This study aims to explore the literature on learning interventions that can enhance students' multiple representation skills and identify indicators for assessing multiple representation abilities in physics education. Following the PRISMA procedure, the research is a systematic literature review using qualitative content analysis techniques. The…

Single-type, 8-fold-grooved, commercially accessible interlocking disks (ILDs) have been used for modeling of complex polyhedral and reticular topologies with relevance to inorganic and hybrid materials. The assembly of complex topologies relies on the preparation of secondary building units (SBUs), which exhibit different connectivity than that…

The purpose of this study is to develop an instructional materials using discovery learning with cognitive conflict approach to improve vocational students understanding of heat concept. This instructional material was developed using the Four D model, namely define, design, develop, and disseminate. Furthermore, data were obtained from the…

Presents a method to convince students that the image produced by a plane mirror is actually behind the mirror. Uses observations that the letters of an eye chart posted on a mirror are twice the size of the images of letters of an eye chart they are holding. Provides two reproducible eye charts. (MDH)

Designed for quick, easy identification of some of the most commonly encountered organisms found in and around the school ground, this illustrated guide identifies by a picture and a short biological description the common animals and plants found in and around school lawns, house lawns, parks, fence rows, flower gardens, vacant lots, and…

Presents some introductory experiments involving the reaction between EDTA and several metal ions using metallochromic indicators. The experiments represent familiar reactions and are followed by suggestions for extension into areas of discovery work by students. (Author/SA)

Describes the federal legislation introduced in 1991 that provides formula grants to states to purchase elementary science equipment. The purchases are to be matched by local education agencies and coordinated with hands-on laboratory activities. (MDH)

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…

This second volume in the Topics for Teachers series provides a wide range of activities designed to be both useful for teachers and informative for students. The investigations contained in this document are representative of some of the embodiments of important mathematical principles in the physical world. The activities included were chosen…

A program is described in which parent volunteers assist in science instruction at the kindergarten/first grade level. Examples of activities within the mini-units are given. (SA)

This guide contains experiments in the fields of Physical Science, Earth Science, and Biological Science designed to be used with any series of texts in a sequence for disadvantaged youth in the middle school. Any standard classroom can be used, with minor modifications and inexpensive equipment and materials. All students could participate,…

Insights gained from experience and research on language minority students' academic success are reviewed as background for presentation of a curriculum that is bilingual and content-based and uses cooperative learning techniques. First, findings on three elements of success (interest and motivation, intelligence and development, and psychosocial…
