Terese, I think you've found an interesting article, but I'm confused about the possible hypotheses of this research. Why should they study how individuals use their human and social capital in the game, if results are not to be implemented in real life? So I cannot clearly see how theory corresponds with the data.
Susanne,
I like your example with Fanta, it was really demonstrative.
I was also quite curious about your article, so I've glanced through it. I hope you meant this article, just to be sure: http://www.informatik.uni-rostock.de/~ct/pub_files/Aigner08TimeVis.pdf
I wonder why you believe that EP theory is used there, not theory for action and design, since it is an empirical study with a great practical value/recommendations?
I'm not much competent in the visual analysis field so it is interesting to hear how you engineering student assess the paper.
Diana Imamgaiazova9 november 2012 11:19
Kunthika, I like your choice of paper, I think that copyright law is a really important problem of today. But I couldn't find in your short summary does this paper contains explanation of "WHY copyright law isn't supported by social norm?"
Diana Imamgaiazova9 november 2012 11:29
Sandra, I also think you've found a paper where the theory is used in an exellent way. I wonder if author of the article mentioned what kind of application this theory had had before present study? I guess there might be interesting studies on how people were accepting computer/telecommunication technologies which use this theory too?
Diana Imamgaiazova9 november 2012 11:39
Sandra, it is interesting to read how you can find an application of abstract theoretical concepts to your practical work. Could you tell a bit more about your thesis? What kind of methods do you use to "collect knowledge from the users and about users"?
Diana ImamgaiazovaNovember 9, 2012 8:56 PM
Lars, the theory of 5 parameters of cultiral properties is really intriguing. As I understood it isn't original theory developed by the authors themselves? How did they come to idea to use it for analysis of commercials/advertisments and how they justify this approach?
Diana Imamgaiazova9 November 2012 21:06
Bridget, I like that you found this theory interesting and probably somehow useful for you.
I also thought about your theory... could you understand from your paper what is the difference btw these 2 theories:
- Technology acceptance model (TAM)
- Unified theory of acceptance and use of technology (UTAUT)?
Is the second one is more integrative?
iana Imamgaiazova9 november 2012 09:10
Johan, I like how you managed to write really short abstracts from both articles. Don't you find that second study lacks a qualitative analysis of collected data?
Diana Imamgaiazova9 november 2012 09:21
Carl, what was your own expirience of online learning? Could you propose another method of sampling (based on your expirience) which could be relevant? Personally, I think that pure qualitative methods of Zembylas' research mentioned in the paper are more relevant (he used the interviews and monthly diaries).
Diana Imamgaiazova9 November 2012 18:39
"Maybe it would have been suitable to point out specific pros and cons for qualitative respectively quantitative methods in order to motivate why the mixed research method is the most optimal one for online learning"
Emma, I think it's a really fair comment. Through authors have discussed some disadvantages of quantitative studies (focus on quantitative comparison of online learning results with traditional learning), they don't really give enough of examples.
Could you think of some pros and cons for pure quantitative/qualitative approach in regard to your topic? Would you prefer to conduct a mixed research?
Diana Imamgaiazova9 November 2012 18:59
Fernanda, I also like your example from TBBT =) How do you think what type of theory Sheldon has developed and tested (by Gregor's classification)?
Diana Imamgaiazova9 november 2012 10:26
Philip, I very much like this note:
"Now, one could argue that if you actually are into education research, you wouldn’t have any problems understanding this article. That is probably true, but then, how can you get “into” education research if all papers are written in a way that prohibit newbies like me from understanding them".
It reminds me abouth this theory of Michel Foucault that scientific discourse is designed to be incomprehensible for outsiders in order to prevent the widespread distribution of knowledge (even if scientists claim/believe to be concerned about easy-access to education).
And coming back to the topic. If I correctly understood the last 2 sentences of your entry: in your opinion, empirical research can not be a mixed research in the same time. Why?
Diana Imamgaiazova9 november 2012 11:04
Mikael, if we consider your evidence about mixed approach as the most popular among the students in your program (or you were talking about students from KTH in general?), don't you think that this approach is just more common in your field than in educational studies, for instance? I think researchers don't use the mixed approach in quite many disciplines.
Diana Imamgaiazova9 november 2012 12:26
"After all the study is based on a survey and can thus only measure a short timeframe of inputs, perhaps the first response?"
Viktor, I agree that the second-wave survey of questions (postponed survey) could provide some valueable data, but researches try to avoid the subjectivity in assessment by using other sources (such as transripts of online conferences). How do you think this source can be reliable for study of emotional presence when researchers only have access to the transcript, not to the record of conference?
Diana Imamgaiazova14 november 2012 13:53
"And so the method is something that is explained in retrospect rather than chosen from the beginning"
Joel, I agree with this notion of yours. Also why do you think that mixed research design is more demanding? I believe that sometimes spent resources can be comparable.
Diana ImamgaiazovaNovember 14, 2012 11:20 PM
"It was mentioned during the lecture as well that two types of validity are internal and external. As of now, I am not quite sure yet about what internal and external validities are."
Cheatana, it was not easy for me too. But lately I've figured out that they related to 2 general goals:
1) to find out the correlation btw variables in our experiment, and prove that changes of dependent variable are only connected to independent variable, not to other factors (this is internal validity);
2) to extend these results to all the objects of this studied class/population. If our findings are true for the whole class of similar situations/objects then we call it "external validity".
That's how I understand those terms. And you?
Diana Imamgaiazova14 ноября 2012 г., 14:33
Mary, always nice and inspiring to see your enthusiasm in learning in spite of difficulties =) I have quite practical question: how did you manage do get a copy of SPSS? Is it open-sourse program or we have some kind of "free license for students"?
During our lab the program worked fine, but I would like pratice it a little bit more too.
Diana Imamgaiazova18 november 2012 13:30
Kunthika, the article you've chosen looks really thorough and well-planned. But I too have doubts about the possible influence on consumer behaviour because of the researchers' presence. I know about similar studies conducted with special devices which can registed media usage in real time and then incript data and store it. Some of them is stationed devices (like "peoplemeter") and the some are mobile devices (those designed to registed radio consumption for instance).
Why here researchers choose this method of real time observation instead of usual practice with devices, how do you think?
Diana Imamgaiazova18 november 2012 14:00
Nicklas, good choice of acrticle! It's really great that you've found some "how-to-do" explanations in your paper. Have you learnt (from this article or elsewhere) how to formulate questions for qualitative studies in a good way? I guess open-ended questions are really demanding and sometimes I'm really confused about them being a respondent.
Diana Imamgaiazova18 november 2012 14:18
Mariam, I like your choice of article, quite peculiar experiment is described here. It's sad that you didn't mention findings. Could researchers prove the hypothesis that avatar effects on the behaviour online? Actually, it isn't clear for me how could they evaluate the degree of avatar's influence. For instance, in second part with KKK-userpics. All the participants anyway have different temperament and more or less like to tell the bloody stories, so how we know if the avatar made a big deal about the content of story or not? In other words, how they prove internal validity? :) Did they make every person to tell the story twice under different avatars (if yes, how then participant can't guess the purpose)?
Diana ImamgaiazovaNovember 18, 2012 11:38 PM
Cheatana, I think research described was really hard work for authors. I can't imagine how did they distinguish certain similar patterns of the subjective expirience of participants. But can we rely on the own judjements of participants? If I would writing about my expirience I could probably overestimate some positive effects and underestimate downsides. How this subjectivity can be diminished?
Diana ImamgaiazovaNovember 14, 2012 11:20 PM

Diana Imamgaiazova25 november 2012 11:23
Nicklas, in this study of your choice do researchers compare the results of individual computer-mediated learning with collective one? Or usual сollective practice in class with computer-mediated? Don't you feel that in this case the point of reference may effect on the results of the study?
Diana Imamgaiazova25 november 2012 11:32
Christian,
have the researchers performed the user study to estimate the "life-likeness" of avatars? What are the limitations of their study?
Diana Imamgaiazova25 november 2012 11:40
Miriam, it think the paper you've finally chosen is quite appropriate for the task and also really good one. But I can't get the scvenario in testing. Why do you think they use 2 different groups testing different technology instead of test both of the interfaces in one group?
Diana Imamgaiazova25 november 2012 11:50
Niklas,
I appreciate your explanation on prototypes and would like to pose couple of questions because you seem to be really familiar with the topic:
1) don't we usually call a "theoretical" prototype (like sketch mentioned by you) by name of "model" because it still only a conceptual idea of the technology? or sometimes the concept itself is already a prototype?
2) can we test a prototype without a user study?
Diana Imamgaiazova25 november 2012 12:02
Johanna, it's great that you have expirience with creating prototypes. Actually not all the students in our group did it, like me for instance :( So I'm wondering on which stage of project development it is better to test a prototype? I had an impression that you don't really test the algorythm/design from the very beginning? Or you test-and-fix it on every stage?
Diana Imamgaiazova9 ноября 2012 г., 8:45
Stefan, thank you, it was quite a flattering comment. Concerning your observation about theories built on the previous research. You are certainly right, I let it out of sight when I was composing this entry. I suppose this type of papers belongs to some high-levels of theoretical abstraction in opposition to those "middle range theries" based on some empirical data.
Diana Imamgaiazova2 ноября 2012 г., 11:12
Mary, as I wrote above, the theory of narrative and the structural theory of the meaning (generative semiotics of Greimas) are used by the author of the article.
Could you please elaborate on what else you understand by "theory itself"? I didnt mention the semiotic square because it is not theory itself, but a certain instrument used in the framework of this theory.
Thank you for your comment
Diana Imamgaiazova9 ноября 2012 г., 2:58
Mary, I use survey of questions.
Thank you for your question!
Diana Imamgaiazova29 ноября 2012 г., 5:08
Mary, you question is adressed to the paper of my choice, right? :) I think the research could be complemented by other methods only on the following stages of this technology development.
Diana Imamgaiazova29 ноября 2012 г., 6:48
Emma, I guess that it is more like the theoretical framework is designed to cover the broad field of studies, not like Jenkins is just a genius =)
I believe that modeling is a broad concept which may include such methods as:
1) Theoretical modeling: here you just invent smth in your mind, some concept of the technology that might be developed someday like the "space gun" in the novells of Wern. Today we have the science of futurology to invent such crazy ideas =) some theoretical models are also common in theoretical physics. The theorist Ukio Misima duscusses the opportunity to use the 4th dimension to travell across the galaxy and this is quite a theoretical *model* nowadays, not just a fantasy! I'm just fascinated by this type of models =)
2) Design modeling: here you develop a scheme on paper or electronic model on computer
3) Prototyping: here you develop a real device or working technology with core functionalities of the future product
Actually in case of IT and sometimes media technology the "design model" can be something quite similar to prototype. The significant difference may occur in construction/engineering and natural sciences.
This is just my thoughts after reading some books and papers and there should be more scientific typologies on this topic of course. But I think the theoretical models and real prototypes should be distinguished in the most of sources.

Bobby, I wouldn't use it by myself because I'm not a socker fan in a slightest. But friend of mine (the biggest fan ever!) already wants to purchase the app. He found it's going to solve some problems for him: now he is sad that he can't secretly follow the important games when he is at the meeting or date. =)
I can't see why you don't believe in video-conversations? I think it is a useful technology and people going to love it in future. I guess now our opportunities to use it is limited due to the high costs of mobile video streaming.
