Study Notes
Educational Research in Focus
- Educational research is a systematic process for gathering data and analyzing that data with a specific purpose. It is a scientific and disciplined inquiry for producing knowledge
- Educational research serves the twofold purpose of acquiring new knowledge and solving problems within the educational sphere
- Research in education can be acquired through various sources, including personal experience, expert opinion, multimedia materials, inductive reasoning, and deductive reasoning
The Characteristics of Educational Research
- Educational research is characterized by precision, a parsimonious explanation, probabilistic thinking, verification, empiricism, logical reasoning, and objectivity
Validity in Educational Research
- Validity in research refers to the extent to which the findings are justified and can be interpreted accurately.
- Internal validity measures the accuracy of interpretations within the research context, ensuring that results are a true reflection of the study's design.
- External validity evaluates the generalizability of findings to other populations and similar situations, assessing the applicability of results beyond the specific study.
Types of Research
- Action research: A type of applied research often conducted by educators to address specific issues or inform local level decision-making.
- Quantitative research: Employs numerical data and statistical analysis to examine relationships between variables and identify causes and effects in a field of study.
- Qualitative research: Focuses on understanding social phenomena through holistic inquiry and narrative descriptions, observing and analyzing data without predefined instruments.
Ethical Considerations in Research
- Confidentiality of information collected from research participants should be maintained unless agreed upon otherwise in advance.
- Researchers conducting studies through an institution must obtain permission from the institution before gathering data.
Selecting and Defining a Research Topic
- Choose a research topic that sparks your interest, is original, manageable in size, and holds significant value to the field of study.
- Consider your own capabilities, limitations, and available resources.
Transforming a Problem into a Researchable Question
- A teacher facing challenges with their students' negative attitudes towards physics, such as reluctance to complete assignments, can explore underlying causes.
- Potential contributing factors include:
- Difficulty level of textbooks or instructional materials
- Students' cognitive skills
- The abstract nature of physics concepts
- Teaching methods employed
- Teacher competence
- Influence of parental attitudes towards physics
