All of the students that I observed were, according to Piaget, in the formal operational stage. According to Moreno, this means that students are able to engage in logical and systematic thinking. They are able to apply the wide repertoire of cognitive abilities and are able to think hypothetically. This means they are able to conduct "thought experiments" and think in terms of metaphors, ironies, analogies and satire. Learners are able to use propositional logic, which is the ability to judge the internal consistency of arguments even when the arguments are at odds with reality. They are able to engage in hypothetical deductive reasoning, which means they can generate and test hypotheses or predictions by separating and controlling variables. Learners can use analogical reasoning, which is the ability to understand how something more familiar works. They can also use combinational reasoning, which is the ability to conceptualize how several elements might be combined. A formal operational thinker can also solve problems involving probability and proportional reasoning.
During on lesson, the teacher asked students to name the causes, effects, prior causes and subsequent effects of the Vietnam War. After the students had filled out their charts they were asked to come up with a hypothesis and a conclusion concerning the chart they just filled out. This could not have been done with students in the previous stages in Piaget's stages because they are not able to think hypothetically or propose hypotheses.

To keep students in their zone of proximal development, the teacher I observed practiced scaffolding by giving students a lecture guide that they would fill out as he lectured. This guide provided terms of the important information that they needed to know for the exam at the end of the unit. This helped students to know what information was critical and what they needed to remember for the exam. Vygotsky also believed in guided participation and apprenticeship, which the teacher did not use while I was observing. I think that it is easier to use these kinds of instructional methods during a math or science lesson. You could use guided participation in history by teaching your students to write a good research paper, or how to do research on the internet. In guided participation, students engage in learning activities with a more capable others who provides the medication and encouragement needed to acquire new knowledge and skills. In apprenticeship, students experience a one-on-one relationship with a more capable other and they actually learn the thought process of the more capable other. The teacher explains why they are doing what they are doing so eventually the student can think like the teacher, instead of just doing it because "that's the way you do it".
