G8 Embedded PT – Chemical Reactions Administering this Performance Task

2018 Sample Task

What Is an Embedded Performance Task? Embedded performance tasks (PTs) are activities assessing the California Next Generation Science Standards (CA NGSS) for students eligible to take an alternate assessment for CAASPP. The CA NGSS are accessed through Core Content Connectors. The results of the PT are intended to provide information about the student’s degree of mastery of the Focal Knowledge, Skills, and Abilities being assessed and to identify where additional instruction is needed.

What Information Is Included with the Embedded Performance Task? Each PT includes the following:

Task Standard Table Task Materials List Student Response Check Activities Student Survey

(questions answered by thestudent and entered by the testexaminer)

Student Engagement Survey(completed by test examiner aftertesting)

Answer Recording Document Related Graphics and Tables

When Do I Administer the Embedded Performance Task? The embedded PTs are designed to be administered to students following the normal course of instruction related to the Connector being assessed. The Connector being assessed can be found on the Content of Instruction page. The test examiner (TE) should administer the embedded PT immediately after the student has received instruction aligned to the Connector.

How Do I Administer the Embedded Performance Task? 1. Decide on an administration date that falls shortly after the normal course of

instruction.

2. Review the activities associated with the embedded PT. Based on this review of thetask activities, including needed materials, activity setup, and activity processes,determine if the Exemplar Activity will be presented or if an Individualized Activitywill be presented.

If an Individualized Activity will be presented, the test examiner also shouldindividualize and document designated activity directions where indicated.

If a task contains an activity that is not easily repeatable in multiple one-on-oneadministrations, a test examiner may present that activity in a group setting or usea video of that activity to present to students. The video can then be used in theone-on-one administration of the performance task.

2018 Sample Task

Each activity has Preparation and Administration instructions.3. Gather and/or print necessary activity materials.

4. Print an Answer Recording Document for each student to whom the task will beadministered. You will use this document later to enter results in the online DataEntry Interface (DEI).

5. Complete the Preparation Instructions.

6. Administer the activity according to the Administration Instructions.

Statements for the test examiner to say are marked: .

Actions for the test examiner to do are marked: .

How Do I Record the Results of the Embedded Performance Task? Test examiners will record task administration data for each student on the task Answer Recording Documents. As the task is administered to the student, information to be placed on the answer recording document is marked by a shaded diamond. The number in the shaded diamond matches the number on the Answer Recording Document. After the embedded PT is administered, the test examiner should save the Answer Recording Document in a secure location. At a designated time, the test examiner or CAASPP coordinator will input embedded PT results into the DEI. The DEI can be found at http://www.caaspp.org/dei/. Instructions for using the DEI and other CAA resources can be found at http://www.caaspp.org/administration/about/caa/.

G8 Embedded PT – Chemical Reactions Content of Instruction

2018 Sample Task

Overall Content of Instruction

Performance Expectation MS-PS1-2

Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

Connector Using data through observation, identify evidence that proves a chemical reaction has taken place (e.g., change in color, gas is created, heat or light is given off or taken in).

Essential Understanding Identify examples of change (e.g., state of matter, color, temperature).

Focal Knowledge, Skills, and Abilities: How mastery is demonstrated:

Ability to identify evidence that proves a chemical reaction has taken place (FKSA 1)

Stating that a chemical change took place based on data (formation of bubbles, temperature change, color change).

Essential Understanding Recognizing a change in state (freezing, melting, vaporizing), temperature or color.

Focused Content of Instruction

Activity Instructional Focus Skill Assessed

1

Students will be taught to recognize the kinds of changes that show a chemical reaction has occurred when two substances are combined.

To assess whether the student can observe the combination of different substances and identify when a specific type of change occurs that is indicative of a chemical reaction.

2

Students will be taught about the kinds of physical changes that occur in substances.

To assess whether the student can observe physical changes in different substances and identify the kind of change that has occurred.

G8 Embedded PT – Chemical Reactions Student Response Check

2018 Sample Task

Prior to beginning the embedded performance task, the test examiner should conduct a Student Response Check with the student. The purpose of the Student Response Check is for the test examiner to check if the student has a consistent and observable way of indicating responses to test questions. Student response modes may include indicating an answer with a mouse or keyboard, verbalizations, pointing, and/or gesturing. Students also may respond using eye gaze and an assistive communication device.

Administer the Student Response Check by selecting three of the objects from the Materials List on pages 6-7 of this task. Show the objects to the student. Direct the student to identify one familiar object in the set of objects, using the student’s mode of communication. For example, “show me the cup.” If the student does communicate an observable response, even if the selection is incorrect, administer the embedded PT.

If the student does not communicate an observable response, do not administer the embedded PT. However, the TE must still respond to the question below in the Data Entry Interface (DEI).

Did the student orient and respond during the Student Response Check?

A. Yes (Administer the PT)

B. No (End administration)
