Educational Technology (CFD 3890) - Unit 1

Fundamentals and Scope of Educational Technology

  • Verbatim and Formal Definitions:
    • Educational Technology (ET): Defined by Leith (1967) as the systematic application of scientific knowledge about teaching-learning conditions of learning to improve the efficiency of teaching and training.
    • AECT Definition: Januszewski and Molenda (2008) define Educational Technology as the study and ethical practice of facilitating learning and improving performance by creating, using, and managing appropriate technological processes and resources.
    • Core Distinction: Instructional Technology represents the physical tool or resource, whereas Educational Technology denotes the procedural framework and systematic process for utilizing that tool.
  • Essential Objectives and Purpose:
    • To enhance pedagogy and enable students to learn effectively.
    • To improve the overall quality of education and enhance the learning process through the effective use of technological tools.
    • To magnify the teaching and learning process while facilitating higher performance across educational systems by emphasizing both effectiveness and efficiency.
  • Encompassed Sub-Domains:
    • E-learning, instructional technology, Information and Communication Technology (ICT) in education, EdTech, learning technology, multimedia learning, and technology-enhanced learning (TEL).
    • Computer-based instruction (CBI), computer-managed instruction, and computer-based training (CBT).
  • Dual Aspects of Educational Technology:
    • Physical Hardware: The tangible technological devices, infrastructure, and delivery media utilized in classrooms.
    • Educational Theoretics: Theoretical hypotheses, conceptual frameworks, and analytical models concerned with application, interpretation, and the intrinsic purpose of learning rather than pure physical implementation.
  • Discrete Dimensions of Development:
    1. Theory and Practice: Educational approaches and systematic frameworks applied directly to learning.
    2. Technological Tools and Media: Media assisting in the communication, development, and exchange of knowledge.
    3. Learning Management Systems (LMS): Digital platforms facilitating student tracking, course delivery, and learning administration.
    4. Educational Subjects: Formal academic curricula such as Computer Studies and ICT courses.
  • Facilitative vs. Controlling Approach:
    • Educational technology functions as a facilitative mechanism rather than a controlling one; it claims to facilitate learning activities rather than cause or rigidly dictate them.
    • Facilitation encompasses the intentional design of learning environments, systematic organization of resources, and the provision of appropriate learning tools.
    • Environments range from traditional face-to-face settings and virtual environments to microworlds, augmented realities, distance learning setups, and specialized learning designs.
  • Levels of Teaching Organization:
    • Memory Level: Focuses on direct recall, rote learning, and factual recognition.
    • Understanding Level: Focuses on comprehending concepts, seeing patterns, and grasping underlying principles.
    • Reflective Level: Focuses on critical thinking, problem-solving, self-analysis, and higher-order cognitive processing.
  • Core Concepts of Technology:
    • Trade-offs, resources, systems, processes, optimization, control, and requirements.

Historical Evolution of Educational Technology

  • Theoretical Etymology:
    • The term technology implies the systematic application of science to art. Educational technology emerges when the science of learning and communication is formally applied to instructional practice.
    • The field functions as a child of both theoretical knowledge and practical knowledge, developing continuously through interactions between foundational research, psychological theory, and technological capabilities.
  • Chronological Development and Key Milestones:
    • Ancient to Mediaeval Foundations: Writing slates and blackboards have been utilized in educational settings for over a millennium. Early binary abacuses were employed to illustrate how computational systems manipulate numbers.
    • Early 1900s (Reiser, 2001): Traces the systematic roots of modern instructional technology back to the early twentieth century.
    • 1910: The first catalogue of instructional films was produced in the United States, giving rise to the "visual instruction" movement along with dedicated professional organizations and academic journals.
    • 1920s (Cuban, 1993): Classroom adoption of motion picture films and radio broadcasts initiated widespread visual and auditory instruction.
    • World War II Era: The addition of sound to motion pictures birthed "audiovisual instruction." Extensive utilization of military training films provided empirical and theoretical data regarding media's direct contributions to learning efficiency.
    • 1950s and 1960s: Educational television emerged as the primary technological focus for instructional delivery.
    • Late 20th Century: Slide and overhead projectors achieved ubiquitous institutional adoption. Computers emerged as the primary transformational technology, eclipsing television.
    • 1990s and Web Era: Video conferencing developed as a crucial forerunner to modern tele-education. The advent of the World Wide Web enabled multi-object-oriented sites (text-based virtual reality systems) and dedicated course websites.
    • CALCampus: Established the first fully online school curriculum, offering real-time classroom instruction, online examinations, testing, and automated assessments.
    • 21st Century Paradigm: Computer-mediated communication (CMC) forms the prevailing model, wherein primary pedagogical interactions between learners and educators are mediated by computational infrastructure. Major high-tech corporations (including Google, Verizon, and Microsoft) actively fund educational technology integration.

Domain Models and Frameworks of Instructional Technology

  • AECT Conceptual Framework:
    • Formally defined by the Association for Educational Communications and Technology (AECT) as the theory and practice of design, development, utilization, management, and evaluation of processes and resources for learning.
  • Seels and Richey (1994) Five Domains Model:

Five components of educational technology

Learning Theories and Pedagogical Frameworks

  • Interdependence of Theory and Research:
    • Theory guides research; research informs theory. Theory acts as a generalized concept offering systematic explanations for existing phenomena, while research expands the knowledge base.
    • Learning theories provide verification for instructional strategies, establishing predictable relationships between learning contexts, content, and student characteristics.
  • Detailed Comparative Matrix of Primary Learning Theories:
    • Behaviorism (Pavlov, Thorndike, Skinner):
      • Definition: Learning is defined strictly as the acquisition of new, observable behavior driven by external stimuli, reinforcement, rewards, and punishments.
      • Learner Role: Passive participant responding to external environmental prompts.
      • Main Strategy: Linear stimulus-response chains facilitating the knowing of what.
      • Educational Implication: Objective-based instruction, competency-based education, explicit skill training.
      • Teaching Methods: Direct lectures, simulations, demonstrations, programmed instruction, computer-assisted instruction.
      • Assessment Strategies: Criterion-referenced assessment, standardized multiple-choice questions, direct recall tests.
    • Cognitivism (Piaget, Bruner, Ausubel):
      • Definition: Learning involves the internal acquisition, processing, and reorganization of cognitive structures and mental models.
      • Learner Role: Active participant processing incoming information through intrinsic developmental stages.
      • Main Strategy: Information processing systems facilitating the knowing of how.
      • Educational Implication: Development of concept maps, reflective thinking, structured information framing.
      • Teaching Methods: Problem-solving tasks, concept mapping, advanced organizers.
      • Assessment Strategies: Essay writing, comprehensive written reports, analytic projects.
    • Constructivism (Vygotsky, Dewey):
      • Definition: Learning is an active search for meaning wherein learners construct personal understanding and knowledge through experience.
      • Learner Role: Active creator/constructor of knowledge; teacher serves as facilitator or co-learner.
      • Vygotsky's Social Constructivism: Asserts human cognitive growth is a product of social interactions and cultural context. Directly informs educational games, multimedia development, and dynamic online interactions.
      • Dewey's Experiential Constructivism:
