Theoretical framework理论框架
“[(habitus) (capital)] + field = practice” (Bourdieu,1989, p.101)
“[(惯习)(资本)]+场域=社会实践”(布迪厄,1989, p.101)
People make language choices as a form of their social practice according to
the positions (capital) and dispositions (habitus) they have within a given field
(Bourdieu, 1991). Language choices may generate products that respond to the
demands of a given field (Bourdieu, 1991).

 “statistics are bound to be abstract” and with the complement of
interviews and texts, profound phenomenon can be revealed “even more
clearly” (Bourdieu, 1996, p. 174)

Research question and null hypotheses:
研究问题和虚无假说
RQ1. Is CHL proficiency of young Chinese Australian adults in urban
Australia positively influenced by their investment of capital, the
strength of their habitus of “Chineseness”, or both?
H01. The habitus of “Chineseness” of young Chinese Australian adults
in urban Australia has no statistically significant positive impact on
their CHL proficiency.
H02. The investment of capital of young Chinese Australian adults in
urban Australia has no statistically significant positive impact on their
CHL proficiency.

Why Structural Equation Modeling?为何选择结构方程模型?
• SEM is theory driven. 理论驱动
• SEM has the capability to assess reliability and validity.性效度检验
• SEM improves statistical estimation by accounting for unique
disturbances in the estimation process.减少测量误差
Statistical assumptions:
• Interval level of measurement
• Multivariate normal distribution
Chineseness = v9 × .18 + v7 × .21 + v4 × .21 + v3 × .16 + v2 × .23

17-33 (Levinson, 1978)
• Why before 13?为何选择13岁?

Sample size:样本量
•
•
•
•
•
Different statistical models have different rules-of-thumb to identity the optimal
sample size.
There is a mathematical relationship amongst sample size, effect size, significance
level, and power value.
e.g. in regression,
 N ≥ L / f2, where f2 = R2 / (1 - R2) and L = 6.4 + 1. 65 × k - .05 × k2 (Green, 1991)
 significance level .05 / power value .80 (Cohen, 1992)
 effect size .02, .15, .35 (Cohen, 1988)
 G-Power software
SEM in general requires a larger sample size.
Unfortunately, there is a lack of agreement on the exact meaning of “a larger sample
size”.
It is recommended that the sample size be no less than 200 in order to provide reliable
results (Bentler & Chou, 1987).

Why snowball sampling?为何采用滚雪球取样法?
• Possibility sampling (e.g. simple random sampling,
systematic random sampling, stratified sampling, or cluster
sampling) is practically impossible for the current research.
• Snowball sampling is commonly done when the participants
are rare and thus difficult to access or identify (Nardi,
2006), for example, in heritage research (Gibbs & Hines,
1992; Hall, 1992; Kiang, 2008; Pao, Wong, & TeubenRowe, 1997; Root, 1992).

Fields
Languages always produce the products that respond to the demands of a
given field (Bourdieu, 1991).
• What are the products produced by Chinese Heritage Language learning?
• Does Chinese Heritage Language practice produce any valued asset?
• Are these assets ‘capital’ or ‘habitus’?

Methodological thinking behind interviewing:
• Power relations (Bourdieu, 1999)
权利关系 (布迪厄,1999)
• Researcher’s subjectivity: Why I am entitled to conduct this interview?
研究者的主体性:为什么我可以做这个访谈?
• Benefits: Reliability and validity
改善性效度
The interviewees seemed to consider this situation as an exceptional
opportunity to “make themselves heard” and to “carry their experience over
from the private to the public sphere” (Bourdieu, 1999, p.615). Their speech
seemed to convey “a joy of expression” (Bourdieu, 1999, p.615).

Power relations (Bourdieu, 1999)
 Asymmetry of symbolic power and unequal distribution of capital,
“cultural capital in particular” (p. 609)
 “Active and methodical listening” (p. 609)
 Verbal “signs of feedback” or “response tokens” (p. 610), such as
“yes”, “right”, “oh”, and “ok”, as well as aiding explanations in a
proposed rather than an imposed way, such as suggestions to offer
multiple and open-ended continuations to the participants’
hesitations or searchings for appropriate expressions (pp. 614-615)
 Non-verbal means, such as an open posture, approving nods,
appropriate facial expressions, and good eye contact

Why I am entitled to do this research?
 Two problematic extremes (Bourdieu, 1999)
 “Total divergence” (p. 612), where understanding and trust are
not possible
 “Total overlap” (p. 612), where nothing can be said and
questioned because everything goes without saying
 “Proximity and familiarity” between the researcher and the
researched (p. 610)
 Social difference between the researcher and the researched

Transcribing 转录过程
 Reliability: Member check and participant check
 Validity: Reconciliation of “fidelity” and “readability” (Bourdieu, 1999, p.622)
“The transition from the oral to the written, with the changes in medium, imposes infidelities
which are without doubt the condition of a true fidelity.” (Bourdieu, 1999, p.622)
