Progress specialist IT knowledge among students based on learning blended learning

– The article includes the analysis of the course whose aim is to present the potentialities of the system of virtual education Moodle[1], which is the basis for constructing e-Student platform owned by State Higher Vocational School in Krosno. The article presents the use of e-learning in the course ‘Computer science in tourism’ conducted at the Department of Tourism and Recreation in State Higher Vocational School in Krosno. The analysis of test practical task and ﬁnal axam results computer science in tourism for the students of Tourism and recreation, which involved work in Voyager Travel, Hotel, Euroticket On-Line has clearly shown a strong correlation between the acquired computer science knowledge (good and very good grades) and the results of the ﬁnal semester exam in Computer Science in Tourism e-course. The article describes the observations and conclusions drawn from the computer science courses run with a portal system based on the Moodle platform in the State Higher Vocational School Institute of Technology.


Introduction
The very concept of E-learning, as well as academic courses as such conducted in this system, still raise a lot of controversy in the Polish system of higher education. Although it is less and less common to question the important role of information technologies can play in the educational process, quite a considerable part of academic teachers , due to the concerns about the quality of education, have a lot of reservations about the application of information technologies in distance learning.
at State Higher Vocational School. (SVHS) in Krosno. During the course two types of E-learning were used.
• Synchronous training -lectures conducted in the real time. The students communicated with the lecturer and the other participants of the training at the arranged time of the day. The subject matter of the virtual lecture was planned in advance during the classes run with full time students at SVHS in Krosno. The very training took from 1 to 2 hours ( it depended on the type of lecture). • Asynchronous training -it is the most common type of E-learning. The students on the portal worked at their own pace. The students( especially extramural ones) individually allocated the amount of time they could spend on the portal, resulted from their professional work and other duties. The contact with the lecturer was maintained via the forum and e-mail.
The whole computer science course Computer Science in Tourism was based on the following forms of knowledge delivery: • Text(doc., txt).
• Flash presentation, e.g. the description of Voyager Travel system.
• Instructions (installation of booking programs in tourism).
• Link to lecturer's www page with useful materials.
• On-line test for course participants.
• On-line chat for course participants.
• Internet forum for course participants.
The teaching tools implemented on the E-Student platform allow for the construction of courses in many different ways. It must be remembered, however, that the primary aim of creating a learning course is first of all passing on the knowledge. It means that you do not need to be an expert in every single element of the Moodle system to be effective in virtual teaching. This constitutes an incentive to use the possibilities of E-Student platform in teaching.

The propositions of the analysis
Below are presented the patterns of student participation in elements of E-learning during the testing of groups. Pattern 1 (so called Strong Links) was prepared on the basis of the analysis of about 100 students (full time/extramural studies), who, in percentage terms, spent more or less time participating in the course Computer Science in Tourism. This group includes all the students who participated in all the components of the course and covered portions of material ( computer systems in tourism) with the Pobrane z czasopisma Annales AI-Informatica http://ai.annales.umcs.pl Data: 28/07/2023 17:54:20 U M C S grades ranging from 3.5 to 5.0. This had a strong impact on the final grades in the practical exam in computer system at the end of the semester.
The group of so called "Weak Links" was a group of students who did not manage to handle all the electronic materials in the course which were made available to them by the lecturer. Those students' grades were between 3.5 and 4.0. It had a considerable impact upon their final exam grades. The students in this group did not participate in the discussion forum, chat and did not ask many questions via e-mail. Neither did they make use of electronic materials, such as lectures (text, multimedia presentation).

Analysis
The analysis of the two singled out groups of students makes it possible to draw several conclusions and confirm the research hypothesis made before the E-learning course.
Firstly, a full participation in the course ( installation of computer systems in tourism, using program instructions, studying lectures, forum, asking questions, chat skillsharing ) had a huge impact on final grades, both in the case of getting credits and passing the final exam.
Secondly, all the gaps in the theoretical and practical knowledge ( selective use of E-student portal) is strongly correlated to the knowledge acquired during the course i.e. vocational education of students of Tourism and Recreation Dpartment.  In preparing modules of material for the course Computer Science in Tourism I employed my five year experience in running an Internet educational page with practical tasks, lectures and presentations for the students of several SHVS departments, which involved such courses as "Computer Science", "Computer Systems in Managing the Information in Tourism" or "Computer Systems".
Making use of the experience in operating the educational portal for 5 years (www.robraj.pwsz.krosno.pl) I must say that the presentation of the material in the form of Internet page may not meet the requirements of modern E-learning training.
It is no longer enough to present the elements of the training in the form of the text accompanied by a picture or to give step by step instructions how to install a computer program (e.g. Kameleon or Hotel 2009). It is necessary to make available to students, for example, short oral briefing, fragment of a brief educational film or discussion forum. There should be steps taken to make so called "on-line assistance" available for each participant of the training or course . It is also necessary to secure the synergy of the whole course. It is also crucial to respond to questions appearing on Pobrane z czasopisma Annales AI-Informatica http://ai.annales.umcs.pl Data: 28/07/2023 17:54:20 U M C S

The problems of implementing E-learning course
The teacher of the course, while designing the course Computer Science In Tourism encountered a number of problems or difficulties which may appear in circumstances similar to those in which this from of education was introduced at State Higher Vocational School in Krosno.
(1) Technical problems. Technical problems are all kinds of limitations in access to the Internet that were encountered by the students selected for the course. Not everyone had an opportunity to participate in chat or discussion forum at the stage of "synchronous" training.  The second kind of problems, concerning time and place, was connected with limited opportunities (extramural students in most cases) to participate in so called "synchronous" form of E-learning at particular time or days of the week.
The problems of purely "human nature" are nothing but involvement or lack of it in the e-learning form of the course that I conducted.

Conclusions
This article presents the use of e-learning in the course 'Computer Science in Tourism' conducted in the Department of Tourism and Recreation at State Higher Vocational School in Krosno.
After two semesters of teaching, the system: portal system» E-Student-studentteacher» the relations in the system as well as grading system, its content and forms were analyzed. Conclusions concerning students' work in the system, teacher's work and his method of assessment make it possible to classify that kind of tool as an effective way of supporting the teaching process.  There has been a lot of research done to assess the effectiveness of E-learning. It is not my aim to prove that effectiveness. My research was aimed at verifying the knowledge and computer skills on the basis of specialist computer systems on the tourist market. The specific objective was to investigate how the implementation of varied forms of presentations influenced the quality of teaching in this department. The other specific objective was to assess the influence of increased amount of time spent on the portal, intensity of exchanging comments on the forum and chat upon the ability to operate booking systems in tourism. On the basis of test and practical tasks results among the students at the department of Tourism and Recreation and the final exam in the course Computer Science In Tourism, which involved working with Voyager Travel, Euroticket programs OniLine, the following conclusions have been drawn.
There is a clear correlation between the acquired knowledge in computer science (good and very good grades) and the final semester grades in the course Computer Science in Tourism.
Within four semesters, the research covered around 250 students who participated in two computer science courses.
The theoretical and practical knowledge was tested with sets of tests, sets of practical tasks and questions in the final exam in a given subject. Each group had the same sets of questions and tasks.
The difference was that group A and group B acquired knowledge in two different ways. Group A did test tasks, computer problem tasks with the use of SHVS Krosno estudent portal. Group B, in turn, had no access to the portal. They acquired knowledge through participating in classes ( just like group A) but other areas of knowledge were acquired by them in the way they chose (consultations in the laboratory, library, reading hall, the internet).
The analysis of the practical exam results proved that granting students access to the portal through preparing so called problem tasks allowed the students in group A to acquire knowledge much more effectively than the students in group B.
It should be stressed at this point that the time devoted to group B students was longer by 1/3 as compared to group A. The participants for the two groups were selected at random. In order to confirm the hypothesis the analysis was checked again in the current academic year. The hypothesis was confirmed. Again group A turned out to be a group of "Strong Links", which was exhibited by active involvement in doing tests, short quizzes, and problem tasks.
The effectiveness of the conducted on-Line course, as exemplified by the course Computer Science in Tourism consists in the following elements: • Acquaintance with the course participants' knowledge, their consultation needs. • Constructing a course with clearly defined objectives and getting the students at the Department of Tourism and Recreation acquainted with them. • Paying special attention to the graphic layout of the course; graphic layout should facilitate navigation and learning. • It is necessary to take into consideration students' actual skills, like operating a computer, and in the case of using audio and video files or web pages links taking into account the equipment constraints. This paper presents the analysis of the implementation process of e-learning platform E-student, the aim of which is measuring the effectiveness of the teaching process in the Department of Tourism and Recreation at State Higher Vocational School in Krosno. The reasons for carrying out such an analysis are growing expectations of employers towards our school's graduates and information technologies inevitably entering every field of human activity, including travel offices, tourist information offices and others.
At the same time, the e-learning system, which is based on a uniform teaching program in the department chosen by the author of this paper, would secure an automatic measurement of teaching effectiveness, much more extensive and faster than any of those found in traditional forms of teaching.
The research conducted by different scientific and educational institutions shows that e-learning is as effective as traditional methods of teaching. The teacher in e-learning is "virtual, that is, he does not have a direct contact with the student, it is not necessary to conduct classes at particular time of the day and the student can learn at any time convenient for him. The learners can adjust then the time of the course to their pace of learning, which, forces them to work harder and longer though.
In many cases, students involved in the traditional form of teaching ( extra mural students, in particular) wanted to have additional consultations at school, but it was impossible due to their duties outside school. The introduction of discussion forum and chat related to the course resulted in an increased number of queries, comments and skill sharing with the teacher.
The effectiveness of learning in the traditional model of teaching decreases with time if the pace of learning is imposed by the teacher, which has been proved by my observations while teaching in the Department of Tourism and Recreation.
Different forms of distance learning, supported by technical aids allow for more innovative means of transferring knowledge and provide new opportunities to modernize the schemes of selecting the teaching materials. E-learning, or teaching with computer is a challenge faced not only by the higher education in Poland (including State Higher Vocational Schools) but also by the Polish economy, for which the change of professional profile will determine its further progress in modern Europe.
