Pre-Service Teacher Conceptual Change Scores with RADEC and Virtual Lab Intervention

78 pre-service elementary teachers' pretest and posttest scores and qualitative conception levels from a 2025/2026 academic year study. Henni Riyanti published the dataset on figshare in April 2026. The embedded experimental design involved an experimental group of 39 students and a control group of 39 students.

Use Cases

• Compare conceptual gain scores between experimental and control groups based on pretest and posttest data
• Analyze the correlation between normalized gain scores and qualitative levels of conception derived from coding
• Evaluate student engagement and understanding based on qualitative responses to RADEC-based learning with virtual laboratory assistance
• Model the efficacy of technology-enhanced pedagogical interventions in teacher education programs

Strengths

• Data from a controlled embedded experimental design with 78 participants split into equal experimental and control groups
• Mixed-methods approach integrating quantitative test scores and qualitative conception levels
• Focus on a specific cohort of 600 first-semester students in an Elementary Teacher Education Program

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect temporal and institutional bias inherent to a single university study
