The current study aimed to investigate the effect of using the flipped classroom instructional method on students’ academic achievement compared to the traditional instructional method.  The data were collected from (52) undergraduate male and female students enrolled in a course in database management at a Jordanian public university.  The results of two-way ANOVA revealed a statistical significance main effect on students’ overall achievement due to the flipped classroom instructional method.  The results of two-way ANCOVA also revealed a statistical significance main effect on students’ overall achievement due to the flipped classroom instructional method after controlling for each of the student’s GPA, and the student’s average interaction covariates.

The current study aimed to develop, and examine the psychometric properties of, an Arabized Jordanian version of the Big Three Perfectionism Scale (BTPS) which consists of 45 items distributed on 10 first-order factors ("facets") and three higher-order factors (i.e., rigid perfectionism, self-critical perfectionism, and narcissistic perfectionism). Data were collected from 926 undergraduate male and female students studying at a public Jordanian university. First-order Exploratory Factor Analysis (EFA) revealed 10 facets. Three higherorder factors could be retained when the data were subjected to second-order EFA. The findings were in line with the hypothesis stating that perfectionism is a multidimensional rather than a unidimensional construct. The findings also indicated high facet and factor-level internal consistency coefficients. Overall, the findings provided support for the psychometric properties of the newly developed Arabized Jordanian version of the BTPS.
