LABORATORY WORK

What?
- Most of us will say is experiment
- It engages students in finding out & learning through experiences
- It can be used to promote the learning outcomes like attitudes toward science, scientific attitude, scientific inquiry, conceptual development, and technical skills

Approaches to laboratory work:

1. Science process skill
- the inquiry skills engage in investigation are observing and inferring, measuring, hypothesizing, communicating, and experimenting

2. Deductive or verification
- General to specific
- To confirm concepts, principles, and laws that have been delivered during classroom discussion and reading
- Help to reinforce subject matter content in the class

3. Inductive
- Opposite of deductive
- Specific to general
- To develop concepts, principles, and laws through firsthand experiences before the idea is discussed in the class

4. Technical skill
- Essential for conducts successful laboratory activities and obtain accurate data
- Manipulative skills: development of hand-eye coordination such as focusing a microscope, sketching specimens, measuring angles, and cutting glass
- Knowing the experimental techniques well and orderliness
- psychomotor & mental practice are beneficial in improving accuracy & precision of students’ laboratory measurements

5. Problem solving
- Students are given the opportunities to identify problem, design procedures, collecting information, organize data, and report the findings
- Involve authentic inquiry experiences for students
