Student-centered case-based teaching and online–offline case discussion in postgraduate courses of computer science

This study explores a student-centered teaching method in postgraduate courses. Teacher-centered classroom teaching cannot fully stimulate learning initiative and enthusiasm of students. Student-centered means that students actively learn and construct knowledge by participating in teaching activities. This study presents a student-centered online–offline hybrid teaching method, which adopts student-centered case-based teaching and online–offline case discussion in the postgraduate courses of computer science. The latest engineering cases are integrated into teaching and a case library is constructed. Taking the digital image processing course as an example, student-centered teaching allows students to choose what to learn and how to learn. Case-based teaching makes students better understand the application of theory of knowledge. It can introduce multiple perspectives, promote understanding and reflection on problems, and help students develop higher-level thinking, analysis, and synthesis skills. This study explores online–offline case discussion method in the student-centered teaching and proposes the principles of case design of postgraduate courses. Revised Bloom’s taxonomy is used for teaching assessment. The actual teaching effect shows that student-centered case-based teaching and online–offline case discussion have achieved better teaching effect.

Discussion on Curriculum Reform of Digital Image Processing under the Certification of Engineering Education

At present, engineering education professional certification is being recognized by more and more colleges and universities. Engineering education professional certification is oriented by ability training, and puts forward specific reform requirements for all aspects of the talent training system. This paper takes the digital image processing course as an example and discusses the teaching reform under the talent training system of engineering education professional certification talents. In this paper, from the formulation of digital image processing curriculum objectives, the setting of teaching content, procedural assessment method, the design of online hybrid teaching mode, etc., and the three core concepts of engineering education professional certification to the application of the digital image processing teaching reform, practice has proved that after a series of teaching reform, the teaching effect has been greatly improved.

An Effective Practice Method of Visual Case Teaching

According to the needs of computer professional training, in the teaching of image processing course, the traditional teaching methods can not adapt to the pace of the current teaching reform. In the research, combined with the characteristics of digital image processing course, this paper explores a new idea of how to integrate the vision, thinking and teaching knowledge of the educated, which is in line with the law of human understanding and expression of knowledge. This paper also discusses the methods, strategies and mechanisms of case teaching construction, unifies the integration goal of visual teaching and learning with the construction of teaching materials, case construction and visual teaching process, integrates the ideas and concepts of modern teaching into the visual teaching of image processing, and explores new means of personnel training, specifically, the paper studies the visual teaching method of digital image processing course, and puts forward the development strategy of software engineering for the construction of visual teaching. Firstly, it is necessary to analyze the requirements of the construction of the visual teaching for digital image processing course. Then, after the content of the visual teaching construction is determined, the content construction of the teaching is carried further, including the construction of visual teaching material library, etc. Finally, the test of the construction results of visual case teaching is carried out. Overall, a feasible strategy is proposed for visual teaching, which provides an effective way for training new talents.

A Low Risk Hybrid Teaching Methodology for Improving the Motivation Levels of Students: A Casestudy on Digital Image Processing Course

The motivation levels of the contemporary engineering students to sit and learn in a traditional classroom is relatively low, due to the exposure of new technologies since their childhood. They don't believe in totally classroom study and have little patience to sit long hours in the classroom, as they see alternative ways of learning outside the classroom. Hence, there is need for devising new pedagogy techniques which can motivate them to attend the class, and at the same time, to study outside the classroom and out of institution hours. However, the age-old pedagogy method of deductive learning and class room teaching can't be thrown away all of a sudden. So a low risk method of teaching is required for the universal acceptance by the students and by the authorities. In this paper, a hybrid low risk teaching methodology is considered for the undergraduate course of Digital Image Processing for the students of Electronics and Communications Engineering (ECE) specialization. Three topic wise active learning activities: quiz, group discussion and simulations were devised and implemented along with the traditional classroom teaching. A course end survey was conducted at the end of the course. The responses to the survey clearly showed that the motivation level of the students significantly increased after the implementation of active level methodologies. The significant increase in the marks obtained in the II internal examination also confirm the effectiveness of the hybrid technique used. The results are very much encouraging to the teacher, to implement the proposed technique in the next semester also as indicated by the students.

Project-Based Learning in Digital Image Processing Course

The current paper presents project/problem-based learning (PBL), equipped with contemporary technologies as a strategy to revolutionize traditional teacher-centric classrooms to student centric systematic and innovative learning. Understanding the core concepts of image processing techniques and identifying its applicability in real-time scenarios requires in-depth visualization. Classroom lecturing is trivial for students to appreciate the significance of image processing systems. On learning through real-world projects, nearly every aspect of students' experience change. Learners pursue the subject knowledge on their own with their own meaning, under the guidance of an instructor. Instructors design the project as a framework for learning, subsequently students wind up using technology to access and analyze information in all dimensions possible. The article presented comprehends important aspects of PBL and illustrates the digital image processing sessions carried out using the proposed approach.

INTRODUCING ALGORITHM DESIGN TECHNIQUES IN UNDERGRADUATE DIGITAL IMAGE PROCESSING COURSES

This paper documents the development and first offering of an undergraduate course in Digital Image Processing at the Rey Juan Carlos University, Madrid (Spain). The paper describes how the appropriate introduction of main Algorithm Design Techniques can successfully assist the students to achieve a comprehensive understanding of image operations and related algorithms. Image processing problems offer a natural way to present real world problems where the students can use their algorithmic knowledge. Furthermore, image processing solutions are needed from a methodological development and require efficient well-designed algorithms. This paper presents an effort in the integration of Algorithm Design Techniques in a Digital Image Processing course with a very practical scope.
