Each year, in middle and high school classrooms, secondary science teachers introduce their students to the periodic table of elements (herein the periodic table). According to the Next Generation Science Standards (NGSS Lead States, 2013), one of the performance expectations states that high school students should be able to, "Use the…

The integration of web-based discussion platforms in education is increasingly recognized for its potential to enhance pedagogical practices. This study examined the impact of web-based discussion tools on teachers' pedagogical practices in teaching organic chemistry in selected Rwandan secondary schools. The study adopted sequential explanatory…

The purpose of this study was to analyze the effectiveness of scripted biology curriculum as a means of providing students with the information required to increase content knowledge, while comparing curriculum developed by the teacher that utilizesthe Understanding by Design (UbD) framework (Wiggins & McTighe, 2005). The study used a mixed…

There is a wide variety of ways for instructors to seek to improve diversity, equity, inclusion, and respect (DEIR) in chemistry through their instruction. One way is to talk with students explicitly about equity and injustice in science. We propose a curricular framework for teaching about equity as a way to improve DEIR in science classes at the…

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…

Although teachers' instruction has been extensively studied, there is a dearth of research investigating how teachers design lessons and integrate new information into their existing lessons. This study utilized a case study approach to examine how teachers engaged in a nanoscale science professional development experience integrated new science…

The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

Students at upper secondary and college level in many countries are introduced to quantum physics (QP) in a mostly mathless course. Research shows that addressing epistemological and philosophical aspects would be beneficial for novice students' conceptual understanding. However, physics teachers seldom address these nature of science (NOS)…

The study was about a novel approach to Integrated Science teaching and learning in a selected Ghanaian junior high school. In this study, the approach to teaching and learning Integrated Science has been made entirely new and meaningful in the sense that the four learning behaviours (acquisition of knowledge, comprehension, application of…

"Instructional Sequence Matters, Grades 9-12" is the one-stop resource that will inspire you to reimagine your approach to high school physical science. The book discusses the 5E (Engage, Explore, Explain, Elaborate, and Evaluate) as a specific pathway for teaching and learning. It also shows how simple shifts in the way you arrange and…

In this study we investigated how a theoretical framework we developed for making differentiated instruction practical worked out in a trajectory (1 year, 5 sessions) that aimed to support 5 secondary biology teachers in designing differentiated instruction practices. The key feature of the framework is the development of cost-effective…

As science classrooms become more linguistically diverse, it is becoming increasingly important that pre-service teachers (PSTs) are trained with the skills and knowledge they need to support science learning for all students, especially English Learners. The purpose of this study was to determine how 11 secondary science PSTs' instructional…

In this study, we examined the teaching emphasis of the history of science (HOS) in science lesson plans. The examination was based on a five-dimensional framework, which comprises conceptual, procedural, epistemological, affectional, and social dimensions. Content analysis was employed as the research methodology, targeting 71 copies of science…

The debate on the use of pesticides is very current in the public media when it comes to topics such as organic farming, bee mortality, and the use of glyphosate. The broad range of pesticide applications and their potential environmental impact makes pesticides an interesting topic for science education in general and for chemistry teaching in…

Constructing scientific explanations of natural phenomena is an important aim of science education. Explanation oriented science teaching approaches encourage learners to engage in sense-making discussions and construct the causal accounts of the phenomena under study. This article demonstrates a lesson-design model that guides biology teachers on…
