The study aims to develop and validate the usability of the Strategic Intervention
Materials (SIMs) in teaching Elementary English 4 as instructional materials in mastering
Elementary English 4. The study underwent three phases namely: planning, development
and validation. The first stage is planning in which the least learned competencies (LLC)
were identified based on the item analysis of the periodic tests. The researcher made eight
(8) SIMs based on the identified LLC.Second stage is the development in which the
intervention materials were developed based on Vygotsky’s Scaffolding, Keller’s
Personalized System of Instruction, Renner’s Curriculum Model of Instruction based on
Curriculum Development Theory (CDT) of Dewey and Sweller’s Cognitive Load Theory.
After developing the SIMs, the usability experts validated the usability of the materials. The
experts were purposively chosen. They were the master teachers of the intermediate grade
levels who have been teaching English in public schools for five (5) years. The researcher –
made instrument was used in validating the materials. The developed SIMs were rated “very
satisfactory”. This implied that the usability experts considered the SIMs as teacher support
materials that can be used to master the competencies in elementary English 4. The
researcher improved the aspects of the materials that were rated “satisfactory”. It is
recommended that the teachers should develop more strategic intervention materials for
other subject areas to address the pupils’ least learned competencies.
