TL;DR
This study explores integrating instructional scaffolding into search engines to support learning, testing three strategies, but finds limited impact on learning gains and some unintended user behaviors.
Contribution
It introduces and evaluates three novel scaffolding strategies within search systems to enhance learning support during information seeking.
Findings
Scaffolding methods did not significantly improve learning gains.
Scaffolding significantly influenced search behavior.
Immediate feedback led to focus on gauges rather than learning.
Abstract
Search engines are considered the primary tool to assist and empower learners in finding information relevant to their learning goals-be it learning something new, improving their existing skills, or just fulfilling a curiosity. While several approaches for improving search engines for the learning scenario have been proposed, instructional scaffolding has not been studied in the context of search as learning, despite being shown to be effective for improving learning in both digital and traditional learning contexts. When scaffolding is employed, instructors provide learners with support throughout their autonomous learning process. We hypothesize that the usage of scaffolding techniques within a search system can be an effective way to help learners achieve their learning objectives whilst searching. As such, this paper investigates the incorporation of scaffolding into a search…
