Against the backdrop of internationalisation of education and the emergence of English as a global language, medium of instruction (MOI) has long been a controversial issue globally. The present study examined the relationships between secondary-level MOI (English, EMI; Chinese, CMI) and learners' tertiary-level academic achievement and…

Smoothing techniques are designed to improve the accuracy of equating functions. The main purpose of this study is to compare seven model selection strategies for choosing the smoothing parameter (C) for polynomial loglinear presmoothing and one procedure for model selection in cubic spline postsmoothing for mixed-format pseudo tests under the…

Context-based questions can be effective in reducing test anxiety and increasing science achievement. The purpose of this research was to determine the effects of context-based questions on the test anxiety and science achievement of secondary school students enrolled in a science course, in relation to gender. Seventy students who were found to…

The objective of this study was to examine the relationship of formative tests to early learning ability of students in the science learning style. This research used an experimental method with a 2 x 2 factorial design. The participants comprised all the students in class VII of the Islamic Junior High School State of Kolaka, a total of 343…

Teachers' professional knowledge is assumed to be a key variable for effective teaching. As teacher education has the goal to enhance professional knowledge of current and future teachers, this knowledge should be described and assessed. Nevertheless, only a limited number of studies quantitatively measures physics teachers' professional…

Growing recognition of the central importance of fostering an in-depth understanding of natural selection has, surprisingly, failed to stimulate work on the development and rigorous evaluation of instruments that measure knowledge of it. We used three different methodological tools, the Conceptual Inventory of Natural Selection (CINS), a modified…

In this article, Structural communication grid (SCG), an alternative measurement and evaluation technique, has been firstly summarised and the design, development and implementation of a computer based SCG system have been introduced. The system is then tested on a sample of 154 participants consisting of candidate students, science teachers and…

A comparison is presented of alternate-choice and true-false item forms used in an undergraduate natural science course. The alternate-choice item is a modified two-choice multiple-choice item in which the two responses are included within the question stem. This study (1) compared the difficulty level, discrimination level, reliability, and…

A study with 503 applicants to the University of Helsinki (Finland) medical school compared the predictive validity of multiple-choice science tests and a "learning-from-text" test (LFT) designed to measure deep-level text processing. Results indicated the LFT was the best predictor of student academic progress in basic science courses.…
