Study Notes
Teaching Methods
-
Lecture Method
- Principles: Teacher-centered, controls all aspects of instruction, used to impart complete knowledge to passive students, emphasizes content presentation.
- Advantages: Economical (time and resources), systematic presentation of subject matter, effective in presenting new material to students, develops good audience habits, effective in linking prior knowledge to new.
- Disadvantages: Too teacher-centered, renders learners inactive/passive, teaches to the average learner, ignores individual differences, does not promote higher-order thinking skills.
-
Inquiry-Based Learning (IBL)
- Principles: Learner-centered, aligns with constructivist ideals, uses models like the 5E Model, starts with questions to be explored by learners.
- Advantages: Improves learner engagement, enhances mastery learning/knowledge retention, promotes teamwork, enhances development of higher-order skills, allows for authentic student assessments.
- Disadvantages: Requires significant planning by the teacher, time-consuming, resource-intensive, learners may lack requisite inquiry skills.
Levels of Inquiry
- 1-Confirmation Inquiry: Students confirm a principle when results are known in advance.
- 2-Structured Inquiry: Students investigate a teacher-presented question through a prescribed procedure.
- 3-Guided Inquiry: Students investigate a teacher-presented question, using student-designed and selected procedures.
- 4-Open Inquiry: Students investigate student-formulated questions through student-designed and selected procedures.
Inquiry-Based Learning (IBL) - Essential Components
- 1. Orientation/Observation: Teacher introduces a new topic, and students explore it through research, direct instruction, and hands-on activities.
- 2. Question/Conceptualize: Students develop questions related to the topic, making predictions and hypotheses.
- 3. Investigation: Students take initiative (with teacher support) to discover answers, gather evidence, and conduct research to support or disprove hypotheses.
- 4. Conclusion: Students develop conclusions and answers to questions, determining correctness of hypotheses, which may lead to further questions.
- 5. Discussion/Sharing: Students present results, engage in discussions, and encourage debate and additional questions.
The 5E Model of Inquiry
- Engage: Preparation phase to introduce concepts and pique student interest.
- Explore: Students actively experiment and strategize to answer questions.
- Explain: Students report & explain their findings with evidence.
- Elaborate: Develop a deeper understanding of concepts and make connections through discussion.
- Evaluate: Informal or formal assessment of understanding.
Practical Work in School Science
-
Activity Focus: Role of practical work, types of practical work, characteristics, and strengths/weaknesses.
-
Role of practical work (physics): Develops practical skills, enhances conceptual understanding, promotes scientific attitudes, motivates learners.
-
Development of scientific skills: Includes manipulative skills, accurate observation/recording, data processing/analysis, communication skills, problem-solving, and competency in scientific investigations.
-
Enhancing conceptual understanding: Demonstrates scientific facts and principles (verification), and understanding of the theoretical aspect.
-
Promoting scientific attitudes: Appreciation of scientific method, evidence-driven approach, open-mindedness, promoting logical reasoning, ability to recognize & solve real-world problems.
-
Motivation: Use of practical work to arouse and maintain learner interest in science.
-
Types of practical work (Gott, Welford & Foulds, 1988): Skills practical, observation, illustration, inquiry, and investigations.
-
Skills practical: Aims to develop basic practical science skills, examples include setting up apparatus, using instruments, and plotting graphs.
-
Observation practical: Aims to develop observation skills, examples include observing bimetallic strips, water in a test tube, and explaining observations.
-
Illustration practical: Aimed at demonstrating or confirming concepts/laws. Teacher demonstration or student-led practical, following instructions from teacher. Examples include confirming Hooke's Law, demonstrating relationships between current and voltage
-
Inquiry practical: Learners 'discover' scientific phenomenon. Can precede or follow the teaching of concepts/laws. Learners may receive some guidance.
-
Investigations: Involves planning and conducting scientific experiments. Learners formulate questions, plan procedures, collect data, interpret, and evaluate data. Design less controlled than inquiries and illustrations.
