“…Model mental biasanya berkembang sesuai dengan kebutuhannya dalam membuat prediksi dan menyelesaikan permasalahan dalam belajar kimia (Halim, 2013). Menurut Borges & Gilbert, Greca & Moreire setiap orang menggunakan model-model mental ini untuk melakukan upaya memecahkan suatu masalah melalui proses menalar, menjelaskan, memprediksikan fenomena, atau menghasilkan model yang diekspresikan dalam berbagai bentuk (seperti diagram, gambar, grafik, simulasi atau pemodelan, aljabar, bahkan juga, deskripsi verbal dengan kata-kata atau bentuk tulisan cetak, dan lain-lain), kemudian dapat dikomunikasikan pada orang lain (Sunyono,2013).…”

The Effect of Socioscientific Issues to Improve Mental Models of Student Ability on Electrolyte and Nonelectrolyte Solutions Topic. This research was aimed to describe the effect of sosioscientific issues to improve mental models of student ability on electrolyte and nonelectrolyte solutions topic. This research method used quasi experiment with pretest posttest control group design. The population of this research were all students of X IPA. The sample was obtained by cluster random sampling technique and it was obtained sample was students of X IPA 3 as experiment class and X IPA 6 as control class. The effect of socioscientific issues was analyzed by the differences of two average test and effect size test to mental models of student ability compared with control class. The result showed that using socioscientific issues on learning had large effect to improve mental models of student ability. Based on hypothesis testing, it can be concluded that learning using Socioscientific Issues has a large effect to improve mental models of student ability..

Penelitian ini bertujuan untuk mendeskripsikan pengaruh pembelajaran isu sosiosaintifik dalam meningkatkan kemampuan model mental siswa pada materi larutan elektrolit dan non-elektrolit. Metode penelitian ini yaitu kuasi eksperimen dengan pretest-postest control group design. Populasi yang digunakan adalah seluruh siswa kelas X IPA. Pengambilan sampel dilakukan dengan cara cluster random sampling sehingga diperoleh kelas X IPA 3 sebagai kelas eksperimen dan X IPA 6 sebagai kelas kontrol. Pengaruh pembelajaran isu sosiosaintifik dianalisis menggunakan uji perbedaan dua rata-rata n-Gaindan uji effect size terhadap kemampuan model mental siswa dibandingkan dengan kelas kontrol. Hasil penelitian menunjukkan bahwa pembelajaran berbasis isu sosiosaintfik memiliki pengaruh yang besar dalam meningkatkan kemampuan model mental siswa. Berdasarkan pengujian hipotesis, dapat disimpulkan bahwa pembelajaran menggunakan isu sosiosaintifik memiliki pengaruh yang besar dalam meningkatkan model mental siswa.

“…Senyawa tersebut berwujud cair karena gaya tarikmenarik antarmolekulnya lebih lemah. Temuan ini sejalan dengan hasil penelitian Halim et al (2012) yang menyimpulkan bahwa siswa mengalami kesulitan ketika menggambarkan senyawa kimia dalam tiga representasi kimia (makroskopis, submikroskopis dan tingkat simbolik). Dari hasil wawancara diperoleh ada beberapa faktor yang menyebabkan terbentuknya model mental alternatif pada materi ikatan ion dan ikatan kovalen.…”

ABSTRAKPenelitian ini bertujuan untuk mendeskripsikan dan menjelaskan profil model mental siswa, serta menganalisis faktor-faktor yang memengaruhi terbentuknya model mental alternatif siswa kelas X MIA di SMA Laboratorium Undiksha Singaraja pada materi ikatan ion dan ikatan kovalen. Penelitian ini menggunakan pendekatan mix methods, jenis sekuensial. Pengumpulan data dilakukan dengan observasi, tes model mental, dan wawancara. Instrumen yang digunakan adalah tes diagnostik pilihan ganda dua tingkat dan wawancara dengan pertanyaan menyelidik. Hasil penelitian menunjukkan persentase siswa yang memiliki model mental ilmiah tentang ikatan ion dan kovalen sebanyak 53,33% model mental alternatif sebanyak 38,89%, dan 7,78% tidak memberikan tanggapan. Faktor-faktor yang memengaruhi terbentuknya model mental alternatif meliputi kekurangan informasi, kekeliruan penalaran, dan buku teks kimia yang digunakan siswa sebagai sarana belajar. Sehubungan dengan temuan tersebut, guru kimia di SMA perlu menerapkan strategi pembelajaran yang tepat untuk mengajarkan ketiga level kimia secara utuh.Kata Kunci: ikatan ion, ikatan kovalen, model mental, model mental alternatifABSTRACTThis research was aimed to describe and explain the profile of mental model student’s, and analyze the factors that influence the formation of alternative mental models of class X MIA students at SMA Laboratorium Undiksha Singaraja about ionic bonding and covalent bonds material. This research is a mix method approaches in research, a sequential type. Data collection is done by observation, mental model tests, and interviews. The instrument used in this study was a diagnostic test two tier and interview with probing questions. The results showed the percentage of students who experienced a scientific mental model of ion bonds and covalent bonds of 53.33% of students, had an alternative mental model of 38.89%, and as many as 7.78% did not have a mental model. Factors that influence the formation of alternative mental models include lack of information, errors of reasoning, and chemical textbooks that students used. Related with that research, chemistry teachers in high schools need to apply appropriate learning strategies in the process of learning chemistry.Keywords: ionic bonding, covalent bonding, mental model, mental model alternative

“…Three levels of chemistry representations are connected and reflected on students' mental model (Chittleborough et al, 2002). The development of mental model is commonly used to predict, test new concepts Article of Thesis, HIDAYATI, 161760004/2016, MAGISTER PENDIDIKAN KIMIA FMIPA UNIVERSITAS NEGERI PADANG, APRIL 2018 and solve the problems in science instructions (Halim et al, 2013). A teacher should know how students develop their own mental model in order to ensure they do not do it mistakenly because mental model is the essential part in constructing a theory and chemistry practices (Nahum et al, 2004;Coll, 2008).…”

Mole concept is the essential part of chemistry learning and has been the prerequisite to learn other chemistry concepts. Learning source used has not yet connected the three levels of representations completely. The inability to connect the three levels of representations might affect students’ learning outcome and mental model. This study aims to find out the effect of structured inquiry based module on students’ mental model of mole concept. The design of study is Randomized Control Group Postest Only Design. There were 141 students from two Senior High Schools in Padang recruited as the samples of study. The instruments are two-tier mental diagnostic test and semi structured interview. The result of t-test on hypotheses reveals that the mental model of mole concept in experimental group was higher than that of control group of both schools. Hence, it can be said that there is effect of module on students’ mental model of mole concepts in both schools
