A key aspect of the CDT framework is that learners can choose their own teaching strategies with regard to content and presentation components. Learning control simply means that the learner can “choose” his or her own learning strategy, either as an individual or as part of a group of learners. [Sources: 0, 13]


Another key aspect of component representation theory is that it allows curriculum planners to give students full control over their own instructions, allowing them to adjust to the number of practical subjects they receive. In other words, e-learning designs based on component representation theory could potentially enable a teacher designer to create a learning experience that allows learners to individualize their learning experience to meet their personal needs and preferences.

Merrill has also developed 18 computer teaching products and is the lead researcher and theorist investigating the potential of automated teaching. Merrill’s research has helped to develop three important theories that underpin today’s discipline of instructional design and technology. The Component Display Theory states that two dimensions can be represented as a matrix and that, depending on the eLearning content, tutorial designers should fill a cell of this matrix with corresponding primary and secondary presentation forms. David Merrill has identified seven assumptions as second-generation design theories. [Sources: 0, 4, 12, 15]


The component representation theory suggests that this combination would provide the best possible result for the design of eLearning content in the form of a matrix.

The other theory is Component Display Theory (CDT), a cognitivistic educational design model introduced by Dave Merrill in the 1980s. This theory was developed by Merrill and Li-Jones and is considered the second generation of instructional design theory. The theory has since been further developed and is understood as the “second generation” of teaching theory. It has also evolved and been considered as a second generation of the “theory of information design.” [Sources: 2, 15]


Merrill revised the original theory of component representation in 1994, but the focus shifted to a macroeconomic perspective. In 1994 he revised it again, this time with the help of his co-author David Li-Jones. Merrill revised its focus to a stronger macro perspective, shifting its focus to the importance of information design in the context of the student’s learning experience and the role of data in educational design and teaching theory. [Sources: 15]


Merrill expanded component representation theory to component design theory, which focuses on individual instruction. This is an attempt to simplify teaching by providing a common basic principle. There is still a prescribed framework for identifying teaching strategies, but more emphasis is placed on simplifying teaching concepts to provide a more holistic view of the student learning experience and the role of data in educational design. [Sources: 1]


The theory of elaboration is one of the most influential theories that influenced the teaching strategies of my Capstone project. The model of curriculum theory derived from this theory is necessary to realize the effectiveness of teaching and learning. Although there is a great overlap between Merrill’s theory and the First Principles of Instruction, we do not find much in common between them. These are the empirical proofs that support their effectiveness, but not necessarily the theory itself. [Sources: 2, 5]
