Chemistry Teachers’ Misconceptions Concerning Concept of Chemical Reaction Rate

Common Misconceptions Concerning Heuristic Search

This paper examines the following statements about heuristic search, which are commonly held to be true: More accurate heuristics result in fewer states being expanded by A* and IDA*. A* expands fewer states than any other equally informed algorithm that finds optimal solutions. Any admissible heuristic can be turned into a consistent heuristic by a simple technique called . In search spaces wh...

Chemical reaction rate and diffusion rate

Chemical reaction rate and diffusion rate were defined. The concomitant advances in theory, measuring systems and computer simulation bring the new perspectives to the chemical reaction with diffusion studying. The obtained results shows effect the chemical reaction rate and diffusion. The obtained results demonstrate characterization of the dynamic and steady state conditions of the chemical s...

Persistent Misconceptions concerning Null Hypothesis Significance Testing

ABTRACT The Null Hypothesis Significance Test is a popular testing procedure used mainly in the social sciences and occasionally in the natural sciences. The procedure has been criticized on several grounds. Firstly, opponents have attacked the procedure itself, claiming that it either does not tell the researcher what he or she wants to know; and/or that the procedure is not logically valid. S...

Using Concept Maps to Assess and Categorize Elementary Preservice Teachers Misconceptions

This research study reports on the use of concept maps as an assessment tool to investigate elementary pre-service teacher knowledge about dissolving. Propositions from pre/post concept maps were scored using the total proposition accuracy scoring technique (TPA) and were also used to classify concepts as scientific or spontaneous using Vygotsky’s theory of concept development. Vygotsky (1986) ...
