Research Methods Simulations
A collection of interactive 3D visualizations and simulations to help you master concepts in research methods.
Introduction to Research Methods - Theory & Concepts
An overview of research methods, defining the purpose of research, types of research, philosophical foundations, and the general research process.
Interactive Research Process
Identify Problem
Recognize a gap in knowledge or a practical issue.
Formulating the Research Problem - Theory & Concepts
Identifying research gaps, writing problem statements, setting objectives and questions using the FINER, PICO, and SMART frameworks.
Identifying Research Gaps
Existing Knowledge (The Literature)
- Compressive strength of standard concrete
- Basic properties of steel rebar
The Research Gap (What is Unknown)
- Long-term durability of 3D-printed concrete in marine environments
- Self-healing concrete performance under extreme freeze-thaw cycles
Literature Review - Theory & Concepts
Purpose and scope of a literature review, Boolean search strategies, systematic and scoping literature reviews, Reference Management Software, and avoiding plagiarism.

Research Design and Methodology - Theory & Concepts
Understanding experimental, non-experimental, and mixed-methods research designs, along with civil engineering-specific data collection and sampling techniques.
Interactive Sampling Methods
Total Population: 100
Sample Size Selected: 0
Validity and Reliability - Theory & Concepts
Defining validity and reliability, measurement errors, types of validity (construct, content, criterion), and understanding Type I and Type II errors.
Validity vs. Reliability Target Simulation
Select a scenario to visualize how data points group on a target. The bullseye represents the true value (Valid). Grouping tightly represents consistency (Reliable).
The points are scattered everywhere. You are neither hitting the bullseye nor hitting the same spot consistently.
Data Analysis and Interpretation - Theory & Concepts
Statistical methods for civil engineering research, including descriptive and inferential statistics, hypothesis testing, regression analysis, machine learning, and software tools.
Measures of Central Tendency Explorer
Select a data distribution to see how the Mean, Median, and Mode are affected. Notice how extreme values (outliers) in skewed distributions pull the mean away from the median and mode.
Relationship: Mean = Median = Mode
Research Ethics and Integrity - Theory & Concepts
Ethical Principles in Human and Animal Research, Plagiarism, Falsification, Fabrication, Informed Consent, Confidentiality, Data Management Plans, and Open Science.
Interactive Ethics Scenario
The Retaining Wall Dilemma
Context: You are a geotechnical researcher conducting lab tests on the shear strength of a new soil stabilization additive. You've been working on this for 6 months and need strong results to publish in a high-impact journal, which will secure your next grant.
The Conflict: In your final set of 10 tests, 8 show significant improvement in shear strength (supporting your hypothesis), but 2 tests inexplicably failed dramatically. Including these 2 failures will lower the average performance, potentially making the results non-significant statistically.
What should you do?
Writing and Presenting Research - Theory & Concepts
The IMRaD structure of research reports, citation styles, grant proposals, peer-review process, Open Access vs. Traditional publishing, and plagiarism checking.
