Based on the Passage given below answer the questions.
The distribution of opportunities for learning available in a society is an important factor that influences both how 'worth' of a certain kind of knowledge is perceived or weighed and how knowledge that is regarded as worthy of being taught will be represented in educational materials. We can take for granted that the knowledge relevant or related to groups whose access to education is poor will not be regarded as worthy of being taught in schools. The knowledge of animal behaviour and medicinal plants that the Baigas have acquired over a length acquaintance with the jungles of central India is unlikely to be regarded as worthwhile educational knowledge. Baiga children have poor access to opportunities for education and their chances of doing well at school are very slim at least partly because the Baiga's life finds no resonance in the school curriculum.
How the method of teaching affects the character of what is taught can be seen in the teaching of science. The distinctness of science as a school subject comes from the need for experimentation by the learner. As a subject that demand experimentation and independent inquiry by the learner, science is associated with freedom of judgement and equality between the student and the teacher in the presence of objective facts. Science education is supposed to be conducive to secular values precisely because it makes ascribed authority redundant. But if science is taught in a traditional manner with the authority of the textbook and the teacher's word and without opportunity for experimentation it would cease to have a secular character and value. Once it loses its original character owing to the application of conventional pedagogies, science can easily become an instrument for authoritarian control in the classroom and in society. The practice of science in a milieu that does not permit equality or open questioning might lead pupils into imbibing values that are antithetical to science. Also science can reinforce existing structure of dominance if its content and the method of teaching are not reorganised from the perspective of powerless social groups.
Not just the character of what is taught but the volume of content, too, is affected by the methods of teaching.
