confirmation, SAM uses sample drawing technology and team development at this stage. The demand investigation includes requirements, objectives, sketches and development plans, which are jointly developed by technical experts, students and managers. Team development technology makes the risk of curriculum development lower, the process simpler and the result more effective.
in the course development stage, SAM technology is the ultimate iterative process in the design and development process, and its essence focuses on agility, iteration, efficiency and simplicity. In terms of design and development, SAM's idea is "subtraction", which reduces the number of working procedures as much as possible and directly solves practical work problems.
in the evaluation stage, from the evaluation process, SAM iterated and repeatedly evaluated from the beginning, from loose and general to the first structuring of standard design, and constantly revised the course results, which reduced the evaluation work when the results were delivered. Judging from the evaluation content, the focus of SAM's achievement evaluation is not the integrity of content elements or interaction details, but more concerned with the effectiveness of challenges and activities. In terms of development time, SAM can quickly adapt to the needs of market changes in just one or two weeks. In terms of learning experience, SAM's agile iterative curriculum development technology pays more attention to learners' learning experience, and from the beginning, it is devoted to how to integrate real scenes into curriculum design, so as to make the curriculum closer to actual work and help learners improve their work more effectively. SAM can fully improve the quality of the course by using decomposition technology, crowdfunding wisdom through multiple iterations of different roles, and extracting precipitated experience through cross-iteration.
