Unit 1: Role of Research in Knowledge Construction and Discipline Development
Pop Quiz Question
Which one of the following is an example of “shifting paradigm of a
discipline”?
 a.
Whereas Piaget believed children’s limited language ability
during early childhood shows they are ego-centric, Vygotsky believed it
shows children are gradually internalizing language to guide their
thinking.
 b.
Chomsky’s research convinced researchers that the
reinforcement theory based on behaviorism was not adequate to
explain children’s language development. Chomsky’s scholarly work
intrigued the cognitive revolution in psychology and linguistics.
 c.
Dr. Lan found from his studies that introducing self-monitoring
in the learning process improves student learning outcome so he
developed a protocol that helps students systematically evaluate their
understanding in his statistics class.
 d.
Cumulating teaching experience year after year, senior teachers
tend to know what works and what does not work in classrooms.

Practitioners
 Describe phenomena of interest
 Predict or explain phenomena of interest
 Control behaviors (promote desirable and reduce or
eliminate undesirable behaviors)

research in that
a. causal-comparative research is interested in statistical
relationships between variables and experimental research
is not.
b. experimental research relies on data collection from

1. X precedes Y in time.
2. X and Y are related.
3. No other variable is related to Y.

Unit 4: Identifying Research Topics Based on Literature Reviews
Why Are Research Topics Important?
 Selecting and defining a research topic is the first
step in applying the scientific method
 The research topic provides focus and structure.
 The research topic is the driving force of a research
project, which determines other aspects of the
research study (e.g., sampling, assessment, analysis,
etc.)
Unit 4: Identifying Research Topics Based on Literature Reviews
Characteristics of Good Research Topic
1.
2.
3.
4.
5.
6.
The topic is theoretically based.
The topic has theoretical or practical importance.
The topic is researchable.
The topic is interesting.
The topic is ethical.

skills, resources, and time available.
Unit 4: Identifying Research Topics
Sources of Research Topics
 Theories
 Studies that can be replicated with issues to be
clarified (e.g., population, assessment, analysis,
etc.)

interest, relations among those variables, and aspects
of the sample.


e.g., “The purpose of the study is to investigate the
psychometric properties of a new measure of spatial ability
for middle school children.”
e.g., “The topic to be investigated in this study is parents’
beliefs about homework for primary grade children.”
Unit 4: Identifying Research Topics
2-37
Research Topics Stated as Purpose Statements
 Qualitative research topics are often stated in more
general language at the outset of a study because the
focus of the study will likely emerge after time in the
field.
 e.g., “The purpose of this study is to describe the
experiences of elementary students who have
previously been retained.”
 e.g., “This qualitative study explores the feelings of
new teachers in large urban districts.”

gained through literature review.
 Hypotheses in quantitative studies are formulated
before conducting the study.
Unit 4: Identifying Research Topics
54
2-54
Hypothesis Testing For Quantitative Research
• The hypothesis is used to guide the research study.
• The researcher conducts the study and then analyzes
the data to determine if the hypothesis is supported.
• Hypotheses are not proven—they are supported or
not supported.
• Valuable contributions to the literature can still be
made if a hypothesis is not supported.
• Hypothesis testing contributes by expanding,
refining, and revising the literature base.
Unit 4: Identifying Research Topics
2-55
Hypothesis Testing for Qualitative Research
 Qualitative studies
 The qualitative researcher does not state formal
hypotheses before conducting studies.
 Qualitative researchers may develop guiding
hypotheses for the proposed research.
 Qualitative researchers often generate new
hypotheses during the course of their study.
 Qualitative researchers may generate research
questions from their guiding hypotheses.

Examining Association Hypotheses
 “In this correlation study, the relationships between
Chinese international students’ acculturation, ethnic
identity, English proficiency and their attitude
toward seeking professional counseling service were
examined. The variables of acculturation, ethnic
identity, and English proficiency were used as
predictors to predict the criterion variable of attitude
toward seeking professional counseling service.”

Descriptive Statistics vs. Inferential Statistics
 Descriptive statistics: Statistical procedures that help
describe the information gathered during a research
study
 Inferential statistics: Statistical procedures that
determine ho likely it is that results obtained from a
sample or samples are the same results that would
have been obtained from the entire population.

jail increased the aggressiveness of behavior after being released.
The researcher made
a.
a correct interpretation of his research finding because there is
a strong relationship.

a wrong interpretation of his research finding because
aggressiveness of the behavior was the cause for lengthy
sentence in prison.
c.

 For the following abstract, what do you want to
add if space permits?
 “Two hundred second-grade students were
administered a battery of published cognitive tests
that measured a variety of academic achievement
variables. The students were drawn from three
elementary schools in a large, urban school district.
All were tested near the end of second grade. Test
administrators administered the tests in three
sessions because students might become fatigued by
taking the entire battery in a single testing session.
The three hypotheses were confirmed. Implications
for cognitive and development and directions for
future research are discussed.”
