EXPERIMENTAL EVALUATION AND METHODOLGYCN505- ENVIRONMENTAL

PROJECT 1

METHODOLOGY

WHAT IS RESEARCH METHODOLOGY

Research Methodology is a way to find out the result

of a given problem on a specific matter or problem

that is also referred as research problem.

In Methodology, researcher uses different criteria for

solving/searching the given research problem.

Different sources use different type of methods for

solving the problem.

If we think about the word “Methodology”, it is the

way of searching or solving the research problem.

(Industrial Research Institute, 2010).

RESEARCH METHODOLOGY AND

ITS IMPORTANCE

In Research Methodology, researcher always tries

to search the given question systematically in our

own way and find out all the answers till conclusion.

If research does not work systematically on

problem, there would be less possibility to find out

the final result.

For finding or exploring research questions, a

researcher faces lot of problems that can be

effectively resolved with using correct research

methodology (Industrial Research Institute, 2010).

TYPES OF RESEARCH METHODOLOGY

TYPES OF RESEARCH METHODOLOGY

STAGE OF RESEARCH METHODOLOGY

TYPES OF METHODS

DESIGN OF SAMPLING

9

Feedback from sampling,

analysis and interpretation

Select methods for sample preservation

Select methods for collecting samples

Select appropriate analytical method

Select number of samples

and time/frequency of sampling

Select determinands

and sampling positions

Definition of objectives

SAMPLING STRATEGY Samples must be representative of;

• the bulk material (body) being sampled

• temporal variations

• spatial variations

Discrete (or Random/Grab) – does not account for

variation in spatial environment or time

Composite – pooled number of discrete samples

Systematic (or Grid/Transect) - a planned samplingstrategy to accomplish a specific objective

(Pseudo)Continuous – ongoing monitoring to e.g.establish baseline values for the environment and/or

evaluate changes

METHODS & MATERIALS

Describe precisely how the experiments are to be done.

Proper citations – record author(s), year, journal title, volume, page numbers.

Are the experiments ‘DO-ABLE’ here in our laboratories? Discuss with your supervisor!

List chemical requirements and place order early!

WHY NEED PLANNING

Prepare a time-line for the project – Gantt chart - must take into account holidays, exams, writing-up, submission dates.

Very little time. so preparation must be meticulous – there may not be time for repeat experiments.

Experiments must be so designed such that results can be presented either graphically or tabulated and amenable for statistical analyses

WHY NEED PLANNING (Cont..)

Implementation Issues:

A lot of assignments, lab reports, mini-projects, site visits, quizzes and tests during semester;

Project Title not clear;

Project has ≥ 2 Objectives

Delays due to:

Broken Equipment

Strong Demand for Equipment

Missing Chemicals

Limited Access to Research Journals

Limited / no access to Company Data (Confidentiality)

Lab not open after working hours

Person not contactable.
