With the widespread use of mobile internet, cloud computing, big data, and artificial intelligence in the field of education, a new teaching model based on cloud technology has been rapidly developed. This new model follows the curriculum's "construction-implementation-evaluation" process and includes a quaternity intelligent cloud teaching framework consisting of teaching content, teaching tools, teaching management, and teaching evaluation. This framework comprises intelligent cloud teaching materials, cloud-based classes, cloud-based big data management, and an intelligent monitoring system for teaching quality. The data and services of these four modules can be mutually invoked and supported. Intelligent cloud teaching has been studied and implemented in many core courses, such as "Optoelectric Technology," "Applied Optics," "Physical Optics," "Photoelectric Information Comprehensive Experiments," and "Electrodynamics." The implementation of intelligent cloud teaching has shown several advantages. Firstly, it allows students to make full use of fragmented time for autonomous learning, which is particularly beneficial for optoelectronic majors that require knowledge from various fields such as optics, electronics, mechanics, computer science, and materials science. Secondly, it enables teachers to promote formative evaluation and research-oriented teaching reform, and to continuously improve their courses. Thirdly, it facilitates intelligent monitoring of teaching quality, with relevant teaching big data being used to evaluate teaching and learning and support evidence-based teaching research. Lastly, it provides a historical database that can support professional construction and certification, meeting the requirements for output orientation, quality assurance, achievement evaluation, and improvement. In order to further promote the intelligent cloud teaching model, several suggestions have been proposed, including optimizing the construction of evaluation and incentive mechanisms and implementing technologies to improve the intelligent cloud teaching platform.

The photoelectric courses such as photoelectric technology, optical communication, optoelectronics, and photoelectric detection and signal processing, which own the properties of specialty, integrity and practicability, are usually difficult to grasp well only by classroom teaching. To help undergraduates to understand the photoelectric courses’ knowledge and improve their problem solving ability, developing the project-based integrated design experiments is an effective method to inspire the students’ interest and improve their innovative practical ability.

Firstly, the main properties of photoelectric courses’ integrated design are analyzed, and the basic principles of selecting the proper topics to design some training projects are summarized. A well designed project should be comprehensive, feasible and cost effective, and the project can be separated into several parts with gradually increasing difficulty, which is good for implementing it step by step and inspiring the students’ potentials. Secondly, some teaching research and practice of integrated design experiments are implemented based on the photoelectric technology course offered in our university, and four integrated design projects are introduced, which are measuring the rotating speed, direction and stop position of a rotating wheel, designing a laser reconnaissance warning and jamming system, making an analog and digital communication system by utilizing a white light LED and making a photoelectric detection system for blood oxygen saturation. The experimental arrangement and implementing experience are also provided and investigated. Thirdly, some crucial problems discovered in our teaching practice, such as optimizing the design contents and demands of project, helping students’ to overcome various difficulties, making teachers become experienced, and evaluating the project design results efficiently and accurately, are also analyzed and discussed to improve and perfect the quality of integrated design experiments. In conclusion, the photoelectric integrated design experiments have been introduced to help undergraduates to master the theoretical knowledge and train their problem solving ability, and our teaching practice experiences have been summarized and provided based on the photoelectric technology course, which can be spread to other photoelectric courses.

This article analyzes the features of fostering optoelectronic students’ innovative practical ability based on the knowledge structure of optoelectronic disciplines, which not only reveals the common law of cultivating students' innovative practical ability, but also considers the characteristics of the major: (1) The basic theory is difficult, and the close combination of science and technology is obvious; (2)With the integration of optics, mechanics, electronics and computer, the system technology is comprehensive; (3) It has both leading-edge theory and practical applications, so the benefit of cultivating optoelectronic students is high ; (4) The equipment is precise and the practice is costly. Considering the concept and structural characteristics of innovative and practical ability, and adhering to the idea of running practice through the whole process, we put forward the construction of three-dimensional innovation and practice platform which consists of “Synthetically Teaching Laboratory + Innovation Practice Base + Scientific Research Laboratory + Major Practice Base + Joint Teaching and Training Base”, and meanwhile build a whole-process progressive training mode to foster optoelectronic students’ innovative practical ability, following the process of “basic experimental skills training - professional experimental skills training - system design - innovative practice - scientific research project training - expanded training - graduation project”: (1) To create an in - class practical ability cultivation environment that has distinctive characteristics of the major, with the teaching laboratory as the basic platform; (2) To create an extra-curricular innovation practice activities cultivation environment that is closely linked to the practical application, with the innovation practice base as a platform for improvement; (3) To create an innovation practice training cultivation environment that leads the development of cutting-edge, with the scientific research laboratory as a platform to explore; (4) To create an out-campus expanded training environment of optoelectronic major practice and optoelectronic system teaching and training, with the major practice base as an expansion of the platform; (5) To break students’ “pre-job training barriers” between school and work, with graduation design as the comprehensive training and testing link.
