Teaching and learning activities is a conscious activity and aims. Therefore, for these activities can be run well and achieve the expected goals, it must be done with the strategy or the right learning approach .. The purpose of this study were: 1) to describe the influence of Self-Concept on the results of studying chemistry at Class XI MA Pacet Mojokerto. 2) Describe the effect of self-efficacy on Learning outcomes chemistry in Class XI MA Pacet Mojokerto 3) Describe the effect of motivation on Learning outcomes chemistry in Class XI MA Pacet Mojokerto 4) Describe the relationship Self-concept, self-efficacy and motivation to Results studied chemistry at Class XI MA Pacet Mojokerto. From the results of the analysis can be summarized as follows: 1) There is a significant relationship between self-concept of the Learning outcomes chemistry inquiry model. T test against self-concept variables (X1) obtained regression coefficient (B) 0.440 (44.0%), coefficient (Beta) 0.091, tcount of 0.378 with significance 0.006 t. Because of the significance of t less than 5% (0.007 <0.05), the Nil Hypothesis (H0) is rejected and working hypothesis (Hi) is received. 2) There is a significant relationship between self-efficacy toward chemistry Learning outcomes inquiry model. T test for Self-efficacy variable (X2) obtained regression coefficient (B) 0.329 (32.9%), coefficient (Beta) 0.124, tcount of 0.436 with a significance of 0.009 t. Because of the significance of t less than 5% (0.008 <0.05), the Nil Hypothesis (H0) is rejected and working hypothesis (Hi) is received. 3) There is a significant relationship between motivation to learn chemistry results inquiry model. T test for motivation variable (X3) obtained regression coefficient (B) 0.130 (13.0%), coefficient (Beta) 0.065, tcount of 0.230 with a significance of 0.001 t. Because of the significance of t less than 5% (0.001 <0.05), the Nil Hypothesis (H0) is rejected and working hypothesis (Hi) received 4) From the calculation results obtained Fhitung value 2,249 (significance F = 0.001). So Fhitung> F table (2,249> 2:03) or Sig F <5% (0.001 <0.05). It means that together independent variables consisting of variable self-concept (X1), Self-efficacy (X2), motivation (X3) simultaneously to variable results of studying chemistry (Y).

Pemilihan karier merupakan pengambilan keputusan siswa atas dasar pemahaman potensi. Beberapa masalah lulusan sekolah kejuruan saat ini termasuk kurangnya kemampuan pengetahuan (potensi) diri; belum dapat memutuskan rencana setelah lulus, apakah bekerja, kuliah, atau wiraswasta; kekurangan pemahaman jenis pekerjaan; belum mampu menggabungkan potensi pekerjaan yang akan dipilih; dan belum bisa merencanakan kariernya. Penelitian ini bertujuan untuk mengetahui pengaruh efikasi diri, konsep diri, kematangan karir, kematangan vokasional dan orientasi karir siswa SMK dalam pengambilan keputusan karir. Teknik pengambilan sampel yang digunakan adalah probability sampling. Subjek penelitian ini adalah siswa kelas XI dan XII SMK di Sumatera, Jawa Tengah dan Yogyakarta. Teknik analisis data uji regresi berganda untuk mengetahui hubungan antara variabel bebas dan variabel terikat. Hasil penelitian menunjukkan bahwa terdapat pengaruh positif dan signifikan antara efikasi diri karir, konsep diri, kematangan karir, kematangan vokasional dan orientasi karir siswa SMK dalam pengambilan keputusan karir sebesar 20,3%. Berdasarkan penelitian yang telah dilakukan, pilihan karier siswa adalah dampak yang diberikan terhadap wawasan karier. BK dan BKK diharapkan mampu mengoptimalkan pelayanannya terkait mengenai berbagai informasi tentang dunia kerja, jumlah peluang kerja dan  kualifikasi yang dibutuhkan untuk berbagai macam jenis profesi yang ada, sehingga siswa dapat menentukan pilihan karirnya secara mandiri. Career selection is a student's decision-making on the basis of understanding potential. Some of the problems of current vocational school graduates include lack of self-knowledge; not being able to decide after graduation, whether to work, study, or self-employed; lack of understanding of work; not being able to combine potential the job to be chosen; and have not been able to plan their career. The research aims to determine the effect of self-efficacy, self-concept, career maturity, vocational maturity, and career orientation of vocational students in making career decisions. The sampling technique used is probability sampling. The research subjects were students of Vocational High School classes XI and XII in Sumatra, Central Java, and Yogyakarta. The regression test data analysis techniques to determine the correlation between the independent variables and the dependent variable. The results showed that there was a positive and significant influence between career self-efficacy, self-concept, career maturity, vocational maturity, and career orientation of vocational students in career decision-making of 20.3%. Based on the research that has been done, students' career choice is the impact given to career spirit. BK and BKK are expected to be able to optimize their services related to various world information, the number of job opportunities, and qualifications needed for various professions, so that students can make independent choices.

Introduction: The relationship that socio-familial and non-cognitive variables have on students in regards to their academic performance is a very important element for success in Secondary Education. In this study the influence of non-cognitive variables (academic self-concept, self-efficacy and perceived family affective support) and socio-familial variables (educational level and expectations of each parent) on the academic performance of secondary school students were analysed. Method: Students were grouped according to their accumulated socio-familial risk index (at-risk students, n = 305; not-at-risk students, n = 991). To measure the variables, the scales What do you think of yourself, General Self-Efficacy and Perceived Family Support were used. Socio-family variables were measured with an ad hoc questionnaire, and academic performance with the end-of-course evaluation scores. Results: The receiver operating characteristic curve showed a decrease in students’ academic performance from three or more accumulated risks. Structural Equation Modelling (SEM) was performed for each group. The results showed that for at-risk students, academic performance was mainly determined by two variables: academic self-concept and self-concept; in contrast to the not-at-risk students in which self-efficacy was the one that had the greatest effect on performance. In both groups, the parents’ expectations were the family variable with the highest incidence being performance, although, for the at-risk group, the effect was greater. Conclusions: The relevance of the identification of non-cognitive and socio-familial variables on the academic performance of at-risk students in regards to secondary education due to socio-familial factors is discussed.
