Research Methodology: Educational Research

Define research as the formal, systematic application of method to study problems, targeting solutions and generating new knowledge while correcting errors through empirical observation and principled, careful description.

Explore the scientific method, including inductive and deductive reasoning, the steps from problem recognition to hypothesis and data analysis, and its educational applications.

Explore the steps of research from problem selection to data analysis and conclusions, and examine sources of knowledge and core ethics for responsible educational research.

Explore the main types of research—basic, applied, action, evaluation, and r&d—alongside historical, descriptive, and experimental methods, with emphasis on basic research conducted in laboratories and on animals.

Explore the definition of applied research, its field approach and classroom setting, and the features of action research led by educationists, focusing on teachers and classroom control levels.

Action research applies to local settings, targets solvable classroom problems, and aims to improve school practices; findings are implemented by teachers with low financing, yet it risks low quality.

Learn how to evaluate research through a systematic process of analyzing information to guide decisions, and explore whether the new experimental curriculum is better than the formal one.

Examine past events to explain causes, effects, and trends, anticipate future developments, and define problems, collect data, analyze, draw conclusions, and report findings with literacy campaigns as examples.

Descriptive research collects data to test hypotheses and answer status questions, outlining steps from identifying the problem to reporting findings, including population and sample size, instrument development, and pilot testing.

Explore historical research by studying past events to identify causes and effects, collecting data from primary and secondary sources, applying external and internal criticism, and reporting conclusions.

Identify the problem, review literature, and define population and sample for descriptive research; develop instruments, pilot test, analyze data, interpret results, and report findings from questionnaires, interviews, or observations.

Learn survey research design by using a data collection instrument to survey a population, with cross-sectional or longitudinal designs and sampling classifications such as cohort, Bennell, and Oxley's classification.

Casual comparative research compares preexisting groups to infer causes when variables are not manipulated, using descriptive statistics and inferential tests like analysis of variance, chi-square, and correlation.

Determine the relationship between two variables using a correlation coefficient, and recognize that correlation does not imply causation; outline problem selection, sampling, and a minimum of 30 subjects in design.

Explore data analysis by understanding the correlation coefficient, positive and inverse relationships, and how ranges like 0.60 to 0.70 support group predictions, while 0.80 and above support individual predictions.

Identify and distinguish independent variables as treatments or causes and dependent variables as the effect or response to manipulation, such as test score or errors, in educational research.

Explore experimental research by manipulating at least one independent variable and observing effects on the dependent variable while controlling extraneous factors; use experimental and control groups to test hypotheses.

Assess experimental validity by identifying threats to internal validity, such as history, maturation, testing, instrumentation, regression, differential selection, attrition, and threats to external validity like pretest effects and selection bias.

Explore qualitative and quantitative approaches as complementary methods in educational research, contrasting extended, holistic qualitative data and induction with numerical, generalizability-focused quantitative analysis.

Identify how to select a research problem, narrow the general area to a specific, searchable issue, and craft a clear statement with variables, purpose, and significance.

Explore the characteristics of a good research problem in educational research, including novel and original scope, interesting and significant aims, a searchable, feasible focus, data availability, and guidance.

Delimit the research problem by imposing geographic, time, institutional, and resource constraints for focus and feasibility. Justify the problem by showing results will improve educational quality and contribute to knowledge.

Define and formulate a hypothesis as a provisional, testable explanation for observed phenomena, consistent with previous research, assess the relationship between variables with data, and test within a reasonable time.

Explore inductive and deductive hypotheses, including null, directional, and non-directional forms, and explain their testing via sampling, design, and data analysis.
