The statistical population of the validation phase was 10 experts in the field of multimedia and consulting who judged the content and quality of the design using a researcher-made checklist based on the items of the Clear Communication Index tool. The statistical population of the third phase was parents and educators in Tehran city. Using available sampling method, 70 people were selected and randomly assigned to the two groups. The research tool was a researcher-made test of sexual education knowledge. The results of one-sample t-test showed that the children's sexual multimedia has the necessary validity according to experts (sig: 0.000, t: 23/319) and has a significant effect on the knowledge of parents and educators (T: 3.602, sig: 0.001).

Abstract
The aim of this study was to design and validate a questionnaire to assess learners' readiness who participate in Mooc courses. The method of this research is in terms of how to collect descriptive information of correlation type (factor analysis) and in terms of applied purposes. The statistical population of this research includes two categories: 1) Specialists and practitioners of E-learning and Mooc in the country.2) 200 people who have awared about Mooc-based course. Data was collected through the means of a Researcher-made questionnaire with reliability (α = 0.95) .In order to verify the validity of this tool two variables content validity coefficients (CVR) and validity index Content (CVI) was used and validated. Quantitative analysis methods such as exploratory and confirmatory factor analysis with the help of SPSS and LISREL software were used to analyze the data. The results of ten factors including: access to technology, technical skills, motivation and attitude to learning, ability to learn through media, self-awareness, self-efficacy, self-direction, social skills, communication and teamwork, critical thinking, self-criticism and constructive criticism, and analysis skills were analyzed in the questionnaire. The results showed that T-values were significant for each indicator with relevant factors with more than 99% confidence. This finding emphasizes that the markers support their agents well. Due to these cases, the necessary evidence was provided to confirm the validity of the items and factors. The fit indices all have a favorable and relatively favorable condition, which indicates the proper fit of the data with the model.

Abstract
The purpose of this research was to investigate the effect of applying a teaching methodology which integrated artificial intelligence Chabots on second language learners’ speaking skills, achievement motivation, and their attitude towards learning it as a second language. The statistical population of the study included 60 English language learners who studied at Salman Farsi University in Kazerun during the academic years of 2021-2023. The selected sample was randomly assigned into two experimental and control groups. The research method was an experimental method with a pre-test-post-test design with a control group. At first, the pre-test of the English language proficiency was administered to both groups, and then, for 15 weeks, the experimental group was taught with the integration method of the Alexa Chabot, which is an English conversational Chabot, and the control group was taught via the traditional teacher-textbook method during the same period. At the end of the training course, the post-test of speaking skills and the motivation questionnaire was administered to both groups. T-test and multiple variance analysis were used to analyze the data. The results of the data analysis showed that the teaching method with the integration of Chabot is effective in significantly improving learners’ speaking skills, achievement motivation, as well as the learners' attitude towards learning English. The results are discussed and suggestions for further research are made.
