The purpose of this study is to determine the effects of selected instructional strategies such as Interactive Science Notebook (ISN) Method and Project-Based Learning (PBL) Method and the proficiency (Developing, Approaching Proficiency, Proficient and Advanced) level on the achievement scores of Grade 10 students in Polymer Unit Lesson of Organic Chemistry. This quasi-experimental research based on a 3 × 4 factorial research design involved 125 students. The objectives of the study were (a) analyze the effect of instructional strategies on student achievement scores (b) determine the interaction effect of instructional strategies and proficiency level on achievement scores of students and (c) determine what instructional strategy works best for each proficiency level. Researcher’s developed achievement test was used as pretest and posttest. During the 3-week treatment, experimental groups were exposed to constructivism based learning strategies. After concept development, students were asked to create an infomercial poster and video based on their lesson. Data on gain achievement scores were analyzed through one-way and two-way ANOVA. Results shows that experimental groups performed significantly better than the control group (Lecture Method). It also showed that for students in the Developing and Approaching Proficiency levels they perform better in the ISN and PBL methods, for Advance level students increased their achievement scores by using ISN method. However, Proficient students increased their scores whatever instructional strategies was used on them. It is therefore recommended that collaborative type of instructional strategies should be used in secondary school Organic Chemistry classes. © 2015 American Scientific Publishers. Source

The solvent dependence of several properties of (2,2,6,6-Tetramethylpiperidine-1-yl)oxyl (TEMPO) is investigated by the reference interaction site model self-consistent field (RISM-SCF) theory. Time-dependent density functional theory (TDDFT) coupled with RISM-SCF-SEDD (spatial electron density distribution) is used to evaluate the n → π* transition energies and the results are compared to the reported experimental values. © 2011 Springer-Verlag.

Mt. Malindang is one of the upland ranges where biodiversity has been severely threatened due to forest loss. Fieldwork was conducted from October 2003 to December 2004 in 14 sampling sites from an elevation of 120 to over 1,700 m above sea level to assess the distribution of endemic and threatened herpetofaunal species. Twenty-six species of amphibians and 33 species of reptiles were observed for all sampling sites. The level of endemism for amphibians was 42% where 7 of the 11 recorded species are found only in Mindanao. Nine species were in the threatened category, 8 vulnerable and 1 endangered. For the reptiles, 48% endemicity was observed. No threatened species was found. Field observations show that the major threat to the herpetofauna is habitat destruction, particularly the conversion of the forest to agricultural farms by the local people. It was also observed that endemic and threatened species were distributed in high elevation sites (submontane, dipterocarp, almaciga, and montane forests). Despite habitat loss in Mt. Malindang, 18% of the recorded herpetofaunal species recorded in the Philippines were found in Mt. Malindang, indicating the conservation importance of this mountain range. © Springer Science+Business Media B.V. 2009. Source

In this study, we attempted to quantify indicators of novice programmer progress in the task of writing programs, and we evaluated the use of these indicators for identifying academically at-risk students. Over the course of nine weeks, students completed five different graded programming exercises in a computer lab. Using an instrumented version of BlueJ, an integrated development environment for Java, we collected novice compilations and explored the errors novices encountered, the locations of these errors, and the frequency with which novices compiled their programs. We identified which frequently encountered errors and which compilation behaviors were characteristic of at-risk students. Based on these findings, we developed linear regression models that allowed prediction of students' scores on a midterm exam. However, the models derived could not accurately predict the at-risk students. Although our goal of identifying at-risk students was not attained, we have gained insights regarding the compilation behavior of our students, which may help us identify students who are in need of intervention. © 2011 ACM.

The Fischer indole synthesis was carried out using microwaves instead of conventional heating procedures. When the mixture of phenylhydrazine, cyclohexanone and zinc chloride was irradiated at 600 W for 3 min, 76% of 1,2,3,4-tetrahydrocarbazole was obtained. However, when zinc chloride was replaced with p-toluenesulfonic acid (p-TSA), the reaction yielded 91% of 1,2,3,4-tetrahydrocarbazole. Thus, a series of indoles were prepared using microwaves in the presence of p-TSA catalyst. © 2011 HeteroCorporation. Source
