Description

The article operationalizes germane load as learning effects: the portion of working memory resources devoted to schema construction during a learning phase, whose behavioral signature is improvement on post-test problems. As the article states, "germane load assigned in the learning phase was evaluated based on the increase of the test scores." This measurement approach treats pre- to post-test gains as the index of germane load, and the article uses it to distinguish two types of germane load related to intrinsic load.

Design Implications

Context

Requirements

• A pre-test/post-test design so that score increases can be computed as the measure of germane load

Constraints

Target Learners

• novice learners

Target Learning Objectives

• schema construction

Claims

• Under high extraneous load (hint presentation and L and rL condition), no test-score increases were observed on identical or near-transfer problems [~W]
• Per-question pre/post analysis showed significant improvement on almost all questions, with Q1 (DBMS use) and Q4 (basic normalization) as exceptions due to high pre-test scores [+W]
• Only the high-dose VSDR group showed statistically significant improvement in ICT subject knowledge, from pre-test to post-test [~W]
• Pre-test/post-test learning gains showed no significant difference compared to a control group [-W]
• Students' overall biology knowledge showed only a slight, statistically non-significant increase [-W]
• Students demonstrated significant improvement in genetics knowledge from pre-test to post-test after playing Geniventure [+W]
• Students improved significantly from pre- to post-test in both topics, with a medium effect in experimental design and a small effect in graphing [~W]
• Germane load measurement is problematic: GCL-outcome correlations and item understanding show weaknesses across instruments [-W]
