Clear, detailed instructional procedures have an important role to play in laboratory teaching to not only produce consistent results but also ensure safe practices. Student success in using these procedures can be strengthened through the use of video resources. However, not all video content will have the same impact. Videos must have sufficient…

In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism.…

Research on teacher educators' professional learning has gained increasing interest within science education. Curriculum materials have been suggested as a means of supporting "teacher" learning for several decades but have not yet been examined as a potential tool for supporting the learning of "teacher educators." In this…

The technical barriers to video production are decreasing and the popularity of video as an instructional medium in science is increasing. Although a large body of education research is available to inform the selection and design of instructional videos, this research is dispersed across journals, disciplinary traditions, and STEM fields, and the…

Successful implementation of historical approach to teach nature of science (NOS) requires suitable curriculum material. Several research and development projects have produced lesson plans for science teachers. 25 lesson plans from four different projects involved in creating curriculum material utilizing historical approach in chemistry…

Parents can play a vital and active role in facilitating their children's science learning outside the formal classrooms. Parental involvement in their children's science learning process not only could enhance their children's learning motivation and interest in science, it could also help to strengthen the family bond when parents and children…

Teachers need to develop the ability to adapt curriculum materials. Two elementary teachers, Maggie and Catie, were asked to write narratives about their use of and changes to particular reform-oriented science lesson plans. Maggie drew on her knowledge of and experiences with students, as well as other knowledge, experiences, and resources, to…

The features and the development of various new acids and bases activity sets that combines chemistry with nanotechnology are being described. These sets lead to the generation of many nanotechnology-based pharmaceuticals for the treatment of various diseases.

Discusses the use of property diagrams as an instructional tool to help students understand and visualize important, complex thermodynamic relationships. Also discusses the approach used in preparing these diagrams, which were computer-generated as part of graduate students' research. (JN)

Describes basic misconceptions about the origin of elements and forms of matter found in chemistry texts that need modification in light of modern observational data and interpretations given in astronomy. Notes that there are forms of matter other than elements and compounds. Confounding examples from astronomy include white dwarfs, neutron…

Visits to science museums can provide a complement to the science learning carried out in schools. However, science museums are informal learning environments where teachers usually have very little control over the ideas being implicated or the experiments that the students carry out. It is necessary to design educational materials for the visit…

The purpose of this paper is to describe the development of both the instrumentation and the software of an emerging, high-technology system used for science instruction. A marriage of computer and television technologies has evolved into an exciting new learning system called interactive videodisc instruction. The development of the hardware…

Advantages and disadvantages of using multi-image or lap-dissolve (LD) slide techniques in large lecture sections are discussed. Production, use, and evaluation of LD programs are also discussed. Indicates that these programs are an effective way of improving instruction on visually oriented topics. (JN)

Discusses prototype interactive videodisc programs in chemistry designed to meet individual student needs. Also discusses three levels of program complexity for interactive videodisc instruction: search command (home consumer level); interaction built into program; and interaction resulting from use of an external computer as well as the videodisc…

Discusses problems professional teachers had in producing videotape materials for an organic chemistry course. Indicates that the tape program is a valuable addition to the organic lab course--its projected long lifetime compensating for the considerable task of its preparation. (Author/JN)
