The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

Background: Electric circuit concepts in physics are abstract in nature and students find it difficult to comprehend. Purpose: This study was designed to compare the impact of three different strategies: simulation, hands-on and a combined strategy in enhancing conceptual understanding on electric circuit for class X students. Design: A mixed…

Research-based pedagogy was implemented to enhance high school students' learning outcomes in basic organic chemistry. Flipped learning and structured peer work have been offered to grade 10 students(N = 12) during the course with appropriate classroom facilities, supervised by two facilitators. The preclass and in-class activities were designed…

This study assessed teachers' understanding about the nature of scientific inquiry (NOSI) and whether this understanding was reflected in their students' responses. The data were collected through the 'Views About Scientific Inquiry' (VASI) questionnaire, a reliable tool for assessing understanding about the NOSI. The sample included science…

A 30-item questionnaire was designed to determine Omani science teachers' attitudes toward teaching science and whether or not these attitudes differ according to gender and teaching experiences of teachers. The questionnaire items were divided into 3 domains: classroom preparation, managing hands-on science, and development appropriateness. The…

This study explores how students in a joint process of knowledge construction through the use of multilingual and multimodal resources in groups promotes the learning of scientific concepts in the context of laboratory work. Inductive qualitative discourse analysis was conducted to examine how students' translanguage in a group completing tasks in…

Authentic student-led inquiry and exposure to scientific research impact students' science career choices. Given Australian students decline in STEM [science, technology, engineering and mathematics] skills, knowledge of whether such programmes impact student learning is critical. This research examined the short-term impact of an authentic,…

In this design case, we describe our work to design and develop a socio-scientific issue (SSI) based unit of instruction for use in high school biology. Our team includes university based science educators, an experienced classroom teacher, and a microbiologist. The unit focuses on antibiotic resistant bacteria as a context for student exploration…

Virtual reality environments are becoming increasingly popular as educational tools, but it remains unclear when these environments enhance learning or when they are a distraction from the learning process. We compared two different methods for teaching ecological concepts about the rocky intertidal zone by comparing an experimental (virtual)…

During the last 10 years, outreach science laboratories have become increasingly popular due to resource and time limitations in schools. Outreach laboratories offer hands-on projects in a situated and authentic learning setting, thereby promoting the development of students' scientific literacy. However, students' cognitive achievement within…

Students have access to the Internet at their fingertips via e-tablets and smart phones. However, the STEM fields are struggling to remain relevant in students' lives outside the classroom. In an effort to improve high school science curricula and to keep students engaged in the classroom, we developed a technology-rich bioengineering summer…

This study considers how students change their coherent conceptual understanding of natural selection through a hands-on simulation. The results show that most students change their understanding. In addition, some students also underwent a transformative experience and used their new knowledge in a leisure time activity. These transformative…

This research revealed that metal ions with different charges could significantly affect the viscosity of aqueous sodium carboxylmethylcellulose (CMC) solution. On the basis of an Ostwald viscometer, an improvised apparatus using a dropping ball for examining the viscosity of liquids/solutions has been developed. The results indicate that the…

The project team gathered data with the assistance of Recreational and Cultural Organization of Mashhad Municipality, Organization of Mashhad Municipality and Science and Astronomy Science Center of Mashhad Municipality, Khorasan Razavi, Islamic Republic of Iran. This paper discusses the effect of science center on attitude of students who visit…

This article describes the use of project-based instruction in activities and labs intended to develop higher-order thinking skills with high school students and pre-service teachers through the use of soap making.
