decreases it.

12) Three of the following are definite examples of scaffolding. Identify the situation in
which no scaffolding is described.
a.Ms. Ayotte likes to challenge her students by giving them group research projects. She
puts her students in groups of three or four students each, and she gives each student a
topic to research. She sends the groups to the school library to find out as much as they
can about their topic, and then has each group give a report to the entire class.
b.Mr. Bender is teaching a unit on beginning tennis. In the early stages of teaching a
correct tennis swing, he uses an automatic ball server that serves balls with consistent
speed, height, and direction. He also continually reminds students to Keep your eye on
the ball and Hold your arm straight. Later in the unit he begins to serve the balls
himself, varying the speed, height, and direction of the serves. And he reminds students
of what to do much less frequently.
c.Ms. Carrera helps students solve math word problems by providing visual illustrations
of the elements of the problem and by showing them similar problems that have been
worked out correctly. As the weeks go by, she provides fewer and fewer visual
illustrations and fewer and fewer worked-out examples, until eventually the students
can solve the problems without either form of assistance.
d.Mr. Donaldsons students are just beginning to learn how to take notes in class. For the
first few weeks Mr. D. begins class by handing out a detailed outline about the topic for
the day. By December he is handing out an outline covering only the main points of the
day, encouraging students to fill in the blank spaces on the sheet with ideas relative to
each point. By May, students are writing down main points and relevant details on their
own.
13) Knowing what famous people look like reflects knowledge that is stored in
