Theme 1: Research publications/Theory of science


Research Journal/Paper

I chose the journal Computers & Education. It contains papers about the educational use of computers and concerning subjects. The 2011 impact factor of the journal is 2,621.

From the same journal, I chose the paper What drives a successful e-Learning? An empirical investigation of the critical factors influencing learner satisfaction. Its goal is to identify critical factors ensuring successful design of E-learning. The authors use 13 hypotheses which cover learner, instructor, course, technology, design and environmental factors. These provide a basis throughout the paper.


I think that the 13 hypotheses they used were too general and were not very concrete. Due to the hypotheses, the conclusions were also a bit too general and not concrete enough. The 13 hypotheses were answered with “yes” or “no” in a final table regarding if it was significant for E-learning. For example, they concluded that course quality was significant. I think that this is pretty obvious and maybe not such a vital hypotheses to have in your paper in the first place. A great use of methods were somewhat wasted due to the lack of useful hypotheses. Despite the discussion part in the paper I believe that there weren’t much deep knowledge being presented. The paper serves best as a comparison between the 13 general hypotheses and not so much a presenter of innovative critical factors for E-learning, as was told. Improved, and not so obvious, hypotheses would have made the paper much better, since I feel that they made the whole paper too general and not very applicable.

Russell's book

1.
Russell explains that what our senses acknowledge as objects actually are our minds receiving sense-data of them. We are not acquainted with the physical object, but merely the sense-data of it. These sense-data are different for every person and depend on how we experience an object. All our different senses are affected by where, how and under which conditions we are experiencing an object. I believe Russell introduces this term because it is important to know that it is in our minds that we create an understanding of an object, where we (after receiving sense-data) take physical laws and pre-known knowledge into account.

2.
Propositions are known to us by knowledge by description. That means that we are not acquainted with the object in the proposition and therefore do not really know the truth (facts) about it. What we do know (have facts about) is things regarding the object in the proposition, since we might be acquainted with these. Propositions with “a priori” knowledge can be true without us having experience of it. A statement of fact is something experienced and acquainted with, which has led to a belief. If the belief corresponds to some fact, that believe is true.

3.
Russell defines “definite descriptions” as words or sentences describing a specific person or object (“the so-and-so”, as he mentions). Sentences like “the president of USA” or words like “London” are examples of definite descriptions, as they represent specific things. Definite descriptions are things that you have no knowledge of by direct acquaintance. The knowledge comes from acquaintance with things regarding the object, which could be acquaintance by sense-data, memory, or texts read about it.

4.
The philosophic and scientific views of knowledge do agree in many cases. One example where they did not is where philosophers primarily thought that nothing was infinite, until science proved that time and space could be looked upon as endless and infinitely dividable. Philosophic knowledge isn’t exact. Russell mentions that one opinion alone doesn’t make something true knowledge, but that many matching opinions make knowledge more probable.

1 kommentar:

  1. I believe that the main question "What drives a successful e-Learning?" may be too broad and uncertain in the first place. Perhaps that´s why both the hypotesies and the conclusion as a result of these became excessively general as well. During our bachelor thesis we were told that one of the most important things is to minimize the main question, obviously because it makes it easier for us to answer our own question. That may be the big issue here. The author can´t really answer his question in a good way because of the uncertainty.
