Reflections "after" / Theme 5
Design research topic was quite new for me. I
never read academic papers on this topic, so the structure and the development
of one particular idea were quite new and interesting for me. I found the
lecture on design research quite nice and (what is more important) applicable
to life.
During the lecture we discussed how to come up
with ideas and not only how to solve appearing problems, but also how to define
the problem. Professor Li gave us nice example of the case of the Hungry Bear
and we‘ve got an understanding that you can never solve a problem in a good
way, unless you have not defined it right.
The most interesting part of the lecture in my opinion is the discussion about “I have no great idea”. Because sometimes I feel it myself like having the idea, but I understand that it’s not a great one. Haibo gave us some advice how to start our own business – firstly, to validate an idea, get some sort of proof of concept, and even potentially get some customers, then to raise some money.

The seminar on design research I find quite
useful because it gave me the sense of structure (I love to have “plans” or
structures in my head, it puts in order my thoughts) what design research
represents itself. We discussed the fundamental principle of design science
research - knowledge and understanding of a design
problem and its solution are acquired in the building and application of an
artifact.
Then, we have been working in two seminar
groups discussing the papers and creating the scheme for each one. I found
pretty interesting the paper that Fernanda chose (despite it was pretty old –
from 2000) – about the Mobile
information and communication tools in the hospital where the researchers have developed mobile
digital assistant as a prototype - the system that examined the application fields of mobile communication in health care environments and then developed the system based on the study. I found the method – simulation study - quite interesting because it 'does not allow a
complete evaluation of technical systems, but rather aims to obtain design
proposals for a new technology from experts in the field and from future users' [1].

Reflections "before" / Theme 5
I
chose these two following questions because in my opinion this paper itself is
the perfect answer to both of them. It could become a great example for young
researchers who are developing design research and confused about evaluating
the results and presenting the idea.
How
can media technologies be evaluated?
I
think that this paper has one of the perfect examples of evaluation new media
technology. The researchers are applying their technology by checking 3 main
aspects of user usability: effectiveness (the possibility of accomplishing the task with the specific system), efficiency (that implies the quantity of efforts that are necessary to finish the task) and user satisfaction
(this aspect is evaluation the comfort of using the system). But researchers should be very careful and
pay great attention during checking and preparing users for such kind of
studies. For example, as it turned out, when the participants finished the
first experiment and started doing the second one, the researchers could think that they became more experienced (because they had been trained by the first
experiment). But the analysis
showed that the training had no influence on efficiency (but at the same time a significant effect on effectiveness). So it could be a very high potential of a risk of users being confused
by training.
How
can design research be communicated/presented?
The
paper could become a great example of presenting the design research work. The
paper is organized into 7 sections that make the subject clear even for people
who are not familiar with the topic at all (as me;-) [1]:
-introduction
of the main ideas
-design
guidelines along with necessary human touch perception issues
-vibrotactile
coding schemes for a football game
-explaining
the experimental platform along with system evaluation parameters
-presentation
of user studies
-detailed
user test results
-and
conclusions
In
my opinion the structure of presenting is very good - the main focus of it on
the experimental checking- the user studies, because as far as this paper is
presenting new media technology it should be evaluated to prove the quality of
it.
I
have chosen the high quality research paper “Social
Media Recommendation based on People and Tags” by Ido Guy, Naama Zwerdling,
Inbal Ronen, David Carmel, Erel Uziel IBM Research Lab.
In this design paper researchers invented a new application based on social recommendations within item recommendation within an business activity - set of organizations that includes blogs, bookmarks, communities, wikis, and
shared files [2]. The researchers propose a novel method for recommending social
media items based on both related people and related tags. This social software application suite includes seven main social
media applications that are being used: profiles (of all employees), activities, bookmarks, blogs,
communities, files, and wikis [2].
The
researchers evaluated their recommender system through two steps. Firstly, they
conducted a user-syrvey with the sample of 200 users that has been testing about 30 used and 30 incoming tags. They made it to explore the most effective way to build a user’s tag profile. Then they did an extensive user study
that eventually showed that it's very beneficial to use tags for social media recommendation.
The study itself was designed in a specific way - they tried to compare the people-based recommender (PBR), the tag-based
recommender (TBR), and two combinations of these two recommenders (PTBRs) [2]. As far as the evaluation
in this study is mostly based on rating an initial set of recommended items, I would recommend the researchers to try exploring the behaviour of users who regularly access the
system. It could be more challenging.

Last week studying experience was very interesting for
me. As far as I have some experience in qualitative research and I enjoy using
it when I am writing my academic research papers it was very interesting to get
to know about some new methods that I haven't explored in depth.
In our seminar group we have been discussing three
main qualitative methods: interview, focus groups and diary. When we were
editing the wiki-page of the course we realized that the main tricky question
that every researcher should ask yourself (it doesn't matter which method he
uses) is: "Am I sure that these people are really representative of the
society or the target audience you are aiming at."
Especially interesting discussion in our group
was about diary as one of the qualitative research. As far as I have experience
in conducting a survey about students' media consumption habits where they
should have had write a diary I can say that this method I'd really
time-consuming and the results often don't match the reality. People keep
forgetting about adding the information at the time they need to and in the
evening that usually don't remember all the details. And as Stefan fairly
noticed, if the researcher really wants to get good results, he needs to call
and remind people about it all the time and this is very tiresome and
exhausting. We also have been discussing another method - testing or evaluation
(in our case it was the game evaluation), but we were not sure that this is the
pure qualitative method.
During the lecture we discussed what is meant by
qualitative and empirical data, informed opinion, subjective experience and
objective knowledge, the role of time when studying technology and what make a
project become research. Actually, the lecture was more or less explanation of
the paper that we read so it was quite interesting to remember all main points.
Especially I found very interesting in-depth telling about semiotics -the study
of sign. As far as I am writing in my master thesis about Rolan Bart and his
theory of signs it was nice to hear some examples of signifiers and signifieds
in comics and fashion sphere. I was quite surprised with the comparison to the
programming code (because comics depict dynamic activities using a static
representation). But I found not very interesting the discussion of the paper
at the end of class, because in my opinion the questions were kind of tricky
and nobody could come up with the answer.

Reflections "before" / Theme 4
I chose the research paper “US
teenagers’ perceptions and awareness of digital technology: a focus group
approach” by Heather L. Hundley and
Leonard Shyles from the journal “New Media
& Society” (IF=1.394).
In my opinion in this paper authors are
perfectly applying one of the main qualitative methods – focus group. Focus
groups is one of the forms of qualitative research when certain group of people (it's better when it represents the target audience) is asked
about their ideas,
opinions,
concerns, perceptions, beliefs, relationships or attitudes to some services, products, ideas etc. The group represents an interactive group where all the participants are free to talk to other members and discuss some points. This article is a research on how teenagers are using digital
media devices. The researchers were conducting focus groups with 80 middle- and high-school
teenagers (there were provided 2 geographical regions for interesting
regional comparisons - the eastern and western USA) [1]. The main purpose of this study is to get to know what adolescents are thinking about different kinds of digital devices - such as mobile
phones, video game systems, the internet etc. and to realize which the
functions they play in the daily life. There have been developed four main themes from 11 focus group interviews: "(1) an
awareness of digital devices; (2) a sense of temporal displacement; (3) social
functions; and (4) a palpable sense of risk associated with using them" [1].
According to the researchers and my surprise the use of focus
groups was decided to be appropriate for the ages of the participants. But in my opinion the limitations of this method is much deeper than advantages - because in focus group participants are supposed to discuss together and express opinions. But in this age people are shy and not ready to show their real attitude to some issues, or they just wanna brag in front of mates. Also the issue with strong opinion leader who could convince everyone in his point of view could affect the results.The findings are not broad and general but thay are more focused
and specific. But I think, despite these small limitations, this approach
is one of the best for such kind of study. But what I suggest the researchers for the
future study is to complement the paper with quantitative methods in order to
get more objective results.
Concerning the paper “Comics, Robots, Fashion
and Programming: outlining the concept of actDresses” by Fernaeus, Y. &
Jacobsson, M., I found it quite interesting, but for me
some points were pretty much difficult to grasp (only when I reached the part
with examples I really understood everything). The researchers are making a
short overview of approaches to physical programming and focusing on the concept
of actDresses (that was inspired by comic sign system and practices of clothing
and accessorising) and supporting it by three example scenarios of how the concept
can be used for controlling, programming, and predicting the behavior of
robotic systems (e.g. using physical clothing, labels, and accessories for
controlling physically embodied systems). My favorite scenario is the first one
which is designed for the Pleo robot dinosaur.
Seminar question: In your opinion, is mixed
research better than using separately qualitative and quantitative?

Reflections "after" / Theme 3
I must say that I have already had experience
in working with both quantitative
(and SPSS-program in particular)
and qualitative methods.
Concerning quantitative methods, last year I was taking part in a mutual research
“Public discussion and agenda-formation in Russia” of The Berkman Center for
Internet & Society at Harvard University and National Research Institute - Higher
School of Economics, Russia. And what about qualitative method, I usually work
with it when I’m writing my course-papers. But I must confess I have never deeply
thought about advantages and disadvantages of this method and probability to
combine qualitative and quantitative methods.
That’s why I find this week very fruitful – it gave
me a lot of reflections on both methods and I got to know about a totally new
and very promising method - mixed research. During the lecture our main focus was on
applying different kind of methods to online-learning - we have looked through different
types of behavior in online-environment: social presence, teaching presence,
cognitive presence. It turned out that gender makes no difference at all in the
amount of activities. The lecturer told us that they used the approach of
autoethnography that is creating research focus, documenting personal
reflection data, self-observation data, personal memory data and comparing to
external data. Now we are able to describe 5 characteristics of quantitative
methods, explain rationale for choosing quantitative methods, outline the
challenges of quantitative method. Also during the lecture we tried to answer
the questions what are the necessary and sufficient conditions of knowledge,
what are its sources, what is its structure and what are its limits.
Unfortunately our SPSS-lab wasn’t very successful,
because there was some kind of error in program, but I managed to practice at
home. First of all, I defined a data set which contained several questions
about the different platforms-usage for listening to radio. Hence, I conducted
an overview analysis of the variables in the dataset.
Then I run frequences and percentages in SPSS,
by choosing a selection of variables and copied the tables from SPSS to Excel
where I formed a bar-chart. The bar was presenting the total amount of people
answering (100%) the people using it (90%) and the ones, who don't use pod
radio (10%), displayed either wise in numbers or percentages. The final task
was about crosstabs in the SPSS program – that are Suitable for occasional
analysis of two or three variables; here I decided to choose web radio and pod
radio as the variables – and it gave me the perfect overview of two variables
at the same time.

Reflections "before" / Theme 3
To be honest I was fascinated by both
articles “Mixed research and online learning: Strategies for improvement” by Lowenthal,
P. R. & Leech, N. (2009) and “Emotional presence, learning and the online
learning environment” by Cleveland-Innes, M. & Campbell P. They are both
concerning very current and up-to-date topic – online education. And as far as
this sort of education is growing (and I often use it) we definitely need to
increase the quality of it and understand better all the problems and details concerning it.
The main problem of the first paper “Mixed
research and online learning: Strategies for improvement” by Lowenthal, P. R.
& Leech, N. (2009) is a very low
quality of research on e-learning. The researchers are comparing
online-learning and traditional way of learning. In this particular chapter the
researchers are inventing a new method to collect data, that they name mixed research.
Mixed research is a new strategy of researching that unites quantitative and
qualitative analysis to achieve a more trustworthy way to do a research. In my
opinion, the purpose of study more exploratory because the researches are
creating a new method to grow the quality and trustworthiness of online research
studies. According to Lowenthal, P. R. & Leech, N. qualitative data have to be
checked with a comparative analysis: content analysis,
the number of words,
social presence, keywords,
domain analysis, taxonomic analysis and component analysis. The researchers are claiming that if we are relying on the only one kind of analysis, there could some interpretative (hermeneutics) errors happen. They
come to conclusion that using both quantitative and qualitative methods of data analysis will help solve some kinds of
problems that one method or even several methods approaches will not [1]. But I must say that researchers
totally understand that such kind of research is definitely much more
complicated than simply quantitative
and/or qualitative studies separately. But this new way of researching in turn
will definitely increase both quality of online-learning research and all that we
know about e-learning. I think that this method is a good way to combine the
best parts of qualitative and quantitative analysis. But I think the paper is
lacking some more information, data and, actually, critique against this
method, because it can’t be so that this method is the best one in the world.
The main problem of the second paper
“Emotional presence, learning and the online learning environment” by Cleveland-Innes,
M. & Campbell P. is the question of the presence of emotion in online learning. The researchers
are wondering if emotion influence the experience of online learning (as far
as online learning is using new technologies). The purpose of the study is
explanatory. They are using mostly quantitative methods – their data is
collected from surveys, conferences, discussion transcripts and is presented in
the following “Findings” part of the paper. But they also have qualitative data
from the open questions in the survey. They come to conclusion that emotion may
constrain learning as a distracter, but on the other hand, it may perform as an enabler in support
for such activities as thinking, decision‑making, stimulation and directing [2]. And they conclude that emotions are definitely present
in e-learning communities. The researchers define emotional presence as an experience
which is overhang in the online environment. They also have many
questions and aims for the further research (such as, e.g. 'how do emotions impact design
and organization, facilitation and direct instruction' [2]?) I find this as a really good example of
how qualitative methods can be used in research to obtain a very good result.

Reflections "after"/ Theme 2
During this week I have learned both practical and theoretical things that I definitely going to use in my academic researches.
First of all, I found both articles by Gregor and Sutton & Staw very useful. After reading and fruitful discussion on the seminar I have a firm definition of what is theory. We tried to find answers (and I believe we succeed :) to the following questions: What is theory? Of what is theory constructed? How could theory be expressed? How could knowledge be applied? Should the knowledge be relevant and useful in a reasonable sense? Are there some political for example or social issues that are associated with the use of the disciplinary knowledge? Now I know that theory describes, explains, enhances understanding of the world and provides predictions of what will happen in the future and to give a basis for intervention and action. Theory is explanation of why and how acts, events, structure, and thoughts occur. Theory is definitely not data, references, variables, diagrams and hypothesis, but the theory can be supported and built on them. Also we got to know 5 different types of theories (analysis, explanation, prediction, explanation and prediction, design and action), their distinguishing attributes, structural components of theory and their definitions [1].
Second of all, I found very interesting the discussion about different kind of theories during the seminar. It was interesting to develop and sort out in “Game Theory”. With my group-mates we examined the definition and applicability of this theory. We made out that Game Theory provide both explanation (with a set of mathematical tools) and prediction of possible actions of individuals participating in some sort of game. It is a theory that has its roots in EP-theory - explanation-and-prediction-theory. EP-Theory in general does not however have its aim at explaining behavior by applying math methods, but it uses psychology. Also we had a very interesting discussion about applying this theory to practice (including the discussion of the movie “21”).
Thank to our seminar group I also know more about digital politics theory that is using the internet is a positive predictor for all forms of political participation for young people, and media richness theory that is used to rank and evaluate the richness of certain communication mediums, such as phone calls, video conferencing and e-mail.

Reflections "before" / Theme 2
In very general words, theory could be explained as
providing explanations, predictions and being testable. Theory has nothing to do with a subjective
opinion of a researcher. Theories are always abstract and general, and they aim
to describe, explain, predict what is going to happen in the future, reveal the
relation between cause and events and give a basis for intervention and action.
Theory is the answer to the rows of WHY. Theory is
about the connections between phenomena, a story about WHY acts, events,
structure, and thoughts happen. References, data, variables, diagrams and hypothesis are not theory itself.
They could support the theory and be some kind of evidence.
I chose the research paper “A game of win–win or win–lose?Revisiting the internet’s influence on sociability and use of traditional media”
from the research journal “New Media & Society” (IF=1.394)
The article examines the influence of internet adoption
and internet usage on sociability and use of traditional media. It’s difficult
to allocate their theory to one class. In my opinion their theory is primary analytic
and explanatory but with the elements of perspective statements. They discuss and consider the impacts of the internet on sociability and use of traditional media, and
monitor closely the connections and relationships between sociability and traditional media, which is in their turn will head them to the determination of a false connections between the sociability, use of traditional media and the internet.
As far as their theory on one the hand is analytic they
use words, diagrams and tables to represent their research. They describe what
they understand under the definition of traditional media and what had happened
in the past when one traditional means of media replaced another. On the other
hand, their theory in explanatory (according to Gregory we could label it as a
theory for understanding, type II), because they are figuring out what is the
connections (and kind or connection it is) between internet’s using and sociability and spending time on traditional
media. They use primary constructs, statement of relationship, scope and causal
explanations. The data of this study come from a series of annual telephone
surveys that were primarily conducted in Hong Kong at the end of 2003, 2004 and 2005. They use such
measurement as Internet adoption status, Sophistication of internet usage, Diversity
of Online Method, Adoption history and Control variables.
I think that authors are using these theories in an
excellent way because their main questions are HOW and WHY this phenomena occur
– and the explanatory theory fits them perfectly. But definitely there are some
limitations of it, e.g. the first limitation of the study is that now we can't clearly figure the a product of the
scopes between the internet, traditional media, and sociability because there technologies is rapidly changing in the contemporary world. The second limitation is the way of causation was hypothesized.
It is could be fair to argue that if the person is an introvert, he will be use internet to socialize more than to enlighten and entertain (as extroverts for example). The third limitation is about the method that was used to evaluate the interaction influence of adoption history.
