This randomised controlled trial used a mixed-methods approach to investigate the frequency and how elementary teachers integrated engineering design (ED) principles into their science instruction following professional development (PD). The ED components of the PD were aligned with Cunningham and Carlsen's [(2014). "Teaching engineering…

Based on 10 preservice science teachers in 4 schools, this study presents a detailed analysis of how preservice teacher expectation interacts with school practicum and authentic classroom action of inquiry-based instruction. Classroom observation, lesson plan analysis, and interviews revealed that inquiry-based instruction in the expectation and…

This paper aims to explore how the use of lesson study approach with a constructivist framework could enhance Year 9 students' conceptions of pressure specifically on the topic of manometer reading in determining gas pressure. A diagnostic test was first administered to three Year 10 classes to help teachers identify student difficulties in…

This research aims at revealing (1) the suitability of physics e-scaffolding teaching media with mathematical and image/diagrammatic representation, as well as (2) the effectiveness of the e-scaffolding teaching media with mathematical and image/diagrammatic representation to improve students' problem solving ability and scientific attitude. It is…

Earth's topographic surface forms an interface across which the geodynamic and geomorphic engines interact. This interaction is best observed along crustal margins where topography is created by active faulting and sculpted by geomorphic processes. Crustal deformation manifests as earthquakes at centennial to millennial timescales. Given that…

The study aims to investigate the effect of using constructivist learning model in teaching science, especially in the subject of light: its nature, mirrors, lens, and properties, on the achievement of eighth-grade students and their scientific thinking. The study sample consisted of (136) male and female 8th graders were chosen from two basic…

Through the GK-12 program of the National Science Foundation, graduate student fellows in a coastal marine and wetland studies program were trained to present targeted science concepts to middle- and high-school classes through their own research-based lessons. Initially, they were taught to follow the 5-E learning cycle in lesson plan…

This is the start of a road map for the effective introduction of inquiry-based learning in chemistry. Advantages of inquiry-based approaches to the development of scientific literacy are widely discussed in the literature. However, unless chemistry educators take account of teachers' reservations and identified disadvantages such approaches will…

Physics is all around us. It is present in the minute world of the atom and in the vast universe. There is physics in our everyday life. From the moment we arise to the time we go to sleep, our activities involve physics. When we cook our food, iron our clothes, wash the dishes, listen to the radio, or answer a telephone call, we make use of the…

Research Findings: This study compared the effects of content-based shared book-reading instruction versus an explicit vocabulary-only condition on the vocabulary development of preschool dual language learners (DLLs). Using shared book reading as the mode of instruction, we randomly assigned 48 bilingual preschool teachers and 281…

The aim of this study is to investigate the effects of training teachers to enhance their students' achievements in water resource and disaster course and to compare the effects of using the curriculum framework between training teachers or using curriculum framework in the secondary schools in Khon Kaen Province of Thailand. It was found that the…

While research has shown that elementary (K-5) students are capable of engaging in the scientific practice of explanation construction, commonly-used elementary science curriculum materials may not always afford them opportunities to do so. As a result, elementary teachers must often adapt their science curriculum materials to better support…

The Earth sciences are newly marginalized in K-12 classrooms. With few high schools offering Earth science courses, students' exposure to the Earth sciences relies on the teacher's ability to incorporate Earth science material into a biology, chemistry, or physics course. ''G.E.T. (Geoscience Experiences for Teachers) in the Field'' is an…

To support the implementation of the Common Core State Standards (CCSS), the Bill and Melinda Gates Foundation invested in the development and dissemination of two tools aimed at operationalizing classroom instruction based on the standards: (1) the Literacy Design Collaborative (LDC)'s Framework; and (2) the Math Design Collaborative (MDC)'s…

The Bill and Melinda Gates Foundation has invested in the development and dissemination of high-quality instructional and formative assessment tools to support teachers' incorporation of the Common Core State Standards (CCSS) into their classroom instruction. Lessons from the first generation of standards-based reforms suggest that intense…
