Assessment Planning

| |Pre-Test |Post-Test |

|Clear Purpose: |The pre-test was designed with regard to the |See pre-test. |

| |Maryland VSC standards. I looked closely at what |Also included in the post test design was a performance part|

| |students were expected to know/understand and gave |the required students to identify an unknown mineral using |

| |each standard a “weight”. The assessment was |their observation charts that they were responsible for |

| |designed with these weights, the VSC, and a |throughout the course of the unit. I also included |

| |post-test in mind; meaning, I designed the pre |additional questions to the post test that met with VSC |

| |assessment to also act as the culminating post |standards but were not appropriately addressed in the |

| |assessment. Truly I was designing a post assessment|pre-test to match how they were taught in class. |

| |all along. | |

|Clear Targets: |The learning targets that the assessment focused on |VSC standards (see test planning form) |

| |were strictly VSC standards. Because the VSC | |

| |standards are what students will eventually be | |

| |responsible for, I designed the assessment according| |

| |to the VSC. (see test planning form) | |

|Sound Assessment design: |Self evident in the assessments |

| |(see assessments) |

|Good Communication: |Written and oral directions were given before and during the assessment. |

| |Written directions are self evident in the assessments |

| |(see assessments) |

|Student Involvement: |Students verbally responded to problems through extended written response questions. Students were also required|

| |to keep a running observation chart during the unit that was used during the performance portion of the post |

| |assessment. (see attached) |

|1pt-details about formation |

Igneous: rocks formed when melted rock material cools and hardens, can form from lava or magma (accept either).

Sedimentary: rocks formed on the earth’s surface when sediments are compressed.

Metamorphic: new rocks that form from existing rocks by undergoing a change caused by heat, pressure, and chemicals.

Unit Roadmap:

Day 1: Students will complete a Rocks and Minerals pre-assessment and a whole-class

KWL chart about rocks and minerals.

Day 2: Students will practice making “good observations” by observing people, plants,

animals, and still life in their science journals.

Day 3: Students will explore the five properties of minerals: naturally occurring,

inorganic, solid, definite composition, and regular internal structure. Students will test inanimate objects through the five properties and discuss why or why not they fit each property.

Day 4: Students will apply their knowledge of the properties of minerals to differentiate

between rock and mineral samples in a mixed set.

Day 5: Students will begin their properties of minerals observation charts to explore

color and luster of their 12 piece mineral sets

Day 6: Students will explore Moh’s scale for mineral hardness and record their findings

in their observation charts.

Day 7: Students will explore different mineral streaks as well as identifying

characteristics of some “special” minerals. Students will record their findings in their observation charts.

Day 8: Students will explore the three different types of rocks: Igneous, Metamorphic,

and Sedimentary.

Day 9: Students will complete a rocks and mineral sampling of their backyards and/or of

the playground. They will identify their samples using the rock key and mineral tests (observation charts). The students will compile their data and make a class graph of St. Mary’s County geological resources.

Day 10: Students will compare their backyard findings to the actual St. Mary’s County

geological surveys using county mineral/soil maps.

Day 11: Students will complete a post-assessment and finish their KWL charts from the

first day.

Figure 3. 2-sample t-test used for analyzing significant differences in student scores between pre and post tests

Analysis:

The t-test returns a p-value which can be used under different certainties to determine whether or not the students’ scores changed significantly. Significance can be held under different alpha values. If a p-value is less than the set alpha value, the comparison in populations is said to have a significant difference-it could not have happened by chance. When the alpha-value is set lower, (i.e. 0.01 vs. 0.05) the significant difference increases-it is less likely to have happened by chance.

For example:

p (1.0681 E -10) < 0.05 shows a significant difference*

p (1.0681 E -10) < 0.01 shows a “highly” significant difference**

Given the class pre and post score data, we can say with 99% confidence (p ................
