Origin of Method: is the Greek word “methodos” which consists of two parts: “meta”:“after”, and “hodos”: “road”

Methods = procedures = techniques = approaches = ways

Methodology is to analyse research methods

QUALITATIVE METHODS

Hypothesis: Hypothesis: If A happens, B would occur.A: the assumed cause (stimulus)

B: the assumed effect (response)

Cause and effect relationship/ causal relationship.

If A happens, B would occur.A: the assumed cause (stimulus)

B: the assumed effect (response)

Cause and effect relationship/ causal relationship.

Example of a Example of a hypothesishypothesis

If students use their metacognitive strategies, they would become autonomous learners.

Use of metacognitive strategies: the cause: independent variable. I.V

Autonomy: the effect: dependent variable. D.V

If students use their metacognitive strategies, they would become autonomous learners.

Use of metacognitive strategies: the cause: independent variable. I.V

Autonomy: the effect: dependent variable. D.V

The null hypothesis: The null hypothesis: HH00

What people believe is true. But the researcher thinks it’s false. Example:

If students work in groups (co-operative learning), their writing proficiency would be high.

The alternative The alternative hypothesishypothesis H H11

What the researcher believes is true. It is his/her research hypothesis. Eg.

If students work individually, their writing proficiency would increase.

Because s/he thinks that: if students work in groups, their writing proficiency would decrease.

QUANTITATIVE METHODSQUANTITATIVE METHODS

QUALITATIVE QUALITATIVE METHODSMETHODS

Descriptive method

Historical method

CORRELATIONAL METHODCorrelation = the relationship between two variables.

When do we follow this method?

When both variables are countable/ measurable.

Eg. Intelligence and academic achievement.

DESCRIPTIVE METHODDESCRIPTIVE METHODWhen?1. When one variable is uncountable.

Eg. Attention in the classroom and academic achievement.

2. When the two/both variables are uncountable.

Eg. CALL and motivation.3. When we have one variable: students’ lack of vocabulary.

EXPERIMENTAL EXPERIMENTAL METHODMETHOD1. When something doesn’t exist.

2. When we can realize it: feasibility/practicability of research.

3. When we cannot count the correlation coefficient. Eg. Cooperative learning and high writing proficiency.

« r »: coefficient of « r »: coefficient of correlationcorrelation

If r is near +1 or -1 the correlation is high. (0.95; 0.8; -0.7...)

If r = +1 or -1 the correlation is strong/perfect/high.

If r is between “+/- 0.25” and “+/- 0.75” it is a moderate correlation.

If r is near 0 the correlation is weak If r = 0 there is no correlation: no relationship between variables

If r is near +1 or -1 the correlation is high. (0.95; 0.8; -0.7...)

If r = +1 or -1 the correlation is strong/perfect/high.

If r is between “+/- 0.25” and “+/- 0.75” it is a moderate correlation.

If r is near 0 the correlation is weak If r = 0 there is no correlation: no relationship between variables

If r is positive (marked by +) this means that if “x” increases ,“y” also increases.( linear relationship)

if “r” is negative (marked by -) this indicates that if “x” increases, “y” decreases.

X: 1st variable: causeY: 2nd variable: effect

MIXEDMIXED METHODSMETHODSThe Experimental-correlational method (two methods)

When? When we can conduct an experiment + we can count correlation coefficient.

E.g. the influence of using collocations on students’ writing proficiency.

Experiment: teaching collocations

At least 2 groups:1.The experimental group

2.The control group

1.The experimental group: It receives the experiment = treatment = intervention

Example: If we teach students grammar, their writing proficiency would raise.

Teaching grammar is the experiment.

1.The experimental group: It receives the experiment = treatment = intervention

Example: If we teach students grammar, their writing proficiency would raise.

Teaching grammar is the experiment.

2.The control group: it doesn’t receive the experiment/treatment. It’s a comparison group (we don’t teach them grammar)

Why do we need this group? to compare the results of the experimental group to those of the control group in order to see whether the experiment was effective. If the writing proficiency of the experimental group has raised.the experiment was effective (successful)

Example: Analysis of data driven from students’ questionnaire

A questionnaire has been administered to collect information from first year students of English who have been allocated randomly to two groups: an experimental group that will receive the treatment and a control one which stands as a means of comparison to see whether the treatment has come to any changes. The aim behind this questionnaire is to collect data about students’ level in writing and their knowledge of collocations.
