This study aims to describe whether there are differences in learning mathematics-based problem-solving in terms of results and student motivation of mathematics. This type of research is a quasi-experimental research and the design carried out on this study is a pretest-postest nonequivalent group design. In this research, the observation was done twice, before and after treatment. Observations made earlier are called pre-test and later observations are called post-test. The result of the calculation of the implementation of mathematics learning with the problem-solving based approach to student achievement is significant (p = 0,000 <0.05). It showed a Fcount of 1.002 <Ftabel of 1.76 with a significance level of 5%. Thus H0 is accepted and Ha is rejected, meaning there is a significant difference in mathematics learning achievement between problem-solving approach and conventional. The result of the calculation of the implementation of mathematics learning with the problem-solving-based approach to student's learning motivation is significant (p-count = 0.03 <0.05) or refer to Fcount of 1.07 <Ftable of 1.76 with a significance level of 5%. So that Ho accepted, it means there are differences in student learning motivation that is taught between using problem-solving based learning and conventional learning. Learning with problem-solving approaches will be effective if the teacher as an educator prepares the problems according to the context. From the results of this study, the researchers recommend being used as a reference for similar research with different subject materials. This research can be developed by adding other attribute variables such as student self-confidence, verbal ability, motivation, nor critical thinking ability.

AIMS: To verify the effectiveness of the simulation in the self-confidence of nursing students for extra-hospital cardiopulmonary resuscitation. METHODS: A quasi-experimental, before and after, single-group study, was performed with nursing undergraduate students. The sample was recruited among university students who were in the second or third year of graduation and accepted to participate in the research. The intervention protocol consisted of individual participation in a emergency simulated clinical scenario. The simulated scenario adopted consisted of cardiopulmonary resuscitation in extra-hospital cardiorespiratory arrest, using the Mini Anne Plus® low fidelity manikin. In addition to the sociodemographic variables, students' self-confidence for emergency action was analyzed, evaluated by the Self-Confidence Scale, before and after each simulation. Marginal and homogeneous Wilcoxon homogeneity tests were applied, and the accepted significance level was 5%.RESULTS: Thirteen two undergraduate students in nursing between the ages of 18 and 38 participated in the study. Statistically significant differences (p < 0.001) were observed in the answers of all the questions of the Self-confidence Scale when compared before and after the simulation. There was also a statistically significant increase (p < 0.001) in cardiological, respiratory and neurological scores after simulation.CONCLUSIONS: The simulation proved to be an effective educational strategy in increasing the self-confidence of nursing students to perform extra-hospital cardiopulmonary resuscitation.

The package C equality education has the distinctiveness of entrepreneurship skills that are put in the functional skills subjects. During this time, the selection of the vocational types (skills) is determined  by the package C manager and without the certificate of competence even though the vocational types can be determined based on the student’s interests through the Rothwell Miller Interest Blank (RMIB) test. After completing the competency tests, the graduate students can obtain the competency certificates from the Competence Certification Institutiton (LSK). This study aims to investigate (1) the students’ interest in vocational learning and (2) vocational learning outcomes in package C’s functional skills subjects. The research was conducted to the 26 research subjects of the 6th level of 2nd advanced competency degree in four PKBM at North Sumatra from August to October 2017. In order to seek out the field validation, the quasi experimental design method with pretest and post-test was used. The data collection instrumentswere in the form of tests with 15 items of multiple choice questions. The program significance was tested with the correlated t-test. The finding showed that the value of the t > ttable was (7.01> 2.06). Therefore, it could be concluded that there was a significant difference in values obtained by the students from before and after participating in sewing learning at a 5% significance level. Thus, in determining the vocational interest, the students should pay attention to the availability of the competency test places.    References Badan Pengembangan Sumber Daya Manusia Pendidikan dan Kebudayaan dan Penjaminan Mutu Pendidikan.(2013).
