Research on Cognitive Load Theory: Application to E-Learning
- The purpose of this article is to review and critique each of the research studies published in this special issue.
- In the traditional, face-to-face classroom, instructional designers tend to rely on the instructor or the students’ peers to make needed adaptations and support if a student fails to understand an idea.
- The authors wish to caution the reader that these heuristics are based on the studies presented in this special issue rather than on multiple studies.
TRACEY CLARKE, PAUL AYRES, AND JOHN SWELLER
- In many cases it is assumed that using technology will enhance learning efficacy by improving both the efficiency and effectiveness of the learning experience.
- In e-learning environments, students are expected to learn how to use delivery technology such as Blackboard and WebCt, including skills such as chatting online, participating in threaded discussions, and posting assignments.
- In many cases learning about the delivery technology takes place concurrently with the learning of content and accomplishment of primary content goals.
- Two sequencing strategies, (a) learning spreadsheet skills and then mathematical concepts in sequence, and (b) learning spreadsheet skills and mathematics concepts concurrently were included.
- A subjective measure of cognitive load was also administered.
Future Research Recommendations
- Kalyuga and Sweller indicated that a less intrusive measure is needed in an e-learning environment.
- This measure would be useful for not only adaptive instructional research, but also other cognitive load studies.
- Studies such as Kalyuga and Sweller’s, that extend cognitive load research beyond message design into the area of instructional strategy design, provide an important and interesting approach to the design of instruction.
A. AUBTEEN DARABI
- Studies with external validity are of particular interest to the instructional designer (Ross & Morrison, 1989).
- Typically, these studies use realistic materials and employ realistic environments as opposed to the highly controlled environments of a basic research study.
- They suggest that motivation may be a critical factor in the design of instructional materials that engage the learner and enhance the learner’s effort.
- Designers are constantly faced with finding an optimum balance between easy and difficult materials that will challenge the learner while trying to avoid frustration or materials so easy that the learner’s effort results in only meager gains.
1. Exploratory practice results in greater involvement than do worked examples for experienced students.
- Problem-based learning (PBL) and worked examples provide two contrasting approaches to instructional design.
- PBL can provide a rich, realistic context that allows the learner to explore various options, whereas worked examples provide a guided approach.
- This heuristic suggests that students with no prior knowledge might benefit first from worked examples, then move to a PBL environment to increase their involvement and mental effort.
2. Students with no prior knowledge will have less efficiency with exploration practice than with worked examples.
- The efficiency of such practice may be an issue when there is limited time for the training.
- If an exploratory strategy is needed or more appropriate, students with no prior knowledge might first start with worked examples before using the exploratory examples.
ROXANA MORENO AND FRED VALDEZ
- It is clear that learners are required to process many external representations during their elearning experiences.
- Investigations examining the impact of multiple representations on learning and cognitive processing are warranted (Anglin, Vaez, & Cunningham, 2004).
- Incorporating Mayer and Moreno’s (2003) cognitive theory of multimedia learning (CTML), Moreno and Valdez examined the effect of interactivity and feedback when learning from either single or multiple ( and pictures) external representations in the area of meteorology.
- Retention and problem solving were assessed and cognitive load was measured using a subjective measure.
WOLFGANG SCHNOTZ AND THORSTEN RASCH
- Results of studies examining the effect of animations on learning have been mixed.
- Schnotz and Rasch investigated the effect of two types of animations on knowledge acquisition.
- Schnotz and Rasch also distinguished between learners with high and low learning prerequisites.
- They did not directly measure cognitive load.
- The authors have identified one heuristic in this study; however, a number of the effects identified by Schnotz and Rasch were reported as marginally significant.
ERIK WALLEN, JAN L. PLASS, AND ROLAND BRÜNKEN
- Managing cognitive load is a critical issue when designing e-learning.
- If the combination of intrinsic and extraneous load is too great, the learner will not develop an understanding of the instructional content as intended.
- The individualized nature and separation of the learner from other learners and the instructor in e-learning places a greater responsibility for developing an understanding on the individual learner than in the traditional face-to-face classroom.
- The article by Wallen, Plass, and Brünken investigated the use of text annotations to support the develop- ment of schemas.
- Three strategies, using (a) selection, (b) organization, and (c) integration were tested individually and in pairs to determine their effectiveness for enhancing learning.
1. Adding verbal annotations to text can improve recall and transfer performance.
- Providing learners with definitions of terms with contextual information (selection level), brief explanations of an idea in the specific context (organization level), or by showing links of ideas in a paragraph (integration level) can enhance recall of terms and ideas.
- Integrating one of these strategies does not appear to increase extraneous cognitive load significantly, but rather, it may enhance germane cognitive load.
- This strategy is potentially useful as a means of providing additional instructional support for the e-learning student.
2. Selection and organization-level annotations can enhance comprehension.
- When the recall of idea units rather than words is the goal, learner performance is enhanced with the use of selection and organization-level annotations.
- Thus, providing definitions and explanations as an adjunct to the text can enhance recall of idea units.
3. Providing more than one type of annotation results in a decrease in performance.
- When using annotations to enhance learning, increasing the types of annotation results in a degrading effect.
- That is, using both selection and organization-level annotation results in a lower performance than using only selection or organization-level annotation.
- The additional annotation increases the amount of text a learner must process and may result in an increase in extraneous cognitive load.
- This increase in cognitive load may exceed the learner’s capacity and result in the failure to develop an adequate schema for the material.
1. Designing deliberate practice strategies to enhance germane cognitive load can lead to the development of expertise.
- Mindful design of learner-appropriate, deliberate practice that includes feedback to encourage learners to reflect on their errors may enhance germane cognitive load.
- Strategies can incorporate reflection, and other elaboration strategies can enhance learning from errors.
2. The effectiveness of deliberate practice is enhanced if the learner is motivated.
- Learners must not only be motivated to engage in the practice, they must also be engaged in a mindful way so that they can make effective use of the feedback to correct errors and develop appropriate schemas.
- Research on feedback has found that learners who are motivated in a realistic setting will make more mindful use of feedback than students who are simply participating in an experiment (Morrison, Ross, Gopalakrishnan, & Casey, 1995).
- Instructional designers need to devise an instructional strategy that is not only engaging, but is also motivating.
SLAVA KALYUGA AND JOHN SWELLER
- The use of adaptive models using various algorithms and approaches has a rich history of research in the field of instructional technology (Ross, 1984; Ross & Rakow, 1982; Tennyson & Buttery, 1980; Tennyson & Rothen, 1979).
- Kalyuga and Sweller have extended this research by using cognitive load as an adapting variable.
- By using a rapid measure of semantic knowledge and a subjective cognitive load measure, they calculated cognitive efficiency to adapt instruction to each learner.
- Combining these two measures allows the designer to adapt the instruction for the next step as well as the level of difficulty.
1. Making adaptive decisions based on performance and a subjective measure of cognitive load may result in more efficient learning.
- This heuristic provides an alternative to designing one form of instruction and relying on time as the individualization factor.
- To implement this approach, designers would need to have instruction written for at least two levels of difficulty and implement a rapid assessment approach.
- The participants in the study were 10th-grade students who participated in frequent testing as part of the learning process.
- Adults who are not as accustomed to frequent testing may not be as successful or willing to learn using this approach.
SUMMARY
- Early research based on cognitive load theory attempted to identify methods of reducing extraneous cognitive load (Sweller et al., 1998).
- Germane cognitive load, and perquisite skills.the authors.
- More research needs to be completed to provide a sound research base for their heuristics.
- Thus, researchers should consider conducting applied studies that sacrifice some internal validity at the expense of higher external validity.

Q2. What are the future works mentioned in the paper "Research on cognitive load theory: application to e-learning" ?
Future research on sequencing strategies ( sequential and concurrent ), including technology and mathematics content with high element interactivity, is needed. Although self-assessment is a useful research tool, the authors recommend for future research that cognitive load and spreadsheet skills be directly assessed or measured. Finally, future studies extending the work of Clarke et al. should be conducted with students actually enrolled in e-learning courses. The authors agree with Paas et al. that future research considering cognitive load theory and motivation should focus on realistic environments.
Q3. What areas of study should be considered in future studies?
Future studies should consider less-structure areas such as interpersonal and management skills, where researchers might vary the complexity and difficulty of cases or examples to teach a concept or rule.
Q4. What is the role of the instructor in e-learning?
The individualized nature and separation of the learner from other learners and the instructor in e-learning places a greater responsibility for developing an understanding on the individual learner than in the traditional face-to-face classroom.
Q5. What is the way to improve transfer learning?
2. Strategies for interactivity that involve the learner in the process of understanding (schema development) prior to feedback will enhance transfer learning.
Q6. What are the key variables when determining the sequencing strategy?
The learner’s level of technology skills, and the level of content element interactivity are critical variables when determining the sequencing strategy (Kalyuga et al., 2003; van Merriënboer, Kirschner, & Kester, 2003).
Q7. What is the heuristic for the Moreno and Valdez study?
Their heuristic is developed assuming that designers would use the specific types of interactivity (organize causal chain of events) and feedback (frame-byframe) included in the Moreno and Valdez study.
Q8. What is the effect of the cognitive theory of multimedia learning?
Incorporating Mayer and Moreno’s (2003) cognitive theory of multimedia learning (CTML), Moreno and Valdez examined the effect of interactivity and feedback when learning from either single (words) or multiple (words and pictures) external representations in the area of meteorology.
