Chromatography is the most common analytical technique able to identify and quantify a wide gamut of substances in food, environmental, forensic, pharmaceutical, and many other kinds of real samples. We propose a simple drama science activity: students embody different compounds wearing emblems of different colors and dramatize their…

The aim of this research was to provide preschool children with context-based science and nature activities and basic process skills. The research was carried out with 11 children aged 48-60 months in the second term of the 2019-2020 academic years. The research was designed according to action research, one of the qualitative research designs. In…

This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

An approach to online laboratory exercises for analytical chemistry students with demonstrated practical exercises through the use of remote-controlled gas chromatography (GC) instrumentation is discussed. The approach allows for a practical-based learning activity to be carried out by students who are unable to attend in-person laboratory…

Student engagement in math and science courses decreases starting in middle school and continues throughout high school (Museus, et al., 2011). This lack of engagement results in students taking only the required math and science coursework and not advanced coursework that would help prepare them for future careers in science, technology,…

What if you could challenge your fourth graders to create a minimally invasive, highly efficient dam? With this volume in the "STEM Road Map Curriculum Series," you can! "Hydropower Efficiency" outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines.…

Students tend to think of their science courses as isolated and unrelated to each other, making it difficult for them to see connections across disciplines. In addition, many existing science assessments target rote memorization and algorithmic problem-solving skills. Here, we describe the development, implementation, and evaluation of an activity…

Design activities can serve as a concrete experience to address the similarities and differences between science and engineering, and also demarcate engineering from tinkering. They can lay the foundation for concept development of targeted disciplinary ideas. Minor, but crucial, changes to classroom tinkering activities along with targeting and…

Stimulating interest in science at an early age is important for STEM education. This work details an educational activity utilizing the anthocyanins found in butterfly pea flowers ("Clitoria ternatea"). This activity was developed for use in official classroom settings, online, and/or at-home with parental or educator guidance. Primary…

Interactive digital technologies are playing an increasingly important part in education for enhancing collaborative learning processes and improving engagement. Social annotation (SA) tools and collaborative platforms are an innovative way to involve students to give and take feedback, annotate, and brainstorm on complex topics in science,…

This study aims to reveal the effects of out-of-class learning activities conducted in the school garden on students' interest in science and their scientific attitudes. Research designed as a pretest-posttest control group quasi-experimental design of quantitative research methods. The research group of the study consists of 37, 7th grade…

The activities designed by 91 teams of primary teacher education students as part of their teaching proposals in a course on science teaching are analysed together with the subsequent reformulations of those activities. The objective of the study was to gain insight into the students' professional practical knowledge and the underlying focus of…

In the current study, an engineering design-based STEM activity was designed and implemented for 5th graders. The current activity is expected to provide guidance and perspective to teachers (practitioners) in designing and implementing an activity based on design-based learning, STEM activity, and engineering design process (EDP). At the same…

Early science learning has the potential to enhance children's social interaction development, but a lack of resources in schools requires well-structured activities and a supportive learning environment. In a project aimed at helping children develop an interest in science education from an early age, this describes a Project-Based,…

High-quality instructional interaction, in which teachers engage children in conversations that support the development of higher order thinking skills, conceptual understanding, and advanced language skills, is associated with positive outcomes for preschool children. Classrooms serving low-income preschoolers tend to have lower levels of this…
