A study was developed to compare secondary high school students' knowledge and attitude changes toward environmental issues after the completion of an interdisciplinary instructional unit in environmental science. The population for the study was high school horticulture and environmental science students. The study consisted of four student groups, including two control groups and two experimental groups, one each from an environmental science class and a horticulture class. The control groups did not participate in the treatment, which consisted of an environmental mini-unit and plant propagation experiment that the experimental groups completed. Both student groups responded to a pre- and posttest questionnaire. There were no significant differences in overall attitude scores between treatment and control groups. Significant differences were noted in knowledge gains between the horticulture control group and treatment group, with students participating in the mini-unit scoring significantly higher in knowledge gain. There was also a positive correlation between attitude scores of students who had success with their propagation experiments. The results of this study indicate that it is important to test students' attitudes and knowledge when determining the effectiveness of new environmental curriculum. The high correlation between success in the propagation experiment included in the miniunit and attitude supports findings that an activity-based curriculum has the potential to raise the awareness of students on environmental issues.

Environmental Protection Policies

During the fall of 1965, a small group of people living on central Long Island, New York, with interests and concerns about a variety of environmental issues had begun to meet monthly in each other’s living rooms. Attendance of 25 to 30 included scientists from Brookhaven National Laboratory and the State University of New York at Stony Brook, in addition to various conservationists and a few high school students. The group called itself by the noneuphonious name of Brookhaven Town Natural Resources Committee, which quickly became BTNRC for obvious reasons. BTNRC was fascinating and enjoyable, but hardly an organization. There was no office, staff, money, bylaws, elected officers, or any of the other ingredients usually present in an organization. It was just a group of people who met occasionally to foster environmental protection policies by our local governments, and we all had other daytime jobs. We discussed various environmental issues—pollution from duck farms, dredging of wetlands, sewage pollution, DDT use on local marshes, dump sites, groundwater protection, wildlife and habitat preservation, and so forth. Meetings usually ended with one-person committees assigned to go do something during the weeks that followed, typically writing a letter to a congressman, a local politician, or a local newspaper. There was no treasury or treasurer, so occasionally we tossed a dollar or two into the middle of the room so that Myra Gelband, one of Art Cooley’s dedicated high school students, could send postcards to announce the next meeting. Attendance was excellent because meetings were fun with good company, good humor, and coffee and donuts at the end. The only feature of this nonorganization was that we had a letterhead printed to give the impression that there was, in fact, such an organization. We needed a bit of puffery to appear greater than we were, for otherwise we feared nobody would listen to us. Everyone seemed to like each other and got along well. An enjoyable social mix is surely a motivational factor that helps explain which groups continue and grow, and which ones stagnate.

Navigation Patterns

Augmented reality (AR) has the potential to fundamentally transform science education by making learning of abstract science ideas tangible and engaging. However, little is known about how students interacted with AR technologies and how these interactions may affect learning performance in science laboratories. This study examined high school students’ navigation patterns and science learning with a mobile AR technology, developed by the research team, in laboratory settings. The AR technology allows students to conduct hands-on laboratory experiments and interactively explore various science phenomena covering biology, chemistry, and physics concepts. In this study, seventy ninth-grade students carried out science laboratory experiments in pairs to learn thermodynamics. Our cluster analysis identified two groups of students, which differed significantly in navigation length and breadth. The two groups demonstrated unique navigation patterns that revealed students’ various ways of observing, describing, exploring, and evaluating science phenomena. These navigation patterns were associated with learning performance as measured by scores on lab reports. The results suggested the need for providing access to multiple representations and different types of interactions with these representations to support effective science learning as well as designing representations and connections between representations to cultivate scientific reasoning skills and nuanced understanding of scientific processes.

The quality of the water is a term that doesn't only concern the determination of the purity of the same, but the characteristics also wished for your use. The teaching of Environmental Chemistry using the thematic water quality, linked to the experimental activities it can contribute to global formation of high school students giving them conditions for construction, reconstruction and production of knowledge. This way this work had as objective the construction of a mini-course for high school students, in order to these can relate the chemistry studied with some parameters related to the water quality through experimental activities. In the development of this mini-course a potability kit was used (Alfakit) for analysis of the following parameters: alkalinity, chloride, free chlorine, pH, total hardness, turbidity, color, total iron, consumed oxygen, ammonia, total coliforms, faecal coliforms and salmonella (salmonella typhi). The analyses were accomplished as standard methods for the water and wastewater. It was also made a plan and class procedure and a questionnaire given to the participant students. The results obtained starting from the determination of the parameters, already mentioned, they allowed to collaborate for the students to observe subjects related to the consumption, quality and preservation of the water. We believed that with the student participation activates in a situation of real investigation, proposal in the challenge form will be able instigate the students in the search of an answer more consolidated.

Resumo: Discussões a respeito de questões ambientais têm conquistado espaço na sociedade e a escola como uma das principais instituições de socialização do ser humano possui um papel fundamental no desenvolvimento de uma Educação Ambiental emancipatória, capacitando o indivíduo para viver harmonicamente com o Meio Ambiente. O objetivo da pesquisa foi analisar a concepção dos alunos do Ensino Médio de uma instituição pública do município de Uniflor sobre Educação Ambiental, além de buscar compreender a percepção sobre Meio Ambiente como participantes das ações humanas na natureza. Os dados foram coletados por meio de questionários e os resultados indicaram uma concepção totalmente conservacionista de Meio Ambiente. Logo, os professores desses alunos, ao planejarem atividades em Educação Ambiental, devem considerar esses resultados a fim de construir, coletivamente com toda a comunidade escolar, um conceito de Meio Ambiente mais amplo e crítico.Palavras-chave: Questões ambientais; Conservacionista; Escola. Abstract: Discussions about environmental issues have gained space in society and the school as one of the main institutions of socialization of the human being has a fundamental role in the development of an emancipatory Environmental Education, enabling the individual to live in harmony. with the Environment. The objective of the research was to analyze the conception of High School students of a public institution in the city of Uniflor about Environmental Education, as well as to understand the perception of Environment as participants of human actions in nature. The data were collected through questionnaires and the results indicated a totally conservationist conception off environment. Therefore, the teachers of these students, when planning activities in Environmental Education, must consider these results in order to build, collectively with the whole school community, a broader and critical environment concept.Keywords: Environmental issues; Conservationist; School.
