My study was to discover the perceptions of general secondary senior high school biology teachers about the application of curriculum 2013. Their further opinions of biology topics and the instructional practices in the class have supported the findings of this study. In addressing this study, general senior secondary school (GSSS) biology…

Students majoring in science, technology, engineering, and mathematics (STEM) are in high demand. Over 1 million STEM graduates will be needed by 2022 to meet the projected workforce needs (The Progress Report on Coordinating Federal Science, Technology, Engineering, and Mathematics Education, 2016). If students are needed to fulfill jobs in areas…

Given the current emphasis on science, technology, engineering, and math (STEM) education and its key attributes, middle school is an optimal time to implement STEM-based curricula. However, the interdisciplinary and open-ended nature of STEM projects often makes implementation difficult. In this article, we describe a professional development…

The aim of this study was to identify the content of secondary Science curriculum excluded in teaching and learning activities, the reasons behind the omission and its impact on students' learning in the context of Bangladesh. This study used qualitative methodology. Eight teachers were selected and interviewed to investigate what they excluded…

Due to problems related their content and use; textbooks do not achieve the expected effect in learning although they are one of the most important elements of the science curriculum. Questions in textbooks are also important criteria in determining the effect of textbooks. In this study, it was aimed to compare questions in four different science…

The Science, Business and Policy Program (SBP) of the University of Groningen has been a work-based learning program for science master students since two decades. This program, a direct consequence of the Bologna declaration of education in Europe, has a distinctive position in European science curricula. Here, we use a web-based survey…

In this study, we analyzed the perceptions of treatment teachers who participated in a randomized controlled trial study which targeted a science-infused literacy intervention, "Let's Talk Science," for first grade English language learner students. Three aspects, including the effectiveness of the intervention, details of instructional…

Queensland schools are currently teaching with the first National Curriculum for Australia. This new curriculum was one of a number of political responses to address the recurring low scores in literacy, mathematics, and science that continue to hold Australia in poor international rankings. Teachers have spent 2 years getting to know the new…

The "atoms first" philosophy, adopted by a growing number of General Chemistry textbook authors, places greater emphasis on atomic structure as a key to a deeper understanding of the field of chemistry. A pivotal concept needed to understand the behavior of atoms is the restriction of an atom's energy to specific allowed values. However,…

In this article, we introduce a class of constructionist learning environments that we call "Emergent Systems Sandboxes" ("ESSs"), which have served as a centerpiece of our recent work in developing curriculum to support scalable model-based learning in classroom settings. ESSs are a carefully specified form of virtual…

Science educators and classroom teachers often present idealized descriptions of science and religion that reflect our own misunderstandings. These generalizations are often over-simplified and inaccurate and can compound misunderstandings of both domains. The first half of this paper presents an in-depth analysis of authority issues and aims to…

The recent revision of undergraduate curricular guidelines from the American Chemical Society Committee on Professional Training (ACS-CPT) has generated interest in examining new ways of organizing course sequences both for chemistry majors and for nonmajors. A radical reconstruction of the foundation-level chemistry curriculum is presented in…

The valuing of Indigenous Knowledge Systems (IKS) is one of the principles on which the South African school curriculum is supposed to be based. The purpose of this paper is to critique the treatment of indigenous knowledge in the South African secondary Physical Sciences curriculum against a backdrop of international debates on the relationship…

Calls to bring interdisciplinary content and examples into introductory science courses have increased, yet strategies that involve course restructuring often suffer from the need for a significant faculty commitment to motivate change. Minimizing the need for dramatic course reorganization, the structure, reactivity, and chemical biology…

This article reports the results of a meta-analysis of the effectiveness of 7E learning cycle in science teaching. Totally 35 different effect sizes from 24 experimental studies, comprising 2918 students were included in the meta-analysis. The results confirmed that 7E learning cycle have a positive effect on students' achievement. The overall…
