Response to the outbreak of COVID-19, classes this semester is mainly replaced by online teaching to ensure continual learning. Teachers are actively exploring effective online teaching methods to provide a good learning experience for students at home. This paper presents an online teaching model based on the idea of Problem-Based Learning (PBL) and take “Data Structure” as an example to discuss the design of the teaching process and problems.

At the beginning of 2020, the outbreak of COVID-19 hit majority of countries and regions on this planet. To curb the spread of the novel coronavirus outbreak, schools and universities in China are required to postpone the start of the spring semester until the epidemic is under control. A record number of children and youth cannot continue their regular study life. Under such situation, Internet and online courses become the best solution. Many schools and universities are now embracing online learning as a substitute of traditional teaching. Courses are conducted online via different platforms, including its internal online classroom system, video conferencing and open online education platforms such as XuetangX, CNMOOC, IMOOC and the China University MOOC which provides a variety of courses available to the public in China. Many professors have been livestreaming their classes, playing recorded course videos and organizing discussions using instant messaging apps such as WeChat, QQ, or conference system online. Online education provides solutions to crisis, but the shift from physical classrooms to online ones has not been without problems. There are some problems in teaching online. Teachers are not able to know if students are slacking or paying attention. Students might not be able to ask questions to gain a better understanding. Students at home need self-disciple when taking online classes, which is difficult for many students who are immersed in games and the internet. They may not know how to control themselves at home when taking online classes. The home environment lacks the learning environment that schools have. So, how to effectively implement online teaching is a topic worth studying. This study presents an effective teaching method for online teaching. The basic idea of this method is Problem-Based Learning (PBL). During online teaching, teachers guide, check and manage student’s study by different kind of problems or questions while students acquire knowledge by answering and solving problems. And the application of PBL teaching method in Data Structure, a professional basic courses of computer science, is discussed.
Since the COVID-19 outbreak, the practice of teachers and students has proved the feasibility of online teaching and has realized “no suspend teaching, no suspend learning”. So far, we have completed teaching the first three chapters. The questionnaire survey shows that students are very welcome to this teaching model and average scores of three unit tests even exceed those of traditional teaching in the past.
The Kavian Scientific Research Association (KSRA) is a non-profit research organization to provide research / educational services in December 2013. The members of the community had formed a virtual group on the Viber social network. The core of the Kavian Scientific Association was formed with these members as founders. These individuals, led by Professor Siavosh Kaviani, decided to launch a scientific / research association with an emphasis on education.
KSRA research association, as a non-profit research firm, is committed to providing research services in the field of knowledge. The main beneficiaries of this association are public or private knowledge-based companies, students, researchers, researchers, professors, universities, and industrial and semi-industrial centers around the world.
Our main services Based on Education for all Spectrum people in the world. We want to make an integration between researches and educations. We believe education is the main right of Human beings. So our services should be concentrated on inclusive education.
The KSRA team partners with local under-served communities around the world to improve the access to and quality of knowledge based on education, amplify and augment learning programs where they exist, and create new opportunities for e-learning where traditional education systems are lacking or non-existent.
