The study aimed to investigate the effect of authentic problem-based learning (PBL) activities in the unit of "Human and Environment" on 7th graders' environmental information, their reflective thinking skills and their environmental attitudes. The sample of the study consisted of 53 7th grade students from two different classes…

Afterschool interventions in STEM are linked to learning gains during the school day. These opportunities engage and excite students about STEM concepts since they observe a more hands-on, project-oriented approach. Often these opportunities for afterschool interventions are infrequent in nature and leave gaps for students in their maturation and…

Research related to teaching climate change, system thinking, current reform in science education, and the research on reform-oriented assessment indicate that we need to explore student understanding in greater detail instead of only testing for an incremental gain in disciplinary knowledge. Using open-ended items we assessed details in student…

This study examined the effects of using "Physical Best" lessons to promote adolescent energy balance knowledge and task values. Seventh graders (N = 90) were randomly assigned to the experiment and the comparison groups. The experiment group took 10 selected "Physical Best" lessons, while the comparison experienced 10 district…

Many studies have shown that students at different age levels come into classrooms with a variety of alternative conceptions. Commonly held alternative conceptions are the main source of the difficulties that students and teachers face in learning and teaching. The aim of this study was to compare the conceptual understanding of students who were…

The overall objective of this study is to increase the awareness of secondary school students of the effects of pollen allergy on human health by mapping allergic pollens appearing in Burdur atmosphere. This study is a pre-test and post-test experimental design. Mix method is applied thus. Both qualitative and quantitative data are gathered. The…

Statistics is an increasingly important component of the mathematics curriculum. "StatSmart" was a project intended to influence middle-years students' learning outcomes in statistics through the provision of appropriate professional learning opportunities and technology to teachers. Participating students in grade 5/6 to grade 9…

Background: The purpose of this study is to compare the effectiveness of a national comprehensive teen pregnancy prevention (TPP) intervention to a national abstinence-only TPP intervention on middle school students' knowledge, attitudes, and behaviors related to teen sexual behaviors in a state with high teen birth rates. Methods: Pre- and…

Purpose: The purpose of this paper is to assess whether the school-based nutrition programme using the health-promoting school (HPS) framework was effective to improve parents' knowledge, attitudes and behaviour (KAB) in relation to nutrition in rural Mi Yun County, Beijing. Design/methodology/approach: A cluster-randomised intervention trial…

Besides viewing knowledge about the nature of science (NOS) as important for its own value with respect to scientific literacy, an adequate understanding of NOS is expected to improve science content learning by fostering the ability to interrelate scientific concepts and, thus, coherently acquire scientific content knowledge. However, there is a…

Thus far, it is unclear how students can learn most effectively from their own errors. In this study, reflections on the rationale behind self-made errors are assumed to enhance knowledge acquisition. In a field experiment with pre/post/follow-up design, the authors practiced fractions with 174 seventh- and eighth-grade students who were randomly…

It is important to structure children's knowledge and arouse their interest in subjects like astronomy and space. Although we now talk of travelling to the moon, space tourism etc., knowledge about astronomy and space is limited and perceptions of these subjects do not reflect scientific reality. Primary level students often have misconceptions…

Background: Density is difficult to learn and teach in middle schools. This study, hypothesizing that the density concept develops as part of a conceptual system, used a conceptual change approach to teaching density. The approach emphasized the use of multiple strategies to teach the density concept and the associated concepts in the conceptual…

In the course of inquiry activities similar to those of real scientists, learners are supposed to develop knowledge both on the level of observable phenomena and on the level of explanatory theories. However, some theories involve theoretical entities (e.g., "Weiss domains") that cannot be observed directly and therefore may be hard to…

The purpose of this study was to examine the association of middle school student science achievement and attitudes about science with student-reported frequency of teacher lecture demonstrations and student-centered learning. The student sample was composed of 602 seventh- and eighth-grade students enrolled in middle school science. Multiple…
