Final answer:
The "free field effect" for teachers can be encouraged by school boards through incentivizing measures such as regular student testing, rewards for good performance, additional teacher training, educational choice, and financial support for salaries and supplies.
Step-by-step explanation:
School boards can generate the "free field effect" for teachers, which refers to an environment where teachers feel supported and motivated, by implementing various incentive-based measures. To foster this effect, there are several proposals that school boards can consider. For instance, testing students regularly provides teachers with frequent feedback on student performance, while rewarding teachers or schools that perform well on such tests can offer tangible recognition and motivation. Additionally, requiring additional teacher training can enhance professional development and outcomes and allowing more choice in education through measures such as letting students choose between public schools, permitting teachers and parents to start new schools, and giving students "vouchers" to select their preferred educational institutions. Moreover, financial support can be enhanced by offering supplementing teacher salaries or providing money for necessary equipment or supplies.
