The aim of this research was to investigate the ability of the 8-9th grade students to write chemical formulas and equations of reactions. Verhovskij’s method, which involves using white and full-colour paper cards, was proposed as a chemistry teaching method for students. Some of the students suggested using non-paper-based cards, i.e. “domino sticks”. The obtained results proved that students who had participated in the building blocks activity showed significantly higher post-test scores than students who had not participated. The average grade of the students who used the cards for chemical formula formation and reaction equations increased respectively by 1.30 and 1.20. The average grade for writing and balancing of the reactions equations was lower because balancing requires strong knowledge in mathematics. The results have shown that the use of cards is a good method at an early stage of chemistry education. \u0000Keywords: general chemistry, hands-on learning, domino-stick, graphical formula, reaction equation.","PeriodicalId":222493,"journal":{"name":"GAMTAMOKSLINIS UGDYMAS / NATURAL SCIENCE EDUCATION","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124474714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was discussed about the exceptional geological exhibit importance to non-formal natural science education and about Lithuanian and Latvian student attitude to natural science disciplines and mathematics. Traditionally, methodological natural science education questions were discussed. One plenary report was made remotely. Dr. Solange W. Locatelli from Brazilian Federal ABC university shared her personal experience applying metacognitive strategies in chemistry teaching.\u0000Most conference reports were presented in the form of articles and published in the conference proceedings.

Conference participants had a unique possibility to get acquainted with the lagoon district, to see off the Sun, and also to taste traditional lagoon fish soup.\u0000On the second conference day, the reports were also presented. It was discussed about teaching based on researching. The main report idea was educational activity object selection and pedagogical scenarios preparation. Pilot empirical research results were presented. Natural science education organisation and improvement in a primary school was discussed. The carried-out research allows stating, that primary school teacher professional preparation in a natural education sphere remains actual. Practical work organisation is considered the most appropriate activity. The teachers try the least to satisfy / to take into consideration individual students’ differences.

The student himself has to be an active teaching/learning process participant but not a passive listener in the lesson. Not only subject or general competencies, positive emotions are acquired when students actively take part in the lesson, do a particular task but also students are made to involve critical thinking into their activity. \u0000 Not so few other general education subjects taught at school are integrated into geography subject teaching/learning programme. Learning geography, students very often have to use their history, biology, chemistry, physics, natural science and other subject knowledge. Every student’s individual abilities are also of quite a big importance learning geography. Seeking for the students to easier acquire the provided knowledge, learn to learn independently during geography lessons, be able to apply this knowledge in practice, it is important to concentrate students’ attention and activity, to encourage their creativity. It is very important for the students to learn to work individually and in a group. The most important thing is not only to acquire knowledge and general competencies but also learn to learn!\u0000 Geography subject teaching is inseparable from information and communication technologies (ICT), which diversify geography teaching a lot. Using them, one can assign for the students to do practical tasks, their knowledge from geography subject can be checked. Also, it is very important that the use of ICT in the lesson allows students to acquire more self-confidence, because very often students carry out such tasks independently.\u0000 Independent work task assignment in the lesson is very useful for those, who have less abilities. They need more time for carrying out the tasks. The tasks carried out independently during geography lessons, allow students to acquire geography knowledge and general competencies under favourable conditions, at a favourable pace of learning.\u0000Considering that not equal ability students take part in the lesson, it is important to model the lesson so, that all students successfully realise themselves in it, acquire the maximum knowledge and abilities. For that, it is necessary to individualise and differentiate the tasks for the students. The tasks have to be selected both for higher and lower ability students.\u0000 Teaching geography, a few student individualisation and differentiation application methods are possible. It depends on whether a new teaching topic is given in the lesson, whether it is a revision, knowledge generalisation lesson. Individualised and differentiated tasks can be applied during the whole geography lesson. Students can be given individualised and differentiated tasks, doing concrete tasks, for example, during students’ independent work task. \u0000It is important to share the experience about the application o","PeriodicalId":222493,"journal":{"name":"GAMTAMOKSLINIS UGDYMAS / NATURAL SCIENCE EDUCATION","volume":"546 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130406802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
