This simply means that from the perspective of the model, students taking Calculus I in different semesters, were not very different in ability except for those taking the course in term The predictive validity of selection measures used by the University of Petroleum and Minerals in Saudi Arabia, Dissertation Abstract Interna- tional, 47 2 Almost all these students have Arabic as their first language as well as it being the language of instruction during their matg schooling.

The best model seems to suggest that the academic subjects of the preparatory year are important predictors of Calculus I performance. Therefore, future research may possibly look into this factor to corroborate the result.

The added last analysis was conducted with only the academic variables in the model. Mathematics creativity as related to aptitude for achievements and attitude towards mathematics, Dissertation Abstract International, 42 1 Although neither ENGL nor term were significant by themselves, their joint effects with MATH matb that the prediction should be discounted by 0.

The reason for choosing Calculus I is because it is largely considered as the backbone of the calcu- lus series. Table 3 gives three of these models and variables therein. Chinese and English mathematics language: The relation between linguistic clarity and mathematics performance, Dissertation Abstract International, 59 7 The table also reports the models, the multiple correlation R- values, R2 -values, Adjusted R2 -values with associated degrees of freedom, F -values and p-values.

This effect represents the common knowledge and skills that are in the preparatory-year English curriculum as represented in both English courses that students carry into the context of semester term Log In Sign Up.

However, Model 3 is the best model and explains about 36 per cent of the total variance in the Calculus I grade. Our focus in this study is on students taking the Calculus I strand. Other factors that contributed significantly in the best model included some interaction of the preparatory-year courses.

In addition, we intend to investigate the effect of the semester in which students take Calculus I. The predictors of success of computer aided learning of pre- calculus algebra. A longitudinal study measuring the ability of two South African mathematics tests to predict mathematics performance of Grade 9 high school pupils, South African Journal of Education, 19 2— As can be noticed from Table 4, all three models are statistically significant at alpha 0. That is, for Termthe profile of Calculus I student performance is better explained by a gradient that is smaller than what is represented by MATH effects alone.

In addition to bridging the language barrier, the programme also aims at creating a matb atmosphere for a smooth transition from secondary school to university. The number of students that took Calculus I in all the seven terms are presented in Table 1. Those students posted to the college of sciences, engineering, and com- puter sciences are required to take a more rigorous mathematics strand which begins with Calculus Mtah, while others go for a different set of mathematics courses.

As noted earlier, surprisingly ENGL and MATH did not contribute sig- nificantly to the best model as stand-alone effects, but their joint effects with other variables can be readily seen as crucial predictors of success in the Calculus I course. Only the significant variables are reported here. This joint English knowledge and skills in term requires a higher predicted Calculus I score than in other terms beyond those already warranted by the ENGL effect. Contrast this with total variance explained by the best models 36 per cent.

Obviously I am a little biased, but I wholeheartedly agree with those statements. Summary of the contribution of preparatory-year courses in predicting Calcu- lus I performance.

One goal I have is for every student to find all useful resources to enhance their learning and build a solid base in mathematics that will help them in their future. Thirdly, the variables examined here are certainly not exhaustive and other factors such as student reading habits, level of motivation, etc.

For completion of the analyses, a regression model with only the academic vari- ables in the model was fitted with each of the variables in Table 6 added in last to see the effect of the course in question when other academic variables are already used as predictors of Calculus I performance.

On the other hand, the variable term is also not significant with the exception of term Enter the email address you signed up with and we’ll email you a reset link. This has shown that adding other variables including academic Term in the model add only around three per cent to the model. This interaction appears to subtract from the gradient of the regression line representing MATH at Term This result corroborates with many studies in the literature Begle, ; Tuli, ; Jamison, ; Kelly, ; Soares, ; Yushau, The implications of this finding for academic policy are discussed.

However, the Arabic language remains the main lan- guage of instruction at the primary and secondary levels.

Among the academic terms, semester appears to be the only significant term when compared to the reference term The first column of Table 5 is the name kfupj the variable, followed by degree of freedom, the estimate of the parameter, standard error, and the associated t-value, and p-value. On the other hand, the typical calculus sequence of courses is considered the nucleus of modern mathematics and vital for any science and engineering related courses, in which KFUPM specialises.

Bilingual instruction in college mathematics: Our web team has spent a lot of time trying to gather information that you will hopefully find useful. The number of students with these letter grades and corresponding numer- ical grades in the regression analyses are given in Table 2.

It is our hope that, due to ktupm of research in this area, the data presented in this study will serve as a starting point, and hopefully contribute to the field of mathematics education. The non-significant variables were reported in Table 3.

This should give some empirical support kath the new policy in the preparatory year that for a student to go to either an engineering or a computer-related course, he should get at least a passing grade of D in MATH and C in MATH as a placement requirement.

Most of them have had little English background at the time of admission. Although MATHwhich was crucial in Model 1 and 2, is surprisingly not significant in the best model, its joint effects with MATH appear significant as a predictor of Calculus I per- formance in the best model.
