Model Pembelajaran Konflik Kognitif Untuk Mengatasi Miskonsepsi Pada Mahasiswa Tadris Fisika Program Kualifikasi S.1 Guru Madrasah

Salah satu faktor umum penyebab rendahnya hasil belajar Fisika yang dicapai siswa adalah terjadinya kesalah- an konsep (miskonsepsi) pada diri siswa. Prakonsepsi atau prior knowladge siswa atas konsep Fisika yang dibangun oleh siswa itu sendiri melalui belajar informal dalam upaya memberikan makna atas pengalaman meraka sehari-hari mempunyai peran yang sangat besar dalam pembentukan konsepsi ilmiah.Miskonsepsi atau salah konsep menunjuk pada suatu konsep yang tidak sesuai dengan pengertian ilmiah atau pengertian yang diterima para pakar dalam bidang itu. Miskonsepsi banyak terjadi pada Fisika khususnya bidang Mekanika. Hal ini pula yang terjadi pada mahasiswa Tad- ris Fisika program Kualifikasi S.1 Guru Madrasah.Untuk mengatasi miskonsepsi mahasiswa tersebut, salah satu model pembelajaran yang dapat diterapkan adalah Model Pembelajaran Konflik Kognitif, yakni model pembelajaran di mana mahasiswa dihadapkan pada per- tentangan antara prakonsepsi yang telah dimiliki dengan konsep ilmiah yang sebenarnya, sehingga mahasiswa akan menyadari kekeliruannya dan mengubah atau melengkapi konsep yang dipahaminya. Model ini terdiri atas tiga fase: (1) mengidentifikasi miskonsepsi beserta latar penyebab- nya;(2) mengonfrontasikan gagasan mahasiswa (prakon- sepsi) dengan konsepsi ilmiah, dalam upaya menggoyah- kan miskonsepsi mahasiswa dan agar mahasiswa menjadi ragu terhadap kebenaran prakonsepsinya; (3) fase konflik, di mana mahasiswa menjadi mengerti dan mau mereor- ganisasi serta merestrukturisasi gagasannya yang megala- mi miskonsepsi

Pengaruh Hubungan Berkelanjutan Terhadap Kesetiaan Nasabah Di BMT NU Cabang Pragaan Kabupaten Sumenep

One strategy for customers to survive and be even more loyal is to provide attractive product offerings, but that is not enough to get customers to survive and need other steps to retain customers, so that today there are many banks and non-bank financial institutions Which apply the concept of long-term relationship with customers. BMT NU Branch Pragaan Sumenep regency as a non-bank financial institutions that form a cooperative to build a sustainable relationship with customers, so it needs to be examined how the loyalty of its customers. The formulation of the problem in this study is whether the continuous relationship affects customer loyalty in BMT NU Branch Pragaan Sumenep regency? How big is the influence of ongoing relationship to customer loyalty in BMT NU Branch Pragaan Sumenep regency?. The purpose of this research is to know the influence of continuous relationship to customer loyalty in BMT NU Pragaan Branch of Sumenep regency, secondly to know how big influence continuous relationship to customer loyalty in BMT NU Branch Pragaan Sumenep Regency. This study uses a quantitative approach with the type of causal research and tools used simple linear regression analysis. The data used are primary data obtained through questionnaire. And Respondents are customers of BMT NU Branch Pragaan Sumenep with a population of 5005 customers and as many samples 98 customers with error rate of 10%. The results showed that there is a significant influence on the ongoing relationship to customer loyalty in BMT NU Branch Pragaan Sumenep. It is stated based on the result of Test-t yield correlation coefficient value tarithmetic= 14.325> ttable=1.290 with a significance level of 0.000 <0.1, and the value of positive beta coefficient. Of the coefficient of determination (R2) by using SPSS (Statistical for the Social Sciences) version 18, By looking at R square gain of 0.681. This means that 68.1% of customer loyalty is influenced by continuous relationships in BMT NU Branch Pragaan Sumenep. While the rest of 39.1% can be influenced by other factors. From the simple linear regression equation (Y = a+ bX) is Ŷ = 2.030 + 0.396X, where the constant value (a) of 2.030 indicates that if the continuous relationship variable is equal to zero (not taken into account), the customer's loyalty is 2.030 units and b = 0.396, it can be interpreted that the magnitude of customer loyalty variable coefficient marked positive (0,396) indicate that if continuous relationship increases 1%, hence loyalty score of customer will increase equal to 39,6%

Strategi Pengembangan Science Generic Skills (Sgs) Calon Guru Fisika Melalui Model Pembelajaran Group Investigation Pada Mata Kuliah Praktikum

Beberapa hasil penelitian menunjukkan masih renda- hnya keterampilan generik lulusan perguruan tinggi, sep- erti keterampilan berkomunikasi, bekerjasama, motivasi, inisiatif, kreativitas, dan kemampuan berpikir logis, siste- matis dan komprehensif. Kondisi ini ternyata juga terjadi di LPTK yang notabene sebagai produsen guru.Dalam tulisan ini akan dipaparkan bagaimana strategi pengembangan Science Generic Skills mahasiswa melalui Model Pembelajaran Group Investigation pada mata kuliah praktikum.Sebagai sebuah model pembelajaran kooperatif, pener- apan Group Investigation pada mata kuliah praktikum dapat menjadi alternatif dalam mengembangkan Keterampilan Generik Sains calon guru. Adapun strategi penerapannya dapat dilakukan dengan melibatkan mahasiswa sejak per- encanaan, pelaksanaan, hingga evaluasi praktikum me- lalui tahap-tahap dalam model Group Investigation, yang meliputi: 1) mengidentifikasi topik dan membagi siswa ke dalam kelompok, 2) merencanakan tugas, 3) membuat penyelidikan, 4) mempersiapkan tugas akhir (analisis dan sintesis), 5) mempresentasikan tugas akhir, dan 6) evaluasi

Retention of uninfected red blood cells causing congestive splenomegaly is the major mechanism of anemia in malaria

Splenomegaly frequently occurs in patients with Plasmodium falciparum (Pf) or P. vivax (Pv) malarial anemia, but mechanisms underlying this co-occurrence are unclear. In malaria-endemic Papua, Indonesia, we prospectively analyzed red blood cell (RBC) concentrations in the spleen and spleen-mimetic retention in 37 subjects splenectomized for trauma or hyperreactive splenomegaly, most of whom were infected with Plasmodium. Splenomegaly (median 357 g [range: 80-1918 g]) was correlated positively with the proportion of red-pulp on histological sections (median 88.1% [range: 74%-99.4%]; r = .59, p = .0003) and correlated negatively with the proportion of white-pulp (median 8.3% [range: 0.4%-22.9%]; r = -.50, p = .002). The number of RBC per microscopic field (>95% uninfected) was correlated positively with spleen weight in both Pf-infected (r = .73; p = .017) and Pv-infected spleens (r = .94; p = .006). The median estimated proportion of total-body RBCs retained in Pf-infected spleens was 8.2% (range: 1.0%-33.6%), significantly higher than in Pv-infected (2.6% [range: 0.6%-23.8%]; p = .015) and PCR-negative subjects (2.5% [range: 1.0%-3.3%]; p = .006). Retained RBCs accounted for over half of circulating RBC loss seen in Pf infections. The proportion of total-body RBC retained in Pf- and Pv-infected spleens correlated negatively with hemoglobin concentrations (r = -.56, p = .0003), hematocrit (r = -.58, p = .0002), and circulating RBC counts (r = -.56, p = .0003). Splenic CD71-positive reticulocyte concentrations correlated with spleen weight in Pf (r = 1.0; p = .003). Retention rates of peripheral and splenic RBCs were correlated negatively with circulating RBC counts (r = -.69, p = .07 and r = -.83, p = .008, respectively). In conclusion, retention of mostly uninfected RBC in the spleen, leading to marked congestion of the red-pulp, was associated with splenomegaly and is the major mechanism of anemia in subjects infected with Plasmodium, particularly Pf
