Sementara keterampilan proses sains antara siswa yang belajar menggunakan model pembelajaran discovery learning dengan siswa yang belajar menggunakan model pembelajaran konvensional pada materi tata surya dengan mempunyai nilai  thitung 2,732 dengan nilai signifikannya 0,008<0,05 dengan nilai dk=N-2-62.                       &nbsp

Perbedaan Keefektifan Model Pembelajaran Kooperatif Tipe STAD (Students Teams Achievement Division) dan Jigsaw Terhadap Kemampuan Pemecahan Masalah pada Pembelajaran Fisika

The purpose of this study is to find out: (1) whether there is an effectiveness of the STAD learning model for solving science problems (Physics); (2) is there an effectiveness of the Jigsaw learning model for problem solving in Natural Sciences (Physics); and (3) whether there is an effectiveness of the STAD and Jigsaw learning models in solving science (Physics) problems. This research is a quantitative study using quasi-experimental design. The research sample consisted of students in class VIIIa and VIIIb of SMP Negeri 2 Ende, while the object of this study was the influence of STAD learning, the influence of Jigsaw learning, and the problem-solving ability of students. Data collection is done through tests and observations. The research instrument consists of objective tests for problem solving skills. Data analysis using one sample test and different test. The results showed that the problem-solving ability of students at SMPN 2 Ende experienced differences between the three learning above. Can be seen in the total difference in the STAD method of 7552,000; for the Jigsaw 8438,000 method; and for the conventional model of 4405,000. This proves that the Jigsaw type cooperative model is more effective than the STAD type cooperative model and conventional learning model, while the STAD type cooperative model is more effective than conventional.The purpose of this study is to find out: (1) whether there is an effectiveness of the STAD learning model for solving science problems (Physics); (2) is there an effectiveness of the Jigsaw learning model for problem solving in Natural Sciences (Physics); and (3) whether there is an effectiveness of the STAD and Jigsaw learning models in solving science (Physics) problems.

Prevalence of postdural puncture headache among caesarean section patients in North Central Nigeria

Spinal anaesthesia is now a popular choice for Caesarean sections in Africa but one of the draw-back is the development of post-dural puncture headache (PDPH) and it could be quite distressing to a mother. Identifying risk factors and reducing the prevalence is pertinent. This study sought to determine the prevalence of PDPH among patients who underwent Caesarean sections in a tertiary hospital in Jos, Plateau State, Nigeria and some of its possible associated factors. Method: It was a prospective study of all Caesarean sections done under spinal anaesthesia between November 2016 and June 2017. Spinal anaesthesia was performed on 236 parturients using Quincke-type needles sizes 23-26G. In the postoperative period, all the patients were followed-up to determine the incidence, onset, and severity of post-dural puncture headache. Epi-info version 7 was used for data analysis. Results: The prevalence of PDPH was 22.03%. Most of the parturients who developed PDPH in our study were of mild to moderate intensity using the numeric rating scale. Twenty six (11%) had mild, while 11 (4.7%) had moderate intensity of headache and which was resolved with treatment. Conclusion: The prevalence of PDPH is high in the obstetric population especially with the use of traumatic Quincke-type needles. Deliberate efforts must be made to reduce its occurrence by acquiring of small calibre pencil-point needles and training staff on how to use it
