Why teaching aids and instructional materials for promoting Learning of Science and technology in School ?

Importance of application of teaching aids and instructional materials in learning science and technology.

Practical use of teaching aids and instructional materials had shown that use of teaching aids ,and instructional materials can contribute positively to Learning of subjects in the classroom , mostly especially learning of science related subjects .It is Learned in Human learning theory in the psychology of Education that use of tools and materials facilitate the teaching and learning process ,and help the teachers to teach effectively, also help the students to exhibit the behavioural objectives highlighted  in the Curriculum of Education. 

A school that lack good teaching models and teaching aids can never deliver the content of Curriculum  Successfully . Many scientific problem-solving approaches and concepts will be too abstract for the Students and they become half baked students, then they struggle to apply their knowledge and concepts  and lack confidence for External Examination  . The  most Challenging issues facing Success of educational system are lack of teaching aids , lack of knowledgeable teachers to use teaching aids effectively, and lack of facilities.  Research and findings had shown that the students that attend schools that have qualified teachers, well equipped science laboratories and Technical workshops perform brilliantly in External Exams.  

However, a teacher that is teaching without appropriate teaching aids and Learning materials is a real quack, because the teacher is teaching what he or she didn't know, and it will be very difficult for someone to give out what he or she doesn't have. While teachers using teaching aids and learning materials teach   and  deliver content of Curriculum effectively and sustain interest of the students, the quack will be struggling to deliver Content of Curriculum. Proper continuous assessment and  teaching aids are very important classroom tools for teachers to input information properly in the memory of students and these help them to recall their previously learnt knowledge and concepts when solving problems.
