My doctoral dissertation was specifically focused on preparation, validation and testing the effectiveness of the Strategic Intervention Materials (SIM) in teaching Science IV (Physics). The SIMs prepared were tested in the two sections of a fourth year class for two grading periods. The twelve (12) Strategic Interventions Materials (SIM) prepared are given below as what they appeared and compiled and bookbounded. Each SIM will be posted here. These are all taken from my unpublished doctoral dissertation book, 2007.
INTRODUCTION
“Rich countries are science-rich and poor countries are science-poor”. This statement was made by Dr. Frank Tui, the companion of Senator Emmanuel Pelaez, the “father” of Science Act of 1958.
Physics is one of the main fields of Science. Physics as a subject in the secondary Basic Education Curriculum is concerned with the basic laws of nature. It deals with the study of matter and energy and their relationship.
Physics is concerned on the physical science around which the other sciences are founded. Its full and complete understanding is important to the comprehension of the natural sciences such as astronomy, geology, and meteorology. Similarly with chemistry which uses modern atomic theory to predict structures of atoms and interaction between atoms. Living things are composed of matter and transform energy, and therefore, biology must consider this phase of Physics.
In the study of this subject, it calls for active participation of the students in learning the concepts and principles of Physics. The inductive techniques through hands-on activities lead to a deeper understanding of Physics.
The manner by which the topics are presented follows the latest list of learning competencies published and disseminated by the Department of Education (DepEd).Hence, the topics cover the Energy in the Environment on Unit II found in the Science IV (Physics) textbook, from the Behavior of Light down to the Diffraction Property of Light.
One of the purposes of this developed Strategic Intervention Materials (SIM) is to persuade students that Physics is fundamentally a collection of just a few concepts, but very powerful concepts that bring insight and understanding toa surprisingly large array of phenomena.
It is expected that the discussion of any of the topics using the Strategic Intervention Materials (SIM) or in any science lessons, the greater emphasis is on developing the science process skills, the acquisition of values and habits of the mind that make the student a better problem solver and an efficient decision maker.
RATIONALE
Students are the focus in an educative process. Teaching-learning situations provided to the students are as important as the students in the classroom. It is a recognized fact that every classroom encounter is a product of significant factors of the learning environment such as the ability of the pupils, background information previously learned, availability of instructional materials, and other facilities in the science room.
Science teaching is more productive when there available and sufficient instructional materials. However, with the present situation of Philippine educational system wherein there are shortages in the classrooms throughout the country. Thus, funds are not enough to cater to the needs on instructional materials needed in every science classroom. The science teacher therefore, is responsible to devise and provide the necessary materials for use in science classes.
Science IV (Physics) is one among the science subjects in the secondary curriculum where there is a dearth of instructional resources like books and supplementary reading materials like science magazines, etc. Hence, the Strategic Intervention Materials (SIM) in Science IV (Physics) developed by the researcher-writercan be a response to the inadequacy of books and related materials in the said subject.
OBJECTIVES
The Strategic Intervention Materials (SIM) aim to provide the students with a learning experience which could give them the opportunities to harness their scientific skills and values through a simpler way of understanding the contents of the subject. Categorically, the objectives of the entire set of Strategic Intervention Materials (SIM) are:
1.Investigate the reflection and refraction properties of light using simple optical devices (e.g. plane mirror, curved mirror [convex and concave] and lenses [convex and concave]).
2.Describe images formed by plan mirror, curved mirror (convex and concave) and lenses (concave and convex) experimentally.
3.Locate and describe images formed by plane mirror, curved mirror (convex and concave) and lenses (convex and concave) through ray diagrams.
4.Locate and describe images formed by curved mirror (convex and concave) and lenses (convex and concave) using mirror equation.
5.Explain the different eyesight defects and how lenses correct these defects.
6.Demonstrate total internal reflection, interference, diffraction, and polarization properties of light.
7.Explain and cite applications of total internal reflection, interference, diffraction, and polarization properties of light.
STRATEGIC INTERVENTION MATERIALS (SIM) IN SCIENCE IV (PHYSICS)
The organization of the Strategic Intervention Materials (SIM) was:
SIM 1 - Behavior of Light (All About Light)
SIM 2 - Image Formation in Plane Mirror (How Do I Look?)
SIM 3 - Image Formation in Curved Mirror (All About Images)
SIM 4 -Mirror Equation (Solve Me and Make Me Bigger)
SIM 5 - Refraction of Light: Snell’s Law (Bend to the Right,Bend to the Left!)
SIM 6 -Total Internal Reflection of Light (Don’t Get Trapped)
SIM 7 -Image Formation in Lenses (Is It Bigger of Smaller?)
SIM 8 - Lens Equation (Is It Up Side Down?)
SIM 9 - Vision Defects (Are You Myopic or Hyperopic?)
SIM 10 - Interference of Light (Stripes of Light)
SIM 11 - Diffraction of Light (The Bent Edges)
SIM 12 - Polarization of Light (The Glow Around Me)
