This paper presents a mixture item response tree (IRTree) model for extreme response style. Unlike traditional applications of single IRTree models, a mixture approach provides a way of representing the mixture of respondents following different underlying response processes (between individuals), as well as the uncertainty present at the…

Control of variables strategy (CVS) is a core scientific reasoning skill related to domain-general experimentation for evaluating an experimental system and deducing valid conclusions. This study aims to develop, validate, and explore latent factors predicting item difficulty in the test, measuring CVS in physics for high school students. The…

Background: The idea of using low-stakes assessment results is often mentioned when designing educational system reforms. However, when tests have no consequences for the students, test takers may not make enough effort when completing the test, and their lack of engagement may negatively affect the validity of the conclusions of the studies that…

This research proposes a new statistic for testing latent variable distribution fit for unidimensional item response theory (IRT) models. If the typical assumption of normality is violated, then item parameter estimates will be biased, and dependent quantities such as IRT score estimates will be adversely affected. The proposed statistic compares…

This study aimed to explore students' perceptions of school practices that have ethical significance using an integrative model based on the eighth-grade Trends in International Mathematics and Science Study (TIMSS) 2015. The sample comprised 280,130 students, 8,353 principals, and 8,353 teachers from 8,353 different schools across 45 countries.…

The purpose of this study is to examine the self-efficacy perception levels of science teachers for assessment literacy in terms of various variables by determining them and to reveal the correlation between them. The research was designed in the scanning model, one of the non-experimental quantitative methods. The sample of the study consists of…

The present study aims to discuss the influence of the flipped learning method (FLM)--on high school biology learners to improve the results of their biology attainment tests along with their use of social interactions while learning. By applying quasi-experimental study, 37 female high school biology learners in 2 intact grade 10 classes in…

This study aims to develop a score equating application for computer-based school exams using parallel test kits with 25% anchor items. The items are arranged according to HOTS (High Order Thinking Skill) category, and use a scientific approach according to the physics lessons characteristics. Therefore, the questions were made using stimulus,…

The purpose of this study is to compare the effects of inquiry-based learning and the regular science curriculum on students' learner autonomy and conceptions of learning. The students in the experimental group engaged in inquiry beginning with structured, continuing with guided and ending with open, while the students in the comparison group…

This study aims to evaluate the psychometric properties of the developed diagnostic assessment test and to identify student misconceptions in science in terms of school grades. 153 students were gathered by using random sample from 10th to 12th grade in senior high schools. The 32 items of the two-tier multiple-choice diagnostic test were…

Ishimoto, Davenport, and Wittmann have previously reported analyses of data from student responses to the Force and Motion Conceptual Evaluation (FMCE), in which they used item response curves (IRCs) to make claims about American and Japanese students' relative likelihood to choose certain incorrect responses to some questions. We have used an…

In laboratory study environments, dialogue-videos, or videos of a tutor and a tutee solving problems together, have been shown to more effectively improve student learning than monologue-videos, or videos of tutors solving problems alone. Yet, few studies have replicated these findings in the context of authentic university classrooms. Here, we…

Studies examining gender differences in introductory physics show a consensus when it comes to a gender gap on conceptual assessments; however, the story is not as clear when it comes to differences in gendered performance on exams. This study examined whether gendered differences exist on midterm and final exams in introductory physics courses…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

Environmental science is a broad, interdisciplinary field integrating aspects of biology, chemistry, earth science, geology, and social sciences. Mastery of basic science concepts and reasoning are therefore necessary for students to understand the interactions of different components in an environmental system. How do teachers identify and assess…
