The Organization Of An Academy, Joseph C, Gilman Jan 1940

The Organization Of An Academy, Joseph C, Gilman

Proceedings of the Iowa Academy of Science

The Academy Conference of the American Association for the Advancement of Science is the one place in which representatives of the state academies meet for discussion of their common interests and problems. Since in the past ten years other immediate needs have held its attention, no discussion of the ever present problem of the methods of attaining its objectives has been presented, hence the present subject: - the organization of an academy-was chosen for discussion. As qualifications for presenting this material, the experiences during the past ten years as secretary of the Iowa Academy of Science and also the representative …


The Address Of The President: Science And Progress, R. B. Mcclenon Jan 1940

The Address Of The President: Science And Progress, R. B. Mcclenon

Proceedings of the Iowa Academy of Science

Science and human welfare have always risen and fallen together. We find this generalization borne out in all recorded history, and even farther back in the dim horizons of prehistory. From the first attempts at counting and measuring, observation of the precision of the periodic recurrence of the seasons, forging of metal tools and weapons, domestication of animals, planting and harvesting of crops, we see that the slow advance of the status of man in his world has been accompanied or even preceded by the advance in science. In the earlier stages, of course, we find art, culture, and the …


College Student Behavior As An Evaluation Of The Iowa Home Adjustment Inventory, Earle E. Emme, Irvine Thoe Jan 1940

College Student Behavior As An Evaluation Of The Iowa Home Adjustment Inventory, Earle E. Emme, Irvine Thoe

Proceedings of the Iowa Academy of Science

One hundred forty freshman students, 56 women and 84 men, were given the Iowa Home Adjustment Inventory. Confidential information was then obtained on thirty out-of-town students. Raters reported on only those whose student behavior was specifically known to them. Ten freshman women live in the Women's Dormitory. There is no men's dormitory, and all the men live either at their own homes or in private homes. This made the desired information not as easily obtainable as on a campus where more students live in dormitories. Furthermore, the conduct of the student who is living at home does not so easily …


A New Test Of Imagination, Martin F. Fritz Jan 1940

A New Test Of Imagination, Martin F. Fritz

Proceedings of the Iowa Academy of Science

A cube drawn in perspective on paper is placed before the subject. The test consists in following one of the eight corners as the cube is tumbled about, in imagination; tipped forward or backward, to the right or left, or turned half way around. These movements makes possible a series of problems graded in difficulty. This test was given to freshman students at Iowa State College in 1933. The mean number of problems correctly solved by Agriculture, Home Economics, and Engineering students was 6.45 ± 0.21, 4.93 ± 0.15, and 9.04 ± 0.20, respectively. The critical ratios were Agri.-Home Ec., …

An Apparatus For Measuring Tolerance To Light And Visual Efficiency Under Different Conditions Of Illumination, Glenn O. Martinson Jan 1940

An Apparatus For Measuring Tolerance To Light And Visual Efficiency Under Different Conditions Of Illumination, Glenn O. Martinson

Proceedings of the Iowa Academy of Science

Illumination in relation to automobile driving is considered one of the most important problems of highway safety. Because of contrast between source of light and background, lights which give sufficient illumination are considered blinding. An apparatus is described which makes possible the accurate measurement of tolerance to light under different atmospheric conditions. Calibration of the light falling on the test object and the light impinging on the retina makes possible measurement of the optimal conditions of illumination under different degrees of darkness. The light measurements are made by electrometric methods.


A Study Of Progress In Reading At Grade Five Level, Maxwell F. Smith Jan 1940

A Study Of Progress In Reading At Grade Five Level, Maxwell F. Smith

Proceedings of the Iowa Academy of Science

Reading tests were given to a ten-year-old fifth grade girl for a period of six weeks. Two types of material were used: (1) material from a text book of the fifth grade level was used in daily tests; (2) tests were given two days each week from material used at the college level. Instructions as to the proper reading technique were an integral part of the administration of the daily practices and checks on the fifth grade material. The exercises with college grade material were preceded by discussion and clarification of vocabulary. The subject progressed, in the daily tests, from …


Driving Aptitude Of Ccc Enrollees As Compared With A Similar Age Group From The General Population, Theron S. Carty, A. R. Lauer Jan 1940

Driving Aptitude Of Ccc Enrollees As Compared With A Similar Age Group From The General Population, Theron S. Carty, A. R. Lauer

Proceedings of the Iowa Academy of Science

Two groups of individuals were compared on characteristics pertaining to sensory, motor and central processes, assumed to be necessary to efficiency in driving an automobile, to determine the degree of similarity between traits of 44 CCC enrollees and an unselected sample of 70 youths from the same age groups. The only significant differences found were: (1) CCC enrollees were shorter in stature and (2) less active than the .general population. (3) The vision of the CCC enrollees was also poorer and (4) they lacked experience with automobiles as compared with the average youth.

A Study Of The Development Of Skill In Learning To Operate The Hollerith Card-Punching Machine, W. Leroy Cation Jan 1939

A Study Of The Development Of Skill In Learning To Operate The Hollerith Card-Punching Machine, W. Leroy Cation

Proceedings of the Iowa Academy of Science

In this study the writer served as both subject and experimenter. Previous to this experiment the writer had had 110 experience in punching Hollerith cards. The data used for punching were coded prior to the actual punching- of the cards. The 80-column card was used. There were sixteen 30-minute periods throughout a period of five weeks. With two unavoidable exceptions the practice periods were held each Monday, Wednesday, and Friday at 4:00 P.M.


A Reversible Card-Sorting Board, Martin F. Fritz Jan 1939

A Reversible Card-Sorting Board, Martin F. Fritz

Proceedings of the Iowa Academy of Science

In the study of antagonistic visual habits (Fritz, J. Comparative Psycho!., 1930, 11, 171-184), it is necessary to devise a method whereby certain selected habits directly oppose each other. Each learned act must have a counterpart in an antagonistic act so as to produce .interference. Such a system of mutually exclusive habits can be arranged by means of the card sorting technique. Fifty playing cards are glued to a board in a pattern so that when the board is turned around (180 degrees), the numbers (pips) will be the same but the suits reversed, that is, black and red suits …


The Comparison And Correlation Of Certain Attitudes And Deceptive Tendencies, Wayne Leffler Jan 1939

The Comparison And Correlation Of Certain Attitudes And Deceptive Tendencies, Wayne Leffler

Proceedings of the Iowa Academy of Science

Various studies made by Voelker and Howells have indicated specific tendencies to cheat in persons. Martson found that women were 14 times as honest and 9 times as truthful as men on the average. An unpublished study by Johns and Lauer, made of 94 delinquent boys, indicated a tendency to cheat in certain subject matter. The examinees tended to overstate their knowledge of music and parts of automobiles, but gave a more or less correct statement of knowledge concerning books of the Bible. The present study is an attempt to secure data on comparison of tendency of students to cheat …


The Effect Of Distraction On The Frequency Of Stuttering, Virginia Barber Jan 1939

The Effect Of Distraction On The Frequency Of Stuttering, Virginia Barber

Proceedings of the Iowa Academy of Science

It is well known that under certain "distraction" situations stutterers are able to read with greatly increased fluency or even with complete freedom from stuttering. Two investigations of the effect of distraction were made: (1) of chorus reading, and (2) of various rhythms.


Practice In Skills Designed To Improve Ability In Playing Handball, H. C. Bennion Jan 1939

Practice In Skills Designed To Improve Ability In Playing Handball, H. C. Bennion

Proceedings of the Iowa Academy of Science

Practice sessions in the skill described in this paper were carried on by the writer during the months of January and February, 1939. The object of the practice sessions was to develop skill in handball, in which the subject had had no previous experience. Before deciding on the method of procedure, the subject observed several expert players. He then decided to practice along three lines which seemed most important in securing proficiency in the game.

An Experiment In Transfer Of Training, Ruth B. Mcdonald Jan 1939

An Experiment In Transfer Of Training, Ruth B. Mcdonald

Proceedings of the Iowa Academy of Science

Much work has been done on the transfer of training in experiments of perception and motor skills, and some studies have been made using school subject matter. The idea of formal discipline upon which some of the work in the schools has been based, has given way to the more modern phenomenon of transfer. Many of the studies carried on demonstrated transfer effects averaging from 20 to 30 per cent. The present study has to do with the simple sensori-motor skill of card sorting. It was assumed at the beginning of the experiment that negative transfer would be noted. The …

Methods In Teaching Ornithology, T. C. Stephens Jan 1939

Methods In Teaching Ornithology, T. C. Stephens

Proceedings of the Iowa Academy of Science

A brief outline is here presented of a course in ornithology (bird study, if you prefer) as I have tried to give it - never with complete success, however. In the first place, I have planned a course to give the student four semester hours of credit. (As a matter of fact, the undergraduate student of this day has so many "requirements" to satisfy, for graduation, for major and minor, for a teaching certificate, for practice teaching, or in his pre-professional schedule, that most students have difficulty in finding time for a 4-hour elective course). In many respects the second …


Iowa's Contribution To American Men Of Science, H. E. Zabel Jan 1939

Iowa's Contribution To American Men Of Science, H. E. Zabel

Proceedings of the Iowa Academy of Science

The latest edition of the Biographical Directory of Scientists lists 2623 who are now in Iowa or were formerly here. For every twenty-one of the present North American scientists, two are or were Iowans. Of these Iowans, 1110 were born in Iowa. Only six states have a larger number of native scientists. Of the outstanding or "starred" scientists, fifty-nine are native Iowans, a number exceeded by only five states. There is a native Iowa scientist for every 2275 of Iowa's present population, a ratio exceeded only by two states, each with a much smaller population, namely, Vermont and Utah.

A Comparison Of Four Methods Of Increasing The Reading Speed Of College Students, Lyle K. Henry, A. R. Lauer Jan 1939

A Comparison Of Four Methods Of Increasing The Reading Speed Of College Students, Lyle K. Henry, A. R. Lauer

Proceedings of the Iowa Academy of Science

Research in the field of education has brought out many weaknesses of the older systems and methods of presenting subject matter. Perhaps some of the most revealing studies have been in the field of reading. The early work of Dodge (1) has been adequately supplemented by the researches of Gates (2) Judd (4) Gray and others. Not only have vast individual differences in reading rate been noted, but marked improvement has also been effected by systematic practice exercises. Much of the earlier work was done with grade pupils in the regular courses of study in reading. More recently Pressey (6) …


Frequency Of Serious Visual Defects, Edith Burma, A. R. Lauer Jan 1939

Frequency Of Serious Visual Defects, Edith Burma, A. R. Lauer

Proceedings of the Iowa Academy of Science

Many practitioners have thousands of cards in their patient files which might be used to determine the visual conditions of clinical patients when they appear for examination. From the standpoint of the motor vehicle administrator, two other problems exist. One treats of what the practitioner would find if he were to examine a random sampling of the population to ascertain the extent of visual defects, using regular clinical methods. The other deals with the percentage of defects which a trained examiner giving regular driver’s license examinations might find in a non-clinical population. By non-clinical we mean a sampling of the …
