This study investigates the development of Topic-Specific Pedagogical Content Knowledge (TSPCK) of 14 novice uncertified graduate science teachers during a Professional Development Intervention (PDI) on teaching particulate nature of matter. TSPCK was defined in terms of five knowledge components: learner prior knowledge, curricular saliency,…

Energy is one of the most complex yet central concepts taught in schools and is featured in the Australian Science Curriculum, as one of the six key organising ideas (Australian Curriculum, Assessment and Reporting Authority (ACARA), 2015). The literature portrays a multitude of complications associated with teaching energy (see Millar, 2005 for a…

As solar energy becomes increasingly affordable, many schools are considering installing new solar power systems. In this article, the authors present Solarize Your School, an engineering project that gives students the opportunity to design and evaluate solar power solutions for their own schools. This STEM project requires students to learn and…

The decline in students' interest in science and technology is a major concern in the western world. One approach to reversing this decline is to introduce modern physics concepts much earlier in the school curriculum. We have used the context of the recent discoveries of gravitational waves to test the benefits of one-day interventions, in which…

Chemical bonding is a fundamental but complex topic, which has traditionally been associated with learning difficulties, misunderstandings, and misconceptions. This paper reviews some previous studies, concerning students' conceptual difficulties and reports the findings from a research study with Greek students, which set out to examine their…

Despite the number of university students who take courses in multiple science disciplines, little is known about how they perceive common concepts from different disciplinary perspectives and to what extent they recognize connections among their courses. This dissertation explores students' perceptions of their chemistry and biology courses…

English Language Learners (ELL) students are a growing population in Texas schools. Due to language barriers and lack of comprehensiveness in a secondary science classroom, ELL students may have difficulties comprehending higher-level secondary science concepts. While staff development workshops have the objective of ensuring teachers are…

The purpose of the study is to evaluate the effects of chemistry activities applied in summer science camp on secondary school students. Action research was used in the study as the method. The sample of the study consists of 48 7th grade students who study at elementary school in Çayeli district of Rize province, in Turkey. Each week 24 students…

The present study examined to what extent inquiry-based investigation as an instructional approach associated with students' overall science achievement and achievement in cognitive domains, including knowing science facts, applying scientific principles, and reasoning with scientific concepts to solve problems. Using TIMSS 2007 science…

The purpose of this study was to investigate the alignment between the fourth-grade summative classroom assessments and the 'Matter and Energy' unit in the Lebanese science curriculum using: content and cognitive levels. Summative assessments were collected from a sample of 17 schools. The alignment between the classroom assessments and the…

We present the design, statistical analysis, and validation of a questionnaire to assess students' knowledge about basic aspects of quantum mechanics (QM). The QM evaluation (QME) is a true-false and multiple-choice mixed questionnaire that features 10 two-tier items spanning three relevant themes in quantum mechanics: wave behavior of matter,…

Even though it has been shown that retrieval practice could foster deeper learning and better long-term retention in other domains such as psychology, it is rarely studied in the context of physics learning where students need to solve more complicated problems. To an even lesser degree is comparing retrieval-based learning with other active…

The science education approach has covered by using printed teaching media. One of the popular printed press that most accessible and may used in science education is a comic book. However, it is sometimes difficult to find the ideal and the appropriate comic books that can be used as the instructional tool of science education, because most of…

Learning about heredity is important across the K-12 continuum. However, these ideas may be challenging for students. We examined third-grade students' ideas about heredity in the context of a new, six-week, model-based science unit that uses corn as a model organism to support students' ideas about heredity. We analyzed data collected during…

There has been a call from the national community of biologists and biology educators to increase biological literacy of undergraduate students, including understanding and application of core concepts. The structure and function relationship is a core concept identified by the wider biology community and by physiology faculty. Understanding of…
