Challenges faced by Adult L2s
in SLA
• Intrinsic and Extrinsic Motivation Factors
• Chinese as surmountable challenge:
Recent corpus research reports 53,623
words, of which there are 10,632
polysemous words
• The need for a structured and incremental
approach to introducing, acquiring and
applying vocabulary in a communicative
setting
Non-Drill Approaches
To Ensure Retention
To Address Challenges Learners Face While Acquiring,
Reviewing and Applying Vocabulary, this Presentation Seeks
to:
Introduce Motivational Dimensions in Adult L2’s SLA
Process,
Introduce Currently Ongoing Research Based on Respected
Corpora,
Discuss Practical Applications Derived From These Results,
Introduce A Curriculum Design That Enables A Natural
Progression Through FLO Topics,
Discuss How This Combination Enhances Learners’
Metacognitive Skills As Well As Automaticity, and
Conclude by Discussing How the Above Methods Address
Adult L2’s Motivational Dimensions.
Challenge One: Intrinsic Motivation
From Appraisal to Motivation
• Scherer’s Five Dimensions of Appraisal:
– Novelty
– Pleasantness
– Goal relevance
– Coping potential
– Self and social image/ compatibility
A Tripartite System
for Stimulus Appraisal
• Amygdala
• Orbitofrontal Cortex
• Body Proper
Sensory
Association
Cortex
Orbitofrontal Cortex (Makes
decisions based on stimuli’s value
assessments)
Sensory Cortex
Amygdala
(processes sensory
inputs)
(“Hey, we hate that / love that”)
Hypothalamus (Hormonal control of
Thalamus (sorts
physical responses to emotions)
and routes input)
Brain Stem
* Reticular formation carries consciousness
* Medulla oblongata controls basic body functions
Stimulus
* Pons relays movement info between cortex and cerebellum
(visual, tactile,
auditory and
gustatory)
* Midbrain coordinates sensory and motor functions
Endocrine System (Internal regulation
– controls body functions by secreting
hormones and peptides)
Motor System
(External regulation
-- body movements)
Autonomic
Nervous System
Sympathetic NS (Reactive –
Parasympathetic NS (Rest,
agitation response, fight or flight)
digestion and growth)
Challenge Two:
Massive Burden of Vocabulary
• By extrapolating patterns and structures
out of the natural language, corpora
research helps ensure goal relevance by
shedding light on more natural approaches
to curriculum design and classroom
practices.
• Corpora research help learners cope with
the enormous bank of Chinese vocabulary
by suggesting better learning strategies.

Comprehension
We sure can’t ask learners to
“just go through the dictionary”...
Meaning of a Chinese character…
Should not be viewed as a pinpoint, but as a
sphere of possibilities that changes with
context and evolves with time.

Question: How Then Do We
Prioritize Vocabulary for
Structured Learner Retention?
Solution: Corpora Research
Corpora Consulted in this
Research Project
•现代汉语研究语料库
•清华大学ZW大型通用汉语语料库
•現代漢語平衡語料庫
• Lancaster Corpus of Mandarin
Chinese
According to Latest Data from the 现代汉语研究语料库,
Each POS Occupies the Following Percent
in the Chinese Language
POS Frequency of Occurrence and
Percentage Represented
Derived From 清华大学ZW大型通用汉语语料库
When the following formula is
used…
占总词条比率
Percentage Represented
----------------------------------- = “per-word payoff”
出现频率
(i.e. Effectiveness Ratio)
Frequency of Occurrence
The Following Analyses Become Possible:
We find that:
• Pronouns’ Effectiveness Ratio (per-word
payoff)
= 6.21% / 1.66% = 3.74
• Nouns’ Effectiveness Ratio (per-word
payoff)
= 31.42 / 48.76 = 0.64
• By Comparison: A regimen that assigns
priority early on to pronouns will be 6.13
times more efficient than a regimen
favoring nouns
Research Results Show that:
When Designing Curriculum, Teaching or Learning,
Vocabulary Should be Prioritized by POS

Challenge Three: Structured and
Incremental Approach is Needed to…
• Navigate through the FLO topics in natural
progression,
• Pace the introduction of vocabulary in a
manageable and digestible fashion, and
• Develop a thorough understanding of
natural phenomena in the Chinese
language.
Research Finding:
Natural Progression Through FLO Topics (1)
Research Finding:
Natural Progression Through FLO Topics (2)
Select Keywords By FLO Topics
• Example -- Military:军事、军队、国
防、空军、海军、征兵、服役、转业、
民兵、预备役、军衔、复员、文职、
后勤、装备、战备、作战、训练、防
空、军需、武器、弹药、退伍…

When Vocabulary Requirement
Considerations Take into Account…
• Frequency of use
• Percentage representation in
overall language, as well as
• FLO Topics
•More and potentially better paths
to the goal become discernable,
and
•The resultant vocabulary pool is
far more manageable to students,
increasing students’ coping
potential.

Sample Passage (1)
UNDP報告中所謂中國對周邊國家的“威脅”,無
非是兩個方面:第一,中國的勞動力成本低廉;
第二,中國與這些國家出口產品基本同質。其實
歸結為一點,那就是相對於發達國家,中國與周
邊國家具有相同的優勢,因此,產業間和產業內
的相互競爭不可避免。在聯合國發展項目委員會
看來,這純粹是一個零和博弈:中國得即周邊國
家失。造成目前這種局面的原因僅僅在於中國先
行一步,周邊國家“未能趕上中國的步伐”。
Sample Passage (2)
UNDP 报告 中 所谓 中国 对 周边 国家 的 “ 威胁
”, 无非 是 两 个 方面 : 第一 , 中国 的 劳
动力 成本 低廉 ; 第 二 , 中国 与 这些 国家
出口 产品 基本 同质 。 其实 归结 为 一点 , 那
就 是 相对 于 发达国家 , 中国 与 周边 国家 具
有 相同 的 优势 , 因此 , 产业 间 和 产业 内
的 相互 竞争 不 可 避免 。 在 联合国 发展 项目
委员会 看来 , 这 纯粹 是 一 个 零和 博弈 :
中国 得 即 周边 国家 失 。 造成 目前 这 种 局
面 的 原因 仅仅 在于 中国 先行 一 步 , 周边
国家 “ 未能 赶 上 中国 的 步伐 ”。

• Mean Frequency Percentile
Showed That: Words required for
this task is within top 2.51% most
common in the language,
learners' production proficiencies
will benefit from these choices.
Corpora Basis for Choice of
Production Operators (3)
• “Per Unit Categorical Effectiveness of
Task with These POS” Showed That:
POS of these words are very common
(averages to be within top 2.51%
most commonly seen), highly
adaptable in substitution and
expansion exercises.
Corpora Basis for Choice of
Production Operators (4)
• “Mean Unit (3) Categorical
Frequency for These POS Pairing
Sequences” Showed That: These
POS pairing sequences often
appear, meaning learners are
likely to find this pairing to be
helpful in production tasks.

Opposed to the “Fire Hose” Approach?
