Developing a Blended Learning Strategy: Instructional Media and Pedagogical Considerations Dr. Jolly Holden Chairman Emeritus, United States Distance Learning Association
The Challenge Driven by the demand to increase access to learning opportunities, educators and trainers are continually challenged to develop and integrate instructional delivery options and reduce costs without impacting instructional integrity, which leads to this question: Q: How do you meet the demand and reduce costs and/or output without sacrificing instructional quality? A: The development and implementation of a blended learning strategy.
The Trainer’s Rules of Engagement Blended learning allows the instructional designer the opportunity to leverage the strengths of instructional media with the efficacy of the instructional components to ensure the instructional goal is attained. However, to ensure a successful blended learning strategy, it is imperative you conduct a thorough media analysis while addressing the applicable components of the instructional systems design process. “Migrating to blended learning formats requires instructional design analysis that integrates with the technologies that will be utilized to deliver it.” The e-Learning Developers Journal, June, 2005

DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications Blended Learning Definition A Holistic Perspective The delivery of instruction using multiple media* Includes the integration of instructional media into a traditional classroom or into a distance learning environment. Includes any combination of media that supports instruction, regardless of the mix of synchronous or asynchronous media. * Source: Distance Learning Magazine, Vol 3, Number 2, 2006, Instructional Media Selection for Distance Learning: A Learning Environment Approach There is no universally accepted definition of blended learning. The following pages articulate several definitions representing different perspectives in an attempt to define this term, but they all have one essential component in common...an integration of instructional media. A rose by any other name is still a rose... A combination of synchronous and asynchronous experiences. For clarification, blended learning is also applied to mixed online and face-to-face training, and more generally to approaches to course design and delivery that combine different modalities (e.g., self-paced Web-based training, followed by classroom instruction, accompanied by printed job aids, and supplemented by virtual classroom follow-up sessions).

DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications Note According to a recent report (March 2007) by the Sloan-C Foundation entitled Blending In The Extent and Promise of Blended Education in the United States*, only 38% of surveyed universities agreed that “blended courses hold more promise than online courses” in 2004, a decrease from 46 percent agreement in 2003. Note: The percentage of reported blended course offerings remained stable from 2002–2005 while the percentage offered online increased. Schools report offering an average of 10.6 percent of their course sections online in 2005, up from 6.5 percent in 2003, while the respective percentages for blended offerings shown a steady decline from 2003 (6.8%) to 2005 (5.6%) Click for Comment Comment: In online learning for higher education, the majority of instructional content resides in printed material, i.e., the course text(s) [aka the Binded Object Oriented Knowledge System--BOOKS], delivered via mail and not online.

DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications Where [and when] it really Started “I do not know any innovation upon existing methods more radical and revolutionary than this” Although thisquotesounds as if it were referring to a new technological break- through, in reality, this profound statement was uttered by the Reverend Joseph H. Odell, D. D. (1910) in his address titled "The New Era in Education: A Study of the Psychology of Correspondence Methods of Instruction" delivered in 1910 at the dedication of the instruction building of the International Correspondence Schools in Scranton, Pennsylvania. Nearly a century later, similar sentiments are still echoed today Blended learning is “…the single greatest unrecognized trend in higher education.” J. Young, President, Pennsylvania State University, 2002
DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications Evolution of Instructional Media What does it mean? As instructional media continues to evolve, propelled by advances in technology and fueled by the need to increase learning opportunities, the evolution and advancements of instructional media will continue to accelerate as well. As a result, permutations of the basic concept will also emerge, resulting in different applications of blended learning and further variations of the definition. Consequently, by tracing the history and genealogy of instructional media, one can establish a solid foundation by which to better understand and apply the basic constructs of blended learning. Developing a comprehensive blended learning strategy is more than just integrating instructional media. It’s about considering all aspects of the learning event in attaining the ultimate goal: Increasing performance. So let’s begin the journey…

This timeline traces the genealogy of instructional media by depicting its early origins over 120 years ago to the application of modern communication media to meet today’s demands. As the country grew and evolved from an agrarian society to an industrialized nation, the demand for education increased significantly. With the ensuing emergence of radio and TV, the education community quickly realized the potential of these new media and adopted them to distribute education programs to a geographically dispersed workforce. Chautauqua [Correspondence] Institute founded in NY Then, with the introduction of the computer, learning communities quickly realized the potential of this powerful new technology and adopted it as another delivery tool. As the computer continued to evolve, a new generation of the computer-mediated instruction arrived, culminating in the emergence of the Internet.

DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications The Basics The Learning Environment: Two Dimensions Synchronous Asynchronous • Same time/same place • (traditional instructor-led classroom) • Same time/different place • (virtual instructor-led classroom) • Different time/different place So how are these two environments integrated as it applies to blended learning? Click the next arrow for more on synchronicity.
DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications The Concept of Synchronicity Although synchronicity is dichotomous, per se, either synchronous or asynchronous, it does not mean they are mutually exclusive when considering a blended learning solution. If viewed as being on opposite ends of a continuum, the degree to which these two dichotomous environments can be integrated would result in a blending of synchronicity. Synchronous Asynchronous Blended Learning Therefore, to attain the most optimum blend, one must consider the vehicle(s) that deliver the content, the [learning environment] in which the learning occurs, and the instructional objective(s) [which drive the development of the content and instructional strategies]. Consequently, blended learning can include any combination of media that supports instruction, regardless of the mix of synchronous or asynchronous media.

Therefore, a blended learning model can be used as a guide in evaluating and integrating separate components that would result in an instructionally sound learning situation. The second component is to determine which learning environment (synchronous/ asynchronous) best supports the instructional objectives “Collaborative online learning is now recognized as a component of a mature blended-learning strategy.” Bersin & Associates, Technology Update: Open Source e-Learning Systems, June 2007 The third component is to select the instructional strategies that support the learning objectives The first component is used to evaluate the most appropriate media to delivery the content

For a brief summary of each component, click here. The degree of integration is based upon evaluating each component's specific attributes, resulting in the most appropriate blend to ensure attainment of the overall instructional goal. With that said and bearing in mind this model is based upon a set of related components, that although evaluated separately, are also viewed holistically. That is to say, each component’s specific contribution must be viewed as it relates to the sum total of all the parts…which results in a comprehensive blended learning solution.

Learning Environment Instructional Media DefinitionsMedia EvolutionLearning EnvironmentsBlended Learning ModelElasticityImplications The Concept of Elasticity in Blended Learning elasticity The power of blended learning is in its The point is this…there may be several “blended” solutions that can meet your instructional objectives, so consider the qualitative merits of all instructional media. The ultimate goal is to increase performance through the systematic evaluation of intra-dependent variables that would result in the most appropriate integration of media. Depending upon the [cognitive] level of the learning objectives and the learning environment (synchronous vis-a-vis asynchronous), different combinations of instructional media and instructional strategies can support various levels of interactivity to attain the most appropriate "blend". As the blend changes, the model becomes "elastic", allowing the instructional designer to modify the “blend” to meet specific learning outcomes. Learning Environment Learning Environment Instructional Instructional Media Any combination of instructional delivery medium, including the traditional classroom, can result in a blended learning solution, but the instructional efficacy of the solution is most dependent upon the instructional and learning environment components.

Learning Environment Component Asynchronous A learning environment can either be synchronous or asynchronous, per se, the learning is either occurring real-time with an instructor (synchronous), or it is occurring without the presence of an instructor (asynchronous). Regardless, each learning environment has their distinct advantages and disadvantages, and the goal of developing a blended learning strategy is to leverage those specific attributes of each environment to ensure the most optimum use of resources to attain the instructional goal.

Media Component Some instructional media may be more appropriate than others in supporting either a synchronous or asynchronous learning environment, but no single medium is inherently better or worse than another. Although the delivery medium does not affect the content, the selection of certain media may affect how you design the content based on the attributes of that specific medium. Regardless, when the “most appropriate” media are selected based on the ISD process, then learning outcomes will not be affected. Media are vehicles that simply deliver their contents. When developing a blended learning solution, the selection of the most appropriate media is not based solelyon the attributes for that specific medium, but how the media may also impact the pedagogical components, e.g., the learning environment and instructional components.

Synchronous Instructional Media Technology Delivery Description Audio Conferencing An audio-only environment in which students in different locations use telephones or audio conferencing equipment to communicate with each other in real time. Supports a synchronous interactive environment between the instructor, remote students, and multiple sites but does not support visual images and graphics, and often supplemented by electronic or printed handouts. Can be integrated with other delivery systems to provide synchronous audio. Audiographics combines audio conferencing with personal computer text and graphics, allowing both voice and data to be transmitted to remote sites. Typically, a site consists of audio conference equipment, plus a large screen that serves as an electronic whiteboard. This system allows for two-way data exchange (limited to high-resolution still images only) and a synchronous interactive environment between the instructor and students at multiple sites. Audiographics Synchronous Web-Based Instruction (WBI)/Web Conferencing (Synchronous Learning Systems) Internet-based and delivered over the Web that enable synchronous audio and/or text chat, video, document and application sharing, whiteboards, presentations, etc. Can support synchronous oral interaction between the instructor and remote students at multiple locations as well as supporting Multi-User Virtual Environment (MUVE) or webinars. Due to bandwidth limitations (basically, low-bandwidth applications), high-resolution images and video may be limited. Note: The application of web conferencing in a learning environment is also known as synchronous learning systems (SLS). Instructional Television (ITV) ITV is defined as a one-way, full motion video and audio transmission of classroom instruction through a telecommunications channel such as satellite, cable TV, or Instructional TV Fixed Service (ITFS), a dedicated 2.5GHz spectrum managed by the FCC and limited to educational programming only, usually transmitted via microwave
Technology Delivery Description Instructional Television (ITV)- con’t towers. This specific application would not be available to instructional programming programming received via commercial cable TV). Due to the bandwidth available via satellite or ITFS, this delivery medium can emulate the live, traditional classroom environment but at a distance. ITV is sometimes referred to as Business Television (BTV), Interactive Video Teletraining, or Interactive TV, and can be transmitted via analog or digital systems. Satellite e-learning Satellite e-learning represents the next generation of distributed media. Utilizing IP (Internet Protocol) as the network layer and distribution technology, it also incorporates the latest MPEG (Moving Picture Experts Group) video standard or latest version of Widows Media. Similar in application to ITV, it allows for the live traditional classroom to be transmitted to a remote site while synchronous oral interactivity is supported by audio teleconferencing or student response systems integrating audio and keypad technology (data interaction). Additionally, since satellite e-learning uses IP, video streaming can be utilized at extremely high bandwidths (~3.0Mbps). The IP-based video can be distributed directly to the user’s end-point and then distributed via the LAN to either a classroom or desktop computer, or both. Also, satellite e-learning can easily transmit large multimedia/web-based training modules (known as data casting) without being constrained by bandwidth, as is common with a terrestrial network. This capability allows the data to bypass the WAN by transmitting directly to the user’s end-point and then distributed locally via the LAN, thereby effectively bypassing the terrestrial infrastructure and the Internet. Satellite e-learning is also referred to as BTV/IP (Business Television/Internet Protocol). Synchronous Instructional Media

Refers to how portable (mobile) a specific media may be, e.g., cell phones, ipods, personal DVD players, other similar wireless devices. When evaluating portability, consider symmetry, per se,the amount of information [digital bits] that flows to/from the sender and receiver in either direction. For example: Asymmetrical interaction is when the flow of information is predominantly in a single direction such as in a didactic lecture or computer based instruction with little or no interaction between the student and instructor. Most consumer internet services are asymmetrical in that the majority of digital information is only flowing one direction for downloading. Conversely, in a conferencing or collaborative learning environment, the information flow is symmetrical; that is to say, the information flow is evenly distributed between learners and instructors and equal amounts of digital information is flowing both directions. A close relationship exists between symmetry and interactivity. The more the interaction, the greater the need for a symmetrical delivery system.

Symmetrical vs. Asymmetrical Learning Environments When articulating a blended learning strategy, considering symmetry of the learning environment is almost as important as considering its synchronicity.

The most significant factors in student learning are quality and effectiveness of instruction, and the most important single factor in developing a blended learning solution is the instructional objective. The level of cognitive objectives is a critical variable to consider when selecting the most appropriate media for blended learning, and generally speaking: Note on Learning Objectives • Asynchronous media may be more appropriate for the lower cognitive levels where knowledge and comprehension and repetition/drill & practice are the primary focus, and • Synchronous media may be more appropriate for the higher cognitive levels (synthesis/analysis/evaluation) where a synchronous learning environment is required to support a high level of interaction (dialog).
