Participants assigned to this arm will participate in the SEED self-instructional, web-based teacher training program designed to support autistic children and children with developmental delays.
Behavioral: SEED Online Self-Instructional Program
Participants in this arm will receive alternative educational materials (Kit for Kids) related to supporting autistic children and children with developmental delays during the study period. After comparison of post-intervention assessments, participants in this arm will be offered access to the SEED online program.
Behavioral: Comparison Educational Materials (Kit for Kids)
The SEED Online Self-Instructional Program is a web-based teacher training intervention designed to support the development of autistic children and children with developmental delays. The program consists of self-paced online modules covering child development, classroom management, and instructional strategies for inclusive education. Content is delivered through short instructional videos and web-based learning materials, and participants complete the program independently over a two-week period.
The comparison educational materials (Kit for Kids) consists of alternative instructional resources related to supporting autistic children and children with developmental delays. Participants assigned to this intervention review the provided materials during the study period as a comparison condition. These materials do not include the structured self-instructional online modules provided in the experimental intervention.
(Knowledge) Autism Knowledge Questionnaire-2 (ASK-Q-2) Total Score
The Autism Spectrum Knowledge Questionnaire (ASK-Q) is a 37-item questionnaire designed to assess knowledge and understanding of autism spectrum disorder (ASD). Each item is rated as "Agree" or "Disagree". Items are scored dichotomously (1 = correct response, 0 = incorrect response). Total scores are calculated by summing correct responses across all 37 items. Total scores range from 0 (lowest knowledge) to 37 (highest knowledge), with higher scores reflecting greater knowledge of autism spectrum disorder.
Time frame: Baseline (pre-intervention) and immediately after the intervention
(Knowledge) Participatory Autism Knowledge Measure (PAK-M) Total Score
The Participatory Autism Knowledge Measure (PAK-M) is a 56-item questionnaire designed to measure autism knowledge, neurodiversity-oriented beliefs, and perspectives informed by the lived experiences of autistic individuals. Each item is rated on a 7-point Likert scale, with 1 indicating "Strongly disagree" and 7 indicating "Strongly agree". After reverse-scoring negatively worded items, total scores are calculated by summing responses across all 56 items. Total scores range from 56 to 392, with higher scores indicating greater knowledge and more accurate understanding of autism and neurodiversity.
Time frame: Baseline (pre-intervention) and immediately after the intervention
(Knowledge) Survey for Educators' Empowerment for Diversity (SEED) Total Score
The Survey for Educators' Empowerment for Diversity (SEED) is a 68-item instrument developed by the research team to measure changes in knowledge related to autism and developmental delay following participation in the program. The instrument is organized around 13 core topics addressed in the program, with 5 to 7 items per topic, yielding a total of 68 items. Each item uses a dichotomous true-or-false response format. Responses are scored as 1 for correct answers and 0 for incorrect answers. Total scores are calculated by summing correct responses across all items. Total scores range from 0 to 68, with higher scores indicating greater knowledge and understanding of autism and developmental delay.
Time frame: Baseline (pre-intervention) and immediately after the intervention
(Attitude) Teacher Attitudes Toward Inclusion Scale (TATIS) Total Score
The Teacher Attitudes Toward Inclusion Scale (TATIS) is a 14-item self-report questionnaire designed to assess teachers' overall attitudes toward inclusive education. The scale evaluates beliefs about the inclusion of students with disabilities, perceived effectiveness of inclusive practices, and teachers' personal willingness and commitment to implementing inclusive classroom practices. Each item is rated on a 7-point Likert scale, with 1 indicating "Strongly disagree" and 7 indicating "Strongly agree". After reverse-scoring negatively worded items, total scores are calculated by summing responses across all 14 items. Total scores range from 14 to 98, with higher scores indicating more positive attitudes toward inclusive education and stronger support for the inclusion of students with disabilities in general education classrooms.
Time frame: Baseline (pre-intervention) and immediately after the intervention
(Attitude) Neurodiversity Attitudes Questionnaire (NDAQ) Total Score
The Neurodiversity Attitudes Questionnaire (NDAQ) is a 28-item self-report questionnaire designed to assess overall attitudes and perceptions toward neurodiversity. Each item is rated on a 5-point Likert scale, with 1 indicating "Strongly disagree" and 5 indicating "Strongly agree." After reverse-scoring negatively worded items, total scores are calculated by summing responses across all 28 items. Total scores range from 28 to 140, with higher scores indicating more positive attitudes toward neurodiversity and greater endorsement of neurodiversity-informed perspectives.
