Instruction plays a critical role in student success. However, most studies of teachers' effects on student learning focus on face-to-face settings. Some aspects of online courses, such as the choice of synchronous or asynchronous instruction and the course structure, might reduce teachers' influence on their students. This study of an online high…

These are the appendixes for the report, "Exploring Teachers' Influence on Student Success in an Online Biology Course." This study of an online high school biology course offered by Florida Virtual School examined the variation in students' course segment (similar to semester) completion rates, end-of-segment exam scores, and time to…

Instruction plays a critical role in student success. However, most studies of teachers' effects on student learning focus on face-to-face settings. Some aspects of online courses, such as the choice of synchronous or asynchronous instruction and the course structure, might reduce teachers' influence on their students. For example, online courses…

The present work was carried out with students of compulsory secondary education. The research was prompted by the idea that scientific vocation among young people is shrinking and that this has a significant impact on our society. Consequently, a science project based on the students' interests was proposed. They were able to work as a single…

The study investigates differentiated teaching practices of practical work in distinct social contexts and with different experienced teachers, at the level of the Portuguese high school science education. Four teaching practices were analysed in terms of the level of complexity of both scientific knowledge and cognitive skills and in terms of…

What is the future for school science and in particular for practical work? This article explores the question from four perspectives and seeks solutions for different age groups in the UK and beyond.

Sustainability has become a prominent theme in society and can be considered as an integral part of scientific citizenship. This study investigates to what extent the production, use and re-use of (bio)plastics initiates students' reasoning and to identify the kind of content knowledge students put forward. The structure of students' arguments was…

In Slovenia, as in many other countries, interest in seeking careers in science, technology and engineering-related disciplines is low, which can be recognized as a problem. The influence of general interest in biology, the content, and teaching of Biology in 9-year basic school (age 14-15) and general upper-secondary schools (age 15-18) on the…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

The study examined level of awareness and extent of utilization of innovative instructional strategies by science teachers for teaching science in senior secondary schools in Kebbi State, Nigeria. The research is quantitative in nature, descriptive survey research design was adopted. A sample of 252 science teachers was drawn from all science…

In this article, an approach to integrate contemporary quantum physics into secondary school teaching is presented. The Erlanger concept on quantum optics provides an experimental-based guideway to aspects of modern quantum physics. We avoid the traditional historical approach in order to overcome the lack of modern concepts of quantum physics. In…

While science self-concepts of secondary school students have received considerable attention, several important aspects of chemistry self-concepts have not yet been understood: gender relations, the impact of students' cultural backgrounds, and the impact of chemistry self-concept on learning processes. In the present study, (i) we could confirm…

The results of an earlier empirical research study on modifying 'step-by-step' instructions to practical activities requiring one or more steps of the experiments to be designed by students initiated a longitudinal study to investigate the effectiveness of the approach for younger students and over a period of time. The longitudinal study that…

Chemists refer to chemical phenomena on different representational levels--macroscopic, symbolic, and submicroscopic--which are directly related and connected to each other. Especially in the laboratory, students have to reason about various mechanistic features at the submicroscopic level and connect them in a meaningful way to make sense of the…

In the field of science education, laboratory learning environment has gained renewed interest in the recent decade. This study aimed to investigate the relationships among students' conceptions of science laboratory learning, perceptions of the science laboratory learning environment, and their academic self-efficacy in science learning by…
