Three projects that use evidence- and research-based practice to engage and support three under-served audiences -- children with special educational needs (Science Hunters -- Lancaster University), young carers (Young Carer Chemistry Workshops at Cotton On -- Science from the Start) and girls and women in engineering (Women Like Me -- UWE…

Presents a modern Periodic Table based on the electron distribution in the outermost shell and the order of filling of the sublevels within the shells. Enables a student to read off directly the electronic configuration of the element and the order in which filling occurs. (JRH)

Presents a causal mechanism linking models to learning in order to establish whether or not good models are good for teaching. (MKR)

Presents an activity to determine whether the radioactivity of a pure potassium salt is directly proportional to the amount of potassium in it and whether this could be used as a method of analysis for potassium in a solid. (MKR)

"Ccore charge" is a fundamental concept that explains a wide range of phenomena. Suggests that this concept, while abstract, has the potential to make chemistry much simpler for learners. (MM)

Describes an activity which presents the reactivity of metals series as a football pool with more reactive metals at the top of the table and unreactive metals at the bottom. Describes how the activity can be applied in different ways for different ability groups. (Author/MM)

Reports effectiveness of team teaching methods in chemistry for mixed ability groups using worksheets, time flexibility, and staff involvement for evaluation of individual student progress. (CS)

Recommends materials and makes suggestions for using information and communication technology (ICT) as a tool to support chemistry teaching and learning both in and out of the classroom. While the approaches are geared specifically towards teaching chemistry across the 11-18 age range, they are easily transferable to other subject areas.…

Describes the use of Venn diagrams in chemistry. (MKR)

Describes a study of the ability of fourth-year university student-teachers to use their theoretical knowledge of redox concepts to interpret natural phenomena of everyday life. Uses word-association tests, multiple-choice and open questions and reports that the students have difficulties in recognizing the scientific nature of well-known everyday…

Identifies the misunderstandings and problem-solving strategies of secondary students when solving stoichiometry problems. (Author/CCM)

Last in a series, this article focuses on reporting and using the outcomes of the examination for the Nuffield Advanced Chemistry Project. Discusses accuracy, reliability and validity estimates, and curriculum validity; provides detailed information about student attainment. Roles of examinations in evaluation and development of school curricula…

Described are panning and jigging methods of performing chemistry experiments and demonstrations to illustrate physical separation, location, identification, and concentration of minerals. (SL)
