This study is a part of a large scale project in which an action research design is used to teach proof to 11th grade students. This part of the project aims to identify students' comprehension level through five proof comprehension tests developed by the researchers based on the National Geometry Curriculum. Data were analyzed by considering the…

This study investigated the association between school-based health centers (SBHCs) and sexual behavior and contraceptive use among 11th graders. The sample included 134 high schools (27 schools with SBHCs) and 11,840 students who participated in the 2015 Oregon Healthy Teens Survey. Multilevel logistic regressions found positive associations…

The objective of this article is to analyze the perception of secondary school students of their social science class in three different Colombian educational institutions. It is important to identify the significant aspects valued by students concerning their experience in the aforementioned class and to describe analytically the meaning that…

This study aims to test the effects of essay tests and learning methods on students' chemistry learning outcomes. The sample of this study was drawn from grade 11 students at Jambi State Senior High Schools through a multi-stage random sampling technique. Within a factorial experimental design, the data were analyzed using the covariance analysis…

The relationship between student activity data and performance in the online classroom is well-documented, yet the parameters of this relationship and their implications for K-12 online schools are not yet well understood. This study examined the role of student chronotype (defined here as the time of day a student is most active in an online…

Ongoing changes in mental and personal characteristics of the modern child initiate the updating of means and forms of education. And they, in their turn, update methodological techniques and approaches to the use of methods during the math class. The source of updating methodological techniques may be the principles used when solving scientific…

Moral development in gifted education is an issue of imperative importance due to the potential of gifted students to change the world. In consideration of this issue and the lack of research on the topic, this study examined the extent to which moral development was present within the senior secondary English curricula at an academically…

Results in Mathematics Education, from different theoretical perspectives, highlight students' difficulties with graphs, both in interpreting given ones and in producing their own graphs. In this paper, we take an affective lens to understand both a student's relationship with mathematical graphs and a teacher's role when a task with a graph is…

The barriers to education associated with menstruation vary from country to country and within countries.

Furthermore, no test exists to assess students' proficiency in (a broad range of) research skills in a…

Studies on student learning of scientific concepts have shown that students often experience various difficulties in understanding basic physics concepts such as vector quantities, as a result of formal and informal learning. The purpose of the present study is to document Grade 11 students' difficulties in understanding vectors and their…

This paper examines mathematical meaning-making from a phenomenological perspective and considers how a specific dynamic digital tool can prompt students to disclose the relationships between a function and its antiderivatives. Drawing on case study methodology, we focus on a pair of grade 11 students and analyze how the tool's affordances and the…

Drawing inference from data is an important skill for students to understand their everyday life, so that the sampling distribution as a central topic in statistical inference is necessary to be learned by the students.
