PHENOMENOGRAPHY
Research method adapted for mapping the
qualitatively different ways in which people
experience, conceptualise, perceive, and
understand various aspects of, and phenomena
in, the world around them
(Marton, 1986, p. 31)
• aims to:
reveal categories of description
delineated by dimensions of variation
emerging from data & hence,
structuring categories into outcome space
CRICOS Provider Code: 00113B
WHY PHENOMENOGRAPHY?
• demonstrated efficacy in a range of educational
research including mathematics.
• focus on ideas expressed by the group of participants.
–attempts to describe phenomenon as seen by participants.
• variation in conceptions is expected.
• identify variation (categories of description).
–diversity of students → range of variation
–structure categories into an outcome space
CRICOS Provider Code: 00113B
OUTCOME SPACE
• structured set of categories of description
• one category likely to display “correct meaning,
correct knowledge or correct understanding” (Webb,
1996)
–as accepted by community of practice
• other categories display less complete understanding
• individual may hold >1 conception.
• outcome space considered to be final result of
phenomenographic investigation (Marton,1988).
CRICOS Provider Code: 00113B
ANALYSIS
• each data source considered several times
• categories of description
–groupings of meaning statements
• dimensions of variation
–themes of expanding awareness
• emerged from data over many iterations
• categories delineated in terms of dimensions

OVERVIEW OF
PHENOMENOGRAPHIC STUDY
CRICOS Provider Code: 00113B
THIS PHENOMENOGRAPHIC
STUDY
•Investigating conceptions of rate
• Selection of sample:
– aim for maximum variation;
– 20 diverse Year 10 students.
• Conduct interviews:
– phenomenographic video-recorded semi-structured interviews
– based on computer simulations, enabling exploration of constant & variable rate
in multiple representations
• Phenomenographic analysis of responses to reveal students’
conceptions

Consistent
presentation to
ensure attention
to same
phenomenon
PHENOMENOGRAPHIC
ANALYSIS OF THIS STUDY
• immersion in data.
–each video repeatedly viewed.
–gestures used to give insights into meaning of words
• pooling & grouping of meaningful responses from
data into meaning statements.
• grouping of meaning statements into initial
categories.
• formation of initial dimensions
• final dimensions & categories developed over
many iterations.
• categories structured into outcome space.
– based on dimensions
– probably hierarchical.
–some categories more complex & complete.
CRICOS Provider Code: 00113B
EVOLUTION OF
CATEGORIES & DIMENSIONS
• interviews transcribed
–checked against audio & video
• immersion
in data
• interpret gist of participants’ verbal & non-verbal
communications
• set of meaning statements

Transcript
it goes up three point two meters
every half a meter
Interpretation
• suggests understanding of rate involving constant change in one
variable wrt unit change of another variable.

R: what do you think the graph [of non-rectangle window] might look like? [long
pause]
S: I don’t think it would be a straight line [pause] because this window’s not
square hmm I dunno because its up the top umm curved there [pause] umm a
straight line means its always the same
R: what’s always the same?
S: the umm
Interpretation of Gestures
• identified key differences in rate for the window
• gestures communicate awareness that graph of
curved section not the same rectangular section.
• constant rate results in linear graph

Type of Rate: with attributes ‘constant’ & ‘variable’

ITERATIVE PROCESS
• consideration of structure of outcome space
–least to most complex
• some categories more complex & complete than
others
–include aspects of awareness of earlier categories
• more detail in descriptions of categories
–return to data
–focus on how rate was experienced with less emphasis
on what the participants did or said
–ask “Can these be grouped?” “Are there examples of
things that students say/do which illustrate this
category?”

VERSION 5
• Dimensions of Variation
• another 2 dimensions added
– Property attributed to rate: with attributes ‘quality’ & ‘quantity’
– Characteristics of property: with attributes ‘1-fixed’, ‘1-changing’, ‘2changing’
• labels & attributes of other dimensions changed
– Context became Related variables: with attributes ‘distance&time’ &
‘any pair’
– Type of rate & Relationship were combined in ‘nature of
relationship’ with attributes with attributes ‘qualitative’, ‘quantitativeconstant’& ‘quantitative-variable’
