There are hundreds of satellites in orbit around Earth. Readily available data about them can be a treasure trove for investigations by students at all levels. Orbital parameters and energy changes can be explored. Many of these satellites transmit signals that can be detected by an inexpensive radio receiver--a scanner--designed to receive FM…

We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as…

Studies have shown that inadequate definitions of scientific concepts could complicate the learning of science and could prevent students from understanding the definitions of scientific concepts. The article provides a framework for defining scientific concepts in primary, secondary, and university education by proposing teachers draw attention…

An inquiry approach to learning can have a positive impact on students' attitudes to science and their science literacy skills; two attributes that have been in steady decline internationally. The professional development of teachers in inquiry science is one way to ensure that teachers are equipped with effective strategies to teach science,…

Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

This study was conducted on the perception of high school students regarding the influence of learner and teacher on school science learning. The subjects were 867 South Korean high school students at 464 natural science and 404 humanities learning course. The components of the influence of learner and teacher on school science learning consisted…

This paper investigated constraints associated with biology teaching and learning materials in selected schools in the Central Region of Ghana. The purpose of this study was to evaluate the classroom implementation of biology curriculum. A cross-sectional descriptive survey design was used for the study. The target population comprised 187 biology…

This research is part of the integration of information and communication technologies (ICT) in the Moroccan education system, our objective being to evaluate the use of computer-assisted experimentation (CAEx) in learning to encourage the authorities of the Ministry of National Education, Vocational Training and Sports to adopt the CAEx program…

Course-based undergraduate research experiences (CUREs) are being increasingly implemented to broaden the opportunities for undergraduate students to engage in authentic research across STEM disciplines including chemistry. The present review synthesizes the literature on chemistry CUREs, encompassing 68 articles published between 2016 and 2022…

Science teacher's self-efficacy has been at the center of many investigations on students' achievement in science, teacher burnout, and teacher performance. While overly studied, this construct has not been examined with scientific literacy in depth. Thus, this study aims to identify the influence of science teacher's scientific literacy on their…

Nine years after reconceptualizing the nature of science for science education using the family resemblance approach (FRA) (Erduran & Dagher, 2014a), the time is ripe for taking stock of what this approach has accomplished, and what future research it can facilitate. This reflective paper aims to accomplish three goals. The first addresses…

The purpose of this study was twofold: first, to investigate science teachers' views about the nature of science (NOS); and second, to examine science teachers' views about their NOS integration into instruction. Reconceptualized family resemblance approach to nature of science (RFN) is used as a theoretical and analytical framework. The…

This study investigated how an intervention consisting of a series of physical science lessons embedded within the elementary science methods course impacted elementary preservice teachers' (N = 473) science content knowledge as evidenced in their scaled scores for the science content component of a standardized subject certification examinations…

The paper presents a study that aimed to reveal the process quality descriptors of an argument-based inquiry approach. Process quality signifies whether a teacher is a better or unsatisfactory implementer of a version of in-class science inquiry. An experienced middle school science teacher was the participant. Based on the initial analysis…

Out-of-school science learning environments enrich classroom education in many countries around the world. Numerous studies have been conducted on the effects of such learning environments, particularly their ability to promote interest. As different theories of interest were used in these studies, so far, no overview of this field of research…
