General Chemistry is a course where students are expected to nurture the development of their fundamental concepts in chemistry. Students begin general chemistry with alternative conceptions about the topics and fragmented knowledge structures. Majority of students who successfully complete the general chemistry course sequence continue to hold…

An empirical investigation of elementary school teacher candidates on classification activities dealing with animate and inanimate objects in terms of being living or non-living demonstrates that as the size of the objects increases, subjects are more likely to classify them correctly as either being an animal or having living characteristics.…

Enhancing students' understanding of aspects of the nature of science (NOS) recommended by the science education community is an important goal of science instruction. This can occur only when teachers are adequately prepared for teaching NOS. However, the science education community is still considering what is needed to enhance the efficiency of…

Although the promotion of students' language proficiency is an objective of all school subjects, many physics teachers self-evidently expect their students to apply sophisticated language repertoires. We assume that this expectation affects how physics teachers assess students' texts in a classroom assessment. More precisely, we suppose that…

In order to investigate the impact of science drawing instruction in a first-grade unit on carnivorous plants (CPs), we analysed student-produced drawings after explicit instruction in drawing scientifically (n=38), as well as compared their drawings with students in a previous implementation (year 1) who did not experience explicit drawing…

This study aims to introduce inquiry-based play activities and to examine their effectiveness on young children's conceptual understanding of the shape of the Earth and the day-night cycle. The inquiry-based play activities for preschool children were designed to support children to learn the concepts of the shape of the Earth and the day-night…

This study investigated the perceptions and quality of argumentative and summary writing of the Pre-service Science Teachers (PSTs) who participated in a knowledge generation approach to learning, which is known as the SWH approach, and who had had experience with it across different time periods. A total of 41 PSTs were divided into three groups…

Previous studies have pointed to the benefits of involving students' everyday life experiences in lessons and in contextualizing the science content to enhance learning and positive attitudes toward school science. However, most of these investigations have been conducted as intervention studies. By contrast, the present study explored how…

What does a scientist do? What is an engineer? What is technology? What do mathematicians do? Questions about the nature of STEM are fundamental to help elementary students gain a deep understanding of the STEM disciplines. Yet, starting a lesson with such abstract questions can be difficult for any learner. Instead, teachers can use concrete STEM…

The study was conducted to identify the needs and specifications of a STEM Module based on a game approach in teaching science for lower secondary school students. In this study, the needs analysis was carried out on purposively selected science teachers from different schools in the northern district of Kedah, Malaysia. The data was collected…

Physics lab instructors were forced to adapt their courses in 2020 due to the COVID-19 pandemic. We investigate the impact these changes had on student views towards experimental physics as measured by the Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS). Analysis of the responses from over 1600 students in both…

Lewis structures are a very important, foundational concept in chemistry. Students usually acquire this knowledge in General Chemistry and need to review it in preparation for Organic Chemistry. However, many students find the task of drawing Lewis structures to be challenging, and not all instructors can budget enough time in class to review this…

Dual language learners are a steadily growing student population in several countries, including the United States -- and especially in early childhood. Consequently, any efforts to develop strong early childhood programming must include practices which support multiple areas of DLLs' development. From a domain-specific lens, I synthesize the…

The purpose of this study is to investigate the self-efficacy levels of pre-service science teachers who participated in a workshop about physical laboratory implementations supported by digital simulations and also to determine their views on digital simulations. For this purpose, a 6-week workshop was designed based on a digital simulation…

Students in advanced undergraduate chemistry laboratories are required to undertake a wide range of complex and multistep syntheses and analytical procedures, and prospective employers of chemistry graduates seek students with proven skills in these areas. Our approach has been to use video resources which are made available to students both ahead…
