Strategy Set

ONE
      A strategy that I think would be highly effective in my classroom for students struggling with reading comprehension would be the Writing Break.  The writing break is a quick comprehension check every 10-15 minutes through a lesson or reading.  This check would take the form of a 4-6 minute writing break during which students restate what they've just learned in their own words, ask any questions, highlight important concepts, etc.  This strategy would be most appropriate for use during long periods of note taking, particularly when the notes are stemming from something read, like a powerpoint or a textbook chapter.  
        This strategy should be used because it gives students an applicitive brain break.  It lets students check their own comprehension, and gives them immediate purpose in learning.  Additionally, it breaks up what may be a longer chunk of notes into smaller, more manageble sections for those who struggle with comprehension.  Specifically, I could be lecturing students about organelles of the cell though an interesting and engaging PowerPoint coupled with small activities.  After every new organelle we cover, students would take a Writing Break to answer the following questions:
           "What is the most important function of the organelle?"
           "What is the weirdest/most confusing thing about the organelle?"
           "Is there anything about this organelle that made you think about something else?"
     As we did this throughout the lesson, it would create a series of breaks in notes and learning to permit students to check what they have learned and summarize the key components of their notes.  However, as students generally don't like the word "summarize" the question series is asked instead in an effort to weed out excess information.  




TWO
The Clustering strategy would be useful for struggling readers, who are often struggling writers.  The strategy creates an overgrown bubble map filled with concepts, definitions, examples, and thoughts, physically linked together by lines.  It works by clustering relative information together in bunches.  It is best used when trying to get students to make connections between concepts, and ideas.  Again, the strategy is used to make connections!  However, the connections aren't in depth, they aren't taxing for an ESL student or a struggling writer.  Additionally, most answers are correct, as long as the connecting line can be defended by a thought process.  This lets students generate connections in a not-stressful or graded situation.  

        This situation sounds like it would be incredibly helpful for large concepts like evolution.  After looking at a chapter, or even a whole unit, I could prompt students by giving them the center bubble, "Evolution".  As a class, we could create a few primary branches leading to Darwin and Mendelian genetics.  The students would each be able to add onto their map the key ideas pertaining to the different points by drawing connections instead of writing out ideas.  The clustering activities could be compared in groups, and then the groups could be compared within the class to create a giant cluster map!  This map, with any tweaking needed, would make a wonderful study guide.  


THREE
I found a Critical literacy strategy that calls for the use of supplementary text.  It's called "reading supplementary texts".  The strategy is used by reading material related to the content currently being covered by class.  This can be done by reading texts that give examples of an idea or theory, simple texts that break a concept down further than the original text, or by showing how an idea may have changed.  This strategy should be used to expand upon an idea, either by restating content that must be known, or by building upon content to peak student interest.  This is most appropriate when a subject may have changed, as it would be in the science field. 

      For example, epigenetics is a hot subject in science right now.  The idea that things a person does NOW, that affect their offspring.  This goes against all popular theories of Mendellian genetics.  It's almost Lamarkian in nature.  In textbooks, Lamark is used as a popular but incorrect theory... but epigenetics has proved Lamark to be correct in certain situations.  Because textbooks do not yet have this information (in high schools any way) a supplementary text on rudimentary epigenetics could be introduced to the students to expand upon the required genetic knowledge into something current and interesting.  This also makes Lamark more memorable, seeing as many students forget about him on their tests because he had been proven incorrect.   


FOUR

PLAN stands for Predict, Locate, Add, and Note.  This strategy is used for reading comprehension.  This strategy is most appropriate for textbook readings, and is used to highlight the important parts of a textbook chapter.  This strategy works by letting students flip through the chapter and look at titles, subtitles, pictures, etc.  and predicting the contents of the chapter.  The student then creates a concept map using these titles and subtitles.  As the student read, he/she Locates the information on the concept map and adds more information to the concept map.  At the chapter's conclusion, the student notes any changes that need to be made to the map due to new understanding, and makes these changes.  

This may be used with homework assignments dealing with textbook chapters within my classroom.  Science textbooks can be confusing, and later components often solve earlier questions.  The PLAN strategy specifically lists out a step for students to modify their notes based on later comprehension, alleviating later confusion caused by strange writing within the textbook.  


FIVE


Making inferences.  This strategy is to make inferences, deductions made while reading text.  Specifically on providing explanations or ideas that are presented in the text.  This strategy is most appropriate for critical reading and comprehension when students are reading academic texts or high level texts.  This strategy ties in personal knowledge to the text and makes students re-explain the text in such a way that they fully understand what they are reading.  This is proved by their re-statement in their own words accompanied by a personal explanation. This strategy works by explaining things that they read, either to themselves or to others, using a different set of words than the text.  

An interesting way to encourage students to do this would be to have them explain things to someone of less scientific knowledge.  For example, if students had a brief article to read for homework, part of the assignment would be to read the article aloud to someone else, and ensure their audience's comprehension.  This way, the student has to slow down and explain "why" to a lay person.  Students could also do this in pairs in the classroom, where their partner has to try to ask as many questions about the article as possible while remaining relevant to the topic.  The prompting from questions would force a student to come up with answers and explanations, or seek out knowledge when they are unable to answer questions.

SIX
Metacognition.  The metacognition strategy is the idea of thinking about one's thinking, becoming aware of the thought process.  This strategy s most appropriate when used to  help struggling readers identify where exactly they are having issues in a text .  This strategy is used to prevent blanket "I don't get it" statements from students, ad can help both teacher and student to resolve the underylying problem in a text.  In order to use the strategy, students recognize that they are having an issue, and then slowly begin to zoom in on the problem.  "I don't understand page 2.  I don't understand the third paragraph on page two.  I don't understand what the word ______ means, and I don't see any context clues."  Once the problem is clearly identified, they can seek a solution within the text, followed by seeking assistance if it is still required.  
This strategy would be useful when looking at a multi-layered scientific concept within a text, such as photosynthesis.  When doing any sort of explanatory reading in dealing with photosynthesis, it's easy for students to become confused if they are confused about any of the components within photosynthesis.  Students could read a text, and write down specific points that confuse them  (what is NaDPh?).  When students complete the text, they will take 3 minutes to look for solutions to their difficulties.  They will then form groups of five and help one another.

SEVEN

Concept Maps.  The concept map is a diverse tool used by students to draw connections or distinguish between ideas.  The concept map isolates individual terms or concepts in boxes or bubbles, and draw lines between these bubbles to draw connections.  These boxes can serve specific purposes (such an antonym to a word or definition) or may merely follow the train of thought.  This strategy is most useful when linear thinking or notetaking would be confusing to students, or when connections between ideas is central to an idea.  This strategy should be used because it's simple, flexible, and yields visual results that readers/writers of all skill levels can appreciate.  Additionally, it can marshal overall concepts used to supplement usual notes.
This strategy would be hugely helpful for layered concepts, like the Cell cycle.  There are three overlying phases in the cycle, two of which have three or more subphases.  A circular concept map could be drawn, showing the three overlying phases, and branching out to the subphases.  The subphase bubbles could include transitory cues, definitions, and diagrams.  Concept maps could also be used as a review of the previous day's information, drawing quick conclusions from memory instead of agonizing over the details.

EIGHT

Roots and Affixes.  This strategy focuses on a teaching/learning components of words so as to increase future reading comprehension.  This is particularly useful idea for biology, as scientific words are often latin based and dissectable.  This would also be helpful for ESL students whose original language is Latin based.  This teaching strategy could then be paired with context clues, as context clues within the word itself.  This is most appropriate for scientific terms.  The idea is to break down the word to its most basic components and then decipher the word's meaning from there.
In the classroom, this could be an early semester unit for students, where they learn to break down biology into bio- life, and -ology - the study of.  This makes words like "photosynthesis" understandable for struggling readers

     This video provides an overview of cellular respiration and its basic steps.  It goes over the importance of ATP  (which is very necessary to life), and the function of the mitochondria.  It goes over glycolysis, the Kreb's Cycle and electron transport chain of respiration.  As it does this, it shows each different kind of molecule as a different cartoon.  The video also explains the relationship between cellular respiration and photosynthesis, how the two complement one another by creating a large circle.  Additionally, the video discusses fermentation, including why it's necessary and why it is not a long term solution for multicellular organisms. 

       This text is incredibly educational, with enough humor to be engaging without being distracting from the content.  The text of the video is simple enough that struggling readers should be able to keep up with the pace of the video while listening to the words.  However, the words involved are essential to science without using more jargon than needed.  For an ESL student, this video may prove to be a touch difficult, but the illustrations and animations paired with labels alone would be EXTREMELY helpful to students learning about cellular respiration.  This is a traditionally difficult concept of biology, and the visual cartoonish elements could be valuable if used consistantly.  If we had a lesson on an overview of cellular respiration, this video/text could be used to clarify components of the process.  Additionally, the cartoons could be used in notes to create more distinctions than alphabet soup.

 Santhi Soundararajan at the Asian Games, Doha
This  article tells the story of Indian Olympian Santhi Soundararajan, who failed her gender test after taking silver at the 2006 Olympics.  Officials revoked her medal.  The article does not say how she failed her test, but mentions the kinds of officials present from her test.  It should be kept in mind that this occured in 2006, and that general opinions and standards for gender have changed since then.   
This article and its accompanying case could provide a topic of debate about the various forms of sex detemination, and would give modern purpose to a lesson.  Methods of sex determination include anatomy, physiology, and karotyping of chromosomes. The lesson could lead off with a picture of the athlete.  What are students' first impressions of the athlete's gender?  Why?  
The article could then be introduced, and accompanied by a discussion of anatomical sex determination, followed by physiological determination.  At this point in the lesson, what would the students (in small groups, consitute as guidelines for being male?  for being female?).
We could use the case as a springboard and then begin to look at karotypes.  We may not have Soundararajan's, but this case introduces genetic conditions in which a person may not be blatantly one gender or another in terms of a molecular karotype.  Traditionally, the presence of a Y chromosome is the single indication (chromosomewise) of being male, but what about people with Turner Syndrome or XXY?  All of these are major concepts in biology, accompanied by modern topics and schools of thought in a time when gender identity is becoming more and more fluid.

      This poem dedicates a stanza to each of the organelles of the cell, for all of the basic organelles. 
The poem was written by a student. He/she uses a metaphor to describe each of the organelles in a way more familiar to a student due to the use of familiar rather than academic language.  This language also isn't of an incredibly high level, so students who struggle with literacy or English would have little to no difficulty comprehending the text. 
   This poem would be a wonderful review for students before a unit test on the cell.  It provides examples used in daily life, like a traffic light, or a vending machine, to explain the mechanisms of the cell.  I could read the poem to students, or hand out the poem to groups after deleting the word in each stanza that gives away the answer, and the students could attempt to guess which organelle pertains to which stanza.  The students could then write their own stanzas in small groups, and could read them aloud and give others a chance to guess which organelle is being described.  Students would then have several metaphors to choose from when studying for their test.  This text would also assist students who struggle with jargon, or the dense nature of scientific texts.

      I have found a Cell Theory Rap!  This rap covers the three compoenents of the cell theory, and explains the discovery of each point.  The names of the scientists involved are listed in each verse.  So the verse talking about Hooke explains the discovery of the cell by observation of a cork slice.  The video accompanying the song is also a lyric video, so there is no question as to what the man is saying within the song.  This also provides a visual for students who may struggle with English, so that they aren't forced to rely on auditory skills alone. 

    The Cell Theory Rap is terribly catchy.  I do not doubt that it'll be stuck in my head for a week or two, and my hope is that it'll have the same effect on my students.  The song could be placed within a lecture or PowerPoint as a brain break for the class,and then used as a point of reference for the remainder of the unit.  So if the song were to be played as an introduction, a particular verse could be replayed later.  So we could talk about Hooke, and then listen to his verse again.

This higher level text is about the applications of epigenetics in terms of diseases instead of offspring.  Specifically the text focuses on cancer, citing hypomethylation as encouraging tumor growth, while hypermethylation suppresses tumors.  These methylation patterns may be able to be tracked across the genome, giving people ideas on how to discourage cancerous growth.  
Within the classroom, this text is thought provoking.  Traditional epigenetics focuses on the future, what people do now that affects their future offspring.  This article could be used to expand student thinking beyond their paradigm.  Additionally, this is a hot topic in biology, and would be an interesting gateway to encouraging students to look into current topics in biology that interest them.

The Immortal Life of Henrietta Lacks 
This true story follows the life, death, and immortality of Henrietta Lacks, specifically her cells.  This black woman had cells taken from her (in the Jim Crow era) without knowledge, and the cells reproduced to such an extent that they were able to be used as a standard for research.  Scientists made money from the reproduction of Lacks' cells, and her impoverished family never saw a cent.
The ethical implications of this book are immense, and the story components are compelling, showing the full scope of what this woman went through in her time.  In the classroom, this book would present opportunities to create ongoing debates every week, as the ethical dilemmas unfold.  This would create ethical platforms in a modern time through the lense of the 50's.

This article explains photosynthesis.  It isn't an introductory material, but it does plainly explain how photosynthesis works.  The article also covers where photosynthesis occurs (specifically, not simply in the chloroplast).  The article also goes on to explain variations in photosynthesis, a topic not covered in detail by most textbooks.  The article talks about different kinds of CAM plants, and explains what chromatophores do within a bacteria.
This book could be used as a supplementary text with a photosyntheis unit.  The connections drawn at the end of the article are very useful for reminding students that not all photosynthesis is the same, and can link this knowledge all the way back to protists.  Additionally, as photosynthesis can be confusing, repition of the process in a variety of ways is often crucial to comprehension, making this article ideal for classroom use.

Osmosis Jones is an animated film about the adventures of Osmosis Jones, a leukocyte, within the body of Frank.  As a leukocyte, Jones is a cop within the body, and fights germs and bacteria.  However, Frank is not a healthy individual, and his poor diet and lack of excersise finally catch up with the man when a deadly virus invades his system.  Jones is the only one who believes the virus is real, and has 48 hours to stop him.  

While simple and humorous, Osmosis Jones creates a vivid imagery of the inner workings of the body, particuarly the nervous system and some of the immune responses.  Within a lesson the movie would serve as an interesting compare/contrast near the end of a unit during which students identify what has been correctly personified within the body, and what's scientifically inaccurate about the movie.
