Thema 2, Theory.


   The definition of the theory says that this is a teaching, a system of ideas or principles. The theory is a set of generalized statements that form a science or its section. Every conclusion in the theory is derived from other inferences based on the rules of logic output. The theory consists of hypothesis which is confirmed or approved through a survey or experiment. These hypotheses are proposed for the study or received as calculated for the known facts. Experience in the theory becomes meaningful and a source of meaning and knowledge. The theory includes the objective knowledge and cannot be the result only of the individual and subjective research. The objective but the abstract world is included in the theory. This world is represented by human-made objects such as mathematics, language, knowledge, science, art, etc.

   In the research “The nature of theory in information systems” by Gregor the theory is presented in the form of theoretical issues which are included in the four major groups of issues. Five major issues are: theoretical issues, structural and related issues, the epistemological issues and socio-political issues. Structurally the theory is divided into the following theories: analysis, explanation, prediction, explanation and prediction, intentions and prediction. The theory is considered to be satisfactory if it is considered by all of the types of questions and theories.

   Data, references, lists of options, diagrams and hypotheses are not theory. These concepts are supporting materials for creating the theory. The necessary data to the logical interpretation and comparison of data and creating theories are taken from these concepts.

   I have chosen the article “Impact of media richness and flow on e-learning technology acceptance”, Computers & Education Volume 52, Issue 3, April 2009, Pages 599-607.

   The article says about increasing of computer’s total part in the educational process. The number of computers is growing and the existing methods are not enough for the prediction of their share in the e-learning system. A combination of several theories for the research, understanding and forecasting the development of e-learning and multimedia’s part in it is required. This article creates an analysis of the possible solutions of this problem by combining a number of different theories. These theories study the information systems for training for students. In particular, the focus of research is the effective use of texts, video and audio materials.

   In my opinion, in this article the method of analysis and description are used. It can be seen on the methods that are used in the study and analysis of the results. The researches were conducted in different directions with several changes of the baselines. The conclusions made as a result of observations of participants of these researches. The practical advices based on the result of research and can be applied in practice. Also, this research can be used in the new possible theoretical researches. The results of this research can be considered in other areas where the streaming media is used.  

   The benefits of this method are the possibilities to describe specific phenomena. We can investigate the possible interaction between events and determining the capacity of these interactions. We can also predict the possible development of the relationship and the consequences of these structural studies. Limitations of the method include the ability to change the initial conditions of research and complexity of prediction of research of these changes.
