The Impact of Guided Discovery Learning on the Performance of Grade 11 Learners in Identification of Ions

This study explored the impact of guided discovery learning on the performance of grade 11 learners in the identification of ions. Fifty eight grade 11 learners of Matete Secondary School, a public school in Kitwe district of Zambia were involved in the study. The research design used was a Quasi-Experimental counter balance. Chemistry achievement test (Pre-test and Post-test) and a Likert scale questionnaire were used to collect data. The experimental group was taught using guided discovery method while the control group was taught using the conventional (discussion) method. Results from the chemistry achievement test revealed gain for both groups. In the first cycle the guided discovery group had a pre-test mean of 23 which increased to 59 in posttest1. The conventional group had a pre-test mean of 19 which increased to 45 in posttest1. The group means of the conventional and guided discovery groups were compared using student t-test at α= 0.05 and were found to be significantly different. This implied that there was a significant difference between the two teaching methods. Both groups showed an increase in the mean but the discovery group showed a greater improvement than the conventional group. The second cycle involved swapping of the two groups and it was found that the discovery group showed a higher mean performance of 61 than the conventional group which had a mean performance of 49. The p-value was found to be 0.029. Results from posttest2 showed a significant difference between guided discovery learning and conventional (discussion) learning.  Attitudes towards guided discovery learning on the identification of ions were obtained through a five point Likert scale questionnaire and generally, learners showed positive attitudes towards the guided discovery teaching method. It was concluded that guided discovery learning improved learner performance on chemistry concepts (identification of ions) and learners showed positive attitudes towards the teaching methods as suggested by the measure of central tendency.

PERANAN PENYIDIK KEPOLISIAN RESOR MUARA ENIM DALAM PENEGAKAN HUKUM TERHADAP TINDAK PIDANA PEMERKOSAAN ANAK KANDUNG

ABSTRAK   Latar belakang dalam penelitian ini adalah Kasus yang menyita perhatian publik yaitu kasus kekerasan, pencabulan, pemerkosaan terhadap anak kandung yang dilakukan oleh ayah kandunya sendiri  di Polres Muara Enim. Rumusan masalah dalam penelitian ini adalah 1) Bagaimanakah  peranan penyidik Kepolisian Resor Muara Enim terhadap tindak pidana pemerkosaan anak kandung? Dan 2) Apakah kendala yang dihadapi penyidik Kepolisian Resor Muara Enim dalam menangani tindak pidana pemerkosaan anak kandung?. Metode penelitian yang digunakan adalah penelitian empiris. Sumber data yang digunakan dalam penelitian ini terdiri dari data primer dan data sekunder. Berdasarkan hasil penelitian menunjukkan bahwa Peranan penyidik Kepolisian Resor Muara Enim terhadap tindak pidana pemerkosaan anak kandung telah cukup maksimal, meskipun belum begitu komprehensif sesuai dengan teori peranan normatif dan faktual dan sejalan dengan teori pemidanaan absolut dimana peran normatif dilaksanakan beradasarkan Undang-Undang Kepolisian, sedangkan peran faktual yang dilaksanakan oleh penyidik Kepolisian Resor Muara Enim terhadap tindak pidana pemerkosaan anak kandung, diantaranya yaitu tindakan pre-emtif (antisipasi), tindakan preventif (nonpenal) dan tindakan represif. dan 2) Kendala yang dihadapi penyidik Kepolisian Resor Muara Enim dalam menangani tindak pidana pemerkosaan anak kandung meliputi 1) faktor hukum, 2) faktor penegak hukum yakni minimnya sumber daya manusia penyidik, 3) faktor sarana dan prasarana  meliputi Kendala dalam pendanaan (keuangan), 4) faktor masyarakat meliputi Tingkat Kesadaran Hukum masyarakat yang masih sangat rendah; Rendahnya partisipasi dari masyarakat untuk sama-sama melakukan pengawasan terhadap anak-anak dibawah umur; saksi susah untuk di mintai keterangan; dan pelaku melarikan diri.  Kata Kunci:   peranan, penyidik, tindak pidana pemerkosaa

Molecular characterization and distribution of Schistosoma cercariae collected from naturally infected bulinid snails in northern and central Côte d’Ivoire

Accurate identification of schistosome species infecting intermediate host snails is important for understanding parasite transmission, schistosomiasis control and elimination. Cercariae emerging from infected snails cannot be precisely identified morphologically to the species level. We used molecular tools to clarify the distribution of the Schistosoma haematobium group species infecting bulinid snails in a large part of Côte d’Ivoire and confirmed the presence of interspecific hybrid schistosomes. Methods Between June 2016 and March 2017, Bulinus snails were sampled in 164 human-water contact sites from 22 villages of the northern and central parts of Côte d’Ivoire. Multi-locus genetic analysis (mitochondrial cox1 and nuclear ITS) was performed on individual schistosome cercariae shed from snails, in the morning and in the afternoon, for species and hybrid identification. Results Overall, 1923 Bulinus truncatus, 255 Bulinus globosus and 1424 Bulinus forskalii were obtained. Among 2417 Bulinus screened, 25 specimens (18 B. truncatus and seven B. globosus) shed schistosomes, with up to 14% infection prevalence per site and time point. Globally, infection rates per time point ranged between 0.6 and 4%. Schistosoma bovis, S. haematobium and S. bovis × S. haematobium hybrids infected 0.5%, 0.2% and 0.4% of the snails screened, respectively. Schistosoma bovis and hybrids were more prevalent in B. truncatus, whereas S. haematobium and hybrid infections were more prevalent in B. globosus. Schistosoma bovis-infected Bulinus were predominantly found in northern sites, while S. haematobium and hybrid infected snails were mainly found in central parts of Côte d’Ivoire. Conclusions The data highlight the necessity of using molecular tools to identify and understand which schistosome species are transmitted by specific intermediate host snails. The study deepens our understanding of the epidemiology and transmission dynamics of S. haematobium and S. bovis in Côte d’Ivoire and provides the first conclusive evidence for the transmission of S. haematobium × S. bovis hybrids in this West African country.
