Abstract

Students commonly judge that cell metabolism topic is arduous since they only listen to their teacher and memorizing concept without a deep comprehension. Other than that, a direct explanation could not enhance the students’ science process skills. Thus, this research intended to analyze the differences of the content-analysis and science process skills between the students experiencing a learning that oriented to scientific independence (experimental class) and those joining a direct learning (control class). The materials taught in both classes were cell metabolism. This study employed the quantitative of the quasi-experimental method. The research object was the students learning Biology. The students joining a scientific independence-based class were able to answer questions requiring analytical thinking. The relationship of the students’ scientific independence towards the content analysis and science process skills was seen on the test. Based upon the statistical data analysis, the correlation significance was 0,038<0,05. Therefore, it concluded that there was a very significant correlation between the students’ scientific independence towards the content analysis and science process skills.

Most all of earth and space science concepts are unobservable and require reasoning. Unobservable concepts have made prospective physics teachers found it hard to understand the concepts correctly. It needs visualization to help understand the concepts easily. The aim of this study was to enhance the mastery concept of earth science topic especially the earth atmosphere using interactive conceptual with visualizations and authentic data analysis with GrADS (Grid Analysis Display System). There were 23 prospective physics teachers in Bengkulu, Indonesia participated in this study. A convenience sampling technique was employed in this study. This study used pre-experimental, one group pretest-posttest design. The data were collected using pretest and posttest, questionnaires, and observation sheets. The pretest and posttest were analyzed quantitatively, while the questionnaires were analyzed qualitatively. The results showed that the prospective physics teachers’ concept mastery improved from no mastery to compete with the average normalized gain of 0.64 (medium category). 30.44% of the prospective physics teachers obtained the N-gain score in the high category and 69.56% obtained the N-gain score in the moderate category. This compilation gave them experience about the real condition of solar radiation in Indonesian atmosphere during their learning activity. It concluded that the earth science learning using interactive conceptual instruction supported by visualization and GrADS could enhance the students’ concept mastery.

Abstract

The purpose of this study was to develop a curriculum model which included local primacy based on the principles of social reconstruction curriculum in West Nusa Tenggara. This study was a developmental research which adopted and modified Borg & Gall developmental model (1983) with the following stages: (1) needs analysis; (2) model development; and (3) model validation. The results of needs analysis indicated that coral reef materials were the main priority of local primacy integrated into the secondary school curriculum in West Nusa Tenggara. The principles of social reconstruction curriculum were implemented in three components as the result of model design, i.e. learning objectives, learning methods (organizational learning strategies, learning delivery strategies, and learning management strategies), and learning results or assessment. The product design model was embraced in instructional tools consisting of syllabus, topic formulation and basic competence, comic learning materials, and assessment instruments. Based on the assessment qualifications on the instructional tools validation test which included three aspects, namely the content aspect, the display aspect and the accuracy aspect of language use, the mean scores were 3.4, 3.8, and 3.4 respectively. Therefore, the overall instructional tools were in a very good category.

Abstract

Metallothionein (MTs) is a protein that binds to metals, cysteine-rich and has low molecular weights. Metallothionein binds metals and has some essential cellular functions, such as transportation, storage, and metal detoxification. When metallic lead (Pb) and cadmium (Cd) are absorbed, it will immediately be bounded by metallothionein and transported by the blood to the liver. Metallothionein gene is encoded by MTs. This study aimed to identify the MTs gene in blood of fuel station workers which can further be used as a biomarker of the vulnerability of the body as a result of exposure to heavy metals like Pb and Cd in humans. This study was a cross-sectional study, conducted for 8 months and took place in Fuel Stations in the city of Semarang. Samples were fuel station workers who met the study criteria, they sought to fulfill as much as 52 samples. Blood of samples was taken approximately 5 ml and then the MT2 gene was analyzed using Polymerase Chain Reaction (PCR). The data were analyzed descriptively. The results showed that 96% of MT2 gene expression had a resemblance to normal human gene sequences by Blast GenBank. MT2 gene expression does not always reflect the accumulation of lead and cadmium in the blood of fuel station workers. The MT2 gene is likely to have a limitation when used as a biomarker for early detection of the heavy metals exposure in humans to determine the susceptibility of heavy metals exposure.
