According to sociocultural theory, dynamic assessment (DA) merges instruction and assessment. This study attempted to compare the effects of interactionist versus interventionist DA on the writing fluency and complexity of adult versus young IELTS candidates in an international language school in Tehran with the age range of 15-48. One hundred and forty students (90 males and 50 females) who had enrolled in the IELTS preparation course in the spring of 2021 participated in this study. The study participants were divided into four groups namely, young interactionist, young interventionist, adult interactionist, and adult interventionist. The participants in all groups were homogenized based on the result of their performance in a standard version of Preliminary English Test (PET). During the eight-week treatment period, the interactionist groups were given writing tests followed by the instructor’s feedback and guidance, while the interventionist groups received instructions and were given writing test samples without qualitative feedback. The pre-test and post-test comparisons among the four groups by Two Way ANCOVA showed that both young and adult individuals in the interactionist groups had a significant improvement in their writing performance compared to those in the interventionist group. In addition, the study revealed the significant impact of interactionist DA vs. interventionist DA on both young and adult participants' scores in both writing fluency and complexity post-test. Likewise, the results showed no statistically significant interaction between the type of assessment and the candidates’ age. The study presents pedagogical implications for teachers, students, and IELTS preparation program designers.

The present study explained the role and responsibility of parents and schools in the sexual education of children through library studies and qualitative-descriptive research methods in this field. Child sexual education requires parents to know when, what and how to pass it on to their child. Some parents think that it is better to keep the child away from any sexual issues so that sexual thoughts do not develop in their minds, but sexual questions inevitably arise in the minds of children and the ignorance of parents and their inability to answer some questions of children cause children to get confused about sexual issues. Therefore, the most important issue for them is to grow up in a safe environment physically, mentally and emotionally. In the meantime, due to the prevalence of abnormalities and widespread factors that make sexual deviations more and more widespread, it is the suitable implementation of sexual education methods that requires children to be raised in a healthy environment based on religious supervision and education. Employing such methods also guide their sexual instincts in the right direction, and protect them from all kinds of abnormalities such as masturbation, thirst, oral and verbal sexual abuse, prostitution and pornography that lead to sexual perversion and harm.
