The aim of this research is to examine the effect of subject matter knowledge education (SMKE) on the pre-service science teachers' approach to error about plane mirrors. This study was conducted using developmental research and phenomenology designs, which are qualitative research methods. In the study, the data were analyzed with the descriptive…

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…

One of the universal responses to tackling global climate change is teaching climate change concepts at all levels of formal education. This response requires, among other things, teachers who are fully literate about climate change science, so that they can explain the concepts underlying the causes, impacts and solutions of climate change as…

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures…

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…

The Climate Stewardship Survey (CSS) was developed to measure knowledge and perceptions of global climate change, while also considering information sources that respondents 'trust.' The CSS was drafted using a three-stage approach: development of salient scales, writing individual items, and field testing and analyses. Construct validity and…

Concept inventories (CIs)--typically multiple-choice instruments that focus on a single or small subset of closely related topics--have been used in science education for more than a decade. This paper describes the development and validation of a new CI for astronomy, the "Star Properties Concept Inventory" (SPCI). Questions cover the areas of…

The present study investigates stereotypical beliefs about cyber bullying in terms of myths, a well applied concept in the study of beliefs concerning sexual aggression. The level of acceptance of cyber bullying myths (low vs. high) and the relation of myth acceptance to a number of demographic variables such as gender, field of studies, frequency…

In order to address HIV infection among college students, a comprehensive measure is needed that can be used with samples from culturally diverse populations. Therefore, this paper assessed the reliability and validity of an HIV/AIDS questionnaire that measures fours dimensions of HIV/AIDS awareness--factual knowledge, prejudice, personal risk,…
