A Study Of The Relative Importance Of Items Discussed In Parent-Teacher Conferences As Rated By Parents And Educators In The Logan City Schools, Robert W. Bickmore
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
There are numerous ways, both written and oral, in which the schools can report pupil progress to parents. Promising practices include parent-teacher conferences, notes to parents, combination of narrative reports and parent-teacher conferences, and progress check sheets indicating, among other things, attitudes and behavior.
Educators have long recognized the inadequacy of the report card and the traditional marking system. Studies show that no two teachers mark just alike, even with a common set of standards to follow. Children work for marks rather than self-improvement. Marks, alone, cannot and do not tell a complete story.
Elsbree (4) points out that many …

Courses For Managerial Training As Recommended By Managers Of Selected Utah Industries, B. Edward Lepper
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The United States is a growing nation; it is also an industrial nation. In the past century the spinning wheel has given way to the large clothing mills; a great network of miles and miles of electric power lines has replaced the kerosene lamp and provided power for work that was for years done by hand. Small horse-drawn earth moving equipment has given way to giant motor-driven bulldozers and transportation has progressed from the pony express and stagecoach to the huge trans-ocean airliners that make any spot on the globe only a matter of hours away. In like manner colleges …
Temperature Forecasting At Logan, Utah, For The Snowmelt-Runoff Season, Clifton Johnson
Temperature Forecasting At Logan, Utah, For The Snowmelt-Runoff Season, Clifton Johnson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this thesis is to investigate the practicability of forecasting temperatures for the spring and summer snowmelt-runoff season. A successful temperature forecast for Logan, Utah, would be useful in studies of Logan River streamflow, as well as other related applications.
Logan, Utah, is situated in a region where the snow accumulates during the winter and early spring at high altitudes and remains until the proper sequence of meteorological events provides the thermodynamic conditions essential for melting. Snow surveys provide an index to the water available on a watershed. Temperature conditions during the melt period largely determine the available …
A Comparison Of Academic Achievement Between Pupils Of Selected Small Elementary Schools And Large Elementary Schools In Box Elder County, Robert Morgan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Constitution of the United States brought a “new look” throughout the western world toward the position the American school was to play in the protection of the cherished and newly won freedoms. Congressional action, backed by majority public opinion, legally bound the responsible power of school maintenance and operation over to the state and local governments. It was believed that the first line of defense for the protection of democracy lay in the foundation of good schools, and their activities could be best augmented by the strong support of the family community life cooperatively working for the welfare of …
Thermodynamics Of Phosphate Absorption On Several Charcoals, James Duncan Beaton
Thermodynamics Of Phosphate Absorption On Several Charcoals, James Duncan Beaton
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Phosphorus has long been recognized by agriculturists as being one of the elements essential for plant growth. Although the total phosphorus content of a soil may be high, the amount of phosphate actually available for plant growth is often low. Many agencies such as inherent low solubilities of phosphate compounds, adsorption on Ca C03, adsorption in the diffuse double layer of clay micelles, and chemical precipitation of phosphate which refers to the removal of phosphate ions from solution and their chemical bonding to the solid phase have been studied to explain the lack of phosphate availability.

The Measurement Of Physical Properties Of Field Soil, Wilbur Sloat
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Since the beginning of soil tilled agriculture, there have been many controversies as to the proper kinds and amounts of soil tillage required to establish and produce a crop. These controversies have ranged far and wide between farmers, extension service personnel, agricultural specialists, in fact almost every person connected with agriculture has his own unique concept of what constitutes proper tillage. The concepts vary widely from a no tillage program, for certain perennial row crops, to the extreme dust mulch program.
The Alkali Tolerance Of Tall Wheatgrass, David L. Carter
The Alkali Tolerance Of Tall Wheatgrass, David L. Carter
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Alkali land occurs adjacent to nearly every extensively irrigated area. Much of this land is too alkaline to produce profitable crops. Each year thousands of acres or land are going out of production because or increasing alkalinity. This presents one or the most acute problem which confronts irrigation agriculture today.
Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen
Relationship Of Bicarbonate Concentration Of Plant Tissue To That Of The Growth Media As A Factor In Chlorosis, Gary H. Carlsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Throughout the years lime-induced chlorosis has contributed to untold economic losses. Although this disease has challenged the technical ingenuity of outstanding plant and soil scientists, the exact cause has never been determined; consequently, no preventative measures or permanent cures can, as yet, be recommended. This physiological malady, unchecked, continues its rampage in regions where the disease is prevalent.
The problem is of wide significance because calcareous soils are distributed throughout the world. It is of primary concern to us because the majority of the land of western United States is of this type. An estimated 500,000 acres of crops growing …
Cost And Efficiency In Producing Sugar Beets In Utah County, Utah, 1951, Randolph Lamar Larsen
Cost And Efficiency In Producing Sugar Beets In Utah County, Utah, 1951, Randolph Lamar Larsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Man has always included some form of sugar in his diet. Only in the past two centuries has sugar been developed as an individual food. During that time vast amounts of money and time have gone into the development and improvement of sugar. In 1747, a German chemist by the name of Andreas Marggraf proved that sugar beets contained sugar. One of his pupils, Franz Karl Achard, in 1799 gave further evidence of this fact by his experiments.
Breakfast Habits Of Some Utah School Children, Marlene M. Stegelmeier
Breakfast Habits Of Some Utah School Children, Marlene M. Stegelmeier
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
During the last 10 years, much emphasis has been placed on the importance of breakfast for people of all ages. Nutritionists have pointed out that persons who eat a hearty breakfast show fewer signs of mid-morning fatigue, have or develop better work habits, and do not get as hungry as those who eat little or no breakfast.
Many people do not realize the importance of starting the day with a good breakfast. The 12 to 13 hour fast which the body undergoes from the evening meal until breakfast time requires the consumption of an adequate breakfast. Many poor breakfasts may …
The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley
The Use Of Branchiostegal Rays To Determine Age Of Lake Trout Salvelinus Namaycush Walbaum, Ross Vivian Bulkley
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Any method used in aging fish must fulfill certain requirements to be satisfactory. If the method is inaccurate, naturally little reliance can be placed upon its use. If considerable study of the method and much practice are required before accurate readings can be obtained, the method will not come into widespread use. The requirements of an aging method, then are that it must be accurate and comparatively easy. The scale method for aging lake trout (Salvelinus namaycush Walbaum) unfortunately does not fulfill these requirements. It has always been difficult to tell the age of lake trout by the examination …

The increasing importance of the airplane in present day civilization
Throughout the ages, after each development in speed of communications and transportation, man has made noteworthy changes in his way of living. Indications are that the gradual development of the airplane to a safe and rapid means of transportation has had a great effect upon society by pushing back the frontiers of the world both geographically and scientifically. The impact of this speed has influenced almost every home and certainly every school in America.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The prospective student who has been accepted and who fails to arrive on the college campus despite his apparent intentions presents a problem to secondary school principals as well as to college officials. Non-arrivals are common on the admissions records of every college or university. (14) Alden B. Threasher reports admissions attrition percentages ranged from 3 percent to 55 percent with averages of 27 percent to 46 percent in a study of 58 institutions grouped by type.

An Evaluation Of The Social Dance Program At The Box Elder Junior Division, Howard Dale Rasmussen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Social dancing has for many years occupied a position of prominence in the physical education curriculum at the Box Elder Junior Division. It has maintained this position because of the recognized necessity to help students of the junior high age overcome a social barrier which is quite pronounced.
Irwin suggests:
It is now generally accepted that the social development of pupils is an important part of general education. Desirable social relationships are extremely important in all phases of school life as well as in adult life . . . Social dancing should be stressed for boys and girls because of …
Ecology Of Plant Distribution On The Salt-Deserts Of Utah, Dillard H. Gates
Ecology Of Plant Distribution On The Salt-Deserts Of Utah, Dillard H. Gates
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The reciprocal effects of vegetation and soils have long been a subject of speculation and conjecture. In the management of any natural land area the problem of interpreting vegetational expression is especially important. The effects of native vegetation on soils and the effects of the soil on the vegetation have been studied and observed for many years. The arid-desert range lands have been studied least and as a result are not well understood.
As human populations increase there will be additional need for agricultural production, and these lands may be put to higher use, perhaps even to irrigated crop production. …
A Comparison Of Fluid Milk Processing 6 And 3 Days Per Week In One Small Plant, Utah 1953, John L. Willis
A Comparison Of Fluid Milk Processing 6 And 3 Days Per Week In One Small Plant, Utah 1953, John L. Willis
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Many of the fluid milk processing plants in Utah are relatively small. The typical small plant in Utah is generally family operated with some hired help. Although most of the small plants are individually owned, some are operated as partnerships. Often the same man picks-up, processes, and then delivers the milk. Some of the processors also own dairy herds. In these cases the same man performs all the functions necessary to carry the milk products from the farm to the consumer's door. It is not uncommon to find the plant owner and manager performing all these duties himself.

A Study Of The Problems Of Teaching Health In Selected High Schools Of Utah, Frank R. Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
It was the general belief of the developers, curators and protectors of the American form of Government that education of the masses is the backbone of the Democratic way of life practiced in the United States. This belief has been the foundation for the development of broad curriculums, expanded facilities and increased enrollment in teacher training institutions; especially since the beginning of World War II. The teacher shortage so prevalent in the United States at present has aroused the public and educators alike to concern about the welfare of the teacher, and the schooling of the child.
Differences In Frustration Reactions Of A Group Of Preschool Children, Lorraine Storey
Differences In Frustration Reactions Of A Group Of Preschool Children, Lorraine Storey
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In recent years, the concept of frustration has been central in both mental hygiene and social psychology. This is rightfully so. Frustration has been defined as any kind of thwarting or blocking of the motive (4, 7, 14). Any person involved in modern day living is confronted with many types of situations which do actually block or thwart his wishes or drives. A person may be blocked because of conditions existing in the environment, because of personal inadequacies, and because of conflicting drives. Since a person is forced to face so many sources of frustration, the method that he chooses …
The Economics Of Turkey Production In Utah, 1954, Richard W. Kearl
The Economics Of Turkey Production In Utah, 1954, Richard W. Kearl
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The production of turkeys by farmers for market in Utah has risen from a meager beginning a few decades ago, to one of the important agricultural industries today. Utah's turkey industry has expanded tenfold from the 226,000 head sold in 1929 to the record high 2,285,000 head sold in 1954. Pounds sold was 13 times greater in 1954 than in 1929 due to the increased weight per bird as well as to the increase in number of head. The record number of 2,285,000 head sold for the amount of $10,635,000. This accounted for about seven per cent of the total …

A Follow-Up Study Of Utah State Agricultural College Graduates In 1948, 1951, And 1954, Who Obtained Secondary Teaching Certificates, Wendell Blair Low
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Many educators consider the shortage of qualified teaching personnel as one of the most serious problems in education. In the past this shortage has been primarily confined to the elementary level. However, the United States Department of Education states:
Long-run forecasts of population indicate that employment of secondary teachers should be higher throughout the forty-year period 1960-2000 than in 1950. The long-range trend for a rising proportion of young people to attend high school is expected to continue. Greatly increased Federal and State aid to education might expand enrollments considerably. The trend toward enriching curriculum, offering special subjects, and extending …
The Effect Of Bicarbonate On The Uptake Of Zinc By Plants, Lawrence G. Morrill
The Effect Of Bicarbonate On The Uptake Of Zinc By Plants, Lawrence G. Morrill
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Zinc deficiencies occur in many fruit orchards in Utah even though the soil contains amounts of zinc that would normally be sufficient for good plant growth. The existing zinc problem in Utah is, therefore, one of availability.
Problems of zinc availability generally occur in the pH range of 6-8. Zinc deficiencies occurring within this pH range are more frequently found on well-aerated soils than on poorly aerated ones with other conditions being the same. It has been shown that carbon dioxide will convert both zinc hydroxide and zinc carbonate into more soluble bicarbonates with the concentration of Zn++ that …
Land Fragmentation And Water Utilization In Relation To Their Social Milieu, Paragonah, Utah, Robert G. Painter
Land Fragmentation And Water Utilization In Relation To Their Social Milieu, Paragonah, Utah, Robert G. Painter
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Practices of land use in Utah show need for community action aimed at more adequate utilization of land and water resources. Use of land for crop production in Utah is limited by topography, soil type, elevation, climate, and moisture (26, p.3). Because of limitations imposed, only a small portion of the land area may be used for cultivated farming. As a rule, large land holdings in Utah are not regularly tilled but are used as range for raising livestock.
Farm cropland may be separated into two general classes: irrigated and dry-land. In general, the cropland of most farms is entirely …
Growth And Nutrition Of Plants As Affected By Different Osmotic Concentrations Of Calcium Chloride And Sodium Chloride In The Substrate, Mumtaz Ali Khan
Growth And Nutrition Of Plants As Affected By Different Osmotic Concentrations Of Calcium Chloride And Sodium Chloride In The Substrate, Mumtaz Ali Khan
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Considerable experimental evidence supports the concept that the growth of plants generally decreases progressively as the salt concentration of the substrate increases, but certain relationships between plant and substrate are still not fully understood. The chemistry of salt toxicity to plants involves many interactions both as to the quantity and kind of ions presented to the roots and those accumulated in the plants. Many plant species have shown sensitivity to excess accumulation of specific salts frequently encountered in saline soils. Thus Eaton (1942), Wadleigh, Hayward, and Ayers (1951) have shown most of the fruit trees to be susceptible to injury …
The Thermodynamics And Some Practical Aspects Of Zinc Adsorption On Calcite, Dolomite, And Calcian-Magnesite Minerals, Jerome J. Jurinak
The Thermodynamics And Some Practical Aspects Of Zinc Adsorption On Calcite, Dolomite, And Calcian-Magnesite Minerals, Jerome J. Jurinak
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Zinc is one of the essential elements required for the normal growth of plants. The total amount of zinc commonly occurring in soils is usually many times greater than that necessary to supply the needs of actively growing plants. The ability of the soil to "fix" zinc in form unavailable for plant use, however, has made the zinc deficiency disease an important plant nutrition problem in the major fruit and nut growing regions of the West. Fixation mechanisms which have been postulated as contributing to zinc deficiency include organic complexes, precipitation of insoluble inorganic salts, and strong zinc-clay intersections. It …

On The Kinetics Of Moisture Flow In Unsaturated Soils, James Wellington Biggar
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The flow of fluids in porous media continues to be a widely studied phenomenon. Soil moisture relationships and particularly the flow of water in soil is perhaps the most widely investigated of the four edaphatic factors related to plant growth, namely moisture, aeration, temperature and compaction.
