This study explored components of language comprehension (vocabulary, grammar, and higher-level language) skills for poor comprehenders in French immersion. We identified three groups of bilingual comprehenders (poor, average, and good) based on English reading performance and compared their language comprehension skills in English L1 and French…

It is surprising that there are inconsistent findings of transitive inference (TI) in young infants given that non-linguistic species succeed on TI tests. To conclusively test for TI in infants, we developed a task within the social domain, with which infants are known to show sophistication. We familiarized 10- to 13-month-olds (M = 11.53 months)…

This paper reports on a study of 3rd-grade students' modeling with data, which involves comprehensive investigations that draw upon STEM-based concepts, contexts, and questions, and generate products supported by evidence and open to informal inferential thinking. Within a real-world STEM-based context of licorice manufacturing, students…

The quality of teachers is now a central focus of policy and research. In spite of this focus, two key gaps exist, and this dissertation helps to fill them: First, mediation models involving the study of the effects of teaching are rare; instead, most current investigations of teachers focus primarily on the effects of teachers, with less…

One of the highest ambitions in educational technology is the move towards personalized learning. To this end, computerized adaptive learning (CAL) systems are developed. A popular method to track the development of student ability and item difficulty, in CAL systems, is the Elo Rating System (ERS). The ERS allows for dynamic model parameters by…

Studies have shown that reading comprehension is the most difficult section of the Paper-Based Test (PBT) TOEFL. Therefore, this research aimed to identify which sub-skill in reading comprehension poses the greatest challenges for the students and how this sub-skill correlates to other reading comprehension sub-skills. To achieve this purpose,…

In 2013, a bivariate designed instrument of personality descriptors was given to a district school system to correlate difference between the teacher population and that of the administration. Results indicated a correlated population grouping where the two groups were similar in generalized personality constructs. Results indicate the leadership…

This article explores all the actions and opportunities school librarians take to reinforce reading instruction and reinforce learners' growing reading skills. It also details ways to enhance reading instruction through technology and makerspaces.

The authors propose an integrative theoretical model of reading called the direct and indirect effects model of reading (DIER) that builds on and extends several prominent theoretical models of reading. According to DIER, the following skills and knowledge are involved in reading comprehension: word reading, listening comprehension, text reading…

In policy evaluations, interest may focus on why a particular treatment works. One tool for understanding why treatments work is causal mediation analysis. In this essay, I focus on the assumptions needed to estimate mediation effects. I show that there is no "gold standard" method for the identification of causal mediation effects. In…

Statistical reasoning focuses on properties that belong not to individual data values but to the entire aggregate. We analyze students' statements from three different sources to explore possible building blocks of the idea of data as aggregate and speculate on how young students go about putting these ideas together. We identify four general…

Recently, MDS has been utilized to identify and evaluate cognitive ability latent profiles in a population. However, dimension coordinates do not carry any statistical properties. To cope with statistical incompetence of MDS, we investigated the common aspects of various studies utilizing bootstrapping, and provided an R function for its…

We describe how students can be encouraged to actively review course contents on inferential statistics by creating application-oriented exercises and sample solutions on the basis of concrete and realistic research articles and their data. For evaluation purposes, we use students' reactions to the activity and investigate its effects on the final…

We examined the Direct and Indirect Effects model of Writing (DIEW), using longitudinal data from Korean-speaking beginning writers. DIEW posits hierarchical structural relations among component skills (e.g., transcription skills, higher order cognitive skills, oral language, motivation/affect, background knowledge) where lower level skills are…

The study compared the use of the lexical glossing and inferencing strategies that impact toward the students' reading comprehension. The objective of the study was to find out the effective strategy to use for enhancing the students' reading comprehension. The population of the study was 40 Informatics Systems students of Potensi Utama…
