## Experimental ResearchPresentation Transcript

• Experimental Research The higher frequency of Chinese Character writing can improve the result of the Dictation performance
• Experiment Research
• This is Experimental Research because the hypothesis is related to two variables, the number of Chinese Character writing and the result of Dictation .
• How could data for the variables be collected?
• Divided students into 3 groups. The numbers of Chinese Characters writing exercises before dictation is 2,3 and 4.
• Record (Before): Record the numbers of Chinese Characters writing between each dictation. The Chinese Characters Exercise is related to the dictation.
• Record (After): Record the dictation scores for each dictation.
• Continue to repeat these procedures throughout the whole semester.
• How could data for the variables be collected?
• Measurement: Collect all data and input into the Excel file.
• Statistical Calculation
• Calculate the Mean of each studentsâ€™ scores.
• Calculate the Mean of each group.
• Calculate the correlation coefficients between 2 variables [number of writing and the result].
• If r nearly to +1, 2 variable is highly related.
• E ducation Implication
• The r can show the relationship between the numbers of Chinese Characters writing exercises to the result of dictation.
• If r is high (larger than 0.5), teacher can provide more exercise to students to improve their dictation performance.
• If r is low (less than 05.), teacher may think students have other potential problem for dictation.
