The Fowler Diet Cola Test (DCT) was originally developed to assess the scientific process skills of students in science classrooms. The use of the test is generally suggested for gifted students in science. There are considerable number of Scientific Process Skills (SPS) tests that the researchers developed for different student population. The…

The results of an earlier four-year longitudinal research study on the development of experimental design skills led to the conclusion that 12-13 year old students probably need more help to design experiments than had been offered to them in that project. This paper reports the findings of the first year of a further four-year empirical research…

Indonesia and many other developing countries have a vast youth population, yet limited facilities for physics learning. The major purposes of this study are to develop low-cost, technology-enhanced physical and virtual laboratories and to investigate their effects on various learning objectives, including conceptual understanding, inquiry…

The dramatic decrease in the cost of sequencing a human genome is leading to an era in which a wide range of students will benefit from having an understanding of human genetic variation. Since over 90% of sequence variation between humans is in the form of single nucleotide polymorphisms (SNPs), a laboratory exercise has been devised in order to…

Physical and virtual experimentation are thought to have different affordances for supporting students' learning. Research investigating the use of physical and virtual experiments to support students' learning has identified a variety of, sometimes conflicting, outcomes. Unanswered questions remain about how physical and virtual experiments may…

The plasma state is included in the unit on matter and its properties in the 9th grade Physics course secondary school curriculum prepared by the Ministry of National Education of Turkey. Any tools and equipment required by tests to be conducted in the scope of the Physics course curriculum are in general easily accessible. However, in cases in…

The educational objectives related to the plasma state of matter, which comprises more than 90% of our universe, are located in the "properties of substances" unit in the 9th grade high school physics course curriculum. If there are physical and technical limitations while performing an experiment, the use of different techniques is…

Terms to be familiar with before you start to solve the test: cell cycle, generation time, S-phase, cell culture synchronization, isotopic pulse-chase labeling, density labeling, equilibrium density-gradient centrifugation, buoyant density, rate-zonal centrifugation, nucleoside, nucleotide, kinase enzymes, polymerization of nucleic acids,…

This paper shows the results of an experiment in which the effects of fibroblast growth factor (FGF), actinomycin D (Act D; an inhibitor of transcription), and cycloheximide (CHX; an inhibitor of translation) were studied on the expression of two genes: a gene called "Fnk" and the gene coding for glyceraldehyde-3-phosphate dehydrogenase (GAPDH).…

In traditional teaching, the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time solving problems in a more or less rote manner. However, physics education research has shown that the fundamental concepts of the electromagnetic induction theory are barely understood by students. This article…

This is the start of a road map for the effective introduction of inquiry-based learning in chemistry. Advantages of inquiry-based approaches to the development of scientific literacy are widely discussed in the literature. However, unless chemistry educators take account of teachers' reservations and identified disadvantages such approaches will…

This document was developed to provide eighth-grade teachers in New York City with a sequence of instructional activities in science. The major portion of the guide is divided into four instructional units. The first unit, "Chemistry," includes lessons and activities on liquid solutions, suspensions and emulsions, acids, bases,…

Contains five articles about various aspects of British science education. Includes articles on norm referenced versus criterion referenced assessment, proportionality in science education, practical skills in advanced level chemistry, creating an antiracist ethos, and heat transfer experiments.
