🎯 Successful Conduct of Classroom Observation 1 (CO1) of Science Teachers S.Y. 2025–2026

The Science Department of Lingunan National High School successfully conducted the Full-Period Classroom Observation 1 (CO1). This activity aimed to support teachers’ professional growth and ensure the effective implementation of the Philippine Professional Standards for Teachers (PPST) in classroom instruction.

Prior to each observation, Sir Jai Eugenio, Department Head, and Ma’am Rowena Lagdamen, Master Teacher, conducted Pre-Observation Conferences with every Science teacher to clarify and review the Classroom Observation Tool (COT) Rubric.

The Classroom Observation 1 was conducted on various dates. Ma’am Joan Mercado had her CO1 on November 24, 2025, followed by Ma’am Rachel Cruzado and Ma’am Gina Mallo on November 26, 2025. The CO1 of Sir Gerald Alzate, Sir Jerome Malamdag, and Sir Genesis Mago was conducted on December 1, 2025, while Ma’am Rowena Lagdamen completed her CO1 on December 4, 2025.

During the observations, the Science teachers effectively demonstrated the CO1 objectives under the PPST. These included showing strong mastery of the lesson and making meaningful connections across learning areas, integrating literacy and numeracy skills within the lesson, and providing critical thinking and higher-order thinking skills (HOTS) activities. Teachers also facilitated meaningful exploration, discovery, and hands-on learning experiences across varied physical learning environments. In addition, they applied differentiated and developmentally appropriate learning experiences responsive to learners’ gender, needs, strengths, interests, and experiences, and planned, managed, and implemented developmentally sequenced teaching and learning processes aligned with curriculum requirements and diverse teaching contexts.

After each observation, a Post-Observation Conference was conducted to present the ratings for each Classroom Observable Indicator and to provide Technical Assistance (TA) aimed at further improving instructional practices.

Congratulations to all the Science teachers of Lingunan NHS for the successful conduct of Classroom Observation 1. Your commitment to quality teaching and continuous professional development truly strengthens our school’s culture of excellence and effective learning. 🌟

SCIENCE DEPARTMENT LAC SESSION | December 5, 2025

The Science Department successfully conducted its Learning Action Cell (LAC) session titled “Reflection on Classroom Observation 1 Teaching Practices and Preparation for Classroom Observation 2.” The session was facilitated by Sir Jai Eugenio, Department Head of Science.

During the activity, teachers openly shared their experiences and reflections on their Classroom Observation 1, highlighting their teaching practices, areas for growth, and best practices that they aim to sustain. In preparation for Classroom Observation 2, the PPST indicators to be observed were discussed to help teachers further improve and align their strategies with professional standards. Teachers also finalized and submitted their schedules for CO2.

A departmental meeting followed, focusing on reclassification to higher teaching positions, where Sir Jai guided the teachers on preparing their Classroom Observable Indicators (COI) and Non-Classroom Observable Indicators (NCOI).

Together, we continue to strive for excellence in teaching and professional growth.

🎉🌟 Happiest Birthday to Sir Gerald Alzate! 🌟🎉

The Science Department successfully conducted a LAC session on PMES Objective 4 entitled "Fostering Active Learning: Managing Classroom Structure for Discovery and Exploration" on November 5, 2025.
With Ma’am Joan Nicole Mercado as the resource speaker, teachers explored strategies for engaging learners through meaningful exploration and collaborative activities. A departmental meeting followed to align observation, curriculum, assessment, and remediation practices.

Science Department Conducts Walkthrough Observations for PMES Phase 2

Last October 21, 2025, the Science Department conducted Walkthrough Observations as part of Phase 2: Performance Monitoring and Coaching in the PMES Cycle, following the guidelines of DepEd Memorandum No. 89, s. 2025. The focus of this non-rated observation was Objective 4: Managing classroom structure to engage learners in meaningful exploration, discovery, and hands-on activities across various learning environments.

The walkthrough was facilitated by Sir Jai Eugenio and Ma’am Rowena Lagdamen. A Debriefing Session was then held on October 22, 2025, where teachers discussed insights, received feedback, and were provided with technical assistance to support their growth.

This initiative aims to prepare our teachers for the Full-Period Classroom Observations and strengthen their continuous professional development, ensuring quality facilitation of learning in our Science classrooms.
