Gary C. Bates reviewed 82 studies and concluded that " A number of possible explanations exist for this discouraging conclusion. Much of the research comes from doctoral studies which are usually first attempts at research. Very few studies include a follow-up of the subjects involved to see if there were ant changes other than those tested for at the end of the study.
Often these instructional approaches are not described in sufficient detail for the reader to be able to judge the value of the study. As McKeachie pointed out, laboratory teaching may not be the best method to choose if one's objective is to have students retain information.
However, the need for "educational accountability" has been translated into the need to increase test scores. Some of the outcomes of a "lab approach" are difficult to test in a multiple-choice test.
Positive research findings on the role of the laboratory in science teaching do exist. Laboratory activities appear to be helpful for students rated as medium to low in achievement on pretest measures Boghai, ; Grozier, Godomsky reported that laboratory instruction increased students' problem-solving ability in physical chemistry and that the laboratory could be a valuable instructional technique in chemistry if experiments were genuine problems without explicit directions.
Working with older, disadvantaged students in a laboratory setting, researchers McKinnon, ; McDermott et al. No space has been allocated in this discussion of the role of the laboratory to the approach involved: inquiry vs. It has been assumed that proponents of laboratory activities are interested in having students inquire and in having them work with concrete objects.
Comber and Keeves found, when studying science education in 19 countries, that in six countries where year-old students made observations and did experiments in their schools, the level of achievement in science was higher than in schools where students did not perform these activities. A modern research technique is meta-analysis - in which a group of studies is analyzed for similarities and differences in findings related to their common thrust. A meta-analysis on the effects of various instructional techniques Wise and Okey, was focused on 12 teaching strategies.
Two of these 12 were related to the laboratory approach: inquiry-discovery and manipulative. Although these two strategies did not exhibit as large an effect as did the strategies of focusing and questioning, there was some positive support for inquiry teaching. An effective science classroom was characterized as one in which students had opportunities to physically interact with instructional materials and engage in varied kinds of activities , p.
Lott reported on a meta-analysis of the effect of inquiry inductive teaching and advance organizers in science education. Lott wrote that the inductive approach appeared to be more useful than the deductive in those situations where high levels of thought, learning experiences, and outcomes demands were placed upon subjects , p. Science educators at all levels need to continue to study the role of the laboratory in science teaching.
However, perhaps the question we should be asking is not "What is the laboratory better than? Blosser, Patricia E. Boghai, Davar M. No foods inside the labs. The science labs are very risky therefore take these things very seriously before step up to the labs. In the span of modern generation, we are completely depends on the Computer and Internet.
We are almost blind and buried without the use of computer. It is one of the most important equipment that help us almost in every field. Therefore, the knowledge of computer is very necessary for the students bright future and career. The knowledge of computer will also give them advanced career opportunity in the future.
Like Science Labs, the computer labs has also safety measurement. The students must follow the safety and guidelines given by the faculties and lab assistant of schools. Do not touch on any electronics wire that attached to computer, In case of any troubleshoot contact teacher or lab assistant, do not try to repair or install anythings in the computer, no foods inside the labs.
Hence, we understand how modern laboratory is important for the education system and also understand its valuation. It is the responsibilities of the students to well- maintained the laboratories and keep it safe. Also, the teachers must guide the students in each and every experiments.
