Answer:
. c. tracking has no real impact on student performance after elementary school.
Explanation:
Tracking is a method often applied in education system, in which there is separation of students by academic potential such as observed ability, IQ, or achievement status into various categories for course or specific classes and curriculum within a school.
Those with low scoring ability are placed on lower tracks, those with average academic potentials are placed in the middle tracks, while the top performers are generally placed in higher tracks.
The higher the tracks, the better and relatively wider the subject being taught.
Hence, research on tracking has found all of the following except "tracking has no real impact on student performance after elementary school."
The answer Is feldspar
it is a rock-forming mineral which has particular importance in the glass and ceramics industries since it works as a fluxing agent. This means that feldspar reduces the melting temperature of quartz, consequently helping to control the viscosity of glass. Moreover, this rock-forming mineral is one of the most common minerals in existence, forming approximately 60% of earth’s terrestrial rocks. Finally, each year about 600,000 tons of feldspar is mined in the United States from quarries in South Dakota, Oklahoma, Virginia, California, North Carolina, and Idaho. Besides this, vast deposits of felspar exist throughout the world, but the greatest challenge remains extracting and transporting the minerals to the point of consumption.
Answer: D. Rats appear to experience latent learning while exploring mazes.
Explanation:
An experiment by Edward C. Tolman showed that organisms can learn especially latently without immediate reinforcement like Skinner opined even though the learned behavior will not manifest itself unless there is sufficient stimuli to do so.
Rats in his experiment were put in mazes without food as a reinforcement and as a result they developed a sort COGNITIVE MAP of the maze such that when food was eventually put there they were able to get the the food quickly.
