To address the disconnect and bridge the gap between mathematics and science education, we developed interdisciplinary lessons and real-world applications by integrating Algebra 1 and Biology in a collaborative cohort model. We aim to improve student engagement, knowledge transfer, and performance on assessments in both disciplines. The…

This study aimed to profile the sublexical, lexical, and text level language skills, and cognitive processes of a sub-group of children with poor reading comprehension known as poor comprehenders. An assessment protocol was developed to assess each of the components from Perfetti and Stafura's Reading Systems Framework. A comprehensive profile was…

Purpose: This paper aims to examine whether multiple choice questions (MCQs) can be answered correctly without knowing the answer and whether constructed response questions (CRQs) offer more reliable assessment. Design/methodology/approach: The paper presents a critical review of existing research on MCQs, then reports on an experimental study…

This Study Snapshot highlights key findings from a study that examines full-day kindergarten (FDK) implementation in Oregon. The evidence base on FDK is generally positive for short-term effects and unclear for longer-term effects, with some prior research associating FDK with gains in student outcomes such as grade 3 math and reading standardized…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

The measurement tool not measuring the specific construct has a validity problem. Individuals based on the results obtained from this type of tool should not be evaluated. The purpose of this study was to examine the differentiated item functioning and item bias of mathematics items in the Programme for International Student Achievement 2012…

Due to their test economy and objective evaluability, multiple-choice items are used much more frequently to test knowledge than constructed-response questions. However, studies point out that dependencies may exist between the individual test result and the test format (multiple-choice or constructed-response). Studies testing economic knowledge…

The main purpose of this study is to develop a perceived stress scale based on Classical Test Theory (CTT) and Graded Response Model (GRM); to compare the parameters of the items in the scale that are tried to be developed according to both models, and to determine under which theory the measurement tool produces more reliable and valid results…

When we administer educational achievement tests, we want to be confident that the resulting scores validly indicate what the test takers know and can do. However, if the test is perceived as low stakes by the test taker, disengaged test taking sometimes occurs, which poses a serious threat to score validity. When computer-based tests are used,…

Theories of reading and writing development suggest that the factor structure of achievement batteries could change across development. As a result, it is important to test achievement batteries for invariance across development. The purpose of these analyses is to determine whether the factor structure of reading, writing, and oral language…

This note highlights and illustrates the links between item response theory and classical test theory in the context of polytomous items. An item response modeling procedure is discussed that can be used for point and interval estimation of the individual true score on any item in a measuring instrument or item set following the popular and widely…

Validity is broadly defined as how well something measures what it's supposed to measure. The reliability and validity of scores from assessments are two concepts that are closely knit together and feed into each other.

The purpose of this study is to adapt the Professional Learning Activities Scale (PLAS) developed by Geijsel, Sleegers, Stoel, and Krüger (2009) into Turkish through conducting the relevant validity and reliability analyses. This study followed the pathway recommended by Hambleton and Patsula (1999) for the adaptation process. The data we used…

Identity has been proposed as a mechanism to increase persistence within Science, Technology, Engineering and Mathematics (STEM) education programs. To assess the impact of identity on STEM persistence, measures that produce valid and reliable data within a given STEM discipline need to be employed. Therefore, this study developed and evaluated…

In large-scale low-stake assessment such as the Programme for International Student Assessment (PISA), students may skip items (missingness) which are within their ability to complete. The detection and taking care of these noneffortful responses, as a measure of test-taking motivation, is an important issue in modern psychometric models.…
