Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Scientific Practices play a central role in the Next Generation Science Standards, influencing the standards of more than 70% of students in the United States. Therefore, a view of what has been studied about Scientific Practices in Science Education, globally in the past decade is relevant. Thus, 44 articles from international journals in Science…

Competence-based, science e-testing (CBSeT) is a novel external assessment tool which provides feedback to science teachers about their students' competence-based skills, thereby giving relevant assessment information which teachers could potentially use in their teaching practice. The aim of this study was to determine the extent to which…

This study aims to investigate the effectiveness of a research-based learning management plan microbiology and its impact on vocational education certificate students in the Animal Science department at Mahasarakham College of Agriculture and Technology. The research instruments included five research-based learning plans of microorganisms and…

There is a contradiction in the literature about the effect of REACT strategy on science achievement. This study aims to resolve this contradiction by determining the effect of REACT strategy on student science achievement and the factors affecting this strategy by integrating findings obtained from both qualitative and quantitative studies. The…

Learning outcomes are an essential element in curriculum development because they describe what students should be able to do by the end of a course or program and they provide a roadmap for designing assessments. This article describes the development of competency-based learning outcomes for a one-semester undergraduate introductory human…

Integrating decision-making learning goals within science classrooms has been increasingly common for science educators and researchers to help develop students' science literacy skills. These learning goals include understanding and applying scientific information as well as recognizing tradeoffs amongst multiple perspectives when decision-making…

Assessment instruments that generate quantitative data on attributes (cognitive, affective, behavioral, "etc.") of participants are commonly used in the chemistry education community to draw conclusions in research studies or inform practice. Recently, articles and editorials have stressed the importance of providing evidence for the…

Every school should be able to equip students to have the ability to integrate the knowledge gained with real life in responding to global challenges. Assessment of learning outcomes in the form of cognitive and skill aspects must go hand in hand. This study aims to produce: (1) a critical thinking model integrated with the science process, (2)…

To help teachers implement new, research-based approaches for leveraging technology to improve science, technology, engineering and mathematics (STEM) learning, a systematic review of the research literature on the impact of integrating innovative digital technology in STEM and computer science curricula and classrooms was conducted. For purposes…

Practical skills in chemistry are considered an essential outcome of an undergraduate chemistry degree. To achieve this, chemistry curricula are designated a substantial number of hours in teaching laboratories. However, the general method of a summative assessment of these sessions is through a written laboratory report and not through the actual…

This paper describes an innovative method to evaluate students' learning after teaching the topic of stereochemistry using molecular models in an organic chemistry course for second-year pharmacy students at Princess Nourah bint Abdulrahman University. This method is practical and relevant and directly measures the intended learning skills. It is…

This study sought to assess the level of secondary students' scientific literacy in suburban schools in Malaysia and England, a research area which to date has not been fully explored in the literature. The study analyzed the data using the OECD's three domain-specific competencies of scientific literacy, namely: (i) explain phenomena…

Science learning in the 21st century should develop the abilities of the students to find solutions to the problems. This task requires a set of skills called Higher Order Thinking Skills (HOTS) and innovative assessment should be designed to gauge the acquisition of these skills. Thus, this study aimed to create an innovative HOTS-based…

The Qualifications Regulator in England (Ofqual) has decided that with the implementation of revised (linear) science specifications, first teaching from September 2015, the assessment of practical skills will not contribute to the overall qualification grade. This could have significant implications for post-16 science teaching. The decision was…
