Students' science identity has been identified as an important construct that positively influences their learning engagement, persistence, and career intentions in science. This paper reported the process of developing and validating an instrument that can be used to assess high school students' science identity. The development of this…

Logical reasoning as part of critical thinking is becoming more and more important to prepare students for their future life in society, work, and study. This article presents the results of a quasi-experimental study with a pre-test-post-test control group design focusing on the effective use of formalisations to support logical reasoning. The…

Learners underperform in stoichiometry as they lack conceptual reasoning of the underlying concepts and the ability to solve stoichiometric problems. Therefore, it was necessary to determine if there is a statistical correlation between problem-solving skills and conceptual reasoning in stoichiometry and if so, whether one can significantly…

The internet is prevalent in society today, and user-friendly web-based productivity tools are readily available for developing diagnostic instruments. This study sought to determine the affordances of a web-based diagnostic instrument on ionisation energy (wIEDI) based on the pen-and-paper version, the Ionisation Energy Diagnostic Instrument…

Recycling and its applications are growing significantly due to the great potential for solving a range of environmental problems in society. Nevertheless, there are currently very few instruments that can provide valid and reliable data on students' attitudes toward recycling. In this regard, this article focuses on the development and validation…

Background: Misconceptions are major obstacles to learning physics, and the concepts of heat and temperature are some of the common misconceptions that are encountered in daily life. Therefore, it is important to develop valid and reliable tools to determine students' misconceptions about basic thermodynamics concepts. Three-tier tests are…

This fifty-item test is intended for the 'Responsibility' unit of the 'Law in a Free Society' materials published by the California Bar Association. The test was administered as a pre- and post-test to more than 600 grade 11 students. The pre-test data for all students were item-analyzed and the results are made available along with a table of…
