“Computer Application in Major Field” is a subject that studies the ways of using applications for the simulation and analysis of scientific and technological calculations in the field of materials engineering and hydrodynamical processes in hydrometallurgy.
In the past, teachers had some problems with stimulating students’ thinking for developing their creativity and raising their program application abilities.
Therefore, Kim Chol Nam, a researcher at the Faculty of Metal Engineering, has introduced problem-based learning (PBL) whereby students could seek discussion points and solutions to them on their own, in order to enhance their application abilities of simulating and analyzing hydrodynamic problems arising in process operations.
First, while he was explaining the principle of the process by using a virtual reality system, he led them to discovering problems and finding solutions from FLUENT library. It was helpful for students to have a full understanding of the hydrodynamic principles of hydrometallurgy.
After they studied the hydrodynamic quantities for turbulent kinetic energy in FLUENT library, he taught them the method of determining the agitation characteristics so that they could have a technical and hydrodynamic notion of hydrometallurgy. In a word, he emphasized that the agitating condition was an important factor in the chemical reactions made in a leacher with air agitation and the quantity was turbulent kinetic energy and that it could be calculated simply in FLUENT. As a result, they became more enthusiastic in their study with confidence that they could solve any hydrodynamic problems by utilizing applications.
Second, he designed his teaching plan in a way that students could be familiar with how to simulate and analyze the process through an understanding of the process, a determination of its factors, an analysis and a determination of reasonable parameters, and raise their application ability, all by introducing PBL.
It is the basic purpose of PBL to raise the ability of application and self-study by making the discovery of questions and solving them a process of inquiry and cooperation.
With a good understanding of the chemical reaction process in the leacher with air agitation through the virtual reality system, the students raised by themselves several questions like improving the agitating condition, an important factor that affects reaction rates, that is, the relative position between the circulating pipe and the air inlet and the ratio of the diameter of the inlet and the circulating pipe to the diameter of the leacher body. While finding ways to solve them, they were able to raise their ability of application and self-study.

“Structural engineering of thermal facility” is a subject which studies theories and techniques related to the design, fabrication and structural safety of thermal power facilities.
In the past, the cognitive faculty and the level of 3D design and structural analysis of students were low due to the lack of concrete images of thermal power equipment.
Pak Un Hyok, a researcher at the Faculty of Heat Engineering, has introduced practical 3D models and applications to his subject to ensure high cognition effect and application ability whereby students could satisfactorily solve problems arising in reality.
Firstly, he has presented practical problems for their individual tasks and asked them to solve them by using application codes.
Secondly, while giving theoretical knowledge, he has taken some minutes in his lecture to explain solutions to practical problems by application codes.
With a brief introduction of the mathematical induction, he has given detailed explanations of the ways of solving problems by ABAQUS and the results so as to enhance students' cognition and application faculty.
Thirdly, for better cognition effect, he has created, collected and edited real objects and models of ordinary thermal power facilities.
All these have proved useful in increasing the teaching intensity and the creative thinking ability of students.

“Device Driver” is a subject which deals with design technology of a program controlling peripherals connected to a computer system and interfaces.
In the past, when they taught general structures and programming methods of a character device driver, a block device driver and a network device driver, teachers failed to refer to individual devices in close combination with a control program. Without suitable examples found in reality, students confined themselves to getting a general understanding of the programming method, far from gaining knowledge of devices used in practice.
Kim Kuk Song, a researcher at the Faculty of Information Science and Technology, has associated his subject “Device Driver” with an embedded system, thus overcoming above-mentioned shortcomings.
First, he presented the information about Linux device driver of the embedded system in his teaching plan and gave specific examples in order to raise cognition effect.
As a device driver depends on I/O management of the operating system, he gave a general outline of the functions supported by Linux kernel in each section and explained with concrete examples which devices of the embedded system needed such functions.
Second, he organized practice hours in a way that students could consolidate what they learnt in lectures and develop their skills whereby they could write device drivers needed in reality by themselves.
The practical teaching content helped students understand how to write a device driver, but it still left those with lack of experiences with difficulties in practice.
Therefore, he applied a teaching method to help students to plan, design, make and control device drivers by themselves.
The first thing he did was to decide practice tasks for students to put their knowledge to practice and to show how a device driver worked in an embedded system so that students would be aware of the scale and capacity of a design object and the technological requirements to be solved. The next thing was to provide them with up-to-date data related to an embedded system so that they could select properly by themselves necessary handbooks, drawings, electronic circuits, example codes for a device driver, etc.
Until a device driver was finished, he repeatedly explained the building of cross development environment, translation, debugging, porting and downloading of source codes to the embedded system, and running methods.
As mentioned above, theoretical teaching contents on I/O management in an operating system combined with the structure and operation of peripherals and a device driver for controlling them and display of the operation of a device and a driver based on an actual one raised cognition effect among students. Students could develop their ability of utilizing the development kit for an embedded system while trying to develop device drivers by using a computer and an embedded device.

Pak Kwang Ok, a lecturer at the Faculty of Distance Education, has invented a new teaching method for improving the students’ cognition in which engineers from factories give explanations on specialized knowledge for production sites on a priority basis in a popular style in accordance with the characteristics of online education for working people.
Firstly, the main lecturer is responsible for giving theoretical knowledge and the important parts which are of value in practical use are explained in detail by the engineer.
The lecturer and the engineer discuss teaching contents and make a script beforehand so that students can get a sound understanding of theoretical and practical knowledge. On the basis of it, the main lecturer is in charge of the theoretical parts, whereas the engineer teaches the technical parts that are applied in the reality.
Secondly, mutual response between the lecturers and students is guaranteed.
She makes teaching scenarios by adequately reflecting the question and answer with virtual students.
That has proved effective in helping students acquire both theoretical and practical knowledge at the same time.

“Expert System” is a subject that studies different methods of designing and developing Intelligent Systems for simulating the ability of an expert. It is closely related to different subjects including “Artificial Intelligence” and “Knowledge Engineering” and it has a wide range of application and a great diversity in designing.
Such characteristics of this subject caused some problems with raising the students’ abilities of systemization, generalization and application onto a due level.
As it was important to remedy such shortcomings, Kim Ok, a researcher at the Faculty of Information Science and Technology, has applied mind mapping to her subject to enhance students’ self-learning abilities and creativity.
As a result, there has been a radical improvement in the students’ learning methods and in the cognitive abilities and creativity for developing intelligent systems.

Class discussion plays a very important role in improving the writing and presentational skills of students.
Yu Un Ju, a researcher at the Faculty of Management of Industrial Economy, has successfully improved their presentational skills by arranging heated discussions and arguments among students.
First of all, she makes clear the points to be discussed in the next discussion class.
Considering the characteristics of the subject, she gives every student different questions and lets them take part in the discussion with enough study.
Sometimes it is impossible because students outnumber questions. Therefore, she puts students into as many groups as the number of questions so that the students in the same group can decide by themselves detailed topics on the same points.
As a result, every student tries to make a detailed study of their points in combination with reality rather than copying others.
In addition, she confines presentation time to 5 minutes so that as many students as possible can give presentations in 90 minutes. Thus, students get rid of the outdated idea to fill their presentations with unnecessary contents and instead they try to think and study more deeply to give clear presentations in a short time.
Secondly, she changes the way of presentation and evaluates it accurately.
She encourages students to give an appealing presentation with their own words instead of reading the text at the desk as if they gave a lecture to other students. This makes students master their points and even those who lack presentational skills competitively run to the teaching desk with confidence, leading to animated discussions and arguments.
She evaluates students’ presentations with the main aim to fire the zeal of discussion. Mark is one of the means for making students take an active part in class discussions.
She has the result of discussion and presentation of each student evaluated by other students, not by the teacher. All the students listen to the speakers carefully and then express their opinions and give marks for each presentation. Every student puts themselves in teacher’s place, gives their own good views and has a heated argument. This has brought discussions and arguments onto a higher level.
