The DOST Courseware is a locally-produced, all-original Filipino highly interactive multimedia educational application packages that are conceptualized, digitized and produced as spearheaded by the Science Education Institute (SEI-DOST) in partnership with the Advanced Science and Technology Institute (ASTI-DOST) and in cooperation with the Department of Education (DepEd), Philippine Normal University (PNU) and University of the Philippines-National Institute for Science and Mathematics Education (UP-NISMED), which aims to develop information and communication technology learning innovation to support the upgrading and improvement of science and mathematics education in the country. The DOST Courseware are provided for free to schools and are also made available online as supplemental resources for teachers and student as a fun and interactive approach to e-learning and blended learning. The Grade 7 DOST Courseware is composed of 120 lessons overall, 73 lessons in Science where it covered the domains on: Matter; Force, Motion and Energy, Living Things and Their Environment and Earth and Space while the 60 lessons in Mathematic covered the domains on: Numbers and Number Sense, Patterns and Algebra, and Geometry. The Grade 8 DOST Courseware is composed of 118 lessons overall, 61 lessons in Science where it covered the domains on: Parts and Functions, Ecosystems, Heredity: Inheritance and Variation of Traits, Structures and Functions, Biodiversity, and Evolution, while the 57 lessons in Mathematics covered the domains on: Linear Equations, Quadratic Equations, Rational Algebraic Equations, Integral Exponents, Radicals, Arithmetic Sequence and Geometric Sequence. The themes of the courseware for Grades 7 and 8, Magicademy, Freddy’s Lab and D’nayao will surely amuse the users as they explore these distinct worlds while learning at the same time.

Irrigation Engineering Practice is an educational application designed to help students understand and practice the principles of irrigation systems, water resources development, and agricultural water management. The app emphasizes structured learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard irrigation engineering curricula. Users can practice questions from individual topics, attempt mock tests for comprehensive assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and examination preparation for civil engineering students. Topics Included 1. Introduction to Irrigation Irrigation engineering concepts, need and advantages of irrigation, types of irrigation, sources of irrigation water, and water resources development. 2. Soil Water Plant Relationship Soil water concepts, field capacity, wilting point, available water, root zone depth, and consumptive use. 3. Irrigation Water Requirement Crop water requirement, duty of water, delta, base period, irrigation efficiency, and water losses. 4. Canal Irrigation Types of canals, canal alignment, canal cross-section, canal lining, and maintenance. 5. Canal Design and Regulation Kennedy’s and Lacey’s theories, discharge measurement, canal falls, cross regulators, and escapes. 6. Diversion Headworks Weirs, barrages, divide walls, fish ladders, and under sluices. 7. Storage Structures Types of dams, spillways, reservoir capacity, forces on dams, and dam safety. 8.
