Which of the following is not an environmental factor affecting…

Factors affecting teaching-learning are classified into environmental (external) factors and individual/organismic (internal) factors. Environmental factors are conditions or resources present in a learner's surroundings, such as instructional materials, physical or classroom conditions, and facilities made available to the learner, which come from outside the learner. Individual factors, by contrast, originate within the learner's own biological and psychological makeup, such as maturation, motivation, and intelligence.

Learning material, physical conditions, and recreational facilities are all external resources or conditions supplied within the learner's surroundings, so each of them is an environmental factor. Maturation, however, is the natural, genetically timed process of biological and psychological growth that originates primarily within the learner, so it is an individual factor rather than an environmental one.

• Learning material is an external instructional resource provided to the learner, so it is environmental.

• Physical conditions are the surrounding classroom conditions, such as lighting, seating, and noise, in which learning takes place, so they are environmental.

• Recreational facilities are external provisions, such as playgrounds and sports amenities, made available to the learner, so they are environmental.

• Maturation is a biologically driven developmental process that originates primarily within the learner along a genetically timed course, so it is classified as an individual factor rather than an environmental one, which makes it the correct answer.
