Penerapan Strategi Pembelajaran Inkuiri Dipadukan Media Audio Visual Untuk Meningkatkan Kualitas Pembelajaran Biologi Siswa Kelas VII D SMP N 1 Jaten

– The aim of this research is improve quality of biology learning for conditioning class, student attitude in class, the performance of teacher and student motivation of learning in student class VII-D 1st Junior High School Of Jaten through the application of strategies for inquiry learning combined audio visual media. This research was classroom action research with planning, action, observation, and reflection steps. Data was collected using questionnaire, observation, and interview. The validation of data using method and observer triangulation techniques. The data analyzed by descriptive. The result in cycles I describes that mean of observation data in conditioning class indicators are 70,20%, students\u27 attitudes in class are 62,77%, performance of teachers in the learning are 80% and students motivation in learning are 68,18%. For the questionnaire, observation data in conditioning class indicators are 74,53%, students\u27 attitudes in class are 74,13%, and students motivation in learning are 74,38%. The result in cycles II describes that mean of observation data in conditioning class indicators are 80,81%, students\u27 attitudes in class are 80.09%, performance of teachers in the learning are 96,67% and student motivation in learning are 83,71%. For the questionnaire, observation data in conditioning class indicators are 83,87%, students\u27 attitudes in class are 82,49%, and students motivation in learning are 79,43%. In addition, this research also uses interview to know effect of research in quality of biology learning. The result of interview shows that students\u27 attitudes more positive, students motivation more increase and classroom climate more conducive on learning activities. The conclusion of research describes that the combination of audio visual media in inquiry learning strategies can improve quality of biology learning for conditioning class, students\u27 attitudes, performance of teachers in the learning and motivation of learning in student class VII-D in 1st junior high school of jaten

Color coding scheme used in the BAPS populations and the NJ trees.

<p>For example, the first row shows the BAPS populations highlighted in the first NJ tree in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000455#pcbi-1000455-g009" target="_blank">Figure 9</a>.</p

Bootstrap mixture analyses of the <i>Neisseria</i> data.

<p>The figure shows the adjusted rand index between the partition based on the original data and the alternative based on a bootstrap data set by resampling in clusters. Five repetitions were made for each of the clusters.</p

Testing partition accuracy for different choices of gene flow weights for a small population size (upper panel) and a large population size (lower panel).

<p>The number of segregating sites for both settings is and the ratio of mutations at two stages is . Data were generated by assigning and randomly at the interval [0,1] with the gene flow topology fixed as in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000455#pcbi-1000455-g002" target="_blank">Figure 2</a>. A brighter area corresponds to a range of and , within which the true partition has been identified by BAPS with a higher accuracy as measured by Rand Index (RI).</p

The number of strains that are jointly assigned into a BAPS population and a EBURST group.

<p>Only the EBURST groups that contain more than 20 strains are listed.</p

Gene flow network identified in the <i>N. meningitidis</i> and <i>N. lactamica</i> populations.

<p>To investigate the ancestral admixture of a certain population, one can look at all the arrows pointing at this population. A typical population contains the major sources of its own, denoted as a self-looping arrows, and small proportions of gene flow from other populations. For instance, population 29 has 73% of its own genetic makeup and 27% of the DNA introduced via gene flow from other populations. Two major sources of gene flow for population 29 are population 19 and population 11, with 3.3% and 6.9% in the contribution separately. The remaining 17.1% of genes comes from various sources while none of them contributes a proportion larger than 3% and therefore are not displayed due to the pruning.</p

Tentative gene flow graph in six populations.

<p>The graph topology can be succinctly termed as , where the node set and the arrow set . The actual rates of admixture associated with the arrows were randomly generated from a uniform distribution. Note the two ways of gene flow between population 2 and 3.</p
