  1. 1. Vocabulary Strategies to Improve SAT Scores Leonardtown High School Christine Chadwick, Stefanie Glorioso, Daniel Morris, Marc Pirner
  2. 2. JustificationSIP: Improve SAT scores- “Offer the entireschool testing skills and vocabulary words” 35 Strategies for developing Content Area Vocabulary by “Content area achievement depends closely on students’ mastery of specialized vocabulary”Our Strategy: Semantic Mapping
  3. 3. Content Area Examples• English- students write the way they talk (or text), emphasis on vocabulary to help overall academic English• English- explicit academic vocabulary instruction is not being observed in some classes• Government- there are many words and concepts that are specific to government that are fundamental to learning / high performance in social studies• Chemistry- there are many vocabulary words that are highly specific to chemistry that are need to be successful in the sciences
  4. 4. Problem and Population• Students could improve their verbal SAT scores and content area achievement with more explicit vocabulary instruction.• Population: • Honors Chemistry • English 11 and 12 Standard and CM • Government 10 CM
  5. 5. Semantic Map• Structured word map• write the vocabulary word in the center • connect words that are synonyms, antonyms, definitions, examples, parts of speech etc.• Gives students • context rather than dictionary definition • usage rather than memorization• more vocabulary• Example of student work
  6. 6. Benefits of Strategy• Allows for a visual/spatial representation of vocabulary• Students see the relationships between concepts and vocabulary• Requires higher order thinking skills• Can help activate prior knowledge
  7. 7. Research questions• Affective Question: • Do the students feel comfortable using content area vocabulary?• General Questions: • Are the students using the vocabulary? • Are students’ vocabulary scores rising?
  8. 8. Data collection plan Pre-post Tests Observation Student Work Do students feelcomfortable using X X X content vocabulary?Are the students using the X X X vocabulary? Are vocabulary X X X scores rising?
  9. 9. Pre-post Assessment I• Half of the questions on the pre-post assessment will look like the following question: • (Vocabulary Word) • A. I have never encounter this word before. • B. I have seen this word before. • C. I can define this word. • D. I have used this word before• Other half to check student understanding of each vocabulary word.
  10. 10. Pre-post Assessment II• 10 vocabulary words• Words will be used in context• Students will determine whether the word is used correctly• Selected response format• Post assessment- vocabulary quiz
  11. 11. Observation guidelines• Specific items to observe: • If the students used vocabulary words • When and how often students use vocabulary words in speech and writing • Tally of how many times students use vocabulary words• Questions to think about during observation: • Do students hesitate when attempting to use vocabulary words?
  12. 12. Timeline• Each group member will complete every step on the decided day in their respective classrooms. • October 18: pre-test 1 will be given with the vocabulary for the week. • October 22: post-test 1 will be given for the same vocabulary. • October 25: pre-test 2 given with vocabulary for the week. • Week of October 26: strategy implemented • October 29: post-test 2 will be given for the same vocabulary • November 8 and 9: analyze data
  13. 13. English 11 Results Quantitative Data• Vocabulary words • Student view on used correctly vocabulary knowledge• Pre-post 1: p=1.846E-12 • Pre-post 3: p=3.787E-23 Significant Significant• Pre-post 2: p=0.308 • Pre-post 4: p=3.376E-16 Not Significant Significant• Post-post 1: p=3.153E-11 • Post-Post 2: p=6.182E-5 Significant Significant • The semantic maps • Semantic maps made a made a significant significant difference in difference in increasing increasing student self view vocabulary scores. of vocabulary knowledge
  14. 14. English 12 Results Quantitative Data• Vocabulary words used correctly • Student view of vocabulary use• Pre-post 1: p=0.102 • Pre-post 1: p= 3.16x10^- Not Significant 5 Significant• Pre-post 2: p=2.37x10^- • Pre-post 2: p=1.28x10^- 4 Significant 10 Significant• Post-post 1: p=0.0516 • Post-post 1: p=8.51x10^- Not Significant 3 Significant • The semantic maps • The semantic maps made a significant made a significant difference in difference in increasing increasing vocabulary vocabulary scores. scores.
  15. 15. Chemistry Honors Results• Vocabulary Words Correctly Used • Pre test 1: Post test 1 Ttest p.= 2.03x10-6 • This shows that the students made significant improvements on their knowledge of the vocabulary words from the pre test to the post test. • Pretest 2: Post test 2 Ttest p.= 8.95x10-13 • This shows that the students made significant improvements on their knowledge of the vocabulary words from the pre test to the post test. • Post test 1: Post test 2 Ttest p.= 0.0769 • There is no statistical significant difference between the two post tests, but is approaching significance..
  16. 16. Chemistry Honors Results• Student View on Vocabulary Knowledge • Pre-test 1: Post test 1 Ttest p.= 3.55x10-9 • This shows that the students made significant improvements in their knowledge of the vocabulary words from the pre test to the post test. • Pre-test 2: Post-test 2 Ttest p.= 1.37x10-16 • This shows that the students made significant improvements in their knowledge of the vocabulary words from the pre test to the post test. • Post test 1: Post test 2 Ttest p.= 0.0215 • This shows that the students felt they knew the words more after they did the semantic maps than when they did not use any type of formal strategy.
  17. 17. Experiment Variation• With this variation of the experiment, the same test was given 3 different times:• Pre-test- first time they see the test• Post-test – second time- still no intervention• Final- third time after semantic mapping• Data is compared between pre-post, pre-final, and post- final to determine whether or not the intervention was successful
  18. 18. Government Results• Vocabulary words used correctly• Pre-post: p= 0.341761 • Students view on Not significant vocabulary knowledgePre-post: p=• Pre-final: p= 0.000149 0.003989 SignificantPre-final: p= Significant 1.34406E-12 Significant Post-final: p= 2.80948E-07• Post-final: p=4.75131E-05 SignificantThe semantic Significant mapping technique made a significant difference in• The semantic mapping increasing student comfort with technique made a vocabulary. significant difference in increasing vocabulary scores.
  19. 19. Findings from observations• Few observations were made: • rarely using vocabulary words in English or Government class • used more in practice in Chemistry • used when explicitly asked to• Students recognized words when used by others
  20. 20. Overall Findings• Vocabulary scores increased from Post 1 to Post 2• Student view of vocabulary use increased• Rare student use of vocabulary words in the classroom setting, more confidence and use in Chemistry• Recognition of vocabulary words when used
  21. 21. Answers to research questions• Are the students using the vocabulary?• Students use vocabulary rarely• Students reported using vocabulary words more often after the implementation of semantic mapping• Therefore- semantic mapping increases student use of vocabulary words
  22. 22. Answers to research questions• Are students’ vocabulary scores rising?• Yes, scores are rising in English and Government, but not in Chemistry • could be due to a lack of vocabulary routine in Chemistry.
  23. 23. Discussion• This strategy yielded overall positive results although reimplementation would help to provide more reliable results• Reasons data could be flawed: • Faulty selected response questions • Strategies were not implemented identically in all classrooms, nor did they follow a specific procedure • difficulty of vocabulary words varied across data sets • Timing of the tests • Deviation from observation guidelines• Too many words in a short amount of time for Chemistry
  24. 24. Next steps?• Implications for Future Research: – strategy should be implemented identically across all content areas – use fewer vocabulary words of relatively equal difficulty – could be broken into two separate studies –One study on vocabulary scores –specify use as a study tool –One study on student view on vocabulary use
  25. 25. Back to the big picture• Semantic mapping is one of many study tools• Students need to learn about different study tools • encouraged to use other visuals as study tools to study for the SAT.
