Assessment Plan “The Ear: An Amazing Sound Machine”

Standard

Assessment Plan “The Ear: An Amazing Sound Machine”

 The purpose of this lesson plan is to introduce students to the basic structures and terminology of the human ear.  Students will learn how sound travels through the ear and how different structures work together to produce sound.  Students will also be introduced to the different ways animals use their ears to hear.  The student will learn how the shape and size of the ear determine how an animal uses their ears to adapt to their environment.  Upon completion of this lesson the student will be able perform the following learning outcomes by answering each of the five questions provided:

Learning OutcomePoint to five different structures of the ear.

Test Question:Upon completion of instruction and given a model of the ear, the student will be able to point to each of the following structures of the ear:  eardrum, cochlea, hammer, anvil and stirrup.

Learning Outcome:  The student will explain what part of the ear helps a person to hear and explain why.

Test QuestionExplain in a minimum of two paragraphs what part of the ear helps a person to hear.  Provide an explanation of why?

Learning OutcomeExplain how sound is transmitted through the ear.

Test QuestionExplain in a minimum of three paragraphs how sound is transmitted through the ear.

Learning Outcome:  Explain how animals use their ears to survive.

Test QuestionExplain in a minimum of three paragraphs how animals use their ears to survive.

Learning Outcome:  Correctly identify which vibrates first, the eardrum or the tiny bones in the middle.

Test Question: Identify which vibrates first, the eardrum or the tiny bones in the middle ear?

The context of this assessment is to measure student understanding after a brief lesson about the ear.  This is not a cumulative test but rather a check point assessment to measure student understanding of the material covered as the instruction is given.  This is the first of several assessments that will be taken prior to the cumulative test that will include everything measured in each check point review.  The short five question assessment will provide insight for the instructor as well as the student by offering  short assessments along the way.   The instructor has the ability to see if what they are teaching is reciprocated effectively while at the same time providing a way to review topics that the student(s) may have not grasped.    The student an  the content covered by explaining through short essay formatted questions the student’s ability to summarize what they have learned throughout the lesson.

The holistic rubric for this assessment will assign a single numerical value that will represent a specific category of completion.  The rubric will provide defensible and efficient feedback of student understanding.  The scoring system will demonstrate areas of competency as well as discriminate areas where the student may need further review.  The following rubric is based on a five scores that measure five criterion’s of knowledge.  The assessment will measure the student’s ability to understand and remember information. The scores apply as followed: 1 = element is missing, 2 = minimally satisfies, 3 = partially satisfying, 4 =mostly satisfies and 5 = fully satisfies.  The student can earn a maximum of 25 points with each question being worth five points each.  Limiting the number of points the assessment is worth makes an assessment easy to use and reliably discriminating.  The rubric also provides  percentage results by taking the score and dividing it by the maximum number of points the student can earn.  Grades are determined through percentage rank.  Although percentages are an extremely limited measurement tool to evaluate overall student achievement, they work well for this assessment by providing a quick overview of student progress.

The testing constraints will be limited to a time of approximately 30 minutes to answer five questions that include objective and performance assessments.  Students will be given clear instruction at the beginning of the lesson that an assessment will follow a review of the material covered.   A complete and thorough review of the questions covered in the assessment will be discussed prior the student taking the test.   The student will have an understanding of where the structures of the ear are located on the 3D model and have an opportunity to perform what the assessment is asking the student to by working with the 3D model prior to taking the assessment.  This assessment is measuring student comprehension and application of knowledge and the results will be used to determine areas of student proficiency and areas where more review is needed.  The assessment provides a preventative measure to ensure that the student does not fall behind as the lessons continue, providing the student with an excellent opportunity to master skills prior to taking the cumulative test.

In conclusion, the assessment will provide valuable information on what the student is learning before deficiencies in learning begin.  By providing short assessments along the way, the test giver will ensure consistent results that demonstrate whether learning is taking place.

Assessment Rubric

Criterion Score, from 1-5:1= element is missing2= minimally satisfies3=partially satisfies4=mostly satisfies5= fully satisfies
1. Does the student point to five different parts of the ear?
2. Does the student clearly explain what part of the ear helps a person to hear and why?
3. Does the student clearly explain how sound is transmitted through the ear?
4. Does the student clearly explain how animals use their ears to survive?
5. Does the student correctly identify the structure in the ear that vibrates first?

Total (maximum 25)_________
