David, a college senior majoring in history, was concerned that his knowledge of history would be insufficient to teach high school. he was considering enrolling in more american history courses to prepare himself for the classroom. according to research about teacher effectiveness, what is most likely a better use of david's time as he prepares to teach

I believe the answer is: Developing an understanding of the content of the school curriculum that students will be expected to know

By developing an understanding of the content, David would most likely able to presented his teaching in a more unique and non-monotone way without missing the core information. This would most likely increase the student's interest and understanding in david's classes.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
