DEFINITION OF TERMS || PRACTICAL RESEARCH 2

Summary

This video lesson instructs on defining key terms in research studies to ensure a shared understanding among readers. It outlines two types of definitions: conceptual, which is akin to textbook or dictionary definitions and often quoted from literature; and operational, which specifies how a concept is measured in a study. The video uses an example of a research title to illustrate operational definitions of terms like 'approach' and variables, emphasizing the importance of clear communication in research.

Takeaways

• 📚 **Define Key Terms Upfront**: It's important to define key terms in your research at the beginning to ensure everyone has a shared understanding.
• 🔍 **Find Definitions by Reading**: Look for definitions in existing literature to understand how terms are commonly defined in your field.
• 📈 **Conceptual Definition**: This is the scientific definition of a concept, often found in textbooks or dictionaries, and is used to systematically measure a variable or construct.
• 🔧 **Operational Definition**: This defines a concept in terms of the methods used to measure it, ensuring a clear and agreed-upon definition for research purposes.
• 📝 **Cite Conceptual Definitions**: When presenting a conceptual definition, it should be quoted verbatim with the reference and page number.
• 🤔 **Multiple Conceptual Definitions**: Be aware that there might be more than one conceptual definition for a construct, and it's important to consider these variations.
• 📊 **Operational Definition Clarity**: Having an operational definition helps prevent disagreements about the meaning of concepts within a study.
• 📋 **Communication Tool**: Operational definitions facilitate clear communication among researchers about the concepts they are studying.
• 📖 **Example in Research Title**: The script provides an example of defining terms in the context of a research title about an approach and its effect on mathematics proficiency.
• 👨‍🏫 **Structure of Definition**: It's recommended to write a short introductory statement followed by the operational definitions of the terms in alphabetical order.

Q & A

What is the purpose of defining terms in a research study?

Defining terms in a research study is essential to ensure that all participants have a shared understanding of key concepts, which helps in the systematic measurement and communication of those concepts.

According to the video, where can one find ideas for definitions in their research?

One can find ideas for definitions by reading around the topic, which includes reviewing literature and consulting textbooks or dictionaries.

What is the difference between a conceptual definition and an operational definition?

A conceptual definition is a general explanation of a concept, often found in textbooks or dictionaries, while an operational definition specifies how a concept will be measured or observed in a specific research study.

Why is it important to present a conceptual definition word for word with the associated reference and page number?

Presenting a conceptual definition word for word with the associated reference and page number ensures academic integrity and allows readers to trace the source of the definition for further understanding.

Can there be more than one conceptual definition for a construct?

Yes, there can be more than one conceptual definition for a construct, which is why it's important to specify which definition is being used in a particular research study.

What role does an operational definition play in a research study?

An operational definition plays a crucial role in a research study by defining a concept in terms of the methods used to measure it, which helps in the standardization and replication of the research.

How does an operational definition help in research communication?

An operational definition helps in research communication by providing a clear, agreed-upon definition of concepts, which reduces ambiguity and facilitates consistent discussions among researchers.

What is the significance of defining terms alphabetically in a research study?

Defining terms alphabetically in a research study provides a systematic and organized way to present the definitions, making it easier for readers to locate and understand each term.

Why is it necessary to define independent and dependent variables in a research study?

Defining independent and dependent variables is necessary because these are the key components of an experiment. The independent variable is what the researcher manipulates, and the dependent variable is what is measured to observe the effect of the independent variable.

What is the role of the research title in defining terms?

The research title often includes key terms that need to be defined to provide context and clarity for the reader, ensuring that the scope and focus of the study are well understood.

How can defining terms help in learning and understanding a research study?

Defining terms helps in learning and understanding a research study by providing clear and precise meanings of the concepts used, which is crucial for grasping the study's methodology, results, and implications.
