The college students who have relatively weak academic background feel more difficult in learning programming language grammars and programming skills in introductory course. At the end of semester, most of students had the negative attitude to programming and only a few students could write the programs for the given problems because they spent most of time to learn grammars instead of learning problem solving skills and logics. In this study, we propose to use Scratch in introductory programming course to help students to understand grammars and problem solving skills. It's necessary to educate first-time programmers how to solve the problems before they learn grammars of the programming language in their first programming language course. This paper shows that Scratch allows students not only to learn problem solving skills in programming but also to motivate students themselves in the class.

This study touched on the effect of the different electronic course designs on the programming skills of university students. The researcher used the experimental research design of a quasi-experimental of two experimental groups to achieve the objectives of the study. The first group underwent an electronic course designed in the holistic pattern, and the second group was taught a course in a sequential pattern. This experimental design was intended to measure the impact of these two learning modes on the learners' cognitive and performance achievement of programming skills. An achievement test and observational form were the data collection tools. Data were analyzed statistically using Pearson correlation, Mann Whitney Test, and Alpha Cronbach. The findings revealed statistically- significant differences between the mean scores of the students of the first and second experimental groups in favor of the former concerning the observational form and the latter in the cognitive test. Based on the findings, some recommendations are suggested. Due to their effectiveness in the educational process, expanding using the e-courses at universities is vital. The university teachers are highly recommended to design e-courses and provide technical and material support to the e-courses user to fulfill their design purpose.

It is reported that programming education contributes to improving problem solving skills by developing higher thinking skills. As many researches mention the need of programming education, they point to the fundamental difference by gender. This study aims to find out the cause of low interest and achievement levels in programming education in female students. To achieve our goals, we chose 133 specialized high school students in which programming class is being carried out as subjects of our study. The results of this study showed that female students had the tendency to prefer individual projects to a more systematic method of problem solving. Moreover, according to correlation analysis, higher programming skills in female students showed various problem solving processes. This study shows significance in proposing different study methods according to gender to obtain effective programming study.

Recently, Information Communication Technology(ICT) is one of the most important technology that supports the modern society. As the ICT rises, the needs of the nurturing talents, who can develop a service or hardware on the basis of the humanities increases. As a result, teaching programming skills to students studying humanities and social science are essential. Also, it is important to train students studying science and engineering to write their thoughts logically. In order to serve these students, we introduce a pedagogy for computer programming using programming essay. Since a program is a sequence of the operations based on the programmer's logical thinking, programming can be considered as describing programmer's logic in the proper order using programming syntax. In this research, we train students to describe their logic using natural language. Students write down their essays for a given programming problems. Also, we introduce a pedagogy guideline using programming essay.

In a rapidly changing society with the Fourth Industrial Revolution, future students should have the skills to utilize and organize high-quality knowledge, not the amount of knowledge. With the launch of the revised curriculum in 2015, the curriculum has been reorganized based on competency and the software education has been seeking capabilities such as 'Cultural computing knowledge', 'Computational thinking', and 'Collaborative problem solving skills'. Therefore, practical collaboration tools and education programs that can be used in the field of education are developed based on Pair Programming, which is a specific collaborative learning strategy to develop cooperative problem solving skill. The educational program using this collaboration tool was developed with a focus on developing computational thinking and collaborative problem solving skills through Pair Programming rather than focusing on learning grammar of programming language and programming techniques. In a educational program, students will be able to use collaborative tools for pair programming and foster collaborative problem-solving skills.

In this research, we applied the problem-based learning (PBL) on a college computer system programming course and analyzed how it affected students' academic achievement and job essential skills. After course contents analysis, we divided the course into three subsections and provided three problems for each subsection. For measuring the effect on academic achievement, we compared with scores of the previous year's students. For job essential skills, we used Korea collegiate essential skills assessment (K-CESA) operated by Korea Research Institute for Vocational Education & Training. Students took the test twice before and after the course. Results showed that PBL has positive effects on both academic achievement and job essential skills.

The programming language is a core education area of software that is becoming increasingly important in the age of the fourth industrial revolution, but it requires mathematical knowledge and logical thinking skills, so that many local private university and college students with low basic skills are having difficulties learning it. This problem occasionally causes SW-major students to lose interest and confidence in their majors during the introductory course of programming languages; making them change their majors, or give up their studies. In this study, we designed an instructional model using Scratch for educating C-language which is a typical programming introductory language. To do this, we analyzed the concepts that can be trained by Scratch among the programming concepts supported by C-language, and developed the examples of Scratch for exercising the concepts. In addition, we designed an instructional model, by which the programming concepts are first learned through Scratch and then C-language is taught, and conducted an experiment on the SW-major freshman students of a local private university to verify the effectiveness of the model. In the situation where SW education is becoming common, we expect that this study will help programming language education of security IT students.

MIT App Inventor 2, much like the other block-based programming languages such as Scratch and Alice, is a useful tool that can be utilized to improve the computational thinking skills for students. The coding and the execution of program are done mainly on the computer in Scratch programming, but in App Inventor 2 programming, the students can execute the program and get immediate feedback on the smart-phone in the middle of the programming. Therefore, we can expect better enhanced learning effect. In this study, it has been claimed that the learning of App Inventor2 can strengthen the computational thinking skills of our students by extracting four core concepts of the computational thinking and then showing how these concepts are applied through the learning of App Inventor 2.

A programming language is very important subject in computer science. But it is difficult for many students to learn programming language. New pedagogical methods and techniques to help students to learn programming are needed. In this paper, we investigated the effects of Pair Programming, and we proposed a Pair programming strategy to improve programming skills. This paper examined the proposed Pair programming strategy. A empirical study showed the proposed teaching and learning strategy has positive effects on achievement and motivated strategies in programming course. Four factors - critical thinking, metacognitive reflection, effort regulation, and peer learning - have positive effects in learning strategies. The proposed Pair Programming strategy improves programming learning and motivated strategies.
