Bertrand Russell has defined mathematics as the science in which we never know what we are talking about or whether what we are saying is true. Mathematics has been shown to apply widely in many other scientific fields. Hence, most other scientists do not know that they are talking about or whether what they are saying is true.
- Joel Cohen, “On the nature of mathematical proofs”
There are no proofs in mathematics education.- Henry Pollak
Short, Sharp and Meaningful describing what the research is about. In qualitative research It may also be a ‘working title’ that the researcher will revise as his/her project develops.
Example of poor title An Investigation of a Survey and Analysis of the Influence of Program X on the Attitudes, Teaching Methodology, and Evaluative Techniques of Randomly Selected Male and Female Physical Education Teachers in Public High Schools in Kathmandu district
A qualitative inquiry into how 7th graders develop problem solving skills in mathematics at selected public schools in Morang district
Better title Influence of Program X on Physical Education teachers’ attitude, teaching methodology and evaluation techniques
(A qualitative inquiry into ) the development of problem solving skills in mathematics (among 7th graders)
The use of technology in the teaching and learning of mathematics
Transition from school to college mathematics
Research Title
How do students learn the abstract concepts behind differentiation and integration?
How do students learn Linear Algebra, and how should it best be taught?
Research title in question forms
1. Does the title precisely identify the area of the problem?
2. Is the title clear, concise, free from jargon, and adequately descriptive to permit indexing the study in its proper category?
3. Does the title identify the key variables and provide some information about the scope of the study?
4. Are unnecessary words, such as “a study of,” “an investigation of,” and “an analysis of” avoided?
5. Do nouns, as opposed to adjectives, serve as the key words in the title?
Questions to consider when contemplating a title
Research title comes from …..????
Research title comes from Research Problem(s)
Where does research titles come from
A research problem is a DISCREPANCY between what one knows and ought to know to solve a problem or to understand a phenomenon.
Research problems are EDUCATIONAL ISSUES OR CONCERNS studied by researchers.
A SITUATION OR CIRCUMSTANCE THAT REQUIRES A SOLUTION to be described, explained, or predicted. It is an unsatisfactory situation that wants you to confront.
A research problem refers to some DIFFICULTY that a researcher experiences in the context of either a theoretical or practical situation and wants to obtain a solution for the same.
Research problems are QUESTIONS THAT INDICATE GAPS in the scope or the certainty of our knowledge. They point either to problematic phenomena, observed events that are puzzling in terms of our currently accepted ideas, or to problematic theories, current ideas that are challenged by new hypotheses.
What is research problem?
Einstein: If I have one hour for solving the problem on which my life depends, I will devote 40 minutes to study the problem, 15 minutes to analyse it, and only 5 minutes to solve it.

Finding a research problem
In selecting the research question consider whether or not it is:
Feasible: in terms of time, place, money, equipment, subjects etc.
Interesting : The question has to be interesting to the investigator, but should also be interesting to others.
Novel: Has this study been done before? Does it add to the current body of knowledge?
Ethical: Can the study be done in a way that does not subject subjects to excess risks?
Relevant: Will it further knowledge in the related field? Will the results change practice, policy or point towards further avenues of research?
FINER framework
S – Specific M – Measureable A – Attainable R – Realistic T – Timely
Keep it (title) short and simple
SMART KISS
1. Is there a difference in the science achievement of boys and girls exposed to the same science activity?
2. Should we teach sex education in elementary school?
3. What happens if the school day becomes longer?
4. How do students adjust in a school environment?
Are these problems researchable?
2. What is the difference in knowledge and attitude of fifth graders taught sex education compared to fifth graders who are not taught sex education?
3. What is the relationship between length of the school day and learning achievement of high school students?
Are the following questions researchable? Is democracy a good form of government? Should values clarification be taught in public schools? Can crime be prevented? Should physical education classes be dropped from the high school
curriculum?
Reformulating the problems 2 and 3
A paradigm is a “worldview” or a set of assumptions about how things work.
“shared understandings of reality”; a set of beliefs about reality and knowledge that provides the researcher with a broad overview and direction of the research.
A paradigm encompasses three basic components – ONTOLOGY, EPISTEMOLOGY and METHODOLOGY.
Research Paradigm
Ontology is the starting point of all research after which one’s epistemological and methodological positions logically follow.
An individual’s ontological position is their answer to the question – What is the nature of reality and what constitutes reality.
Ontology
Epistemology – what is knowledge? What is the relationship between knowledge and reality and between knower and would-be-knower?
If there were no human beings, would there still be three basic types of rock? ,
Did the unconscious exist before Freud?
Methodology – procedural strategy for acquiring knowledge about the phenomena under study.
Positivism Interpretivism
Ontology Naïve realism (only one reality that is observable, measureable)
Relativism (multiple reality)
Epistemology Dualism/objectivism (the researcher and research participants and the topic are independent to each other, findings independent of the researcher
Subjective/transactional; Created findings (knowledge is socially constructed)
Methodology Controlled, ‘scientific’ experiment, measurement
Hermeneutical/dialectical, interaction
Two basic paradigms – Positivism and Interpretivism
Types of Research
ONTOLOGICAL◦ Existence of objective, absolute truths◦ Focus on operational definitions and rational explanations
EPISTEMOLOGICAL◦ Researcher (knower) and object of study (known) independent – focus
on objectivity◦ Assumption that inquiry can approximate objectivity (value-free);
disagreements between observers due to errors and/or observer biases METHODOLOGICAL
◦ Replicability as a means for testing truth◦ Focus on generalization◦ Criteria – notions of internal/external validity
Quantitative Research
ONTOLOGICAL◦ Reality is local and specific◦ Constructions cannot be absolutely true or correct (but can be less
sophisticated/informed)◦ Reality actively constructed rather than discovered
EPISTEMOLOGICAL◦ Researcher and object of study inherently dependent◦ Inquiry inherently value-bound◦ Multiple interpretations can be equally valid
METHODOLOGICAL◦ Focus on induction◦ Relative lack of emphasis on generality – use purposive samples◦ Criteria – trustworthiness, credibility, transferability, confirmability
Qualitative Research
A scientific investigation in which the researcher manipulates one or more independent variables, controls any other relevant variables, and observes the effect of the manipulations on the dependent variable(s).
Peer tutoring and cooperative learning in undergraduate mathematicsThe use of team-based learningBilingual teaching and learning in mathematicsPlay as a means of motivation in mathematics learning
Experimental Research
When the researcher can not manipulate independent variable; the research is conducted after variation in the variable of interest has already been determined in the natural course of events.
Do the students who work during their college year have lower grades than students who do not work?
What is the effect of single-parent homes on achievement?
Causal Comparative/Ex-post Facto
No manipulation, the researcher investigates how scores on one variable or variables rise or fall as scores on other variables rise or fall.

Correlation Research
Data are gathered by asking questions a group of individuals called respondents.
Longitudinal – Panel (same subjects are surveyed at different times), Trend (different people from the same general population are surveyed at different times).
Cross sectional – studies a cross section of a population at a single point in time.

Formative Research
An emergent inquiry which includes designing and testing particular interventions. Interventions embody specific theoretical claims about teaching and learning, and reflect a commitment to understanding the relationships among theory, designed artefacts and practices.
Continuous cycle of conceptualisation, design, enactment, analysis and redesign.
