Early detection and intervention for infants at risk of autism spectrum disorders

Autism is a developmental disorder that is characterized by abnonnal social interactions and communications as well as repetitive and restricted activities and interests. There is evidence of a genetic component, as 5% of younger siblings are diagnosed if their older sibling has been diagnosed. Autism is generally not diagnosed until age 3 at the earliest, yet it has been shown that early intervention for children with autism can greatly increase their functioning. Because of this, it is important that symptoms of autism are identified as early as possible so that diagnosis can occur as soon as possible to allow these children the earliest intervention. This thesis was divided into two parts. The first looked at the psychometrics of two proposed measures, the Parent Observation Checklist (POC), administered monthly, and the Infant Behavior Summary Evaluation (mSE), administered bimonthly, to see if they can be used with the infant population to identify autistic symptoms in infants who are at high risk for autism or related problems because they have an older sibling with autism. Study 1 reported acceptable psychometric properties of both the POC and IBSE in terms of test-retest reliability, internal consistency, construct validity and predictive validity. These results provide preliminary evidence that parent report measures can help to detect early symptoms of ASD in infants. The POC was shown to differentiate infants who were diagnosed from a matched group that was not diagnosed by 3 years of age. The second part of this thesis involved a telephone interview of parents who reported developmental and/or behavior problems in their high-risk infants that may be early signs of Autism Spectrum Disorder (ASD). During the interview, a service questionnaire was administered to see what interventions (including strategies recommended by the researchers) their at risk infants and affected older siblings were receiving, how satisfied the parents were with them and how effective they felt the interventions were. 3 Study 2 also yielded promising results. Parents utilized a variety of services for at risk infants and children with ASD. The interventions included empirically validated early intervention (e.g., ABA) to non-empirically validated treatments (e.g., diet therapy). The large number of nonempirically validated treatments parents used was surprising, yet parents reported being involved and satisfied, and thought that the services were effective. Parents' perceptions of their stress levels went down slightly and feelings of competence rose when they accessed services for their infants. Overall, the results of this thesis provide new evidence that parent-report methods hold promise as early detection instruments for ASD in at-risk infants. More research is needed to further validate these instruments as well as to understand the variables related to the parents' choice of early intervention for their at risk and affected children.

Changes in education and student-centred learning as related to senior secondary school English

The main purpose of this thesis is to t r ace broadly the educational changes in the past two decades showing a shift of emphasis from a teacher-directed, content-centred philosophy of teaching to a self-directed, student-centred mode of learning. The major justification for an Independent or an Individualized Learning programme with emphasis on "the response to literature approach" is 2 to produce the independent learner. Comprehensive r eading and t he use of t he ERIC system reveal widespread educational thought and practice related t o Individualization and Independent Study as a really democratic way of learning with freedom, independence and responsibility.

Conduct Disorder: A Handbook for Elementary School Educators

This research project examined the behavioural, social, and emotional issues affecting children and youth with conduct disorder. Based on the literature review, the deconstruction of theoretical and empirical studies, and findings from the needs assessment, Conduct Disorder: A Handbook for Elementary School Educators was created. This handbook was developed based on the evidence that conduct problems can most effectively be improved when multiple systems are included in the prevention and intervention of the disorder. Educators, related service providers, and the child all play an important role in designing and implementing effective interventions. Therefore, it is imperative to provide educators with the information necessary to begin this emerging collaborative process. The handbook was created as a tool for educators intending to enhance their knowledge when working with students with conduct disorder. A Needs Assessment was conducted to determine what educators wanted the handbook to contain to assist them in working with students displaying conduct problems. The educators evaluated the handbook, providing constructive feedback and confirming the potential value and practicality of this handbook for elementary school educators. The educators reported an increase in their understanding of conduct disorder, as well as a heightened awareness of the causal factors that contribute to the disorder. The list of community resources and agencies was thought to be a good starting point for educators looking for supplementary aids. The educators indicated that the handbook is a good reference tool to use when teaching students with conduct problems. The educators concluded with the hope that this handbook will be shared with others.

Helping Youth Venture Into Volunteerism: A Resource for Ontario Secondary School Educators

This study sought to create a curriculum resource for Ontario secondary school educators that addresses the inadequate preparation of students prior to their involvement in community service. Specifically, Helping Youth Venture Into Volunteerism: A Resource for Ontario Secondary School Educators was designed to help grade 10 Civics and Citizenship teachers prepare students for the 40 hours of community service that are a prerequisite for the Ontario Secondary School Diploma. The resource discusses problems with the current unstructured program, outlines researchers’ recommendations to address such problems, and provides comprehensive unit and lesson plans to help educators meet curriculum expectations for grade 10 Civics and Citizenship. In addition, the study examined the rationale and development of the community service program and reviewed related literature corresponding both to Ontario’s community service program as well as service-learning programs in schools. Study results and the accompanying resource will help improve the community service program’s effectiveness by integrating it into school practices and curriculum and making it more relevant, structured, and meaningful to students. By improving the community service program, students will be more engaged in community service and more likely will become lifelong volunteers and active members of their community.
