Educational technology Study Guide

📖 Core Concepts Educational Technology (EdTech) – The study and ethical practice of using tech processes & resources to facilitate learning and improve performance. Instructional Technology – Theory & practice of designing, developing, using, managing, and evaluating learning resources. Learning Theories – Behaviorism (rewards/punishments), Cognitivism (information processing, memory models), Constructivism (learners actively build meaning). Blended / Hybrid Learning – Combines face‑to‑face instruction with online components; distributed learning can refer to the online portion or a fully online mode. Synchronous vs. Asynchronous – Real‑time interaction vs. self‑paced activities (forums, recordings, LMS). Flipped Classroom – Content consumed at home; class time devoted to higher‑order tasks (problem‑solving, discussion). Learning Management System (LMS) – Software that delivers, tracks, and manages training/education activities. Intelligent Tutoring System (ITS) – AI‑driven program that models learner knowledge & provides immediate, personalized feedback; keeps learners in their Zone of Proximal Development (ZPD). ADDIE Model – Instructional design framework: Analysis → Design → Development → Implementation → Evaluation. Digital Divide – Unequal access to technology based on socioeconomic, geographic, or demographic factors. 📌 Must Remember Behaviorism → programmed instruction (Skinner). Cognitivism → Atkinson‑Shiffrin & Baddeley models; cognitive load matters. Constructivism → teacher as facilitator; well‑structured environments for novices, ill‑structured for experts. Flipped Classroom pros: ↑ performance, satisfaction, interaction; cons: motivation, internet equity, prep workload. ITS advantage: one‑on‑one tutoring > group teaching; adapts to ZPD. Formative assessment: removes wrong answers, explains before practice. Summative assessment: new set of items covering taught material. Learning Analytics → logs → dashboards → self‑regulated learning improvements. Digital privacy risk: extensive personal data (browsing, location, behavior) often collected without parent awareness. 🔄 Key Processes ADDIE Instructional Design Analysis: Identify learners, goals, constraints. Design: Draft objectives, assessments, media. Development: Build/author content, reusable learning objects. Implementation: Deploy via LMS or virtual classroom. Evaluation: Formative (ongoing) + summative (final) review. Flipped Classroom Workflow Pre‑class: Publish video/interactive module → students engage independently. In‑class: Conduct problem‑solving, discussion, application activities. Post‑class: Use clickers or LMS quizzes for immediate feedback. ITS Adaptive Questioning Diagnose current knowledge → select next item just above mastery (ZPD) → provide instant feedback → update learner model. Learning Analytics Cycle Capture activity data → transform into metrics (login frequency, time‑on‑task) → visualize (graphs, dashboards) → students self‑assess → adjust study strategies. 🔍 Key Comparisons Behaviorism vs. Cognitivism – Rewards & punishments vs. mental processing & memory structures. Synchronous vs. Asynchronous – Real‑time interaction vs. self‑paced, flexible timing. Blended Learning vs. Fully Online (Distance Learning) – Mix of face‑to‑face vs. entirely remote. Formative Assessment vs. Summative Assessment – Ongoing feedback, error correction vs. final evaluation of learned material. Intelligent Tutoring System vs. Traditional E‑learning – Personalized, adaptive feedback vs. static content delivery. ⚠️ Common Misunderstandings “E‑learning = only computers.” It includes mobile devices, social platforms, and AI‑driven tools. “Flipped means just watching videos.” The core is using class time for active, higher‑order work. “All MOOCs give credit.” Most are free, non‑credit; completion rates are low due to isolation. “More tech automatically improves learning.” Effective use requires alignment with pedagogy, feedback, and cognitive load considerations. “Privacy isn’t an issue in schools.” Device monitoring can collect sensitive data, raising legal & ethical concerns. 🧠 Mental Models / Intuition “Feedback Loop” – Immediate feedback → error detection → rapid correction → stronger memory trace (applies to clickers, ITS, formative quizzes). “Zone of Proximal Development” – Imagine a ladder: current ability = rung you stand on; ITS lifts you one rung higher, never too far above. “Chunk‑and‑Sequence” – Break content into reusable learning objects (chunks) and arrange them according to the process (ADDIE phases). 🚩 Exceptions & Edge Cases Hybrid Learning – May refer to distributed learning (online component only) or a fully blended model; read context. Adaptive ITS – Not all systems truly model emotions or off‑task behavior; effectiveness varies by implementation. Mobile Learning – While it expands access, early‑age excessive screen time can delay developmental milestones. 📍 When to Use Which Choose Behaviorist approaches when training requires clear, observable outcomes (e.g., safety protocols). Apply Cognitivist strategies for complex problem solving that demands memory management (use worked examples, segmenting). Use Constructivist activities for advanced learners or project‑based units where prior knowledge can be leveraged. Select Synchronous tools for discussions, labs, or real‑time feedback; asynchronous for content delivery and reflection. Deploy ITS when individualized tutoring is needed but human one‑on‑one is impractical. Implement LMS analytics when you need to identify at‑risk students early (low login frequency, poor quiz scores). 👀 Patterns to Recognize Repeated low‑score on a single concept → ZPD gap → consider ITS or targeted remediation. High clicker participation but low post‑test scores → superficial engagement; need deeper cognitive tasks. Dropout spikes in MOOCs after week 3 → isolation; add peer forums or instructor presence. Multiple distractions reported in surveys → possible over‑stimulation; redesign media density. 🗂️ Exam Traps “All online learning is asynchronous.” Exam items may list asynchronous as a characteristic of any e‑learning; remember synchronous options exist. “MOOCs always grant academic credit.” Correct answer: most do not provide credit. Confusing blended with distance learning. Blended includes face‑to‑face; distance is fully remote. Assuming “digital divide” only concerns hardware. It also includes internet bandwidth, digital literacy, and socio‑economic factors. Attributing “immediate feedback” solely to clickers. ITS and computer‑aided assessment also deliver instant feedback. --- Use this guide for rapid review: focus on definitions, core models (ADDIE, learning theories), key instructional formats (blended, flipped, synchronous vs. asynchronous), technology tools (LMS, ITS, analytics), and the main pros/cons that frequently appear in exam stems.
