Each invited speaker delivers a scientific presentation in a separate parallel session, allowing participants to choose the topic most relevant to their interests and areas of expertise.

In the parallel session, participants who serve as presenters will deliver presentations based on their submitted articles. This session is conducted in a hybrid format. Participants attending online will present their articles via Zoom meetings provided by the organizing committee. Presenters are required to present their articles using a PowerPoint (PPT) presentation of no more than 10 slides, covering the full content of their article. For on-site participants, presentations will take place in designated rooms grouped by the committee. The committee will organize presenters into groups based on their background—lecturers, teachers, and students—with each group facilitated by a moderator appointed by the committee. Presenters who wish to publish their articles may choose from a selection of nationally accredited journals (SINTA) that are in collaboration with this conference. Those who opt to publish in an accredited SINTA journal will be subject to an additional publication fee, the amount of which will correspond to the publication cost of the chosen journal.

The school visit is part of the series of activities in the ICLS. Conference participants who register for this activity will visit SDN 037 Pekanbaru and SMPN 23 Pekanbaru, two partner schools of the Faculty of Teacher Training and Education, Universitas Riau, that have successfully implemented lesson study in a sustainable manner within their teaching and learning processes. Through this visit, participants will gain firsthand insights into the practice of lesson study at both elementary and secondary school levels, covering the full cycle of planning, implementation, and reflection with teachers (plan-do-see). This activity aims to broaden participants’ understanding of lesson study implementation in real classroom settings and to encourage its replication in other schools.

This workshop is one of the key activities in the 16th ICLS, designed to engage both in-service teachers and pre-service teachers. The session provides hands-on training and collaborative discussions focused on the principles and practices of Lesson Study. Participants explore strategies for planning, observing, and reflecting on classroom instruction, with the goal of enhancing teaching quality and student learning. The workshop aims to build professional capacity, foster learning communities, and promote sustainable implementation of Lesson Study in schools and teacher education programs.
