Data preparation (also called "wrangling" or "cleaning") -- the evaluation and manipulation of data prior to formal analysis -- is often dismissed as a precursor to meaningful engagement with a dataset. Here, we re-envision data preparation in light of calls to prepare students for a data-rich world. Traditionally, curricular…

This dissertation project explores the potential for using an inferential statistics test (t-tests) within an existing writing program assessment design. The purpose of using inferential statistics is to provide several perspectives on a data set collected using the existing assessment design thereby improving what a writing program administrator…

Recent advancements in testing differential item functioning (DIF) have greatly relaxed restrictions made by the conventional multiple group item response theory (IRT) model with respect to the number of grouping variables and the assumption of predefined DIF-free anchor items. The application of the L[subscript 1] penalty in DIF detection has…

Research Context: In educational research, "context effects" are often of inferential interest to researchers as well as of evaluative interest to policymakers. While student education outcomes likely depend on individual-level influences like individual academic achievement, school contexts may also make a difference. Such questions are…

This article provides an overview of different computational options for inference following normal theory maximum likelihood (ML) estimation in structural equation modeling (SEM) with incomplete normal and nonnormal data. Complete data are covered as a special case. These computational options include whether the information matrix is observed or…

Little evidence is available regarding the differential impact of reading versus reading and writing on multiple source comprehension. The present study aims to: (1) compare the inferential comprehension performance of students in reading versus reading/synthesis conditions; (2) explore the impact of performing the tasks on paper versus on screen…

An ongoing debate in the literature on human reasoning concerns whether or not the logical status (valid vs. invalid) of an argument can be intuitively detected. The finding that conclusions of logically valid inferences are liked more compared to conclusions of logically invalid ones--called the logic-liking effect--is one of the most prominent…

Background: Generalisation inferences let readers identify a conceptually superordinate statement to represent multiple subordinate concepts. This study measures text genres' influence on the scope and timing of generalisation inferences. Methods: To measure the scope, or breadth, of generalisation inferences, undergraduates (N = 266) read…

Identifying the mistakes in student responses and being able to manage the solution process are among the fundamental skills that should be acquired by the pre-service teachers. This skill is important in probability, about which students have a great number of misconceptions. The aim of this study was to determine the misconceptions in the…

This quantitative study endeavored to compare a new strategy of making irrelevant information less salient with a common reading strategy of highlighting to determine which would best aid students in making connections within and between multiple texts. Participants were 60 high school students, ranging in age from 14-17 years old. The adolescents…

Data Analytics has grown dramatically in importance and in the level of business deployments in recent years. It is used across most functional areas and applications, some of the latter including market campaigns, detecting fraud, determining credit, identifying assembly line defects, health services and many others. Indeed, the realm of…

Generating accurate inferences is crucial for the successful comprehension of text and is a skill that needs to be supported starting in the early grades. Teachers can support inference-making during read-aloud lessons by asking inferential questions and providing scaffolding and feedback on students' inference-making. In this article, we describe…

Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

The aim of this article is to propose a didactical approach to establish appropriate relations between different kinds of chemical knowledge and explanations at the macro and the submicro level. Incorrectly moving between these two levels is regarded as the cause of many misconceptions in school chemistry, and several theoretical frameworks have…
