Introduction to Evolution

To a degree, this type of lesson has been going fairly well.  Several reviews have mentioned liking the PPT format being outlined as Cornell Notes, doing pair shares throughout the class time to check for student understanding and the use of quiz cards for helping students with new and challenging vocabulary and with harder concepts.

After teaching the lesson, which is very similar to most of the lessons we do, a few thoughts have emerged.  During the pair share portions we have a space where we have them add one question to the side of their notes and after a few minutes we move on. I think it would be better to immediately review what questions have been written down and make it quick, down and dirty review session to help the whole class.  It would get them involved and break up the day.  I also think for periods of teaching where we are labeling something, such as labeling the cell, getting students to come up to the board and do it together and then have them do it individually would help with students not loosing interest and be more involved.

1. TITLE OF THE LESSON
Ecology – Evolution Introduction
2. CURRICULUM AREA & GRADE LEVEL
Biology 1A – 9/10
3A. STUDENT INFORMATION: English Language Learners
        1.) Readiness Level
2 ELL, all are above a 3.
Carlos-Recent immigrant, good English and fluent in Spanish.  Does not like to read. No previous Biology
Alleta-Good writer but poor reading comprehension. Had previous Biology but doesn’t remember much.
        2.) Learning Profile
      Psycomotor, Auditory
        3.) Interest
Soccer, friends and family
3B. STUDENT INFORMATION: Students w/ Special Needs
        1.) Readiness Level
Student with SLD – Has problems with auditory processing and reading comprehension (short term Memory)    
        2.) Learning Profile
Student is a multi Mododal learner and needs information and instruction in a variety of ways to acquire content   
        3.) Interest
N/A
4. RATIONALE
     A. Enduring Understanding- Long term relations, how everything is connected.
What is Evolution?  How does Natural Selection affect differential survival of groups of organisms? Define and explain the mechanisms of Natural Selection.  How does geographic isolation affect speciation?
B. Essential Questions
What is natural Selection?  Who is Charles Darwin?  Explain the types of evolution-Macroevolution and Microevolution. How does Isolation affect evolution?  
     C. Reason for Instructional Strategies and Student Activities
Student activities will increase retention by explaining concepts to their partners.  Small group pairing is less intimidating so students are more likely to participate.
5. CONTENT STANDARD(S)

7d – Students know variation within a species increases the likelihood that at least some members of a species will survive under changed environmental conditions.

8a – Students know how natural selection determines the differential survival of groups or organisms.

8d – Students know reproductive and geographic isolation affects speciation.
6. ELD STANDARD(S)
      
Listening and Speaking 5I – Participate in social conversations with peers and adults on familiar topics by asking and answering questions and soliciting information.

El students are assessed at the I+1 standard and will be assessed during pair share activities and within response to specific Q&A from teacher.

7. LEARNING GOAL(S) - OBJECTIVE(S)
     A. Cognitive
After the PPT lesson SWBAT students will demonstrate their understanding by answering and explaining what evolution is.  SWBAT define Natural Selection and explain it affects differential survival of groups of organisms? SWBAT explain how geographic isolation affect speciation? 
     B. Affective
Students will demonstrate their understanding through observed pair/share activities where the students are asked questions related to Evolution and Natural Selection and what they mean and how they are related through classroom activities such as think/pair/share, relating concepts taught to real world examples or experiences.  For example, moths have protective camouflage for particular backgrounds.
     C. Psychomotor
At the end of this lesson, students will Create of quiz cards with definition or concept on one side and the answers on the other.  They will further do summary writing at the end of the period on the topic(s) that was just covered.  As I walk around, I’m looking to see if they can put the ideas of the day into a sentence or two or that they are at least trying.  Writing both quiz cards and summary makes them review information again, read it and then write it again.
D. Language Development
Vocabulary and terminology of related topics will be explained.  Complicated words are said aloud with the whole class, with student repetition and break down of what it sounds like and what it’s meaning is.

8. ASSESSMENT(S)
      A. Diagnostic/Entry Level
Students will do a quick write on what knowledge they have or heard on the upcoming topic.  Bullet points are ok. 
B. Formative – Progress Monitoring
Students will be assessed during daily homework checks and incorporating teacher observed pair-share blocks throughout each class.  Individual Q & A throughout class, where I present questions to everyone and then choose 3-4 students to answer and share aloud.  In addition, students will write summaries at the end of the lesson or will be given essays to do as homework.
C. Summative
Weekly open note quizzes with self-grading by students and teacher guidance to correct answers.  Students will be able to self evaluate their progress in understanding vocabulary and concepts.  Students will further be assesses through end of Unit exams covering content from last test.  Included are essay questions for conceptual understanding and being able to apply what they have learned.

9A. EXPLANATION OF DIFFERENTIATION FOR
ENGLISH LANGUAGE LEARNERS
1.)   Content/Based on Readiness, Learning Profile or Interest
Students keep Biology notebook where they use Cornell notes for organization of power Point presentation.  For homework and in class, students make quiz cards of current vocabulary terms and or concepts for the day.  Checked throughout the week as a homework assignment.
2.)   Process/Based on Readiness, Learning Profile or Interest
Through think/pair/share students learn to explain ideas and concepts to partner.  Even simply repeating the notes as verbal practice is observed and encouraged.          
3.)   Product/Based on Readiness, Learning Profile or
Interest
9B. EXPLANATION OF DIFFERENTIATION FOR
STUDENTS WITH SPECIAL NEEDs.
1.) Content/Based on Readiness, Learning Profile or Interest
Students keep Biology notebook where they use Cornell notes for organization of power Point presentation.  For homework and in class, students make quiz cards of current vocabulary terms and or concepts for the day.  Checked throughout the week as a homework assignment.
2.) Process/Based on Readiness, Learning Profile or Interest
Through think/pair/share students learn to explain ideas and concepts to partner.  Even simply repeating the notes as verbal practice is observed and encouraged.

Increased verbal explanations through pair/share activities linking written notes to oral recognition.  HELP!!!!!                

10. INSTRUCTIONAL STRATEGIES
(Describe what the teacher does. Include differentiation strategies.)
       A. Anticipatory Set/Into
Students are instructed to work on bellwork, answer question of the day and write out HW assignment.  Question of the day: What is the evidence of Evolution proposed by Darwin?
(8 min)                       
       B. Instruction/Through
Provided through Power Point presentation to introduce students to new Unit on Evolution. (30 min)                                             
       C. Guided Practice/Through
Students are instructed to pair share with their partner to answer questions and terminology asked by teacher about Evolution/Natural selection.  Teacher calls on random pairs to discuss concepts or vocabulary. Twice throughout the lecture.
(5 min/each – 10 min)
D. Independent Practice/Through
Demonstrate Cornell note taking within PPT lecture with pictures of what it looks like and how it’s used.  Entire PPT is laid out as a template for students to follow.  For independent practice students make quiz cards as homework and for studying.  (8 min)
E. Closure
