Research about modeling emphasizes the importance of heterogeneity in science learning. At the same time, a growing body of scholarship seeks curricular pathways for epistemic and representational convergence. In response to this tension, we propose two constructs: heterogeneity-seeking curricula and commitments. Heterogeneity-seeking curricula…

The Malaysian Education Blueprint 2013-2025 has increased emphasis on learning using projects and group work to support 21st century education goals in Malaysian secondary schools. In response to that, the current lower secondary science textbooks following the Integrated Curriculum for Secondary School (KSSM) have been revamped to include a…

The aim of this study was to examine the knowledge levels of secondary school students about global warming in terms of various variables. A total of 1008 students studying in secondary schools in Mus Province city center were included in the study. This study was conducted through a survey design and the Scale of Knowledge about Global Warming…

"Citizen science" popularly refers to a participatory approach in which lay persons voluntarily contribute data toward scientific enterprise. Although citizen science may provide unique opportunities for pre-college students to engage in data-intensive science practices, little is known about whether or how citizen science interacts with…

This century, the twenty-first century, is a century of science and technology explosion. This is the period when the boon of science has arrived in almost every corner of the world. One such example is exposure to information (data) using a cell phone, bypassing a computer. This has made information available to the masses at a much cheaper rate…

The visibility of female role models in science is vital for engaging and retaining women in scientific fields. In this study, we analyse four senior secondary science courses delivered across the states and territories in Australia: Biology, Chemistry, Environmental Science, and Physics. We compared male and female representation within the…

The purpose of the study is to see if there is a significant difference in chemistry exam achievement growth for 10th grade students in classes with problem-based learning compared with those students in classes with direct instruction. The state in which the study was conducted is developing new standards that are challenging students more than…

The purpose of this study is to test the relationship between seventh-grade students' personal epistemology for science, subjective task value, and science self-efficacy, with prior achievement serving as a moderator. The mediating role of subjective task value is proposed in the prediction of the relationship between personal epistemology for…

Students in urban, low-income communities can lack access to environmental science outreach in natural settings. As a result, they may face barriers to applying course content to real-world contexts and developing an agentic, hopeful stance towards environmental stewardship. In this paper, we describe a partnership between a maritime museum and…

High school biology students are provided few classroom opportunities to learn natural history or to see themselves as scientists. This poses a risk to their gaining the basic knowledge needed to play a positive role in the biodiversity crisis. However, science-as-practice in the classroom introduces the opportunity to equip students with…

In the sciences, energy is an important idea to get insight into phenomena, as energy can help to reveal hidden systems and processes. However, students commonly struggle to use energy ideas to interpret and explain phenomena. To support students in using energy ideas to interpret and explain phenomena, a range of different graphical…

Student teachers struggle to identify themselves as teachers in their field placement during their student teaching year, and some of the difficulty can be attributed to the change they encounter when they must communicate scientific ideas to students in a language that differs from how they recently learned science at the university level. Using…

In recent years, general relativity (GR) and gravitational-wave astronomy have emerged both as active fields of research and as popular topics in physics classrooms. Teachers can choose from an increasing number of modern instructional models to introduce students to relativistic ideas. However, the true potential of an instructional model can…

Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

The aim of this research is to examine the effects of laboratory activities based on the predict-observe-explain (POE) strategy on the understanding of photosynthesis and respiration concepts of pre-service science teachers, and their attitudes towards biology science and course and biology laboratory. Pre- and post-test designs with an…
