To describe the behavior of matter and energy, chemists classify them in three distinct domains: macroscopic, microscopic, and symbolic. The ability to use these three representations is the basis for understanding concepts in chemistry. This study aims to analyze students' ability to identify symbolic representations in chemistry. The research design uses a one shot case study. The subjects of this study were students of prospective science teachers as many as 85 students. Data collection techniques using tests and rubrics. The results showed that of the ten symbolic representation statements, only three statements achieved the highest percentage of correct answers, namely statements about writing ionization reactions and writing electron symbols. There are two statements where almost 90 percent of students answered incorrectly. The statement is about reversible or irreversible reaction equations and exothermic reaction equations. From this research, it can be concluded that students' ability to identify symbolic representations in chemistry still needs to be improved, because the average score is still low.

This paper is a qualitative case study designed to identify prospective science teachers mathematical-logical structures on the basis of their knowledge and achievement levels in magnetism. The study also made an attempt to reveal the effects of knowledge-level variables and procedural variables, which were considered to be potential factors, on the teachers knowledge and achievement levels. The participants knowledge level was represented by the APS score (knowledge-level variable), whereas their achievement level was expressed by the ASS score (achievement level). The prospective teachers knowledge and achievement levels in mathematical logic were 0.204 and 0.305, respectively. The knowledge-level variables were given-asked, formula, and operation. On the other hand, the procedural variables consisted of formula knowledge, basic math knowledge, and scientific knowledge. The latter group of variables had the following values, respectively: 0.336, 0.758, and 0.199. The findings indicated that basic math knowledge led the participants to have an achievement level higher than their knowledge level. The other variables had values similar to those of the knowledge and achievement levels.

ABSTRACTTraffic accidents involving minors are increasing every year. It was recorded that in the period 2015-2019, more than 139,000 underage motorists were the perpetrators of traffic accidents or an accumulation of around 16% of the total number of accidents in Indonesia. This study aims to discuss the behavior of children after being allowed to ride a motorbike and how parental supervision is concerned with this. This study used a qualitative approach with a case study research design. Data collection techniques were carried out through field observations and direct interviews with informants. The results of the study show 1) The licensing factor from family or parents, the efficiency of time used, as well as invitations from friends and lifestyle, affect minors who already use motorbikes, 2) The impact of underage motorists is a manifestation of self-existence by following the tracks and daring to modify the motorbike on the pretext of making it look cooler. 3) Parents have a very important role in supervising underage rider.ABSTRAKKecelakaan lalu lintas yang melibatkan anak di bawah umur semakin meningkat di setiap tahunnya. Tercatat dalam rentang tahun 2015-2019, lebih dari 139.000 pengendara di bawah umur menjadi pelaku kecelakaan lalu lintas,atau diakumulasi sekitar 16% dari jumlah total kecelakaan di Indonesia. Penelitian ini bertujuan untuk membahas perilaku anak pasca diperbolehkannya mengendarai motor dan bagaimana pengawasan orang tua dalam menyikapi hal tersebut. Penelitian ini menggunakan pendekatan kualitatif dengan desain penelitian studi kasus.Teknik pengumpulan data dilakukan melalui observasi di lapangan dan melakukan wawancara secara langsung kepada informan. Hasil dari penelitian menunjukkan 1) Faktor perizinan dari keluarga atau orang tua, efisiensi waktu yang digunakan, serta ajakan dari teman dan gaya hidup mempengaruhi anak di bawah umur sudah menggunakan motor, 2) Dampak dari pengendara motor di bawah umur ini merupakan wujud untuk menunjukkan eksistensi diri dengan mengikuti trek-trekan serta berani memodifikasi motor dengan dalih biar terlihat lebih keren.3) Orang tua memiliki peranan yang sangat penting dalam mengawasi pengendara di bawah umur, Pola pengasuhan yang diterapkan oleh orang tua sangat mempengaruhi pola perilaku dan juga proses pembentukan karakter anak.

Pre-service teachers’ first experiences and ideas prior to application affect their teaching activities. For this reason, it is aimed to determine transferring the experiences and ideas of prospective science teachers before lesson activities and its development with lesson activities. The study was carried out with 29 third year prospective teachers who attended the course named Laboratory Application II and undergraduate students at the Department of Science Education at Karadeniz Technical University during 2012-2013 spring semesters. The study was conducted by case study design. Thirty-minute lesson activities were carried out by them. Reflective writings constituted by candidates, lesson observations and plans were used as data collecting tools. They were examined through inductive thematic analyze. When compared before and during lesson activities process, it was determined that pre-service teachers’ perception, ideas or application had changed at some concepts. This case might be a proof of development of pre service teachers’ professional skills doing practice.
