The greenhouse effect is a complex scientific phenomenon that plays a crucial role in understanding climate change. Grasping students' understanding of this phenomenon on the content-specific level but also how students' conceptions are organized is vital for effective climate change education. This study addresses both levels and delves into the…

This article focuses on the learning of the Lewis representation at the transition from high school to university, in France. Indeed, this notion is taught both in high school and in the first year of higher education but with different methods, which seems to hinder the learners. In this work, we observe 11th grade and higher education classes…

In this research, it was aimed to analyze the problem solving strategies used during solving problems related to constant speed and constant acceleration motion, which are often used in graphs, according to the presentation of the problem (text and graph). The research was carried out with 119 students studying in the 11th grade. In the research…

Response to the continuing call to integrate scientific inquiry activities into high school education has taken different forms varying in student ownership, physical setting, time span, and mentoring resources. Important issues are how students perceive central dimensions of their experience, and the extent to which the inquiry framework design…

Inquiry skills are one of the skills that students need to master in learning biological concepts. Inquiry skills are influenced by many factors, one of which is the lesson plan. This study aims to examine the effect of inquiry lab and STEM models on inquiry skills progression. The research design used was a quasi-experiment non-randomized control…

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity,…

This study focuses on examining the mental models of 11th and 12th-grade students attending a science high school in Turkey regarding the concept of the electron cloud. The study involved 72 students and employed the case study method. The precondition for selecting the sample was that the students had covered the unit on modern atomic theory in…

There is increasing recognition of the importance of learning contexts in science education. However, learning contexts are rarely articulated in terms of what they constitute and are often framed by educators and textbooks with limited inputs from students. Unless properly articulated, contexts become anything and everything, thereby losing their…

This research aims to analyse students' conceptual understanding of chemical equilibrium matter using Physics Education Technology (PhET) Interactive Simulations. Students' misconceptions can be caused by the difficulty in connecting the sub-microscopic, macroscopic, and symbolic levels of understanding in chemistry. The study was conducted at a…

The aim of this qualitative case study was to explore secondary students' ability to transfer among representation levels in relation to stoichiometry. In the study, 40 students in the 11th grade from two classes of an Anatolian high school in the east part of Turkey were selected as sample group. The data were collected by using a questionnaire…

Multiple representations are widely recognized for their significant role in concept learning. This study aimed to investigate the multiple representation translation skills of high school students at different grade levels about the concept of one-dimensional motion. 239 9th, 10th, and 11th-grade students participated in the study using a…

Allowing students to practice science inquiry in the classroom is fundamental for science education. Students should master investigation skills, promoting their understanding of science concepts. Virtual laboratories have emerged as a powerful interactive tool that can be a suitable alternative to real laboratories, especially when lacking enough…

This study aimed to capture the development of interaction among the components of pre-service chemistry teachers' enacted PCK throughout the school experience course. Data were collected from four pre-service teachers using content representation (CoRe), observations, field notes, and semi-structured interviews. Secondary analysis was conducted…

Ecological literacy (Eco literacy) along with creative thinking skills can be utilised to overcome environmental problems to achieve environmental sustainability. This research analyses the correlation between ecological literacy and students' creative thinking skills of environmental problems. The research method is quantitative with a…

Evidences showed that students' chemistry learning outcomes were still low. One of the causes was the chemistry practicums carried out so far were traditional chemistry practicums. Therefore, it needed to be reoriented towards the practicum. Thus, this study aimed to investigate the effect of green chemistry practicums on students' learning…
