Chemical bonding was one of the subjects considered difficult by students, because it had submicroscopic concept that learns about the formation of bonds an element that was quite difficult for students to understand. The development of teaching material in the form of teaching materials was seen as a solution to this problem. This study aimed to develop chemical bondinginquiry modelsteaching materials with conflict cognitive strategies towards critical thinking skills. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. The development results were validated by three expert validators, one practitioner validator and ten IKIP Mataram students as students' limited test validators. Quantitative data from the results of feasibility validation and the results of the assessment of student attitudes toward critical thinking skills were analyzed by percentage formula and the results of effectiveness test data were calculated by N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator was used as a consideration to make revisions to the instructional materials developed. In general, the validator's assessment of the results of the development obtained an average percentage of 83.80%, 85.71%, 88% and 85.71%. While the results of the analysis of effectiveness using the N-gain test obtained an average score of 0.6 with the medium category and analysis. This showed that the teaching materials developed were very feasible to proceed to a broader and more effective stage to foster critical thinking skills.

Dalam mata kuliah kimia dasar II, mahasiswa belum mampu menerapkan keterampilan berpikir kritis, berpikir kreatif, dan proses sains secara maksimal. Oleh sebab itu mahasiswa sering tidak memahami dengan baik, kehilangan arah, tidak dapat memberi alternatif dalam proses penyelesaian permasalahan kimia baik di kelas maupun laboratorium. Penerapan Context-rich Problems dapat mendorong mahasiswa untuk menerapkan kemampuan berpikir kritis, kreatif, dan proses sains secara maksimal. Penelitian ini bertujuan untuk mengetahui pengaruh Context-rich Problems terhadap keterampilan berpikir kritis, berpikir kreatif, dan proses sains mahasiswa dalam mata kuliah kimia dasar II. Penelitian ini dilaksanakan dengan rancangan quasy eksperimental. Subjek penelitian adalah mahasiswa tahun pertama Fakultas Pendidikan Matematika dan IPA IKIP Mataram tahun pelajaran 2014/2015. Hasil penelitian menunjukkan bahwa penerapan context-rich problems dapat menyebabkan keterampilan berpikir kritis, keterampilan beprikir kreatif dan keterampilan proses sains mahasiswa lebih baik dalam mata kuliah kimia dasar II daripada tanpa contet-rich problems. Hal ini ditunjukkan melalui skor rata-rata kemampuan beprikir kritis mahasiswa di kelas eksperimen (67,85) lebih baik daripada kelas kontrol (54,61) dengan uji t-polled varians, diperoleh thitung = 3,56 > ttabel = 1,99 pada taraf signifikan 5%. Skor rata-rata keterampilan berpikir kreatif kelas eksperimen (71,80) lebih tinggi daripada kelas kontrol (61,54) dengan thitung > ttabel (4,67 > 2,008) pada taraf signifikan 5%. Nilai rata-rata keterampilan proses sains kelas eksperimen (74) lebih tinggi daripada kelas kontrol (63). Dengan hasil uji kolmogorov-smirnov, terhadap data keterampilan proses sains siswa menunjukkan KD hitung = 0,34 > KD tabel = 0,29 pada taraf signifikan 5%.

This development aims to determine the characteristics and feasibility of multipleinquiry-based representation modules in the reaction rate material through theADDIE stage (Analyze, Design, Development Implementation and Evaluation)developed by Thiagarajan. This research and development was carried out untilthe development stage with adjustments based on development needs. Theassessment instrument used to determine the feasibility of the module is aquestionnaire sheet. The module feasibility was assessed by 2 material experts, 1media expert, 1 linguist, 1 colleague, 1 practitioner, and 10 students as subjects.Students involved in this study came from chemistry education study programsthat had undergone basic chemistry courses through limited trials. The data onthe value of the grievances obtained are still in the form of qualitative data andthen processed into quantitative data. Quantitative data are analyzed for eachaspect of the assessment. The final score obtained is converted to the level ofproduct feasibility qualitatively with the guidelines according to the criteria ofthe assessment category. The results of expert validation showed the averagepercentage (a) of material experts was 84% with very feasible categories; (b)media experts 90% with very decent categories; (c) linguists 97% with verydecent categories; (d) colleagues 79.6 categories worth%; (e) practitioners86.4% are very decent categories. The average response of students to productdevelopment results 89.5% with a very feasible category. This shows that themodules developed are feasible to be used at the stage of large-scale trials.

Petroleum has characteristics macroscopic, microscopic, and symbolic. All three of these characteristics are related to each other, so that the students in the learning process was difficult to understand the material of petroleum, which leads to lower interest entrepreneurial students and student learning achievement. This problem can be solved by applying the LTmodel based Entrepreneurship. This study aimed to determine the effect of the application of LT models based entrepreneurship to entrepreneurs interests and student learning achievement. This type of research was quasi-experimental research design pretest-posttest control group design. The sample in this study was 70 students of class X SMAN 7 Mataram where was divided into an experimental group of 36 students and a control group of 34 students. The experimental class were learning by LT models based entrepreneurship and control class were learningby conventional learning models. Instruments used include syllabi, lesson plans, worksheets, implementation sheets of lesson plans, interest entrepreneurship test and learning achievement. Data analysis technique using One-Way ANOVA using SPSS 16.0 for Windows. From the results of this study concluded that: (1) Score average interest entrepreneurial students in the experimental class has risen from 71 to 73 who are at high category, and the average score in the control group were also at the high category, but experience changing interests of entrepreneurs from the average score of 71 to 70. (2) the application of LT models based entrepreneurship effect on student learning achievement. This was evidenced by sig. amounting to 0.036> 0.05.

This study aims to compare student achievement in teaching chemical equilibrium topics using a guided inquiry approach combined with and without flow charts. This research is a quasi-experimental study with a pretest-posttest control group design. The study sample consisted of 31 experimental class students and 24 control class students. The instruments in this study consisted of two types, namely (1) the instrument of treatment in the form of learning devices using a guided inquiry approach combined with flow diagrams in the experimental class students and guided inquiry learning in control class students, while (2) measurement instruments in the form of learning outcomes tests students, student activeness observation sheets, and student performance assessment sheets. The instruments are declared valid by 2 chemistry lecturers and 1 chemistry teacher who has good competence and experience in chemistry and chemistry learning. The results showed that the guided inquiry approach combined with the flow diagram provided students’ cognitive learning achievements (83.87 experimental classes and 70.83 control classes), affective (79.00 experimental classes and 74.00 control classes), and psychomotor (84.00 experimental class and 80.00 control class) were better than guided inquiry approaches without flow diagrams.
