What is the purpose of the Essential Science Concepts for Exit-Level TAKS (ESCET)?
To prepare students to be successful on the exit-level TAKS.
To provide an alternative to a traditional “drill-and-kill” review for the exit-level TAKS.
4
What is the purpose of ESCET ProfessionalDevelopment?
• To provide teachers with a tool that helps to identify the content and process skills that students need to master before taking the exit-level TAKS.
• To provide tools that can be used to determine the science content that teachers need to review, reinforce, or reteach.
5
ESCET consists of two modules: Biology and Integrated Physics and Chemistry (IPC).
The IPC module contains 16 activities, and the Biology module contains 17.
The modules address all the student expectations assessed on the exit-level TAKS.
What are the ESCET modules?

How can the modules be implemented?
Administer the modules separately Give all the Biology activities together and
all the IPC activities together. Rotate students through the activity stations
the way you would move them through a lab
practical. Have students work in teams of two.
14
How can the modules be implemented?
Alternating the activities
Alternate an IPC activity with a Biology activity.
This method integrates the activities in the same way that the Biology and IPC questions are integrated on the exit-level TAKS.
15
How can the modules be implemented?
Multiple sets of a single activity
A room may contain multiple sets of one IPC or Biology activity with two teachers.
Teachers assigned to a small group of students
Teachers serve as specialists for three activities, and groups of 4 to 6 students work through the activities with support from the teacher.
16
What are the students’ responsibilities?
As a team, students…
examine the Station Information Sheet and verify the station setup.
read and answer the Focus Question.
follow the procedures in the Student Pages.
answer the TAKS question on the Question Card.
post their answers on the Diagnostic Wall Chart.
