Final reflection

This is my final reflection in the course DM2572 Theory and Method for Mediatechnology. During the course we have discussed different topics, such as what is knowledge, what is theory and later more concrete subjects as quantitative and qualitative methods and case studies. In this final reflection I would like discuss the course first and then later discuss how to combine different methods in order to answer complex research questions.

How have I experienced this course?
Before taking this course I knew this was a course that contained a lot of reading and writing and which is in a way my biggest weakness. And combining that with the fact that it is in english made it even harder for me. During the course I have felt that it became less difficult in every theme. The first themes were much more difficult than the latter. I would say that the tipping-point came after theme 3 (even tho the theme for week 3 were less difficult than the previous two weeks).

One thing that I appreciate is that I’m taking this course after the bachelor thesis. I’ve read on others blog post that they have discussed the pros and cons with that order of courses. I see positive aspects of having the courses in that order since what we are talking and discussing here is more concrete for me now, and I can relate to the different methods in a way that I wouldn’t be able to if it was the other way around. And still, I can learn by my mistakes in my bachelor thesis that I now have detected, and correct those mistakes for when I’m writing my master thesis.

How have I experience the order of the themes?
In the beginning of the course we discussed what knowledge is, generally about critical thinking and what theory is.  As I said above, these topics has been hard, for me and I guess everyone else as well. I can’t really see how the two first themes are related to theme four to six, but I guess they have made us stand on a solid ground in order to be able to discuss the more concrete topics (such as quantitative, qualitative methods, case studies etc.)  otherwise we would just scratch the surface of those topics.

How have I experienced the course structure?
The way the course has been organized feels like an optimal way of organizing such a course. I specially liked the continued examination these blog post has represented. And the rolling schedule has made it easier to come up with a studying plan for this course. To write own and read others blog post have been a nice way to reflect my own thoughts and read how others have interpreted and understood the different topics. Unfortunately I didn’t realise we were suppose to comment on each others blog posts and therefore I kind of rushed through some of the other course students blog posts at the end of the course, which perhaps was not optimal.

It is funny to see that many others interpret and payed attention to other parts of the lectures than I did. In the first themes we were talking about how different people percept different things in different ways, and I think the blog posts is a very good example of that. Perhaps I find one little detail about quantitative study more interesting than someone else does, just because I have maybe used that in my bachelor thesis. We all percept lectures in different ways depending on our past experience, and by reading the blog posts you can get a glimpse of how others sees the lecture and the key points.

Combining different methods in order to answer complex research questions.
Now I would like to discuss the different methods and how they can be combined in order to answer complex research questions.

First I would like to repeat what Haibo said during his lecture. In order to conduct a research paper, or solve any problem in general, you should focus more of the time on defining the problem than a person usually does. When you have defined the problem correctly the problem solving will be much easier. It is easy to interpret a problem as much bigger than it really is, and in order to find the “real problem” which might be only a part of the first thought problem it will eventually save you a lot of time and effort.

What I have learned regarding different methods during this course is that they all have pros and cons, and they are suitable for different purposes. Unfortunately I couldn’t attend to Eva-Lottas lecture about collaborative settings, but I understood from reading others reflection from that lecture that when you are doing a research in an area that is not well explored you should use qualitative methods in order to get a little understanding of the area in question so that others research can build upon your results. This statement states one of the pros with qualitative methods, that it gives you an in-depth analysis of a subject, but more importantly the statements says that other research can build upon you results. I find that interesting since when you are doing a research of an area, there most likely have been researchers that already have explored some part of that area previously, and you don’t want to re-explore the same thing as they have done, therefore you want to do something else, perhaps change what kind of method you are using. When you are not using the same method as the previous researchers have used you will get an different perspective of that area/object and that proves that you need to use different methods in order to get different answers and when combining different methods you can answer more complex questions and discover, more fully, an object and by combining different research papers, the area will be more explored.

In the first theme we were asked to describe what Kant meant when he said “Thus far it has been assumed that all our cognition must conform to objects. On that presupposition, however, all our attempts to establish something about them a priori, by means of concepts through which our cognition would be expanded, have come to nothing. Let us, therefore, try to find out by experiment whether we shall not make better progress in the problems of metaphysics if we assume that objects must conform to our cognition.” and as I interpreted it we need to see the object from another perspective. This can be related to how different methods can be combined in order to answer complex research questions. Every different method gives their own perspective, for example quantitative method gives you an overview of the subject but can’t explain why a result pattern occurs and the qualitative method can describe why something is occurring but not what is occurring. To fully be able to answer a complex research question you need to use different methods in order to get different perspective to fully understand and be able to fully answer a complex research question. Every little method has their own pros and cons, which we have discussed during the seminars, and by combining the different methods they are filling the gaps of each others disadvantageous.

The most obvious example of combining different methods is to combine quantitative and qualitative methods in order to get an understanding of what (for example) people thinks (quantitative result) and why they think like they do (qualitative result). But everything is not just surveys and interviews, sometimes you need to conduct a design research study in order to find how a prototype works and combine that with qualitative interviews to fully understand the prototype. Sometimes you need to conduct a case study to understand a phenomenon with the help of qualitative and quantitative methods. They are all linked to each other and therefore it is perhaps wrong to nominalisticly see them as separate methods and instead see them as tools that are alike but with some different properties.

Finally I would like to thank for this course and I hope I will remember much of what I’ve learnt to be able to write my master thesis in a good way.

My Comment:

I also tried to translate every single word in Kant's text to try to understand what they meant but didn't succeed.

Regarding the lecture, I found it hard as well but I don't think it would be much easier if it were in Swedish. This is a difficult way of thinking.

When you are saying "knowledge requires knowledge", do you think that experience is the same as knowledge? because i think knowledge requires experience.

My Comment:

Interesting to hear about the newborn child (he didn't mention it in my seminar group). I remember that he said that one time he woke up, because the phone rang, and he didn't know where he was, who he was and what the sound came from and meant. He had, in a way, lost all his experience of life for a second and I think that all of us have sometimes felt the same. I think that's how it feels like if you are seeing WITH your eyes and not through them.

Also glad to hear that it wasn't just me that interpreted kant's text "wrong". :P

My Comment:

I also finds the expression "You can't see the forest for the trees" as a good expression for nominalism. We discussed in our seminar group about the difference in how Nazi sees people, and how communists sees people. Nazis compare people as strong, long, fast, white etc which enables them to compare and prefer some sort of people which is a nominalistic way of seeing people. on the other hand communists see mankind as a group of people which they can set a "human"-label on. Nazis are seeing the trees and communists are seeing the forest.

I think that you are explaining the key points very well and you summed it up in an understandable way! I also found Plato's cave to be a very good example and a illustrative example. It gave me a better understand of the concept, which I didn't understand when I read the texts. It was interesting to hear how to applicate this to the was Nazi-germany used their propaganda films.
Good Job!




Theme 3
Johan Huusmann
My Comment:

Hi Johan

I also found this week much more concrete in a way, but still abstract in a weird way.

Indeed its very hard to define the word theory and as you say the word can have different meaning for everyone. I like the definition that you are satisfied with, the bridge between raw data and hypothesis. But still, even if you have a definition its still hard to know what is a theory and what is it not, don't you agree?

I found it interesting when you said that the reason that the word theory might be hard to fully understand is due to the use of the common man.

Good reflection!

Cecilia Friström
My Comment:

Hi Cecilia
It sounds like you have really tried to understand the word theory, which is good. For me its still a bit abstract and I guess it will be, but when reading your text it somewhat clarify a bit for me.

I found it interesting when you wrote that when you are using the word theory in a non-science context, like a substitution for the word idea, it is not a valid or tested theory. But for me it sounds like thats not a theory, more like a hypothesis, since its not tested and confirmed, don't you agree? And when "non-science-people" use the word theory in everyday language its more like they use the word hypothesis.

Good job with the reflection!

My Comment:

Hi Oscar,

You said that you learned that you should test a questionnaire and survey before using it, I would like to hear how you are suppose to do that and if you learned any good method of doing it?

I also found the lecture structure good and it was nice with another setup, and not the usual lecture on monday and seminar on wednesday. Olle managed to keep up a discussion and still delivers tips and thoughts.

Keep up the good job!


Andreas Almqvist Gref
My Comment:

Hi Andreas!

I think that you manage to reflect upon the key points from this theme. To try you questionnaire before sending it to the responders are indeed crucial since you might be blind to your own mistakes.

I was thinking of the benefits, disadvantageous, possibilities and limitations that you mentioned, i would like to hear an example of a thing that you didn't know and learned on the seminar. According to me, most of the was kind of obvious, but still they are aspects that you normally don't think about, and then they was more highlighted than new knowledge.

Combining quantitative and qualitative methods are indeed useful!

There are indeed many psychological factors that you should consider when desiging a questionnaire. I thought it was interesting that Olle said that When you are designing a questionnaire, you should, or must, have an alternativ that are "in the middle" otherwise the responders get angry. I thought before that it was good not to have that alternative because people then had to reflect more and not just give the easiest answer, but i was wrong.

Good job!

My Comment:

Hi Zulfiia
This was a good recap from the lecture but I have a question:What did you know before you went to the lecture and what did you learn during the lecture? It would be fun to hear that.
I found it a bit confusing when Haibo said that big ideas and great ideas are ideas that generate money, like you wrote. But surely there are ideas that doesnt generate money and still are good ideas. Do you agree?

Noa Julin
My Comment:

Hi Noa
I couldn’t attend to Eva-Lottas lecture and therefore it was fun to read your reflection of that lecture. I first thought that when a research is made in an area where there are no previous knowledge you should use quantitative methods in order to get a glance over the “area” or subject. But, as you wrote, Eva-Lotta thought you should use qualitative methods. Which one do you think is best for the purpose? (I guess the combination would be best).

I found that the volume example that Haibo gave in order to highlight the importance of math is a good example too. It’s easy to misinterpret a situation if you only believe your senses, and therefore math is important in order to understand the results. Good that you highlighted that part if the lecture.
 

Theme 6
Johanna Sjöberg
My Comment:

Hi Johanna
I think its interesting that you are saying that you don't need to know what you are looking for in the beginning of a case study. But you also says that one usually has an idea about what you are searching for. I think that mobility is very interesting and a huge benefit of a case studies.

Its good that you can see both positive aspects and negative aspects of having this course after the bachelor thesis. I think its good to have it between the bachelor and the master thesis since, as you said, the things that we are reading about in this course makes more sense after the bachelor thesis and you will detect your mistakes that you have made and adjust them before the master thesis

By the way, good reflection!

Sofia Sjöberg

My Comment:
Hi Sofia

You said that we already know much about qualitative study and therefore it was good that we mostly focus on case studies, but did you think the same way about quantitative methods (?), that we already knew things about it. I did at least, and still I learned much about quantitative methods from the seminar with Olle. Don’t you think it would be the same with qualitative methods as well if we would have payed a lot more attention to it?
Its interesting when you are saying that a case is not created, it’s already there. The difficulty with it, is to understand what’s a case and not. What made-up case are and what existing cases are is in a way an interpretation of a phenomena made by man. I mean most of the cases that exist is once made up and defined as a case. One question that occurs is what is it that creates a case?

I agree that it is hard to determine whether or not a research article has used case study as a method since its a notion of nuance.

Great reflection BTW!

Theme 6 (post)

Postreflection theme 6
This weeks theme was mainly about case studies. In the seminar we discussed what a case study is and I think that I understand what it is, but still it's difficult to say if a research article is a case study or not. I think that's because it is not just "a case study" and "not a case study", there's something in between.

One thing is clear, you need to have a specific frame, both for you target group and the topic that you are examine. And it has to be a naturally made frame, not a boundary that you've made up for the sake of the research.

The paper that i read for the pre reflection was a case study about how bootlegging has affected the music industry. And now after the seminar I think it was a pretty poor case study since it was more a description about the case and didn't make any effort in trying to be theory-generating. And it only contained one type of method (qualitative semi structured interviews). As I understand it a case study should (or atleast it's common that it) contains more than one method.

The qualitative research paper that I read sound more like a case study to me. It had a fixed target group (20-28 years ICT users with symptoms of psychological disorders) and the case was about how they believe they are affected by ICT use. And they combined both a quantitative study (that was conducted before this article was started) to select the participants and the qualitative study (interviews).  But its a fine margin what a case study is and what a case study is not.

Theme 5 (post reflection)

Theme 5 post reflection
This theme was supposed to be two lectures, one by Haibo Li and one By Eva-Lotta Sallnäs. Haibo’s lecture were moved to today (13 oct).Unfortunately I couldn’t attend to Eva-Lotta’s lecture but I heard that she talked about her previous studies in the area of haptics and collaborative research, and I think it sounds like the texts we read, written by her.

Haibo’s lecture was about how to get an idea to a successful prototype. He divided the lecture into five steps:
  1. How to come up with an idea. (Define the problem)
  1. How to filter ideas. (business mind, which idea has a great potential?)
  2. How to validate an idea. (Proof of concept, math)
  3. How to evaluate a media system (evaluate the usability: effectiveness, efficiency and satisfaction)
  4. How to communicate an idea.

He emphasized that it’s very important to define what the problem really are in order to be able to solve it. There’s often not just one way to look at a problem, and with a different perspective you might find a easier solution.

When it comes to filter the ideas, I thought that he were a little bit too “money-minded”. He said that a great idea= billion-dollar business, and a big idea= million-dollar value. Surely there are ideas that are great that isn’t worth a lot or generate a lot of money.

I guess I didn’t really learn that much of the lecture, this step-by-step overview on how to go from an idea to a prototype is kind of obvious, but it’s always fun to go to lectures with Haibo. One thing that I did learn was the importance of math when we are trying to understand research results. When I read research article I always finds the math and the statistical formulas boring and hard to understand, but I guess I’ll have to learn them someday in order to understand and interpret the results.

Theme 6 (pre)

THEME 6 (pre)
  1. Which qualitative method or methods are used in the paper? Which are the benefits and limitations of using these methods?
  2. What did you learn about qualitative methods from reading the paper?
  3. Which are the main methodological problems of the study? How could the use of the qualitative method or methods have been improved?
The article that I’ve chosen is “Perceived connections between information and communication technology use and mental symptoms among young adults - a qualitative study”. As the title reveals the article is about how ICT use can affect young adults in terms of mental symptoms, such as: depression, sleep disorder, stress etc.

The qualitative method was based on a previous quantitative study (which wasn’t included in this article). They got their responders from the quantitative study (a questionnaire regarding the same topic), where they had reported high ICT exposure prior to reporting mental symptoms. 44 individuals were contacted to participate in this study but some couldn’t attend, therefore 32 young adult participated (20-28 years).

The qualitative study included individual semi-structured interviews. They were asked open-ended question about possible connections between stress, depression and sleep disturbance and ICT (focus on phone and computer) use. An example of a question could like this: “Do you think there is a connection between the use of computers and stress? If so, how? Have you experienced that yourself? What about people in general?”. Parallel to the interviews a physician psychiatric assessments of the participants. The interviews were then sorted into different topics and thematic domains. These thematic domains were then studied regarding their relations between each other, finally a model were created that illustrates the connection between mental symptoms and ICT use.

It’s hard to find benefits and limitations with this kind of method since it’s a quite regular and straightforward method: gather participants that fits the subject, perform semi structured interviews, analyse the result and create a model/conclusion. The benefits of this method is the same as  for qualitative methods itself, which is that it gives a in-depth view over the subject. And the limitation can be that, since it’s a small group of people, it gives a reuslt that can’t be seen as representative for the whole target group.   

I didn’t learn that much reading this article regarding qualitative methods. But I think it’s interesting that they use both the semi structured interviews combined with a analys from a physician, as if they wouldn’t beleive in what kind of mental symptom the responders are experiencing.

I think the example question they presented in the text (the one above) is biased. They are in a way proposing, in the question, that there is a connection between mental symptoms and ICT use, which perhaps makes the responders answer in a positive way for the sake of the study. The author also wrote that he thought that the responders didn’t answer all question by experience but for the common thought of the subject. And since the question was kind of biased, the common thought of the subject might appear in a way that perhaps isn’t completely true.  



Briefly explain to a first year university student what a case study is.
A case study examines a event, organisation, behaviour, individual etc. It examines and explains the specific phenomena and gives examples and data from that phenomena that makes it easier to understand and analyze it. In the end it will give more understanding of the chosen phenomena, which can be appropriate for research areas that haven’t been explored yet..

Use the "Process of Building Theory from Case Study Research" (Eisenhardt, summarized in Table 1) to analyze the strengths and weaknesses of your selected paper.

The paper that I’ve chosen is “The effect of Piracy upon the music industry: a case study of Bootlegging” published in the journal “Media, culture and society”. The article discuss, as the title reveals, the impact that the bootlegging has on the music industry, with a main focus on the economic part. The author (Lee Marshall) first presents the object of the article and then try to define bootlegging and how that is separated from other kinds of piracy in the music industry. Then he discuss the positive and negative aspects of bootlegging on the music industry, with the help of citations from interviews that the author conducted with various bootleggers and numerous examples.

The biggest weakness of the paper is that he (the author) can’t come up with a real conclusion. He states in the end: “The overall effects of bootlegging are impossible to ascertain with accuracy…”  and continues saying that it both has positive aspects and disadvantageous upon the music industry. I don’t find it as a good case study since he can’t really answer the research question. That might be because he doesn’t have that much data or “evidence”. He just explains example how an artist might have been affected by the bootlegging community. I can’t see that he tries to analyze the examples all together and try to “wrap it up” in a way. Therefore, when looking at Table 1 in “Process of Building Theory from Case Study Research” I find that the author clearly fail to do the step called “Analyzing Data”

Theme 4 (post)

Theme 4 reflection

This week we didn’t have a lecture on monday but a workshop/seminar on wednesday. But I think it went pretty well because it was like a lecture combined with some sort of a fun seminar. With fun I mean that we played a game that was successful.

I learned a few more pros and cons with quantitative and qualitative studies. It was interesting to hear how other group thought.
The difference between a paper survey and a web based survey was even more interesting. I didn’t think that the difference was that big and that the choice of the medium in which you uses has that kind of effect on, at the end, the answer that you get. The biggest benefit with using a web based questionnaire is that you can make it interactive (like the example that Olle showed) which makes the responders feel that they get something out of answering the questions. The most negative aspect of web based questionnaire is that you only reach out to an uneven distribution of respondents, you have to have access to a computer with internet and be able to use it in order to be able to answer. This removes some generations (maybe) from the potential responders. The answer frequency is much higher for paper based questionnaire.

Another interesting thing was that when you are creating a survey, you should use a middle-answer-alternative, otherwise people get upset that it doesn’t exist and can exit the survey. I thought that it was good to force people to make a choice and that it would make people to reflect, even if they didn’t want to.

One thing that Olle wanted us to remember was a step by step guide for quantitative studies:
-Invitation via paper letter
-Paper survey or url with password
-Remember via mail
-Remember via telephone
-Remember via paper mail

PART 1
  1. How can media technologies be evaluated?
  2. What role will prototypes play in research?
  3. Why could it be necessary to develop a proof of concept prototype?
  4. What are characteristics and limitations of prototypes?
  5. How can design research be communicated/presented?

  1. The way I think that media technology can be evaluated is from thoughts and reactions from one of the user from the target group. It’s always hard to know how a person will interact with the product, you might think that they will use it in a certain way but then they don’t, those kind of evaluation I think is important for media technology.
  1. Prototypes is a huge part of researches. It is something that creates an idea into an object, which is obviously necessary to try an idea in practice. It’s hard to know and imagine how an idea will work if you don’t test it, and with a prototype it gives credibility to the research article. In Haibo’s text “Turn Your Mobile Into the Ball: Rendering Live Football Game Using Vibration” the prototype plays a huge part of the article, if they didn’t have a prototype the article couldn’t say anything about how it would work.
  2. It’s necessary to develop a proof of concept prototype to try your idea. You might have an idea of something which you don’t know how the target group will respond to, then it’s good to create a proof of concept prototype to try that idea before fully taking that idea into practice and creating object that no one wants.  
  3. The characteristic of a prototype is that it’s close to being the final product, but has some drawbacks, because it hasn't been tested enough. The limitation is that, since it’s not manufactured in a big scale, the prototype cost relatively much for being one object.
  4. The best way that a design research can be presented is through a prototype. With reactions and observations from the target group regarding to different aspects of the prototype. One thing that I think is a necessary part of the presentation of the prototype is to publish pictures and description of the prototype, so that the reader can understand the prototype and build up an opinion about it.    

PART 2
How does a collaborative setting differ from a single user setting as regards methodology used and the results obtained?
The simple answer is that a collaborative setting involves two or more persons while a single user setting involve, obviously, just one person. The result is more straight forward from the single user setting, because it’s just how that person thinks, acts, answers etc. The collaborative setting results contains more dimensions, and can result in a more in-depth result.
How can qualitative and quantitative methods in the same study complement each other?
Quantitative study can answer the question “what?” and qualitative can answer the question “why/how?”. For example in the text “Auditory feedback in haptic collaborative interfaces” Eva-Lotta and colleagues use a quantitative method to determine whether or not the auditory feedback made the task at hand easier and then they used a qualitative method to explain in what ways the auditory cues play a role for the collaboration in multimodal environments.  
How can using both subjective and objective methods give a better understanding of a phenomenon?
Objective methods are measurements and collecting of data. Subjective methods are ones thoughts, beliefs and experience regarding one thing. To better understand a phenomenon you need both collected data (objective) and you need to interpret those results with your own experience (subjective) to set the data into a context.
