Study Notes

  • Pre-service teachers will understand the basis for offering Genetics in the BSEd Science Course and discuss the subject's relevance to Science Education within the K-12 curriculum.

Basis for Genetics Subject

  • The Commission on Higher Education (CHED) Memorandum Order or CMO No. 75, s. 2017, which outlines the Policy, Standards, and Guidelines for Bachelor of Secondary Education, is the basis for offering Genetics to Science Education students.
  • The CMO serves as a guide for curriculum planners and educators regarding the content of the lecture and laboratory components.
  • The lecture part of the subject introduces pre-service science teachers to various topics:
    • Cellular reproduction
    • Introduction to genetics
    • Mendelian genetics
    • Non-Mendelian patterns of inheritance
    • Sex determination
    • Pedigree analysis
    • DNA structure, replication, transcription, and translation
    • Chromosomal aberrations
  • Pre-service teachers will gain an overview of heredity and variation, its application to plant and animal breeding, and related problems, including the biometrical treatment of qualitative and quantitative characters in plants and animals.
  • The laboratory part of the course focuses on exercises related to the chromosomal basis of inheritance, the structure of genetic material, and Mendelian and non-Mendelian inheritance.

Science in K-12 Curriculum

  • The topics are rudimentary for teaching science at the secondary level of the K-12 curriculum.
  • Learning activities and assessment methods require research data presentation and the utilization of ICT for student group-facilitated class demonstrations and discussions.
  • Genetics is defined as the study of heredity and variation, including the patterns of inheritance of specific traits related to genes and genetic information.

Relevance to BSEd Science Students

  • The subject provides learners with the knowledge and skills necessary to teach related subjects in Junior and Senior High School.
  • Genetics topics are integrated across various year levels in the K-12 Curriculum, including:
    • Elementary Science
    • Junior High School Science
    • Senior High School Curricula (both STEM and non-STEM strands).
  • Grade 3: Students learn that living things reproduce, and traits are passed on to offspring.
  • Grade 4: Students learn about the life cycles of humans, animals, and plants, and how inherited traits can be influenced by the environment.
  • Grade 5: Students learn how flowering and non-flowering plants reproduce and are introduced to sexual and asexual modes of reproduction.
  • Grade 6: Students learn how non-flowering plants (spore-bearing and cone-bearing plants, ferns, and mosses) reproduce.
  • Grade 7: Students learn that asexual reproduction results in genetically identical offspring, whereas sexual reproduction leads to variation.
  • Grade 8: Students study cell division via mitosis and meiosis, understanding that meiosis is an early step in sexual reproduction that leads to variation.
  • Grade 9: Students study the structure of genes and chromosomes and their functions in transmitting traits.
  • Grade 10: Students are introduced to the structure and function of DNA and learn that changes in sex cells are inherited, while changes in body cells are not passed on.

Senior High School Genetics

  • Earth and Life Science (for Non-STEM students):
    • How genes work.
    • How genetic engineering is used to produce novel products.
  • Biology 2 (for STEM students):
    • Mendel's Laws of Inheritance.
    • Sex Linkage.
    • Central Dogma of Molecular Biology.
    • Recombinant DNA.
  • The relevance of learning genetics for prospective science teachers is apparent, as it equips them with the necessary knowledge and skills to teach Life Science topics in the K-12 curriculum.
