The purpose of this exploratory study was to investigate Brazilian school teacher attitudes and approaches to biodiversity education. We aim to specifically compare the amount of native biodiversity topics as measured by teachers' reports of their teaching emphasis. The study involved 147 teachers from all geographic regions of the country, who…

Literature affirms that teachers' difficulties in mastering the subject content and its teaching can be responsible for students' negative attitudes towards that subject. The present study sought to explore biology topics in the revised Rwandan curriculum which teachers have difficulties in teaching, the reasons for their difficulties, and ways to…

The digestive system is a fundamental topic in biological science teaching. Despite its importance, the level of students' knowledge on the topic appears to differ from recommended levels at several educational grades. Their knowledge also seems to be resistant to change; therefore, this discrepancy may be viewed as an epistemological obstacle to…

Students often have misconceptions about terrestrial carbon flows and there is a lack of coherence in students' explanations regarding the different levels of biological organisation at which these processes occur. In this study, problem-based teaching materials on the topic of terrestrial carbon flows were developed and tested with 15 students…

The ability to interpret and reason from Tree of Life diagrams is a key component of twenty-first century science literacy. This article reports on the authors' continued development of a multifaceted research-based curriculum--including an instructional booklet, lectures, laboratories and a field activity--to teach such tree thinking to biology…

Practical skills are important for the employability of biosciences graduates; however, first year science undergraduates often struggle to adapt to university practical classes, affecting skills development and decreasing their enthusiasm for laboratory work. This study describes the effects of introducing online multimedia practical support…

This study investigated the effectiveness of three different instructional materials for learning how to identify fish at the species level in a blended classroom and out-of-classroom scenario. A sample of 195 first-year students of biology or geoecology at the University of Tuebingen participated in a course on identification of European…

Student knowledge about plants is typically less than student knowledge about animals. Textbooks are a commonly-used curriculum material in elementary grades and contain embedded cultural ideologies that may impact instruction. This study analyzed two nationally-syndicated elementary science textbook series to explore their presentation of plant…

We examined the wildlife knowledge of primary (aged 4-12) schoolchildren. In particular, we examined the effects of children's age and gender, as well as the taxonomy and origin (indigenous versus exotic) of wildlife, on the degree of knowledge about different species. We used illustrated "flashcards" of mammals, birds and arthropods,…

Describes a science program that operates by obtaining, testing and distributing copies of computer programs among its members. (LS)

Analyzes the factors linked with the adoption of new curriculum projects by teachers for possible implications for the development of new projects. (LS)

Outlines the ecology of Lasius flavus ant hill, describes sampling techniques for the determination of the species composition of the surrounding vegetation, presents a table of typical results from an ant-hill practical, and lists suggestions for further experiments. (GS)

Describes material modified from the Nuffield advanced chemistry course to make it meaningful and relevant to pupils in the middle school. Discusses a series of simple experiments on apple browning and summarizes the browning process and its control. (Author/GS)

Discusses minimum necessary nuclear fundamentals of radioactive isotopes such as levels of activity, specific activity and the use of carrier materials. Corrections that need to be taken into account in using an isotope to obtain a valid result are also described and statistics for a valid result are included. (BR)
