Compare And Contrast

Laboratory experience and skills are not only essential for success in science studies, but are the most exciting and rewarding aspects of science for students. As a result, many biology teachers have become critical of the efficacy of cookbook-type laboratory activities as well as the purposes, practices, and learning outcomes of lab experiments conducted in this regimented way. In our proposed lab approach, instead of asking students to compare and contrast living cells from various kingdoms, we ask that students design and conduct lab experiments to obtain the empirical evidence to disprove both Schleiden’s and Schwann’s generalizations that all living things, including plants and animals, are composed of identical units called “cells.” Students must then write up their findings in a paper intended for publication in a peer-reviewed scientific journal. Through this process, students learn the scientific method; concepts such as testability, falsifiability, and repeatability; and the requirements of communicating scientific findings through peer-reviewed publication.

Learning is essentially a process of interaction with all situations around individuals. Learning can be viewed as a process directed to the goals and processes of doing through various experiences. Learning is also a process of seeing, observing, and understanding things. In the learning process there are two activities that interact, namely learning activities and teaching activities.Learning is an active activity of learners in building meaning or understanding. Activity learners in undergoing learning activities is one key to success to improve learning outcomes. Optimal learning outcomes are the main goals to be achieved in the learning process. To optimize the learning outcomes of learners required methods and learning models in accordance with teaching materials. The learning process can be done in school, at home, or in the place of study guidance. For learning in school, learners are exposed to a number of subjects, one of them is biology subjects. Biology is one of the subjects received by students in high school. Biology is the study of the structure contained in living things. More simply can be said that biology is closely related to daily life. What we experience, what we do, why it happened and why. Subjects in the subject of biology are generally theoretical, but also the ability of learners to understand the concept to link learning with daily life. One of the biology subject matter in the form of conceptual or theoretical understanding is tissue in plants.

This article gives the analysis of five curriculums on Botany for the last ten years that have been carried out at Kremenets Regional Humanitarian Pedagogical Academy named after Taras Shevchenko (2008 – “Botany”, 2012 – “Anatomy and Plant Morphology”, “Plant Systematics” and “Mycology”, 2016 – “Botany”). The comparison of such structural elements of the curriculum as the content, the number of lecture and laboratory work hours, the number of independent and individual work hours and the kind of control is described. The distribution of hours by sections and topics is considered. The compulsory learning outcomes are formed into groups such as the requirements for students' knowledge and skills, as well as the purpose, tasks, methodological support and recommended literature for all curriculums. It is proposed to introduce separate educational disciplines such as "Mycology" and "Theology" in the curriculum of the students-future Biology teachers.

This study contributes to the service learning (SL) literature by providing new empirical evidence of learning from a problem-based SL research project conducted in a developmental research methods course. Two sections of the course taught in a traditional manner were compared to two sections of the course taught with an integrated SL project involving a local Boys & Girls Club. Pre- and posttest scores of the groups were compared in regard to content knowledge, civic engagement, and perceptions of the course. Results indicated that the SL students outperformed the control courses in learning outcomes. Civic engagement did not significantly change over the course of the semester. Student preference data indicated that most enjoyed the SL course, found it helpful, and thought it contributed to their understanding of the course material. The findings are related to past research and theoretical underpinnings that support SL.

The most important components of living cells such as carbohydrates, proteins and nucleic acids are the polymeric molecules. Nature utilizes polymers both as constructive elements and as a part of the complicated cell machinery of living things. The rapid advancement in biomedical research has led to many creative applications for biocompatible polymers. With the development of newer and more potent drugs, a parallel expansion in more sophisticated drug delivery systems becomes mandatory. Smart polymeric drug-delivery systems have the ability to respond to environmental changes and consequently, alter their properties reversibly enabling an efficient and safe drug delivery. This review comprehensively discusses various aspects of these polymers classified in different categories as per the type of stimulus.

The ArgumentWhen economists report on research using mathematical models, they use a literary form similar to the experimental report in the laboratory sciences. This form consists of a narrative of a series of events, with a clear temporal segregation of the agency of the author and the agency of the objects of study. Existing explanations of this literary form treat it as a rhetorical device that either conceals the agency of the author in constructing and interpreting the findings, or simply appropriates the appearance of accepted (natural-)scientific method. This article — based on analysis of a research program in economics, a single article that issued from that program, and in-depth interviews with the authors — proposes an alternate interpretation. Drawing on the praxeological “laboratory studies” tradition in science studies, we treat work with mathematical models as involving the interaction of economists with objects (models) that act independently of the analyst's will. The clear separation of the economist's and the models agency, as depicted in the published report, is not the result of a rhetorical rewriting of actual events, but is a practical accomplishment. Every step in the analytical work that preceded the paper is devoted to developing a procedure in which the economists' agency will be completely accountable in terms of accepted practices, and the performance of the model will be distinct and compelling.
