Qualitative Research – Week 7 – Qualitative Research Critique

Last week I saw Janet Vertesi speak about her research “Seeing Like Rover” and found it so interesting that I decided to use it for the assignment this week – a Critique of a Qualitative Research Paper:


 

EDUC 200B – Qualitative Research Critique
“Seeing like a Rover: Visualization, embodiment, and interaction on the Mars Exploration Rover Mission”, Janet Vertesi, 2012 Society of Fellows, Princeton University, Princeton, NJ, USA

The study’s purpose is to investigate how physical representations of objects (embodiment), plays a role in a team’s social order and organization. New members for example, need time to be able to connect affectively to a remotely operated thing to finally “see like a rover”. This skill connects the team members socially and physically to the Rover. “Jude, too, explained to me that when something is not right with the Rover, ‘We feel it in our bodies.” (Vertesi, J., 2012, pg. 11). It makes them talk in the first person plural pronoun, “we”, to talk about the Rover. “We expect to turn around and take images of [the target] … . We’re about four meters from the outcrop…” (Vertesi, J., 2012, pg. 13)

Her laboratory ethnography consisted of more than 80 interviews, 360 meetings, and 10 different locations over a period of 2 years. The NASA Mars Exploration Rover team consists of several hundred scientists scattered all over the world who have daily meetings to decide what the Rovers’ next actions are going to be. The use of the body to simulate or explain moves the Rover’s “eyes”, “arm”, and “fingers” should do was observed during these meetings but more frequently while working alone through a problem or planning a task.

Her conclusions were that embodiment connects every team member into the body of the Rover, enunciating a sense of one. A shared responsibility, complicity and solidarity towards one mission and a common goal. She also argues that visualization of data and it’s subsequent interpretation and understanding, along with the visual nature of embodiment, serves as an instrument of social and organizational order. “Each [scientist] interacts with an image in a way appropriate to his or her position, consistent with both disciplinary heritage and with the organizational protocols of their laboratory, shop floor, or teleconference line.”, (Vertesi, J., 2012, pg. 17).

Even though her conclusions and findings were interesting, I felt that the research purpose was unclear as far as what practical applications, consequences, or impact it could have. The abstract itself states that this study looks further into understanding the “importance of embodiment to visualization” and how it plays a role in “maintenance of social order within the organizational context of the laboratory”, “contributing to our understanding of representation in scientific practice.” What are some practical recommendations or activities that other scientific teams could do to improve team-work, social orders, and/or communication?

I was baffled at how much data she must have collected with the many interviews, meetings and site visits. She did not mention how she specifically collected her data during the interviews yet her precise descriptions of body movements, objective and impartial description of observations show that her methods were effective. “She then raises both hands to either side of her head, forearms perpendicular to the floor, head tilted slightly down, fists open but fingers lightly curled.” (Vertesi, J., 2012, pg. 2). Along with these descriptions, came a few figures showing the positions described, enhancing our visualization.

I applied the “Criteria for a Good Ethnography” (Spindler & Spindler, 1987, pg 18-21)  to this piece and the top 3 criteria that were best met:

  1. “Criterion II. Hypothesis emerge in situ.” The unique organizational arrangement of this team of scientists contributed towards the construction of her hypothesis. She states; “I seek to broaden our understanding of visualization and embodiment from individual perception or dyadic interactions to include the collective work…” Through her observations she was then able to focus this general statement into a more specific hypothesis that embodiment contributes to the social order of the group.
  2. “Criterion III. Observation is prolonged and repetitive.” I feel that the amount of data she must have collected is enormous. Not only she interviewed more than 80 people in 2 years – almost a person per week – she participated in over 360 meetings – one every two days. She does not mention that se was a participant observer. I actually attended a class where she presented this study and she mentioned that she had a job or function there. That is how she was able to have participated in that many activities – she went there every day.
  3. “Criterion IV. The native view of reality is attended…” The very subject of her observation is how the native, in this case the scientists, expressed themselves through physical gestures when talking about the Rover. She was exposing to us how they viewed their world at the same time as how the Rover saw Mars. One other point that stood out for me in this study was how well she used previous research and articles throughout her introduction and conclusion. It showed me how deeply one can analyze a niche behavior and extract relevant generalizations about human behavior and group dynamics. My initial negative reaction towards the research’s purpose transformed into a sense of awe at the extrapolation capabilities we can attain when closely and attentively observing phenomena.

 

Tech 4 Learners – Week 7 – Prototype Presentation

Prototype presentation: 

Text for presentation: 

Learning goal: 

We want ‘A’ to learn the value of communicating with others.

Theory of learning:

Our tool intends to offer him practice in generating new words and then rewarding him with the playback experience. This will reinforce that his words have meaning, power and entertainment value. If he is interested in the material presented, he will engage in narrating it. Ideally we want him to transfer these skills into real life situations.

If the program:

  • Utilizes engaging content for ‘A’
  • Replays ‘A’s words so he and others see their value (and enjoy them!)
  • Initially offers prompts for ‘A’ to speak then gradually reduces them

Then ‘A’ will overtime…

  • Generate spontaneous and increasingly complex sentences.
  • Transfer those skills to real life situations.

Question:

  • How do we build on what we’ve learned to create a tool that encourages ‘A’ to express his thoughts with less prompting?
  • What additional mechanism or feature could support ‘A’ in transferring these skills to real-world situations?
  • Did some videos but there would be no time to present it – we had 60 seconds!

Videos

I prepared a stop-motion video for presenting the prototype as well:

Which is the final result of some thinking and prototyping:

LDT Seminar – Week 7 – Expert Interview

I interviewed Candice Thille, Ann Porteous, Sara Rutheford-Quach, and Karin Forssell regarding my learning problem. The greatest take-away for me was the vast amount of research and practice that has already happened. The depth and width of the problem space is enormous yet it helped me immensely in understanding the need to become more specific and focus on areas that interest me the most and with which I have the most familiarity with.

Learners’ goals: From the learner’s perspective, I understood from the interviews that there is a real challenge in knowing how to effectively create, publish, run and/or lead an online course. Very few tools aid the content-expert in acquiring PK and PCK  during the process of publishing a course for example. There are few lesson planning tools embedded in the existing educational technologies out there.

Context: I was ‘forced’ to learned about all the distinct online course types and methodologies that exist in the market to be able to ‘talk-the-talk’ during the interviews. This showed how rich the field is and how much there is to advance in it still. A major take-away was that human interaction has to be designed into a course, be it teacher-student or student-student along with a temporal dimension so that the course is effective in terms of course completion and depth of learning.

Special Needs: The learner’s needs are very specific to the subject matter I found out through the interviews. A statistics course has different needs than a linguistic course and different needs than a programing course. The scaffolding required for each subject matter would be different. The teaching strategies are different. The activities recommended to be done with the learners will be different.

In conclusion, the interviews were a tremendous source of information and served a great purpose of directing further inquiry, research and the desire to repeat the interviews in order to evolve the debate once I can get a better grasp of the material. Inspiring.

Learning Environments – Week 7 – Class Notes

The Reading Czars this week outdid themselves 🙂 The group was divided into two. My group met in the classroom.

Lego Run:

legos_render

We were divided into 2 competing groups. Each group was given a set of Lego pieces – the same required to build a model. This model can only be seen by the Observer, who describes to the Runner  what it looks like. The Runner then tells the Builder about the model, who tries to build it as precisely as possible. In the middle of the exercise, an extra Runner was added, which sped up the process immensely. Less waiting time for the Builder. More bite sized instructions.

Model -> Observer -> Runner -> Builder -> Replica

Learning Environments – Week 7 – Reading Assignment

“Within these multiple overlapping zones, students navigate by different routes and at different rates. But the push is toward upper, ratherthan lower, levels of competence.” (Brown, 1994)

For me this is a key take-away from this piece since it sums up the power of well lead group activities or discussions and seems to potentialize ZPD. Not only there is a common ZPD for the group, but individual ZPDs can be attended to by not one but several people at once.

The shared responsibility of the learning goal for the group also tends to be higher than that it would be for an individual. Not only can people feed of each other’s knowledge but their own shortfalls will be covered by others. The feeling of community and being part of a team also helps to upward spiral this synergic effect.

The meaning of the group can also be more encompassing by including the learners home environment, culture and funds of knowledge. If these factors are also seen as multiple overlapping ZPDs, the outcomes of learning are probably exacerbated and reach the student’s extended learning community.
