Mathematics physics is a difficult learning and becomes a scourge in studies in physics education. Learning physics and mathematics itself will be very effective when using e-modules, but in terms of making e-modules, students' opinions or perceptions are needed regarding this matter. This study aims to look at student perceptions and also compare these perceptions with other classes based on gender or gender. The research conducted is a survey type quantitative research. The sampling technique used in this study was simple random sampling with the research subject as many as 92 physics education students who contracted the mathematics physics course. The instrument used in collecting data is 15 questions containing 4 choices that must be filled out by students. Analysis of the data used in this study in the form of descriptive analysis and ANOVA test to determine whether there is an average difference in each student's perception. The results obtained indicate that girls have different perceptions in class A and class B, while for boys there is a difference between class A and class C. These results indicate that girls have a fairly large average difference in perception with each other, while for boys the perception tends to be uniform compared to girls.

This study aims to determine the effect of variable vocabulary and reading comprehension skills of argument essay writing. Method used is the method of survey with a sample of students of 40 students were taken by random sampling technique from Tunas High School Jaka Sampurna in Bekasi. Data collection using the validated test instrument. Regression equation Y ̂=1,079+0,385X_1 wich means that if the students vocabulary mastery is ignoed, then the ability to write arguments for 1,079. Every adding one point to the vocabulary it will add the ability to write the argument of 0,385 point. Regression equation Y ̂=1,079+0,355X_2 whic means that if reading comprehension is ignored, then the argument of 1,079 skill writing, meaning the reading comprehension is ignored then the ability to write arguments. For each additional 1,079 points in reading comprehension, reading comprehension will add 0,353 points. It can be concluden that the vocabulary and reading comprehension together affect 23,4% of the writing skills of argumentation percent of the value. (koef determinate R2 = 0,234 with the value of the test F = 5,665.
