YOGYAKARTA – The Indonesian Center for Cognitive Load Research (ICCLR) successfully hosted a Guest Lecturer session featuring education expert from the University of Sydney, Assoc. Prof. Paul Ginns, Ph.D. Focusing on the theme “Instructional Design and Research on Cognitive Load Theory,” the academic event was enthusiastically attended at Meeting Room 2, 4th Floor, Master’s and Doctoral Building, FMIPA UNY, on Tuesday, 4 August 2026.

The event was attended by lecturers and students from the Bachelor’s, Master’s, and Doctoral programs in Mathematics Education. The program was comprehensively structured into two lecture sessions. The first session, held from 09:00 to 12:00 WIB, explored the topic “An Introduction to Cognitive Load Theory and Load Reduction Instruction.” The program continued with a second session from 13:00 to 14:30 WIB, focusing on the methodological aspects of “Educational Research Using Experiments.”

In the first session, Paul Ginns provided an in-depth discussion of human cognitive architecture, particularly highlighting the crucial relationship between long-term memory, which serves as the repository of knowledge schemas, and working memory, whose capacity is highly limited.

To demonstrate the limitations of working memory, participants were invited to take part in an interactive quiz involving a digit span task. They were challenged to listen to and repeat sequences of numbers spoken by the presenter. At the beginning, participants could reproduce the sequences relatively easily. However, as the number of digits increased, many participants began to experience difficulty recalling the sequences accurately.

Building on an understanding of cognitive architecture, he introduced several key strategies for educators to optimize instructional design. These strategies include:

• Adapting lessons to students’ prior levels of knowledge and skills.
• Using worked examples to teach new content or skills.
• Gradually increasing opportunities for independent problem-solving as students become more proficient.
• Removing inessential information to minimize unnecessary distractions.
• Integrating all essential information and using attention-guiding signals to direct students’ attention.
• Recognizing that auditory information is transient and therefore needs to be presented at an appropriate pace.

These principles culminate in the Load Reduction Instruction (LRI) approach. The LRI framework consists of five interconnected elements that combine explicit instruction with the gradual development of learner independence: Difficulty Reduction, Support and Scaffolding, Practice, Feedback-Feedforward, and Independence.

Moving into the second session in the afternoon, the lecture shifted its focus to the application of experiments in educational research. Paul Ginns emphasized that credible scientifically based research must be grounded in the development of logical, evidence-based chains of reasoning.

He further explained that research validity requires the use of methods that are genuinely aligned with the research questions being investigated. This must be supported by the selection of appropriate experimental designs and instruments to produce reliable and generalizable findings. Ultimately, empirical data collection and robust statistical analysis are essential to substantiate and support the findings generated through experimental research.

The participation of an international expert through the Guest Lecturer program further demonstrates ICCLR’s commitment to fostering academic discourse and disseminating knowledge at a global standard. By integrating a strong understanding of cognitive architecture with rigorous research methodology, academics and students are expected to produce more robust and impactful educational research that can be effectively implemented to contribute to the advancement of education in Indonesia.
