In the present study, we examined the effects of feedback that corrects and contrasts a student's own erroneous solutions with the canonical, correct one (CEC&C feedback) on learning in a conceptual change task. Sixty undergraduate students received expository instruction about natural selection, which presented the canonical, scientifically…

The Programme for International Student Assessment (PISA) is an important international study of 15-olds' knowledge and skills. New results are released every 3 years, and have a substantial impact upon education policy. Yet, despite its influence, the methodology underpinning PISA has received significant criticism. Much of this criticism has…

A computer program was developed to estimate speed-accuracy response models for dichotomous items. This report describes how the models are estimated and how to specify data and input files. An example using data from a listening section of an international language test is described to illustrate the modeling approach and features of the computer…

Purpose: This study examined whether children and adults with developmental language disorder (DLD) could use distributional information in an artificial language to learn about grammatical category membership similarly to their typically developing (TD) peers and whether developmental differences existed within and between DLD and TD groups.…

Constituting a metacognitive strategy, system competence or systems thinking can only assume its assigned key function as a basic concept for the school subject of geography in Germany after a theoretical and empirical foundation has been established. A measurement instrument is required which is suitable both for supporting students and for the…

Automating the production of questions for assessment and self-assessment has become recently an active field of study. The use of Semantic Web technologies has certain advantages over other methods for question generation and thus is one of the most important lines of research for this problem. The aim of this paper is to provide an overview of…

The aim of this study was to adapt the scale developed by Hong et al. (2016) to the Turkish culture, to revise the scale as six dimensional by adding the dimensions of hope and frustration and to determine the views of the teachers. The research was carried out with three groups consisting of teachers working in secondary schools in different…

Although the benefits of extensive reading are well known, very little research has investigated the validity of assessment tools to measure general comprehension of graded readers. To address this, quizzes were authored for 42 level 2 Penguin graded readers and administered to 166 students over a semester. Item facility for high-scorers and…

Computational thinking (CT) is regarded as an essential twenty-first century competency and it is already embedded in K-12 curricula across the globe. However, research on assessing CT has lagged, with few assessments being implemented and validated. Moreover, there is a lack of systematic grouping of CT assessments. This scoping review examines…

This paper presents results from a randomized experimental design replicated over four semesters that compared students' performance in understanding landform evolution processes as measured by the pretest to posttest score growth between two treatment methods: an online interactive simulation tool and a paper-based exercise. While both methods…

This paper outlines the key issues of remotely invigilated online exams (RIOEs) and presents ways to avoid and resolve the issues for educators who are considering implementing them. The purpose of this paper is to share the lessons learned during the process of implementing and evaluating RIOEs and highlight the key considerations required to…

The knowledge about affix plays a vital role in the development of word knowledge and vocabulary acquisition. A test for diagnostic information on the level of affix knowledge would be useful in order to inform the test users of what learners have gained or lacked in this integral component of vocabulary knowledge. This paper reports the…

Developing scientific literacy for all students is the most often stated purpose of contemporary science education. Nature of science (NOS) is seen as an important component of scientific literacy. There are various perceptions of NOS in the science education community and NOS itself is an ever-changing construct. This makes it challenging to…

This research evaluates the psychometric properties of short-answer response items under a variety of grading rules in the context of a mobile learning platform in Africa. This work has three main findings. First, we introduce the concept of a differential device function (DDF), a type of differential item function that stems from the device a…

Graphophonemic (GP) knowledge of a language represents the foundation of a good learning start point. In the English as a foreign language (EFL) context, many learners lack adequate GP knowledge of English, resulting in difficulty to master the language skills even at the tertiary level. Thus, this study investigated first-year university,…
