## When to Trigger

Activate this skill when the user mentions:
- Pedagogical methods, teaching strategies, instructional design
- Learning analytics, student performance data, LMS data
- Assessment design, test validity, reliability, item analysis
- Curriculum development, learning objectives, Bloom's taxonomy
- Educational technology, e-learning, blended learning, MOOCs
- Educational interventions, quasi-experimental designs in education
- Student engagement, motivation, self-regulated learning

## Step-by-Step Methodology

1. **Define the research question** - Specify the educational context (K-12, higher education, professional development). Identify the intervention, outcome measures, and comparison conditions. Frame using established educational theory (constructivism, connectivism, cognitive load theory).
2. **Study design** - Select appropriate design: RCT (gold standard but often impractical), quasi-experimental (difference-in-differences, regression discontinuity), or mixed methods. Address common challenges: nested data (students within classrooms), selection bias, contamination between groups.
3. **Assessment development** - Define learning objectives using Bloom's taxonomy (remember, understand, apply, analyze, evaluate, create). Develop assessment items aligned with objectives. Compute reliability (Cronbach's alpha, test-retest, inter-rater). Conduct item analysis (difficulty, discrimination index).
4. **Data collection** - Gather quantitative data (test scores, grades, completion rates, time-on-task from LMS logs) and qualitative data (surveys, interviews, observations, think-alouds). Ensure IRB approval for human subjects research.
5. **Multilevel analysis** - Use hierarchical linear modeling (HLM) to account for nested data structure (students within classrooms within schools). Report ICC (intraclass correlation) to justify multilevel approach. Include relevant covariates (prior achievement, demographics).
6. **Effect size and practical significance** - Report Cohen's d or Hedges' g for group comparisons. Use standards for education research: d = 0.2 (small), 0.4 (medium), 0.6 (large). Translate to months of learning gain for K-12 contexts (What Works Clearinghouse approach).
7. **Evidence synthesis** - Situate findings within existing evidence base. Reference systematic reviews (What Works Clearinghouse, EPPI-Centre, Campbell Collaboration). Discuss generalizability, implementation fidelity, and scalability.

## Key Databases and Tools

- **ERIC (Education Resources Information Center)** - Education literature database

- **PISA / TIMSS / NAEP** - International and national assessment data
- **Google Scholar** - Cross-disciplinary search
- **R lme4 / HLM software** - Multilevel modeling
- **Canvas/Blackboard APIs** - LMS data extraction

## Output Format
