Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

The development of scientific visual literacy has been identified as critical to the training of tomorrow's scientists and citizens alike. Within the context of the molecular life sciences in particular, visual representations frequently incorporate various components, such as discipline-specific graphical and diagrammatic features, varied levels…

We used the Rule Space Model, a cognitive diagnostic model, to measure the learning progression for thermochemistry for senior high school students. We extracted five attributes and proposed their hierarchical relationships to model the construct of thermochemistry at four levels using a hypothesized learning progression. For this study, we…

In this article, we present several modifications to the Test of Understanding Graphs in Kinematics. The most significant changes are (i) the addition and removal of items to achieve parallelism in the objectives (dimensions) of the test, thus allowing comparisons of students' performance that were not possible with the original version, and (ii)…

K-12 intervention studies often include fidelity of implementation (FOI) as a mediating variable, though most do not report the validity of fidelity measures. This article discusses the critical need for validated FOI scales. To illustrate our point, we describe the development and validation of the Implementation Validity Checklist (IVC-R), an…

The task of turning undergrads into academics requires teaching them to reason about the world in a more complex way. We present the Argument Complexity Scale, a tool for analysing the complexity of argumentation, based on the Integrative Complexity and Conceptual Complexity Scales from, respectively, political psychology and personality theory.…

The current paper reports an experience implementing a small-scale narrow listening scheme (one of the varieties of extensive listening) with intermediate learners of English as a foreign language in a Colombian university. The paper presents (a) how the scheme was designed and implemented, including materials and procedures (the process); (b) how…

Even though experimental design (ED) in open inquiry is important for more authentic scientific inquiry, it is not easy for students. The objective of this research was to identify factors considered important in students' ED and explore how to utilize it to improve students' ED. To achieve the objective, in the first step, eighteen middle-school…

The aim of the research was to identify how Slovenian primary and secondary school students of various age groups explain the particulate nature of the states of matter of water and air. The qualitative research included five 12, 14, and 16 year old students. A semi-structured interview including four computer-displayed tasks was used for the data…

Purpose: A growing body of research has focused on the topic of inclusive education for ethnic minorities in Hong Kong. At the same time, few scholars have explored the role technology can play in enhancing inclusivity within the context of quality education. This study examines how the differentiated use of technology that takes into account…

Compulsory second foreign language phenomenon has emerged in Turkey in the near term. German was made compulsory as the second foreign language in Anatolian high schools in the academic year 2012-2013. As with the first foreign language teaching, there are also problems with the second foreign language teaching. The revealing of the problems in…

Teachers and school leaders frequently make decisions about which strategies will best support students who struggle academically or behaviorally, but evidence-based information about the quality of these strategies is not always available. Resources as the What Works Clearinghouse and the Regional Education Laboratories can help educators…

It is a common finding across languages that young children have problems in understanding patient-initial sentences. We used Tagalog, a verb-initial language with a reliable voice-marking system and highly frequent patient voice constructions, to test the predictions of several accounts that have been proposed to explain this difficulty: the…

Students' perceptions are one of the sources that can be used to capture teachers' PCK. Therefore, the aim of this study was to develop a scale to determine secondary students' perceptions of their teachers' PCK. Validity and reliability studies were conducted with 659 students. Both exploratory factor analysis and confirmatory factor analysis…

An Oral Proficiency Interview (OPI) may be evaluated either during the interview procedure (direct-method) or from a tape-made oral interaction (semi-direct method). Such variety in methods of assessment can influence test takers' scores extensively. However, it is not conclusive whether such differences are due to test format or something else.…
