The purpose of this study was to determine the science education curriculum in vocational high schools. We used the literature review method to obtain data. We analyzed the national curriculum in Indonesia regarding science education in vocational schools. The results showed that almost all vocational programs in vocational schools contain…

Curriculum materials can play a major role in shaping teachers' thinking about instruction and content as well as serve as a support for teachers' learning. With the inclusion of engineering in NGSS, many teachers may be turning to existing curriculum materials to help them infuse engineering into their science classroom, especially when they do…

The National Survey of Science and Mathematics Education (NSSME) has provided periodic snapshots of K-12 science instruction in the United States for over 40 years. Study topics include teacher background and beliefs, professional learning opportunities, course offerings, instructional objectives and activities, resources for instruction, and…

Embryology is an essential component to understanding human anatomy. It requires an in-depth understanding of 3D knowledge but is primarily taught with 2-dimensional resources. In particular, the development of the human heart is a complex process and difficult to understand using traditional teaching methods. We present here a series of heart…

This research was motivated by several obstacles, including teachers in the learning process only focusing on thick textbooks and the student worksheets provided by the school were less interesting and effective. The aim of this research is to develop chart learning media based on Science Technology Engineering Mathematics (STEM) to improve…

Background: Although cutting-edge chemistry research can be an interesting and motivating context for students in pre-university education, few characteristics of supportive and effective learning materials based on such contexts are available. Purpose: In this study we investigated the design, implementation, and evaluation of context-based…

Throughout the long history of astronomy, scientists have repeatedly written fictional stories, which often lend themselves to use in the classroom thanks to the authors' in-depth knowledge and an appealing storyline. This article uses the novel 'The Black Cloud', written by the well-known astronomer Fred Hoyle, to show which physical-astronomical…

Recent calls in education have emphasized the critical need for curricula in the sciences to support student development of the general and disciplinary-specific practices that are relevant to modern scientific research and careers, as well as foundational scientific knowledge that reflects recent advances. In this regard, the life sciences,…

This study used nationally representative data from the 2011 National Assessment of Educational Progress (8th-grade Science) and the 2018 National Survey of Science and Mathematics Education toward two primary purposes: (1) to examine the association between teachers' formal (university) content preparation in science and student outcomes in…

This paper seeks to investigate how students' performance in Chemistry can be enhanced by using kitchen resources in Calabar. The kitchen resources used included a piece of white paper, a swab, lemon juice and candle. These were used to show that paper cellulose was oxidized by flame due to the catalysis of lemon juice acid. Other materials used…

This study describes how 19 middle-school science teachers responded to an engineering design task in the context of water quality and environmental science professional development (PD). The study relies on teacher created prototypes, presentations, graphic organizers, and qualitative memos to illustrate the challenges and successes of the PD. In…

We examine how a unique professional learning experience for teachers, which consists of an opportunity to (a) co-design a new instructional model intended to give students opportunities to participate in scientific argumentation, (b) develop instructional materials based on the new model, and then (c) use the materials inside their classrooms, is…

This report describes an activity that helps organic chemistry students to better understand organic molecules as 3-dimensional objects. To accomplish this goal, the activity employs a unique three-way combination of analyzing computer-generated 3-dimensional renditions of open access X-ray crystallography data, building physical 3-dimensional…

The present study aims to discuss the influence of the flipped learning method (FLM)--on high school biology learners to improve the results of their biology attainment tests along with their use of social interactions while learning. By applying quasi-experimental study, 37 female high school biology learners in 2 intact grade 10 classes in…

This qualitative designed study explored teacher perceptions about science instruction. Three research questions were developed to guide the study. To facilitate the collection of data, the three research questions that guided this study were further broken down into ten interview questions. Purposeful sampling technique was used to select…
