Description
Students with autism spectrum disorders (ASD) are increasingly included in general education and are expected to access core content, including science. Development of science content knowledge, scientific literacy, and scientific thinking are areas emphasized in legislation as well as the National Science Education Standards (NSES) as critical for all students. However, participation in science inquiry and discourse is often challenging for students with ASD given their difficulties with communication. Moreover, evidence on teaching academic content, such as science, to students with disabilities is limited. This comprehensive literature review synthesized ten studies of science intervention strategies for students with ASD. Findings suggest that students struggle with obtaining and retaining the background knowledge and strenuous vocabulary necessary to be successful with science content. Though studies related to instructional interventions in science for students with ASD are limited, these students can benefit from direct instruction through the implementation of supplementary materials such as e-texts, graphic organizers, and scripted lessons. Although there is not much research that supports inquiry-based practices, these interventions engage and assist students in the science curriculum by providing hands-on explorations with the material. Evidence-based practices for interventions in science for students with ASD have focused on direct instruction and inquiry-based practices. Direct instruction elicits explicit strategies in delivering science content concretely and directly. Many direct instruction approaches deal with the incorporation of visual supports and supplementary material to guide in student retention and access of complex ideas and terminology. Through direct instruction, the teacher facilitates and leads instruction to benefit the acquisition of science background knowledge. Contrastingly, inquiry-based practices encourage independent learning and hands-on explorations. While science is frequently inquiry-based in the general education setting, the communication challenges for students with ASD may contribute to difficulties with interactions and collaborations among peers within an inquiry lesson. Future implications include the need for additional, empirically-supported interventions in science for students with ASD and the need to target more inquiry-based science interventions for this population.

Description
This study explores parent satisfaction with their child's education based on teacher training and teacher credentials regarding Autism Spectrum Disorder (ASD). The study seeks to answer four questions about the relationship between parent satisfaction and a variety of factors concerning school type and teacher credentials. To investigate these questions, the researcher analyzed data from parent questionnaires and teacher questionnaires.

Description
This pilot study evaluated whether Story Champs and Puente de Cuentos helped bilingual preschoolers increase their usage of emotional terms and ability to tell stories. Participants in this study included 10 Spanish-English bilingual preschoolers. Intervention was conducted in 9 sessions over 3 days using the Test of Narrative Retell to measure results. Results did not find significant gains in either emotional term usage or ability to tell stories, but the results were promising as a pilot study.

Description
The present study investigated the communicative characteristics of challenging behavior documented in children with Autism Spectrum Disorder (ASD), and how those behaviors changed as receptive and expressive language skills changed. Several years of the individual education plans (IEPs), behavior plans, and test scores of three male students from a small non- public school (NPS) were reviewed for this study. Challenging behaviors that served a communicative function showed some signs of diminishing as functional communication increased. While functional communication did show signs of increasing with the acquisition of expressive and receptive language the participants differed in their dependence on prompting to use functional communication in lieu of challenging behavior. Additionally, some of the challenging behaviors were rooted in a difficulty with self-regulation and stimming behavior and didn't appear to serve a communicative function. Given the significant impact challenging behaviors have on the quality life of the children with ASD and their families, more research is needed to better understand the connection between spontaneous and independent functional communication and duration to independent attention to task effects on challenging behavior.

Description
Individuals with autism spectrum disorder (ASD) are known to show impairments in various domains of executive function (EF) such as behavioral flexibility or inhibitory control. Research suggests that EF impairment in adults with ASD may relate to ASD core symptoms, restrictive behaviors and social communication deficits. Mindfulness-based stress reduction (MBSR) has shown promise for improving EF abilities in neurotypical adults, but research has not explored its efficacy or neural mechanisms in adults with ASD. This pilot study examines the effects of an 8-week MBSR intervention on self-report measures of EF and resting-state functional connectivity in a sample of adults with ASD. Fifty-four participants were assigned either to an MBSR group (n = 29) or a social support group (n = 25). Executive function was measured using the BRIEF-2 before and after the intervention for the twenty-seven participants in the second cohort. MBSR-specific improvements in EF were found for BRIEF measures of initiation, inhibition, and working-memory. Resting-state fMRI data was analyzed using independent component analysis (ICA), and group by time resting-state functional connectivity differences were observed between the cerebellar network and frontal regions including the right frontal pole (rFP), medial frontal cortex (MFC) and left and right superior frontal gyri (SFG). The MBSR group showed increases in functional connectivity between the cerebellum and EF regions which correlated with improvements in BRIEF-2 measures. These findings suggest that MBSR may improve EF domains in adults with ASD, and that increases in functional connectivity between the cerebellum and frontal regions while at rest may be a mechanism for such improvements.
