The concept of oxidation state (or oxidation number) and related issues have always been difficult for students. In addition, there are misunderstandings and obscurities, which can cause improper balancing of the chemical equations (mostly in organic reactions). In particular, these problems are related to determination of the oxidation state of…

In everyday praxis, we often need demonstration measuring devices (thermometers, pH meters, etc.), with large enough displays to be easily readable from every point in the classroom. Here, we present some of the capabilities of the Arduino platform for the school environment. This microprocessor board can be used for inexpensive construction of…

The paper reports a study of the effectiveness of co-teaching and co-generative dialogue in science learning and teaching in lower secondary science classes. The idea of co-teaching and co-generative dialogue--first proposed by two leading educationists, Roth and Tobin, in early 2000--made an international impact in educational research. In the…

The galvanic cell presented in this article is made of only three parts, is easy to assemble, and can light a red light emitting diode (LED). The three cell components consist of a piece of paper with copper sulfate, a piece of paper with sodium sulfate, and a piece of magnesium ribbon. Within less than 1 h, students have time to discuss the…

Though an adequate understanding of content is a natural prerequisite of teaching (Carlsen in "Journal of Research in Science Teaching" 30:471-481, 1993), teachers also need to be able to interpret content in ways that facilitate student learning. How to best support novice teachers in developing and refining their content knowledge for…

In this paper, it is aimed to analyze the acquirements and topics in Turkish secondary school history textbooks that are published by the Ministry of National Education (MEB) and by the private sector to determine to what extend the place given to history of science and history of medicine. In the study, the document and content analysis…

This study established the effects of a web-based computer simulation on the conceptual understanding of the rate of chemical reaction and attitude of 66 first year secondary school (SS1) students in Niger state, Nigeria towards chemistry. A pretest and post-test experimental design was used during which students were randomly assigned into either…

The aims of this study were to investigate the relationship between the Palestinian secondary school students knowledge level of science process skills and their attitudes toward science, and the effect of gender and residence of these students on their knowledge level of science process skills and on their attitudes toward science. The study used…

The study investigated the impact of virtual laboratory on the achievements of secondary school chemistry students in homogeneous and heterogeneous collaborative settings in Minna, Niger state, Nigeria. Three hypotheses were formulated, analyzed and tested at 0.05 alpha level. Stratified sampling technique was used to select 60 Senior Secondary…

The Whole School Success Partnership (TWSSP) worked to develop practices and cultures that emphasized student success in five middle and high schools. Because this project took place in secondary schools where teachers have disciplinary specializations, the whole school approach came with unique opportunities and challenges. Here we describe how…

This article is drawn from a study conducted to explore how assessment conversations, a type of informal formative assessment, can support science learning in a technology-aided seventh-grade classroom in Northern California. The classroom setting where the study took place used interactive whiteboards in conjunction with the inquiry-based…

The 2015-16 Civil Rights Data Collection (CRDC) is a survey of all public schools and school districts in the United States. The CRDC measures student access to courses, programs, staff, and resources that impact education equity and opportunity for students. The CRDC has long provided critical information used by the Department of Education's…

Culturally responsive science teaching has been associated with several positive academic outcomes for students of color, including improved science achievement, attitudes, and identities. Given the chronic science performance gap between students of color and white peers, culturally responsive teaching seems ideal for mitigating this disparity.…

In this research; aim was determining student achievement by comparing problem-based learning method with teacher-centered traditional method of teaching 10th grade chemistry lesson mixtures topic. Pretest-posttest control group research design is implemented. Research sample includes; two classes of (total of 48 students) an Anatolian High School…

This mixed methods study investigated high school students' evaluations of scientific arguments. Myside bias occurs when individuals evaluate belief-consistent information more favorably than belief-inconsistent information. In the quantitative phase, participants (n = 72 males) rated belief-consistent arguments more favorably than…
