Scaffolding Critical Thinking with Generative AI
Vendrell & Johnston (2026) propose a design-oriented framework for LLM use in higher education that strengthens rather than displaces Critical Thinking, countering Cognitive Offloading and metacognitive disengagement (Metacognition, Scaffolding).
Vendrell & Johnston (2026) propose a design-oriented pedagogical framework for integrating LLMs into higher education in ways that strengthen rather than displace critical thinking. Drawing from cognitive psychology, educational theory, and AI ethics, the framework addresses the risk that unstructured LLM use leads to cognitive offloading, metacognitive disengagement, and reduced epistemic agency.
The Problem: Unstructured LLM Use
A global survey reports 86% of university students now use AI in their studies, with over half engaging weekly — primarily for summarization, grammar checking, and drafting (Digital Education Council, 2024). However, LLMs are not designed with educational goals in mind; they simulate understanding via probabilistic language modeling without intentionality or comprehension.
Research shows that unguided AI use correlates with:
However, when students first engage independently before consulting AI, their outputs are significantly stronger (Kosmyna et al., 2025). This mirrors earlier technology integrations — calculators, search engines — where effects depend on pedagogical design, not the tool itself.
Six Essential Processes
The framework identifies six interconnected cognitive and metacognitive processes that must be deliberately supported in AI-enhanced learning environments:
| Process | Definition |
|---|---|
| 1. Conceptual interpretation | Actively constructing meaning by selecting, organizing, and integrating information; distinguishing core ideas from peripheral details. Aligned with Bloom's "Understand" and "Analyse" levels. |
| 2. Inferential reasoning | Generating warranted conclusions from evidence; identifying assumptions, discerning logical relationships, and predicting implications. The cognitive bridge between information and action. |
| 3. Evaluative judgement | Assessing credibility, coherence, and evidentiary support of claims. What Bielik & Krell (2025) call epistemic vigilance — the capacity to critically assess both source credibility and claim validity. |
| 4. Metacognitive regulation | Monitoring, evaluating, and strategically controlling one's cognitive processes. Transforms critical thinking from episodic acts into sustained, self-directed practice. |
| 5. Intellectual curiosity | The motivational disposition to explore ideas, ask questions, and pursue knowledge beyond instrumental goals. Fuels cognitive persistence and epistemic openness. |
| 6. Epistemic integrity | The ethical orientation to seek truth, evaluate claims fairly, and engage with complexity conscientiously. Combines intellectual honesty with critical reflexivity. |
Eight Design Principles
| Principle | Core Mechanism | Supported Processes |
|---|---|---|
| P1. Preserve cognitive friction | Require independent thinking before AI; use AI to generate counterarguments | Conceptual interpretation, Inferential reasoning |
| P2. Scaffold LLMs as thinking partners | Position LLMs as provisional collaborators, not authoritative sources | Inferential reasoning, Curiosity, Epistemic integrity |
| P3. Embed evaluation as standard practice | Structured checkpoints for cross-referencing and criteria-based assessment | Inferential reasoning, Evaluative judgement |
| P4. Activate metacognitive self-regulation | Planning templates, reflective journals, AI prompt logs | Metacognitive regulation |
| P5. Encourage intellectual humility and curiosity | Examine AI limitations, explore alternative perspectives, identify omissions | Curiosity, Epistemic integrity |
| P6. Foster epistemic integrity | Require justification of claims, multiple perspectives, reasoning under uncertainty | Epistemic integrity |
| P7. Align assessment with intended cognition | Reward reasoning quality over surface fluency; assess how students interpret, question, and integrate AI content | Evaluative judgement, Metacognitive regulation |
| P8. Balance AI-mediated and AI-free phases | Sequence pre-AI, during-AI, and post-AI activities; deliberate AI-free zones | Conceptual interpretation, Metacognitive regulation |
Connection to Existing Frameworks
This model aligns with the Principled AI Education principle of augmenting rather than displacing human cognition. The emphasis on sequencing echoes findings in Tutoring Specific Vs General AI that pedagogically-designed AI outperforms raw LLM chatbots on learning outcomes. The metacognitive focus connects to Self Regulated Learning cycles of planning, monitoring, and evaluation, while drawing on feedback literacy principles (Carless & Boud, 2018).
P1's use of counterarguments as cognitive stimuli parallels the Socratic AI Dialogue approach of using questions to foster expert-like reasoning. P7's assessment alignment extends Formative Assessment principles into AI-mediated contexts, and the emphasis on preserving learner agency connects to AI Learning Companions Framework which prioritizes learning over performance. The focus on epistemic integrity and the risk of over-reliance also speaks to Transfer Of Learning — the central question of whether AI-assisted gains persist when tools are removed.
P2's scaffolded positioning of LLMs aligns with AI Literacy frameworks that progress from understanding to critical engagement to creative application, and the framework's overall design-based research methodology parallels the evidence standards discussed in Stanford Evidence Base AI K12 2026.
Practical Application
Two illustrative scenarios demonstrate implementation:
Scenario A: Prompt Crafting and Critique. Students draft prompts individually without AI access, predict possible responses and limitations, analyze outputs using structured criteria (Which perspectives are prioritized? What is absent? What claims lack justification?), revise prompts with reflection, and identify ethical implications of prompt framing.
Scenario B: AI-Mediated Debate and Synthesis. Students engage in structured debate with AI as a provisional interlocutor, followed by independent written synthesis requiring assumption identification, counterargument consideration, and integration of AI-generated content with original reasoning.
Both scenarios emphasize the critical sequence: independent thinking first, AI interaction second, reflective integration third.
