This research paper aims to propose a novel didactic sequence inspired by an historical/epistemological study of the evolution of spectroscopy and in particular of colorimetry. The working principles of the historical color comparators and the visual color matching method, first proposed by Duboscq, stimulated us in the development of a five-step…

Energy is a concept frequently encountered both in daily life and in various disciplines. Despite such a wide range of scope, conceptualizing it might be challenging at times. This study aims to investigate high school students' views on the concept of energy through a set of various paper-and-pencil tests. For this purpose, 654 high school…

The study discussed here aims to describe students' understandings of the definition of a mathematical function, which was achieved through a pilot case study of clinical interviews with four participants -- two ninth graders and two twelfth graders. The participants were recruited from the same urban public high school in the northeast of the…

When the purpose and meaning of grades is not well-defined by an organization, there is a disconnect between curricular/assessment practices and student engagement. This study sought to investigate origins and find solutions in regards to discerning a student's knowledge and mastery of a subject and how this is reflected in the grade, and how…

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…

The paper presents research that aims to expose students' understanding of the "this" reference in object-oriented programming. The study was conducted with high school students (N = 86) and college engineering students (N = 77). Conceptualization of "this" reflects an understanding of objects in general and involves aspects of…

This study aims to determine to what extent high school students are able to associate their knowledge of acid-base concepts with daily life. A form consisting of six open-ended questions was used to collect data in line with the specified purpose. Case study design, which is one of the qualitative research methods, was preferred as a method.…

We present action research of a problem posed as part of a multi-participant national (Israeli) test checking the mathematical knowledge of high school students at the ages of 16-17, where some of those who solved this problem made an error by using the converse to a well-known theorem, where the converse is not true. In order to examine the…

The purpose of this study was to investigate knowledge of high school students related to conductors at electrostatic equilibrium and electric field lines. The descriptive model was preferred in line with the purpose of the study. The sample of the study consisted of 35 11th grade students, 18 females and 16 males, who were enrolled in a…

This study investigated the use of collaborative instructional approaches on form two science students' performance in redox reactions. The sample for this study consisted of 106 science students from Winneba Senior High School in Ghana. The sample was selected from two intact classes in the school. After a pre-test organized for both classes, the…

The United States still has one of the lowest evolution acceptance rates in the world. Biology educators have been diligent in their methods to increase evolution acceptance and knowledge, with much success. However, misconceptions still arise through education, textbooks, and even social and religious settings that may influence our citizens' low…

Alternative conceptions become obstacles in physics. However, it is difficult to find instruments that can identify students' alternative conceptions, especially in gases kinetic theory (DIGaKiT). The purpose of this research was to development of diagnostic instrument of DIGaKiT in identifying students' alternative conceptions by Rasch analysis…

Climate change is the most serious environmental, social, and economic problem humanity is currently facing. Education is a fundamental pillar for societies in their efforts to address climate change, as stated in Article 12 of the Paris Agreement. In view of this imperative, the need to develop a Climate Change Education (CCE) plan that would be…

During the COVID-19 pandemic, various misinformation circulating among the public has the potential to be a source of misconceptions. This study aimed to validate the online three-tier diagnostic instrument test for Virus and COVID-19 as well as analyze the level of misconceptions experienced by students. The Treagust model is used as a reference…

The purpose of this study is to assess climate change knowledge among high school students and their beliefs and perceptions about the climate crisis. A questionnaire composed of 43 closed-ended questions was applied to 219 students aged 15-18 in three schools located in the north of Portugal. The results show that participants declared having…
