Knowledge surveys (KS) are a student self-assessment tool consisting of an ability statement for each learning objective in a course. Students respond by rating their confidence in performing a specified skill. Pre-unit KS transparently communicate learning objectives, alert faculty to self-assessed knowledge and skills students possess as they…

Autism spectrum disorder (ASD) and ASD symptoms are overrepresented among gender-diverse youth across studies. Gender-diverse and ASD youth are at risk for anxiety, but anxiety is unclear among gender-diverse youth with ASD. The Social Communication Questionnaire (SCQ) is a commonly used ASD screener, including in multidisciplinary…

This study examined the psychometric properties of the Positive and Negative Affect Schedule for Children-Short Form (PANAS-C-SF) in a diverse sample of 15-year-olds in the United States [N = 4382]. Multiple measurement models, including a one-factor model, two-factor orthogonal and oblique models, a three-factor model (PA, Fear, and Distress),…

The research aimed to achieve the following objectives: 1)Assess the effectiveness of cooperative learning management utilizing the STAD technique and KWDL technique among PrathomSuksa 6 students in solving decimal problems, with a target of achieving a 75/75 criterion, 2) Enhance the problem-solving abilities of grade 6 students in mathematics by…

Young children's language skills have a significant positive impact on their academic success throughout school, especially on reading and writing performance. The spread of COVID-19, which has resulted in lockdowns, fewer learning hours in kindergarten, and distance learning, might have affected children's exposure to learning opportunities. The…

Argumentation is fundamental to science education, both as a prominent feature of scientific reasoning and as an effective mode of learning--a perspective reflected in contemporary frameworks and standards. The successful implementation of argumentation in school science, however, requires a paradigm shift in science assessment from the…

In mathematics, there are four basic operations that students must master from the elementary school level, namely addition, subtraction, multiplication, and division. However, some students experience difficulties or misunderstandings in interpreting multiplication as repeated addition. This research aims to improve the learning outcomes of…

Purpose: The finite verb morphology composite (FVMC) is a valid measure for charting children's tense development and for differentiating children with and without language impairment during preschool and early elementary years. However, it is unclear whether FVMC scores vary as a function of language sample elicitation contexts. The current study…

This dissertation comprises three complementary studies that aim to advance the understanding and practice of Individualized Education Programs (IEP) and Present Levels of Academic Achievement and Functional Performance (PLAAFP) development in special education. In the first study, we systematically reviewed empirical research measuring IEP…

Sometimes a treatment, such as receiving a high school diploma, is assigned to students if their scores on two inputs (e.g., math and English test scores) are above established cutoffs. This forms a multidimensional regression discontinuity design (RDD) to analyze the effect of the educational treatment where there are two running variables…

While earning a high school diploma is a critical educational milestone for students, research has shown that obtaining a college degree further equalizes opportunities and increases their upward mobility. To be eligible to apply for the University of California system, students must take 15 college-preparatory courses during their high school…

Due to COVID-19 pandemic restrictions, new instructional designs for mathematics courses have recently been developed. Unlike traditional e-learning courses, distance learning via videoconferencing contains more synchronous elements and is therefore more closely related to classroom instruction. Since theories of person-environment fit suggest…

In the existing literature, scholars have proposed various indices to measure the lexical richness (LR) of English as a foreign language (EFL) writing. However, there are currently issues of redundant indices and inconsistent usage. Attempting to address the research question of which indices are the most sensitive and effective ones to…

This study was conducted in order to reveal the level of instructional leadership behavior scores of school administrators working in public secondary schools according to the opinions of teachers and to examine them in terms of various variables. The working group of this research, which was designed in the converging parallel pattern of the…

Although lexical diversity is often used as a measure of productive proficiency (e.g., as an aspect of lexical complexity) in SLA studies involving oral tasks, relatively little research has been conducted to support the reliability and/or validity of these indices in spoken contexts. Furthermore, SLA researchers commonly use indices of lexical…
