ENG518 Quiz Set 2

What is research?

• Research is a systematic process of investigating a topic or problem.
• It aims to discover new knowledge, validate existing ideas, or solve practical issues.
• Researchers gather data, analyze it, and draw conclusions.

General characteristics of research

• Rigorous: Research follows a structured approach with clear steps.
• Objective: It seeks unbiased information.
• Replicable: Others can repeat the study to verify results.

Functions of research

• Advancing knowledge: Research contributes to our understanding of ELT.
• Improving practice: It informs teaching methods and materials.
• Solving problems: Research addresses real-world challenges.

Specific characteristics of ELT research

• Focuses on language teaching and learning.
• Investigates language acquisition, classroom strategies, and learner needs.

Research in ELT (AL)

• ELT research explores language teaching theories and practices.
• It examines language skills, assessment, and teacher development.

What is ELT research about?/Why is research in ELT important?

Demythologizing research

• Demystifies complex research concepts.
• Makes research accessible to educators.

Identifying important questions in ELT

Classification of research

• Descriptive: Describes phenomena (e.g., language use in classrooms).
• Experimental: Tests hypotheses (e.g., effectiveness of a teaching method).

Major types of research

• Qualitative: Focuses on understanding context and meaning.
• Quantitative: Involves numerical data and statistical analysis.

Educational research

• ELT research falls under educational research.
• It informs educational policies and practices.

Scientific ways to solve problems

• Scientists use the scientific method to solve problems.
• It involves steps like making observations, asking questions, forming hypotheses, testing predictions, and iterating.
• The goal is to find evidence-based solutions.

Characteristics of an investigator

• Good investigators possess traits like curiosity, analytical thinking, and integrity.
• They ask the right questions, avoid groupthink, and cope effectively with challenges.

Assortment of a problem

• Assortment optimization is a common challenge in fields like retail, airlines, and healthcare.
• It involves selecting the right mix of items to offer (e.g., products in a store) to maximize an objective (like revenue).

Identification of a problem

• Problem identification is crucial.
• It pinpoints the root cause of a dilemma and helps create a clear problem statement.
• Researchers use it to focus their investigations.

Criteria for the selection of a problem

• A good research problem should be novel, significant, and well- defined.
• It must address a real obstacle and contribute original insights.
• Researchers should ask the right questions to tackle relevant problems.

Defining a Problem and Formulating a Hypothesis:

• A research problem sets the stage for investigation.
• A hypothesis is a testable explanation related to the problem.
• It guides research design and data collection.

Kinds of a hypothesis and Characteristics of a good hypothesis

• Hypotheses can be null (no effect) or alternative (predicting an effect).
• A good hypothesis is specific, testable, and based on existing knowledge.

Variables in a hypothesis

• Variables are factors that change in an experiment.
• Independent variables are manipulated, and dependent variables are measured.

How to locate research?

Researchers use various sources:

• Preliminary sources: Gather background information.
• Secondary sources: Explore existing research.

Locating primary research: exploring databases

• Primary research involves collecting original data for a specific study.
• To find primary sources, explore databases (like Google Scholar, PubMed, or Scopus).
• Look for research articles, interviews, surveys, or experiments conducted by researchers themselves.

LPR: Position papers vs primary research

• Position papers express opinions or stances on a topic.
• Primary research provides direct evidence (e.g., interviews, data) for analysis.
