Which is a better solution for our non-English speaking students?
Two groups are pretested, exposed to a treatment (x), and post tested (o).
History: During allotted time there may be distractions, i.e. weather, phone in classroom, fire drills, etc.
Maturation: Students over time may lose interest or may be embarrassed to be in the group and not pay attention.
Testing/Pre-test Sensitization: Students can expect what will be on the post-test since there will be a pre-test to asses the students.
Instrumentation: Students might get bored of taking the surveys or parents might not fully understand what is being asked.
Mortality: Students might be absent or move away.
Differential Selection of Subjects: Each group is in a different school. One group will be given material in their native language and the other group will only be given English material.
A question that was given to parents on a survey:
From the previous Bar Graph we can see that the more a parent reads to their child in English the higher the pre-test score is. This is a good indication that immersing the student in English language has higher benefits than bi-lingual instruction.
Also, our correlation chart shows a high positive correlation. The Rxy is 0.94.
