We propose discussions and hands-on activities for GCSE and A-level students, covering a fundamental aspect of nuclear physics: the concept of bonds and the energy released (absorbed) when a bond is created (broken). This is the first of the series of papers named "A teaching guide of nuclear physics", whose main goal is to provide…

This work reports a classroom experience of a general physics course designed to foster also the initiation of preservice mathematics and biology teachers to physics pedagogical content knowledge. To modify the conceptions that these students have about teaching and learning, the course was taught using different active learning instructional…

This study examines interactions of fourth graders and their parents during informal science activities to understand the parental influence on children's science interests, attitudes, and participation. Sixteen Latino/a parent-child dyads and 16 Non-Latino/a parent-child dyads, matched on socioeconomic status (SES), participated in this…

This article addresses the problem of "education for all," and offers a research proposal that replaces procedural learning by a learning practice whereby all are engaged. Although educational research since 1990 of dialogical learning (DL) and collaborative learning (CL) have shown that it is possible to promote the learning practices…

In the United States, research on beginning science teachers provides little guidance regarding empirical minimum levels of discipline-specific science coursework for sufficient subject matter knowledge to teach science. Accordingly, in this study we analyzed secondary physical science teachers' science coursework for subject matter knowledge…

Chemistry self-efficacy (CSE) was identified as a critical affective construct to predict student success in chemistry classrooms. We surveyed students at the beginning and toward the end of a semester to measure students' CSE beliefs in introductory and general chemistry courses at a Hispanic-serving institution in the United States. First, the…

Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

Nature of science (NOS) is considered an important aspect of scientific literacy. Despite efforts in guiding school students to develop more adequate NOS views, little is known about the long-term retention of students' post-intervention views. Retention of adequate NOS views is needed for functioning as scientifically literate citizens. Moreover,…

Growing class sizes and the rapid advancement of information technology have prompted institutions to implement blended learning in their academic offering. There are few reports in the literature on a holistic assessment of the effectiveness of the instructional design of blended learning courses for large classes. We defined effectiveness from a…

This study aims to investigate the main obstacles and barriers that affect Teaching Science in Saudi Universities and the Proposed Solutions during the COVID-19. The sample consists of 94 male and female students chosen randomly from different year groups in the department of science at Al-Qunfudah College at Umm Al-Qura University in Saudi…

As digital educational media use becomes more widespread, an opportunity exists to develop new methods to present abstract ideas to provide a more meaningful learning experience. Drawing from psychology and dynamic visualization research, new interactive tools can be thoughtfully designed but it is also necessary to establish how these media are…

As mobile technology becomes more frequently used in science learning, understanding the relationship between student outcomes and the technology's pedagogical features is drawing increasing attention. This study focuses on one pedagogical feature--"who led the use." We first categorized 15 specific uses of mobile technology into three…

This article reports an investigation of a professional development program to enhance elementary teachers' ability to engage their students in argument from evidence in science. Using a quasi-experimental approach, three versions were compared: Version A--a 1-week summer institute with a 2-week summer practicum experience and 8 follow-up days…

Understanding the relationship between molecular structure and function represents an important goal of undergraduate life sciences. Although evidence suggests that handling physical models supports gains in student understanding of structure-function relationships, such models have not been widely implemented in biochemistry classrooms.…

Basic Science and Technology is a subject that is based on the broad field curriculum which is the foundation for science education in Nigeria at the basic level of education. Pupils learning outcomes is usually limited to the assessment of their achievement in paper pencil test. Pupils' skills in carrying out scientific investigation and the…
