A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

In this paper we discuss different ways teachers can integrate science and mathematics into their curriculum. In particular, we focus on science and mathematics integration via the disciplinary practices.

In this study, a process was designed, in which a lemon seed grew into a seedling, using the inquiry-based science learning approach. This aimed to increase the overall development of the scientific process skills of children and their sensitivity to nature. The germination, growth and development of a plant were meticulously and systematically…

Background: This study presents the development of three research tools of scientific creativity. Our aim is to evaluate the development of student creativity while students write digital stories. Three models are linked to create a new model, called Creative, Cognitive, Qualitative Model for Creativity (CCQ tool). Our research tool examines how…

Despite the importance of scientific inquiry in science education, research has shown that pre-service teachers have deficiencies in terms of knowledge and skills. This study aimed to improve pre-service teachers' science process skills and views about scientific inquiry through inquiry-based activities. This study was carried out with one group…

The mental models students have after engaging in an activity designed to teach infrared (IR) spectroscopy without reliance on IR absorption tables, were characterized. Qualitative analysis of semi-structured interviews, through open coding, allowed the classification of the mental models as Molecules as Dynamic (MAD), Bonds as Dynamic (BAD),…

The Next Generation Science Standards list scientific argumentation as one of the essential skills for students in K-12 education. Unfortunately, many teachers enter the classrooms without sufficient experiences with or knowledge of, this skill. A discourse analysis of twenty-one preservice teachers was conducted to study how preservice teachers…

For years, inquiry-based learning has been conceived of and promoted as one of the best approaches to learning science. However, there is currently a movement within the science education community that suggests promoting science learning based on scientific practices, instead of inquiry, because in this way, science learning would be more…

Knowledge construction is an essential scientific practice, and undergraduate research experiences (UREs) provide opportunities for students to engage with this scientific practice in an authentic context. While participating in UREs, students develop conceptualizations about how science gathers, evaluates, and constructs knowledge (science…

Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

A large number of articles in the field of science education reflect on scientific literacy as the main goal of science education (SE), although often with varying viewpoints. Nevertheless, researchers have begun to highlight subject-specific teaching practices that are expected to specifically enhance science subject teaching, including biology.…

Enzymes are widely applied in different industries, like pharmaceutical, food, biofuel, and waste valorization. However, the enzyme operating conditions are very limited. So, in most industrial processes, enzymes are not efficient, due to the use of harsh conditions, like organic solvents, extreme pH, and temperature. Immobilization arises as a…

This study is the result of a quantitative analysis of the previous paper reporting on four cases in which an LED is turned on by charge transfer occurring during the electrostatic induction process in a conductor connected to the LED. We were able to measure the charge transfer by using charge sensors and analyze experimental results by applying…

Science process skills play an essential role in science education. The research assessing these skills in school science textbooks is limited. The aim of the current study was to examine the involvement of science process skills in the content of science school textbooks of the last two primary school grades in Greece. A specific analysis…
