Validity of Student Work Sheet Based Guided Inquiry on Learning Materials of Organism Classification and Life Organization for MTs Students Grade VII
No full textCurriculum is an educational response to societies’ and nations’ needs in developing young generation. The curriculum gives a significant contribution to bring the development process of students’ potential in learning into reality. Learning of Science (IPA) emphasizes on the ability to do scientific inquiry to raise cognitive, affective, and communicative skills. IPA includes four main elements: attitude, process, product, and application. IPA learning process is expected to raise those four elements so that students can experience the whole learning process, and it can be used to solve life’s problems. It can be reached by applying one learning model, that is ‘guided inquiry learning model’. The learning process cannot also apart from learning materials. One of the materials is student work sheet, which is able to improve students’ skill process. The aim of the research was to develop student work sheet based guided inquiry for MTs students grade VII and to validate its criteria. The research was a development research using Plomp model. The Validity of student work sheet based guided inquiry was obtained from the result of expert validity sheets done by four experts. The result of this research showed that in didactic aspect got 77,08% with the criteria was valid, construct aspect got 90% with very valid criteria, technical aspect got 85,93% with the criteria was very valid, and the average of these three aspects got 84,33% with the criteria was very valid. Student work sheet based guided inquiry was successful to be developed by validity criteria, which was very valid. Then, it is expected that it can be a qualified and innovative learning material to help improve students’ learning competence
Detection of p53 germline mutation in Li-Fraumeni syndrome families
No full textLi-Fraumeni syndrome is an autosomal dominant familial cancer syndrome that in its classic form is defined by the existence of both a proband with a sarcoma and two other first-degree relatives with a cancer by age 45 years. Approximately 70% of families with LFS is caused by p53 gene mutation. P53 mutant could not do its normal function to arrest at G1 phase of cell cycles or to induce the cell death program via apoptosis after DNA damage and thereby may attempt replication of damaged genome. This activity suggests that cells with mutant p53 will accumulate further mutations more rapidly and display increases genomic instability. This condition is consistent with the increased neoplastic potential of patients with Li-Fraumeni syndrome who inherit a germ line defect in one p53 allele.Sequencing technique is a rapid detection procedure has been developed to detect the p53 germ line mutation in Li-Fraumeni syndrome family, but because it is so labor intensive, large-scale screening tests are impractical. Some alternative techniques have been developed like functional screening test of p53 mutation based on the loss of wild type transcription activation and single strand conformation polymorphism mutation analysis based on the differences of single strand DNA migration pattern on polyacrylamide gel
