Measuring the environmental awareness by using Schahn scale in its third amended "issue on a sample of Tishreen University students"

The aim of current research is to measuring the environmental awareness of Tishreen University students, by using the "Environmental Awareness Scale" which had been prepared by "Schahn" in its amended third form (1999) after being standardized on the Syrian environment. The research aimed to identify the differences in the degrees of environmental awareness among members of the research sample according to each of the following variables: Faculty type (theoretical-practical), gender (males-females), and the academic year. This research was conducted on a sample of (850) students (males-females) in the University of Tishreen to extract the psychometric properties of the scale and to check the significance of validity and reliability. The researchers used arbitrators' sincerity, honesty, and internal consistency to verify the veracity of scale's statements. Reliability was verified through consistency and repeated reliability, by using Cronbach's Alpha equation by split-half. The results found out that the values of honesty and reliability coefficients were high and statistically significant and demonstrated the validity of the scale. It was also showed there were statistically significant differences in the level of environmental awareness among male and female students. While no clear differences were shown among students that were related to the college type and school year variables.

Psychometric properties of the Adult Edition of Toulouse Self-Esteem Scale (A Field Study in the City of Lattakia)

This study aims to extract the psychometric properties of the adult edition of Toulouse self-esteem scale. The scale was translated from French to Arabic and it was introduced to a set of Arabic language specialists to ensure good paraphrasing, and then it was re-translated to the original language (French) to ensure the accuracy of the translation. The Scale was implemented on a random sample consisting of 500 adults in Latakia city. The study results indicate a high level of validity of the scale and high degree scale of reliability identical with the statistical indicators to of the French version of the scale. Subsequently a series of hypotheses was tested which showed that there was no difference between male and female means degrees on the scale except the social self field. Also, it was found that there are statistical differences by educational level of respondents in favor of postgraduate and graduate degrees. The differences on scale dimensions according to the taxonomic variables (gender and educational level) were studied too. The research suggested further studies on the scale in different environments and the necessity to be used in educational and psychological fields.

Psychometric properties of Toulouse Self-Esteem Scale- Adolescent Edition "A Field Study in the City of Lattakia"

This study aims to extract the psychometric properties of the Adolescent edition of Toulouse self-esteem scale. The scale was translated from French to Arabic and it was introduced to a set of Arabic language specialists to ensure good paraphrasing, and then it was back-translated to the original language (the French) to ensure the accuracy of the translation. The Scale was implemented on a random sample consisting of 466 adolescents in Lattakia city. The study results indicate a high level of validity of the scale and high degree scale of reliability identical with the statistical indicators to of the French version of the scale. Subsequently, hypothesis were tested to check whether there is a difference between male and female scores on the scale. Differences in the dimension of the social self were found. The research concluded to suggest the need for further studies on the scale in different environments and the need of using it in educational and psychological fields.

Indicators of Validity and Reliability of the Arab Image of the Toulouse Self-Esteem Scale - Children's Copy - in the Syrian Environment

The present study aimed to extract the Indicators of Validity and Reliability of the Toulouse Self-Esteem Scale - Children's Copy. The Scale was translated from French to Arabic and presented to a group of Arabic language specialists to ensure that the wording is correct, after which a counter-translation into the original language (French) was performed to ensure the accuracy of the translation. The scale was applied to a random sample of 413 children in Lattakia. The results of the study showed a high level of accuracy with a high degree of stability (repeatability of 0.776 and alpha-cronbach 0.81 ), identical to the statistical indicators of the Scale in its French version. A hypothesis was then tested as to whether there was a difference between the average male and female scores on the scale. It was found that there was a difference on the macro scale, the dimensions of social self-sufficiency and school self-interest for females. And 71.4% of individuals are at the high level of self-esteem. The research concluded that more studies on the scale should be carried out in different settings and should be used in the fields of education and psychology

The Effect of Both the Size and The Type of Statistical Sampling on The Estimates of Simple Linear Regression Equation Coefficients

These papers aim to study the estimation of the simple linear regression equation coefficients using the least square method at different sample sizes and different sampling methods. And so on, the main goal of this research is to try to determine the optimum size and the best sampling method for these coefficients. We used experimental data for a population consist of 2000 students from different schools all over the country. We had changed the sample size each time and calculate the coefficients and then compare these coefficients for different sample sizes with their coefficients of the real population; and the results have been shown that the estimation of the linear regression equation coefficients are close from the real values of the coefficients of the regression line equation for the population when the sample size closes the value (325). As it turns out that the Stratified random sampling with proportional distribution with class sizes gives the best and most accurate results to estimate linear regression equation with least square method.
