In a public lecture hosted on Dec. 6, 2023, Prof. David Andrich, Emeritus Professor in the Graduate School of Education and Senior Honorary Research Fellow in the Medical School at the University of Western Australia, shared his extensive insights into the Polytomous Rasch Model for Social Measurement, highlighting its pivotal role and enduring relevance in educational assessment and social research.

Organized by the Center for Educational Assessment (Pusmendik), in collaboration with the Indonesian Educational Evaluation Association (HEPI) and the Universitas Islam Internasional Indonesia (UIII), the event was moderated by Dr. Bambang Sumintono, Head of the Doctoral Program at UIII’s Faculty of Education.

The lecture illuminated the depths of Georg Rasch's work, marking 50 years since Prof. Andrich's scholarly journey began. "It's been a rich 45 years since that seminal 1978 paper, with the implications of Rasch's work for ordered category data continually unfolding," said Prof. Andrich.

Prof. Andrich meticulously outlined the significance of ordered category data within the Rasch Model, emphasizing the need to comprehend its implications thoroughly. "I worked on that for three or four years after my Ph.D. to work out the implications of what Rasch was saying for ordered category data," he said. The dedication to the subject was palpable as he walked the audience through various aspects of the model, from equidistant thresholds to the implications of reverse thresholds.

Moreover, Prof. Andrich highlighted the inherent connection between the Rash Model's ordered thresholds and the concept of randomness in measurement. "The Rash distribution in the model is a discrete form of the normal distribution," he explained. This point is a testament to the model's robustness and seamless integration with traditional measurement principles.

As Prof. Andrich progressed, he underscored the criticality of the model's algebra, which ensures that the comparison between instruments remains independent of the objects of measurement. He noted: "The model is derived from the algebra of this requirement." Prof. Andrich's elucidation of the mathematical underpinnings conveyed a sense of elegance and precision that underlies the Rash Model's framework.

The lecture was a retrospective and a forward-looking reflection on the model's relevance. Prof. Andrich made it clear that understanding the distribution of probabilities within the model is paramount. "This is an example of an item with ten thresholds. These thresholds are not equidistant," Prof. Andrich demonstrated, making the complex concepts accessible to the audience through vivid visualizations and patient explanations.

Another highlight from the lecture was Prof. Andrich’s discussion on the implications of reverse thresholds, a situation where the expected order of threshold values is not maintained, leading to interpretational challenges. "What is the implication of this in this region?" he questioned, pointing to a graph, "If someone happens to be here, this is the distribution." The professor's ability to distill such nuanced details into comprehensible insights was a testament to his expertise.

Prof. David Andrich’s lecture was not merely an academic exercise but a profound exploration of the Rasch Model's foundational principles and their practical applications in educational assessment. His parting wisdom emphasized the necessity for examiners and educators alike to revisit the model's core tenets when faced with data anomalies. The UIII community and its associates were left with much to ponder on the model's capacity to shape educational assessment practices for years to come.

DEPOK, UIII.AC.ID - The Faculty of Education (FoE) at Universitas Islam Internasional Indonesia (UIII) hosted a LUNCHTALK with Dr. Muhammad Adib Abdushomad, Head of the Sub-directorate of Islamic Religious Education at the Senior High School Level within the Directorate of Islamic Education, discussing the relevance of learning organizations and their evaluation at the Ministry of Religious Affairs of Indonesia (MORA).

Dr. Abdushomad emphasized the importance of transforming educational organizations into learning organizations. He highlighted the necessity of continual expansion of capacity, nurturing new patterns of thinking, setting collective aspirations, and fostering an environment of continuous learning.

Dr. Abdushomad advocated for embracing the five disciplines proposed by Senge: system thinking, personal mastery, mental models, shared vision, and team learning. These elements, he argued, are crucial for the personal growth of educators and students alike, reflecting a deep-seated desire for learning and improvement within the organization.

Furthermore, Dr. Abdushomad underscored the influence of mental models and attitudes within an organization. He noted that these models significantly impact the working dynamics and the overall efficacy of an educational system. He also stressed the importance of a shared vision rooted in commitment and values, arguing that this is essential for the successful operation of an organization like MORA.

The concept of team learning, as presented by Dr. Abdushomad, involves aligning and developing the capacity of a team to achieve its collective goals. This builds on the development of a shared vision and personal mastery, bringing together talented individuals for collective success. Additionally, Dr. Abdushomad touched upon the importance of system thinking, emphasizing the need to understand the interrelationships among key system components while acknowledging the human factor as a critical asset.

In addition, Dr. Abdushomad delved into the current challenges and strategies in knowledge management at MORA. He critiqued the tendency to view knowledge as a product rather than a process, calling for a shift towards a process strategy. This strategy, he suggested, should involve facilitating conversation and exchange of tacit knowledge, hiring qualified personnel capable of tolerating ambiguity and sharing knowledge, and encouraging one-on-one mentoring.

At the end of his lecture, Dr. Abdushomad called for a change in strategy from a product-centric approach to one focused on processes. He urged the need for spaces that enable more effective and efficient knowledge sharing. He also highlighted the need for leaders for change at MORA who can adapt to new ways of working and respond with flexibility and learning-oriented leadership.

Dr. Muhammad Adib Abdushomad’s insights offer a compelling vision for the future of Islamic education. His emphasis on learning organizations, personal mastery, and collective learning aligns with the global shift towards more dynamic, responsive, and collaborative educational models. His call for change and adaptive leadership resonates with the current needs of educational institutions worldwide, particularly in the context of Islamic education, where traditional methods are being reevaluated in light of contemporary challenges and opportunities.
