This study was carried out with a total of 75 students attending 9th grade in two high schools affiliated to the Ministry of National Education in Reyhanlı district, which hosted many Syrian refugees in Hatay province in the spring semester of 2018-2019 academic years and lasted for three weeks. A total of 75 students, 43 from two different 9th grade classes taught by the same teacher from the first high school, and 32 from the other high school, participated in the study. Two of these classes were assigned as the control group and one as the experimental group. While the symbolic language of chemistry was taught with the traditional teaching method in the control groups, an educational game with Arabic support was used in the experimental group based on the constructive learning approach. Prior knowledge, attitude-perception towards chemistry, and chemistry achievement tests were applied to all three groups before the implementation in order to control their prior knowledge and attitude and perception towards chemistry; the chemistry success test was applied again after the implementation. ANCOVA analysis was used to evaluate the data obtained from the tests. As a result of the study, it was concluded that High school 9th-grade students studying with the educational game based on constructivist learning approach had significantly higher mean score in the chemistry achievement test on the symbolic language of chemistry than the students studying with traditional teaching method, they relate the concepts more accurately, and performed more meaningful learning.

Both attitude and previous experiences play a large role in shaping a student’s approach to and achievement in a given subject. Similarly, students’ enjoyment of their learning experiences is an important factor in determining their retention in their course of choice. Here, we explore the attitudes toward the study of chemistry amongst a cohort of first-year undergraduate students at a regional Australian university, including assessing these parameters at the beginning of their first term, the end of the first term and the end of their second term. In addition, metrics on the students’ experiences of studying chemistry were collected at the latter two timepoints. Generally, student attitudes toward chemistry were positive, as were student learning experiences in most instances. Two-step cluster analysis revealed the presence of two distinct clusters of students within the data, differing significantly in their overall attitude toward the study of chemistry. Students who had studied chemistry in Year 12 did not show any significant differences in their attitudes toward chemistry, when compared to students who had not studied Year 12 chemistry; however, their learning experiences in first-year chemistry were rated as being significantly more positive. We attribute this to their increased ability to engage with and successfully learn from the topic material presented in lectures and tutorials, as their previous exposure to the ‘language’ of chemistry may provide them with an advantage over chemistry-naïve students.

The language used within different disciplines has become fully separated. The language of chemistry is based on chemical names, where it is shown how atoms are disposed through chemical or covalent bonds to yield molecules, On the other hand, assigning a name contains as an added bonus the indication of which heuristic way/ways are suitable to prepare them that to transform an initial situation (reagents) to a final one (Products). In big molecules (homo and hetero polymers) chemical bonds are not sufficient per se to describe molecules, but the spatial conformations such molecules take are dictated by the bonds structure. The way molecules change answering a change in the environment are appropriate for a universe changing though smooth steps, not via shots.

The way chemists represent chemical structures as two-dimensional sketches made up of atoms and bonds, simplifying the complex three-dimensional molecules comprising nuclei and electrons of the quantum mechanical description, is the everyday language of chemistry. This language uses models, particularly of bonding, that are not contained in the quantum mechanical description of chemical systems, but has been used to derive machine-readable formats for storing and manipulating chemical structures in digital computers. This language is fuzzy and varies from chemist to chemist but has been astonishingly successful and perhaps contributes with its fuzziness to the success of chemistry. It is this creative imagination of chemical structures that has been fundamental to the cognition of chemistry and has allowed thought experiments to take place. Within the everyday language, the model nature of these concepts is not always clear to practicing chemists, so that controversial discussions about the merits of alternative models often arise. However, the extensive use of artificial intelligence (AI) and machine learning (ML) in chemistry, with the aim of being able to make reliable predictions, will require that these models be extended to cover all relevant properties and characteristics of chemical systems. This, in turn, imposes conditions such as completeness, compactness, computational efficiency and non-redundancy on the extensions to the almost universal Lewis and VSEPR bonding models. Thus, AI and ML are likely to be important in rationalizing, extending and standardizing chemical bonding models. This will not affect the everyday language of chemistry but may help to understand the unique basis of chemical language.

The everyday language of chemistry uses models, particularly of bonding, that are not contained in the quantum mechanical description of chemical systems. To date, this everyday language has overlapped strongly with that (the ontology) of artificial intelligence (AI) and machine learning (ML). Within the everyday language, the model nature of these concepts is not always clear to practicing chemists, so that controversial discussions about the merits of alternative models often arise. However, the extensive use of AI and ML in chemistry will require that these models be extended to cover all relevant properties and characteristics of chemical systems. This in turn imposes conditions such as completeness, compactness, computational efficiency and non-redundancy on the extensions to the almost universal Lewis and VSEPR bonding models. Thus, AI and ML are likely to be important in rationalizing and standardizing chemical bonding models. This will not affect the everyday language of chemistry but may help understand the unique basis of chemical language.

The language of chemistry has seldom been the object of study by linguists, who tend to prioritize literary works. Nevertheless, in recent years its study has developed, at a different pace for each of the Romance languages. It is therefore important to describe the current state of research separately for French, Spanish, Italian, Portuguese, Romanian, and Catalan. The work of historians of science, who have always dedicated particular attention to the language of chemistry, is particularly pertinent to this purpose. Toward the end of the 18th century, French chemists spearheaded a terminological revolution: traditional terms used in alchemy were replaced by a well-structured, systematic nomenclature that was quickly adopted by the scientific community, mainly through the translation of French chemical texts, many of which were pedagogical in nature. It is important to trace the dissemination process of new chemical nomenclature in each country and in each language, since it was not uniform. This new nomenclature is firmly based on the classical languages, particularly Greek, and it adopts a broad range of suffixes and prefixes for systematization. During the 19th century, this system steadily consolidates as the field of chemistry develops, until a standardized international nomenclature is established. From a lexicographical standpoint, the treatment of chemical terms in both general and specialized dictionaries deserves attention. Traditional lexicography has mistakenly classified many chemical terms as Hellenisms, while from the early 21st century onward they have been recognized as Gallicisms thanks to research carried out by historians of scientific language. Finally, the procedures the Romance languages follow to coin chemical terms—both to name elements and chemicals and to express chemical combinations by means of word formation processes—must be taken into account.

Abstract To chemists and chemical educators, there were two important events in the ‘60s and ‘70s. First, in 1961, the agreement between physicists and chemists on the choice of carbon 12 as unique element of reference in the atomic weights table and then in 1971, the definition of mole as the seventh unit of the international system [1]. In both of these issues the Union played its role as expert to the fullest, and established solid grounds for a common language of chemistry across the world. This role is also extended to other matters at a time marked by social changes. Technological progress improved quality of life like never before and the space conquest that opened new horizons, both scientific and technological, to explore. All the while, despite the Cold War, international and interdisciplinary projects are established, and new international organizations, such as UNESCO, appear to cope with the new challenges. Alongside these organizations, the longstanding ICSU and the Union adapt themselves.

Penelitian ini bertujuan untuk mengetahui miskonsepsi materi larutan penyangga, persentase miskonsepsi pada setiap indikator materi larutan penyangga, dan penyebab terjadinya miskonsepsi materi larutan penyangga pada siswa SMA Negeri 2 Mataram. Penelitian ini merupakan penelitian deskriptif kualitatif yang melibatkan 80 siswa kelas XI IPA 4 dan XI IPA 5 SMA Negeri 2 Mataram sebagai sampel dalam penelitian yang ditentukan secara purposive sampling. Instrumen yang digunakan untuk menganalisis miskonsepsi larutan penyangga yaitu instrumen multiple choice two tier diagnostic. Instrumen di validasi oleh expert judgment dan validasi empirik oleh 38 siswa kelas XII IPA 2 SMA Negeri 2 Mataram.. Hasil analisis miskonsepsi larutan penyangga menggunakan instrumen two-tier multiple choice diagnostic menunjukkan bahwa terjadi miskonsepi sebesar 47%, memahami konsep sebesar 37%, dan tidak memahami konsep sebesar 16%. Miskonsepsi terbanyak terjadi pada indikator konsep perhitungan pH larutan penyangga pada penambahan sedikit asam atau basa sejumLah 4 soal yaitu dengan rata-rata 64,08%. Miskonsepsi larutan penyangga terjadi karena guru kurang menekankan materi konsep, khususnya pada indikator larutan penyangga pada kehidupan sehari-hari, bahasa buku teks kimia yang terlalu sulit, dan siswa sendiri yang kurang fokus saat proses pembelajaran. Misconceptions on buffer solution AbstractThis study aims to determine the misconception on buffer solution, the percentage of misconceptions on each indicator, and the cause of the misconception of the student of SMA Negeri 2 Mataram.This research is a qualitative descriptive study involving 80 students of class XI of physics study (IPA) 4 and XI 5 of SMAN 2 Mataram as samples determined by purposive sampling. The instrument used to analyze the misconceptions of the buffer solution is two-tier instrument diagnostic multiple choice. The instrument is validated by expert judgment and empirical validation by 38 students of class XII physic study (IPA) 2 SMA Negeri 2 Mataram. The results of the data analysis showed that there is 47% misconceptions, 37% understand and as many as 16% do not understand concept. Misconceptions occurred in the calculation of the indicator concept pH buffer solution in the addition of a small amount of acid or base in an average of 64.08%. The misconception of the buffer solution occurred because the teachers did not emphasize the concept of matter, particularly on indicators of the buffer solution in everyday life, the language of chemistry textbooks that are too difficult, and the students themselves are less focused during the learning process.
