Final answer:
The authoritarian leadership style can result in a discontented, hostile, but productive group in the classroom.
Step-by-step explanation:
The leadership style that results in a discontented, hostile, but productive group in the classroom is the authoritarian leadership style.
An authoritarian leader is someone who issues orders and assigns tasks, with a strong focus on meeting goals. While this style can be effective in certain circumstances, such as in emergencies or when clear direction is needed, it can also lead to alienation and hostility among group members.
For example, imagine a teacher who constantly gives orders and demands obedience without considering input from the students. While the group may still be productive in terms of completing tasks, the members may feel discontented and hostile towards the leader due to the lack of autonomy and involvement in decision-making.
