Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The teacher decreased task complexity for the TW group, who were struggling to understand the situation, and increased task complexity for the technology group to further challenge their problem-solving abilities. → Lu 2010
Evidence¶
Lu 2010¶
Lu, J., Lajoie, S. P., & Wiseman, J. (2010). Scaffolding problem-based learning with CSCL tools. Computer-Supported Collaborative Learning, 5, 283–298. https://doi.org/10.1007/s11412-010-9092-6
q2 · i? · qualitative · r3
Qualitative analysis of scaffolding strategies in the Results section, illustrated by an excerpt in which the nurse responds to a chest X-ray request by reporting worsened blood pressure, heart rate, respiratory rate, oxygen saturation, temperature, and mental state.
"The teacher decreased the task complexity for the TW group because they were struggling to understand the situation and increased the task complexity for the technology group to further challenge their problem-solving abilities which were facilitated and improved by technology (Lu and Lajoie 2008)."
Discussion¶
Related Claims¶
- Co-regulation led to shared understandings with effective patient management as a result (Lajoie and Lu) — related
- Teacher discourse shifted toward creating new challenging situations (NI) and confirming repeats (R) in the interactive-whiteboard condition, versus providing requested information (IR) and clarification questions (Q) in the traditional-whiteboard condition — related
- The IW-supported group needed less teacher scaffolding in the late problem-solving stage, where nurse and instructor discourse decreased, while scaffolding increased from early to late stage in the TW condition — related
