The Framework for K-12 science education (The "Framework") and Next Generation Science Standards (NGSS) emphasize the usefulness of learning progressions in helping align curriculum, instruction, and assessment to organize the learning process. The "Framework" defines three dimensions of science as the basis of theoretical…

Here, we propose the use of magnetic levitation (MagLev) device, as a simple, cheap, and portable experimental technique to measure the density of diamagnetic materials in laboratory settings. We highlight the basics of a standard MagLev system for measuring the density of unknown diamagnetic materials/objects using permanent magnets, paramagnetic…

Background: In many classrooms, science textbooks remain a significant tool, functioning in some instances as the de facto curriculum and influencing pedagogical practices. Such conventions are more noticeable in the science classrooms of developing countries, like Jamaica, because of a chronic shortage of specialist science teachers and the…

Recent conceptualizations of science literacy, a key aim of contemporary science education, suggest defining it as a function of actual uses of science in daily life. We characterize expressions of science literacy in online authentic public discourse, using content analysis of a year's worth of widely-read Israeli online news site coverage of…

Background: The growing population of students that are learning science through a Content and Language Integrated Learning approach (CLIL) has led to concerns about these students' ability to fully participate in a rich classroom discourse to develop content knowledge. A lack of information about science development through classroom discourse in…

Individuals have different opinions and views on many socio-scientific issues such as stem cells, influenza vaccine, cloning, nuclear power plants, and organ transplantation that affect social life. Scientific attitudes and scientific literacy of individuals can affect their approach to socio-scientific issues. This research aims to reveal how…

Stoichiometry calculation competence tends to be particularly poor in the developing world, even among teachers. Various methods, including the unit factor method, have the potential to be effective in developing such competence. To evaluate the likelihood of such a generic proportion method, which downplays traditional formula usage, succeeding…

This study aims to determine the knowledge levels in the Nature and History of Science course of the prospective teachers studying in the science education program and their views following the course. Six interview questions were asked to the pre-service teachers in the science education program about the Nature and History of Science course.…

Planetariums have been used for a long time in astronomy education. Due to some disadvantages of permanent planetariums, it is seen that portable planetariums have become popular in recent years. Portable planetariums, due to their easy set up in anywhere, offer opportunities for those students studying in the regions where there are not…

A design study was conducted to test a machine learning (ML)-enabled automated feedback system developed to support students' revision of scientific arguments using data from published sources and simulations. This paper focuses on three simulation-based scientific argumentation tasks called Trap, Aquifer, and Supply. These tasks were part of an…

Plants are crucial parts of ecosystems but are traditionally considered boring and difficult by students. It is therefore not clear whether factual knowledge about plants contributes to building positive attitudes and interest in botany. We investigated whether factual knowledge about monocotyledonous plants is associated with secondary students'…

Sensor systems have the potential to make abstract science phenomena concrete for K-12 students. Internet of Things (IoT) sensor systems provide a variety of benefits for modern classrooms, creating the opportunity for global data production, orienting learners to the opportunities and drawbacks of distributed sensor and control systems, and…

The (written) state curriculum is one of the cornerstones influencing education. Its specifically mediated by textbooks. In an open textbook market, the influence of the state curriculum is limited, and the main responsibility passes to individual schools or teachers. In order to understand education from the potential attainment of curriculum…

This study aims to develop valid and reliable Islamic Education (PAI) teaching materials based on integrative Islamic science in Class X of Islamic High School in Indonesia. This research uses Borg & Gall's research and development model. The results showed that the content and construct validity of the teaching materials for Islamic Education…

The National Science Teaching Association (NSTA) and the "Next Generation Science Standards" ("NGSS") have attempted to make planning easier for teachers by creating a common resource bank, but there is no unit design process specifically created for science teachers in a project- and inquiry-based classroom. Without a common…
