Although saliva has commonly been used to teach about digestion by organisms, the phenomenon of digestion is actually caused by enzymes as catalytic substances. This activity explores the hydrolysis of starch by "a"-amylase in cleaning materials as well as a comparison with the similar reaction using human saliva. The fact that the…

This study developed an online observable augmented reality dynamics experimental system that can be used in the current COVID-19 pandemic, where face-to-face experiments are difficult to conduct. The developed system enables the broadcast of mass point and rigid body measurements using an online depth camera, and remote observation using mobile…

The 'Moss Safari' activity was developed to assist with knowing which organisms to look for when observing a drop of water squeezed from moss for the first time. In this case study, the activity was introduced online to 34 trainee science teachers. This was followed by a post-session questionnaire evaluating their experience of the Moss Safari.…

This article provides a first-hand account of the author's experience realizing that her high school science students, many of whom were students of color, were not engaged in learning in her classes and how she learned about and put into practice more culturally sustaining and relevant pedagogies.

Physics phenomena are widely viewed in daily life, and the technical nature of physics makes modern life seem to be simpler than it was many years ago. Physics teaching and learning, on the other hand, has not always been done effectively, especially in developing countries. This study aimed measured the effectiveness using mobile physics on…

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…
