Computer Software, Scaling Values, Scaling Methods, Unidimension, Performance Indicators, Teacher Evaluation, This study aimed to calculate average effect sizes for experimental and quasi-experimental studies of the effect of mathematics teaching methods on some emotional and psychological variables published in peer-reviewed Jordanian journals. The sample included (20) preliminary studies. Meta-analysis was used, and a coding model was developed that was verified for validity and reliability. The results showed that the average effect sizes of the primary studies varied. The results showed that the average overall effect size of the preliminary studies on the impact of teaching methods on some emotional and psychological variables is (1.438) and indicates a very large level of effect size, according to Cohen. The average effect size according to the secondary stage was large (1.554), and not significant for the university stage. It came at a huge level (1.925, 1.882) according to the sample size variable for the category (5 - 55) individuals, and the duration of the study for the period (more than a month and less than a semester), respectively. Based on the results, the researchers recommend conducting more mathematics education studies on gifted students, private schools, the university level, and the preparatory stage, including emotional and psychological variables.Abstract
The objective of this study was to develop statistical software, which the researchers themselves devised and programmed under the name "WINSCAL." This computer software utilizes unidimensional scaling methods to estimate the scaling values of stimuli and individuals. The researchers used the Microsoft Visual FoxPro programming language to create the software. There are also instructions on how to use the software in a study that looks at the effects of three different ways of scaling performance indicators in the classroom observation tool based on how important they are to educational administrators in the Directorates of Education in Irbid Governorate. The research employed both a descriptive and analytic methodology. The main goal of the WINSCAL software was accomplished through the implementation of thirteen unidimensional scaling methods. The application operated efficiently across multiple Windows operating systems and featured a straightforward graphical user interface and a sizable storage capacity. It was found that the results of this program's analysis of the scaling values of stimuli and individuals are an exact match to the results of sample analyses of research and previous studies that used data that hadn't been processed. The findings of the study, which were obtained from a sample of 86 male and female educational supervisors in the governorate of Irbid, revealed that the most important performance indicator in the field of learning and teaching in the classroom observation tool was (The teacher connects learning to life" and that the indicator (the teacher effectively implements the planned activities in classroom instruction) was the least important of the three scali. According to the WINSCAL program's research, the ranking of the other indicators varies depending on the method of data collection
