Although the schools had different philosophies and objectives, many of the newly developed alternatives had a common bond-they believed that students learn in numerous ways at different stages of their lives, and some students learn better in different environments, whether open, formal, informal, competitive, or non-competitive (Case, 1981). Many scholars in education contend that the present thrust of alternative education can be traced to the civil rights movement of the 1960s (Fantini, 1973; Deal and Nolan, 1978). They believe that desegregation gained momentum because parents and community leaders boycotted public schools and collaborated to continue the education of children in Freedom Schools. The purpose of these schools was to provide an educational experience for students that would make it possible for them to challenge the realities of learning and the myths of our society (Wolf et al., 1974). For many blacks and whites alike, the Freedom Schools, as they were called, provided a glimpse of alternative programs tailored to students' needs. They included curriculum geared specifically to the selfdetermined concerns of students and sympathetic adults working with children (Barr et al., 1977). To ensure that educational concerns were not overlooked, teachers established a flexible procedure that expanded the boundaries of schooling to include the community and its resources. Smaller educational units were created to humanize the experience (Case, 1981). These ingredients are still present in the current alternative school movement. The continued growth of alternative schools was 8 further stimulated by the growing critique of education and the increased pressures on schools to better serve each student. Declining test scores, coupled with a decline in public confidence in schools, increased the pressure on schools to do better jobs. Many educators saw the alternative education movement as a means of tailoring educational program content, approach, structure, and climate to the specific needs of different groups. Another social trend that contributed to the alternative school was the counter culture movement. The participants in this movement saw public schools as dehumanizing, cold, and irrelevant institutions. Many thought that educational institutions were authorative, reflecting bad values of a rich, dominating society (Raywid, 1981). The backing of John Dewey also contributed to the primary concept that led to alternative education-"learn by doing." This concept gave to the learner more freedom to maximize his/her talents. Other scholars (Graubard, 1973; Dennison, 1969) all supported the concept of individual freedom, believing that if a child is innately curious and realistic and left to himself/herself, that child will develop as far as he/she is capable of developing. Bloom also emphasized his beliefs on learning styles. He believed that each child can achieve, if given the time to master learning skills (Bloom, 1976). In other words, educators must realize that different students learn at differe...
Objective: Determine the effect of drinker number (1, 2, or 3 drinkers/pen) on the frequency and duration for drinker visits, aggressive interactions in the drinker vicinity, drinker location preference, and water disappearance for 7-week-old nursery pigs. Materials and methods: Two hundred twenty-five, 7-week-old gilts identified with unique numbers were commercially housed (25 gilts/pen). Three treatments were compared with 3 pens/treatment: 1 drinker (treatment 1), 2 drinkers (treatment 2), and 3 drinkers (treatment 3). One camera was positioned over each drinker to record behavior between 7:00 am and 12:59 pm over 2 consecutive days. In addition, 1 water meter was installed on each water line to record water disappearance. Results: Pigs in treatment 3 visited and spent more time at the drinkers compared to the other 2 treatments (P = .02). Pigs in treatment 1 had more and longer duration of aggressive interactions in the drinker vicinity compared to the other 2 treatments between 7:00 am to 7:59 am (P = .02). When offered 3 drinkers, pigs spent the least amount of time at the drinker across from the feeder near the alleyway (P < .001). Total water disappearance was greatest for treatment 1 and least for treatment 2. Implications: Under study conditions, 3 drinkers increased visits and time at drinkers without increasing aggressive interactions. Pigs exhibited location preference when offered 3 drinkers. Results can inform producers on water placement in pens.
The objective of this study was to determine the effects on pig behavior, performance and physiology of removing sub-therapeutic antibiotics from diets provided to nursery pigs. Including additional fat instead of the traditional antibiotics made the feed more palatable therefore; the treatment group (without antibiotic rations) visited the feeder more quickly and had an improved Feed-to-Gain ratio (F: G) than the control (pigs provided antibiotics) pigs. This study determined that when using high health status pigs, sub-therapeutic antibiotics may be omitted from the diets.
