Discusses materials needed, procedures used, and typical results obtained for experiments designed to make a numerical stepwise study of the oxygenation of hemoglobin, myoglobin, and other oxygen carriers. (JN)

Provides basic information on the anatomy, physiology, behaviors, and distribution patterns of the box turtle. Offers suggestions for the turtle's care and maintenance in a classroom environment. (ML)

Background information, procedures used, and typical results obtained are provided for an experiment in which students prepare and study the characteristics of a "slime." A list of general, inorganic, and polymer chemistry concepts fostered in the experiment is included. (JN)

Discusses materials needed, procedures used, and typical results obtained for an experiment involving a dry attack of ores with pyrosulfate flux. The experiment has been carried out by about 150 students a year with a demonstrator-to-student ratio of about 1:15 with no serious accidents. (JN)

Books that may help children appreciate and understand feats that can be performed because of scientific and technological discoveries are discussed. (DF)

To demonstrate negative feedback a power amplifier is constructed from an operational amplifier together with a complementary pair of transistors as an output stage. The amplifier is developed and tested stage by stage, and at each stage the defects apparent at the previous stage are eliminated. (JN)

Presents evidence which, on one hand, disconfirms storage interpretations of the constituent boundary effect and, on the other hand, supports a specific retrieval interpretation. (Author)

Presents a more precise analysis of the way in which semantic constraints affect the perception of reversible sentences. (Author/RK)

This paper presents results from a preliminary investigation in which researchers manipulated the cover story of an open-ended assessment that required students to design an experiment. Participants were 27 sixth graders from a culturally diverse urban school. In one version of the cover story, students were asked to design an experiment to test a…

A Classroom teaching method for elementary schools utilizes the physical stimuli of spatial outlays (stations) in conjunction with organized discovery.'' Stations for math, art, and social science are described. (JB)

The present study contrasted the robustness of the WSD and the F test to heterogeneity of variances. (Author)

The author discusses ways of revising presientific ideas among children, using the topic "Changes in Aggregate States of Matter" as a source for specific examples. (JH)

Purpose of research was to examine the contribution that expectancy to teach could make as a possible incentive for meaningful verbal (school) learning. (Author)

Examines the relationship between illusory changes of repeated words (verbal transformations) and illusory presence of phonemes replaced by noise (phonemic restorations); paper presented at the 82nd meeting of the Acoustical Society of America, Denver, Colorado, October 1971, and supported in part by a University of Wisconsin-Milwaukee Graduate…
