The changeover of the Kenyan system of education from the 7-4-2-3 to the current 8-4-4 in 1984 made science subjects (Biology, Chemistry and Physics) compulsory to all students up to form two at the secondary school level. This meant increased numbers of students in one class at a time attending the science subjects, which may compromise quality.…

We developed an interactive exercise to teach students how to draw the structures of the 20 standard amino acids and to identify the one-letter abbreviations by modifying the familiar game of "Hangman." Amino acid structures were used to represent single letters throughout the game. To provide additional practice in identifying…

This paper presents a simplified approach for the application of material efficiency metrics to linear and convergent synthesis plans encountered in organic synthesis courses. Computations are facilitated and automated using intuitively designed Microsoft Excel spreadsheets without invoking abstract mathematical formulas. The merits of this…

The number of students majoring in science, technology, engineering, and math (STEM) is declining due in part to a lack of student interest (Fairweather 2008; NRC 2012; PCAST 2010). One reason may be the difference between how science is done in school and how it is done in the field (Osborne, Simon, and Collins 2003). An interdisciplinary…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

This article describes how a university and a museum have worked together to create a "How science works" workshop entitled "What's in our water?" The workshop teaches students about the continuing pollution from a disused coal mine, how the pollution is cleaned up using a state-of-the-art treatment works and how scientists…

Despite being criticised for placing little emphasis on thinking, the majority of laboratory work at school level is taught "via" expository "recipe-style" labs. This has been seen to result in students struggling to be able to apply the practical techniques they have learnt in the classroom outside the narrow environment in which they were…

The objectives of this research were to identify the characteristics and effectiveness of chemistry teaching programs that increase students' entrepreneurial attitudes, chemistry concepts understanding and creativity. The research design application refers to the R & D (Research and Development) Design. Seventy-three senior high school students…

This study describes the analogical models and narratives used to introduce and teach Grade 9 chemical covalent compounds which are relatively abstract and difficult for students. We explained each model's development during the lessons and analyzed understanding students derived from these learning materials. In this context, achievement,…

There exists a general consensus in the science education literature around the goal of enhancing learners' views of nature of science (NOS). An extensive body of research in the field has highlighted the effectiveness of explicit NOS instructional approaches in improving learners' NOS views. Emerging research has suggested that engaging learners…

The growing popularity of computer and network technologies has attracted researchers to investigate the strategies and the effects of information technology applied instructions. Previous research has not only demonstrated the benefits of applying information technologies to the learning process, but has also revealed the difficulty of applying…

Contains contributed suggestions in the teaching of structure and bonding and reaction rates and equilibria in the Nuffield Advanced Chemistry Project. (CP)

Describes a functional management system which individualizes instruction in undergraduate chemistry courses. CHEM TIPS (Chemistry Teaching Information Processing System) is designed to monitor each student's progress, identify specific weaknesses and strengths in his understanding of the course material, prescribe individual study assignments,…

Presents the author's reasons for supporting the CHEMS program. Also characterizes aspects of his teaching regarded as significant in teaching chemistry, including prompt return of assignments, test retakes, videotaping. inclusion of organic chemistry, ability grouping of students, avoidance of specialization, and departmental testing. (CS)

Whether for use in a special methods course in teaching chemistry or a general methods course in teaching science, this guidebook is designed to assist the methods instructor in the task of fitting the ChemSource materials into the established patterns of the course. Each of three sections contains a number of units that accommodate the patterns…
