The importance of mathematical problem solving (MPS) has been widely recognized. While there has been significant progress in developing and studying interventions to support teaching and learning MPS for students with disabilities, the research on how to accurately and effectively assess the impact of those interventions has lagged, leaving a gap in understanding whether interventions are truly achieving their intended outcomes. The purpose of this mixed-method study was to explore how a dynamic assessment (DA) approach can be used in the context of an evidence-based MPS intervention, Enhanced Anchored Instruction, as an alternative means of assessing the MPS of students with disabilities. Our findings suggest that DA is an adequate assessment tool and can provide additional information for teachers to better understand the MPS strengths and challenges of students with disabilities such as MPS ownership transition. Study limitations, considerations for future research, and implications for practice are discussed, emphasizing the importance of rigorous evaluation of the DA approach to improve teaching and learning MPS for students with disabilities.

Sex education is needed for improved mental and physical health and is a vital part of education for young people. However, sex education for students with intellectual and developmental disabilities is largely absent in China. We conducted a survey among 51 special education teachers who worked with students with intellectual and developmental disabilities to explore their knowledge level of sexual and reproductive health, as well as their beliefs and experiences regarding sex education. Results indicated a high knowledge level among teachers and a strong belief in the necessity of sex education. The scarcity of school-based sex education was also reflected in the experiences of special education teachers. The implications for breaking the silence around sex, developing comprehensive school-based sex education, and establishing teacher preparation and training systems in terms of sex education for students with intellectual and developmental disabilities are discussed.
