What authenticity means in learning? To whom? According to whom?

What? Learning by living experiences that are in nature

multidimensional (social, conceptual, perceptual…) (Dewey, Petraglia)

According to whom? (Science) teachers bring the “real” world into the school.

To whom? Students are engaged over time, they come to own the activity.

Outline

Background and proposed model

The serious game LOE

Empirical studies:

What attributes make the game LOE authentic?

Are students engaged into the game (in moments of interaction)?

Do students perceive the game as authentic? What cues enable them to make judgment of authenticity?

4

The Model


5

Authenticity and computer environment design

Immersion – make players feel they are « there » and « now »

Fidelity – realism of a simulation


6

Perceived authenticity

Trust (Human Computer Interaction), Presence (Psychology)…

Perception of unrealness in movies (Communication Theory, Brusselles & Bilandzik, 2008):

• This story is a fiction (fictionality)

• It is not like the actual world (external realism)

• It is incoherent (narrative realism)



Proposed model: authenticity in learning games

Appropriation of problems, ownership C.G.

The game


9

The game LOE: Laboratorium of Epidemiology


Learning objective: Critical Reading of Medical papers (based on statistics)

Learning approach: Learning by doing (make my own research and paper)

Students main tasks (170 students in 45 teams, 8 4h-sessions): Design and carry out an epidemiological survey, analyse a medical data base and present results to a congress

Game rules: Play the role of a physician (public health)

Authorization must be obtained in order to visit patients Papers assessed by congress scientific committee: Best papers

10

LOE: (simulated) web sites


11

LOE: simulated hospital and patients (video)

11

Hello

12

LOE: interactions with caracters of the game


13

Attributes of authenticity

• Mission – Mission content and resources – Original data

• Mise en scene – Graphical representation – Structure of the environment

• User freedom – Constraints – Level of control of the users

• Interactions – Characters’ personification – Behaviour and feedback from characters – Mode and media of communication


14

Empirical studies


15

Students’ engagement: method and results

Grid of analysis of moments of interaction The message includes: 1. Status of the speaker (student, physician) 2. Name and/or function of addressee 3. Goal of the interaction 4. Formallities 5. Context (teacher, commission)

Results (phone messages): 1+2+3+4 : 37% of 167 messages (15% to 50%). 24% teams never fulfill theses 4 criteria.


Hi, I’m Mike Smith and I want to come and visit 20 patients in your department

16

Student’s judgements: method

Phone interviews after each of 8 sessions with about 22 students (over 45 teams of 3 to 4 students each):

1. Looks real or not? 2. Useful or not?


Goal of analysis:

When do most students perceived the activity of the day as authentic, or not?

What cues enable them to make judgements of authenticity?

17

Student’s judgements: method and results


Perceived authenticity, three dimensions: • Internal incoherence: write a protocol, what for if data are given • Unrealistic: talk to an answering machine • Irrelevant: the patient cannot answer twice to the same question

(learn to control data, listen carefully) And interactions.

Cues (-> Match cues and attributes): • Figures are unquestionable: figures and variability make it real. • Characters (how they are represented, what they say, how they

behave): no high presence is required. • No graphical cues: low visual fidelity is enough.

18

Conclusions and future work

One model to design game and to analyse perceptions: Authenticity in game design, a compromise between

realism, coherence and relevance.

Two measures of perceived authenticity: - during the activity: students make the problems their owns, and

have appropriate behaviour /real life. - afterwards: interviews on usefulness and credibility.

Future work: What are the attributes that make a game authentic (for adults)?
