In exploratory factor analysis, although the researchers decide which items belong to which factors by considering statistical results, the decisions taken sometimes can be subjective in case of having items with similar factor loadings and complex factor structures. The aim of this study was to examine the validity of classifying items into…

This study presents a bibliometric analysis of research on mathematics education from 1980 through 2020. The purpose of the study is to provide scientific data on the distribution pattern of mathematics education journals, the most prolific authors, countries, institutions, current research topics, potential international collaboration, and…

The purpose of this study was to develop and validate a survey of opportunities to participate (OtP) in science that will allow educators and researchers to closely approximate the types of learning opportunities students have in science classrooms. Additionally, we examined whether and how opportunity gaps in science learning may exist across…

Background: Several inventories have been developed to assess social problem-solving. However, these instruments originally developed for adult or adolescence and do not capture the full range of main interpersonal relationships over which elementary students resolve daily life interpersonal problems and apply elementary-age typical responses.…

This paper illustrates the role of metalanguage in an explicit literacy instruction to talk about the forms and functions of scientific genres, particularly the genre of explanation. In the context of science, metalanguage refers to the technical terms for talking "about" scientific language using words like law, hypothesis, and…

Validation of data collection instruments is a necessary step in all research and should be regarded as an integral component in every stage of the research process; however, the validation process is often not accounted for in detail in published studies. The purpose of this paper is to describe the development and validation of the Ungspråk…

Current conceptualisations of feedback contend that it should be a learner-centred process. In practice, however, text-based feedback comments from teachers are a convenient and common source of feedback information, despite appearing to be contra-indicative of learner-centred models. This raises the question of how teachers can tackle the design…

The purpose of this study was to adapt the Statistics Anxiety Rating Scale (STARS) for a Greek student population. The STARS was administered to 890 Tertiary Education students in two Greek universities.

[2017]. "Feedback-informed treatment in clinical practice. Reaching for excellence." American Psychological Association (APA).…

Multilevel modeling (MLM) is a statistical technique for analyzing clustered data. Despite its long history, the technique and accompanying computer programs are rapidly evolving. Given the complexity of multilevel models, it is crucial for researchers to provide complete and transparent descriptions of the data, statistical analyses, and results.…

Course design is critical to online student engagement and retention. This study focused on the development and validation of an online course design elements (OCDE) instrument with 38 Likert-type scale items in five subscales: (a) overview, (b) content presentation, (c) interaction and communication, (d) assessment and evaluation, and (e) learner…

Adoption of evidence based instructional practices is not widespread in American institutions of higher education. This is due in part to reforms focusing on individual teaching practices rather than conditions for system reform. Since measurement of organizational conditions is critical for widespread change, we developed and validated the Survey…

The aim of this study is to examine the opinions of preservice physical education teachers towards the teaching field knowledge test (TFKT). The test, which constitutes half of the score required to be appointed as a teacher is believed to determine the level of knowledge of preservice teachers in their fields of teaching. Preservice teachers'…
