Final answer:
In the 1970s, educational reformers pushed for an increased focus on science and mathematics in the school curriculum to align with the new industrial economy's requirements and to prepare students for modern professional fields.
Step-by-step explanation:
During the 1970s, educational reformers sought to promote greater emphasis on science and mathematics in the school curriculum. This shift was partly due to a recognition of the increasing importance of technical and trade skills in the new industrial economy, leading to an emphasis on vocational education. Coupled with this was the need to prepare students for the modern work world, especially in realms such as engineering and business, where strong skills in science and mathematics were vital.
The growing trend in education reflected a broader shift in societal needs and the job market. There was a focus on building human capital and ensuring that education systems provided the necessary knowledge and skills. Educational policies, therefore, supported heavy investments in primary and secondary education with a particular emphasis on math and science education, which are key for various professional fields, including engineering and business.
