摘要

科学实验室是科学教学的重要资源投入。学生在科学实验室进行实践实验,加强了对科学的学习,提高了对科学的理解水平。由于化学是科学的一个分支,它也应该辅以实践活动。本研究旨在评估东Gojjam地区中学和预科学校化学实验室和实践活动的现状。采用随机抽样的方法对研究区学生和化学教师进行数据采集。采用结构化和半结构化问卷调查和实验室观察。教师和学生在研究领域的反应一致认为,实际的实验室工作对学习化学的重要性很高。结果表明,9年级和10年级的学生很少在实验室做实际工作,而11年级和12年级的学生有时会在实验室做实际工作。这可能就是为什么只有8688名(11.5%)学生进入了自然科学领域的原因之一。东Gojjam区教育局报告。预备学校的学生在他们自己的化学课本上列出的实验中也只进行很少的实验活动。正如教师给出的不使用实验室工作来教授化学的原因是因为缺乏化学品和仪器,害怕化学品,缺乏行政支持,实验室组织不良,没有时间分配给实际的实验室工作,实际的实验室工作不被认为是教师的教学负担,缺乏对如何使用实验室进行化学教学的实验室培训。一般来说,上述问题阻碍了实验室的实践活动,使研究区中学学生缺乏参加科学课的兴趣。关键词:实验室,中小学,实践活动,化学。出版日期:2020年10月31日

Status of Chemistry Laboratory and Practical Activities in Secondary and Preparatory Schools of East Gojjam, Ethiopia
Science laboratory is a very important resource input for teaching science. Learning science is enhanced and the understanding level is improved when students are engaged in science laboratory for practical experiments. Since chemistry is a branch of science, it should be also assisted with practical activities.  The current study aimed to assess the status of chemistry laboratory and practical activities in secondary and preparatory schools of East Gojjam zone. A random sampling technique was employed to collect data from students and chemistry teachers of the study area. Structured and semi-structured questionnaires and observation of laboratories was used. Both teacher’s and student’s response in the study area agree on the significance of practical laboratory works to learn chemistry is very high. The result shows as Grade 9 and grade 10 students never do practical work in the lab but grade 11 and grade 12 students sometimes conduct practical work in the lab. This may be one of the reasons why only 8,688 (11.5%) students have joined the natural science field according to the 2009E.C. East Gojjam Zone Educational Bureau report. Preparatory school students also conduct only few experimental activities among the experiment listed in their own chemistry text book. As teachers give the reasons on why laboratory work is not used to teach chemistry is because of lack of chemicals and apparatuses, fear of chemicals, lack of administration support, the lab is poorly organized, no time is allotted for practical lab work, practical lab work is not considered as a teaching load for teachers and lack of laboratory training on how to use laboratory to teach chemistry in high and preparatory schools. Generally the above problem hinders practical activities in the laboratory and makes students at secondary schools of the study area lack interest to join science class. Keywords: Laboratory, secondary and preparatory school, practical activity, chemistry. DOI: 10.7176/CPER/63-02 Publication date: October 31 st 2020
