Authors: Liu Xiaolan , Wang Baoju , Yao Longfang , Fei Yiyan , Mi Lan , Ma Jiong , Yang Weidong
Published: June 2019

It is often difficult to implement complex microscopy systems without spherical aberration. Herein, we developed a novel, robust, three-dimensional (3D), bifocal plane, single-particle tracking technique, based on a dual-objective fluorescent reflection system with spherical aberration (DOFR–SA). It can simultaneously image a pair of focused and defocused planes containing fluorescent particles with a single camera instead of splitting photons into two channels. Based on the 3D DOFR–SA, the desired position accuracy along the z-axis was achieved without compromising the precisions of the (x, y ) positions, even with limited number of photons from a single molecule. Accordingly, this method was applied to fluorescent particle tracking in biofluids and living cells with high-spatial and temporal precisions.

The aim of this study was to analyze the effect of Project Based Learning (PjBL) model on critical thinking, scientific attitude, and self-efficacy in students. This study used a quasi-experiment of pos-ttest only control group design. The subjects were 60 ninth grade students of public high schools in Singaraja in the academic year 2017/2018 selected randomly from the existing classes, in which 30 students were assigned to the experiment class and another 30 to the control class. The instruments used were critical thinking test, scientific attitude questionnaire, and self-efficacy questionnaire. The instruments had a high reliability. The data were analyzed descriptively and to test the hypothesis, MANOV with the 5% significance level was used. The result showed that simultaneously critical thinking, scientific thinking, scientific attitude, and self-efficacy of the students who learned with PjBL and authentic assessment significantly differed from those who learned with PjBl and conventional assessment (F=10.79; p<0.05). The group of students who learned with PjBL and authentic assessment had a high mean than that of those who learned with PjBL and conventional assessment. In other words, authentic assessment is effective in enhancing critical thinking, scientific attitude, and self-efficacy of the students in science teaching.

The world of education is currently facing new challenges since it enters the industrial revolution era 4.0 in which the digital industry has become a paradigm and reference in the recent order of life. The Industrial Revolution 4.0 comes together with the disruption era of which new literacy incorporating data, technology literacy and human literacy. Data literacy is related to the ability to read, to analyze and to make conclusions based on obtained data and information (big data). Technology literacy emphasizes on the ability to understand the way of the working machine. It also includes technology applications and technology-based work to produce maximum results. Human literacy focuses on communication, collaboration, critical thinking, creative and innovative abilities. In case of human literacy, it is necessary to develop positive characters to equip Indonesian people with Pancasila character. The efforts to produce a generation that can compete in disruption era must be done in some integrated way with Innert-depend strategies to foster a holistic culture and community morality with the potential basis of the community including Pancasila character. This study aims at producing Innert-depend strategies development model through making best practice film of Android based learning of Pancasila characters. The research method was using Research and Development [1] with the 4-D (Four-D Models) modified by R & D form of [2]. Research procedure include Define phase; Design phase; Develop phase and Disseminate phase. The first stage was to produce film packages best practice of Android-based Pancasila character, the second stage was to produce students’ Innert-dependent strategies development model to face disruption era, and the third stage, the model has been disseminated in the student environment through intra-curricular and extracurricular. The results showed that there was an increase in Innert-depend strategies during the experimental class students and the standard gain average in the experimental class was in the "high" category which was significantly different from the control class with "medium" category. Based on these results, it can be concluded that the average innert-depend strategies test results and understanding of the experimental class concept were higher, both from the average score and the standard gain mean.

Published: June 2019

The community empowerment and development attempts in Indonesia border area must be carried out through integrated efforts to foster innertdepend strategies. The potential threat to the national sovereignty should be prioritized although it needs some great efforts. The risk of losing islands along the cross-border areas of country needs to be anticipated better and more professionally. One strategic step to deal with this case is optimizing educational institutions in the cross-border region. It can be realized by utilizing megabiodiversity as a source of natural science learning as well as instilling a national pride of having abundant natural resources in the archipelago. The next strategy is by incorporating innertdepend strategies for the students. The research design of this study is the type of "Prototypal Studies" as put forward by [1] and [2]. The important thing to be considered in the Research and Development model is the quality of the produced learning model (product). [2] provides product quality criteria, namely: valid (reflects state-of-the-art knowledge and internal consistency), added value, practical, and effective. The results of the study are; (1) integrated learning model of natural sciences with the development of innertdepend strategies by utilizing the megabiodiversity that has been tested for its feasibility through expert judgment and limited empirical trials in the partnership schools can be catagorized “Good”, (2) integrated learning model of natural science with innert depend strategies is effective to improve concepts understanding and innert-dependent strategies for students in border area schools.

The objectives of this study were to develop the scale called the student test of scientific literacy integrated character (SToSLiC), to analyze its validity and reliability, and to portray the primary profile of scientific literacy integrated character of junior high school students in Mataram. The scale was developed in four steps include identifying indicators, developing pool items, checking items validity and reliability, and improving items quality. The scale consists of two parts that are the SToSLiC-A and the SToSLiC-B. The primary pool items of the SToSLiC-A consist of 42 multiple choice items, and 40 Likert-scale items for the SToSLiC-B. The scale was administered to 222 eight graders student in Mataram city. Seven items were eliminated from the initial SToSLiC-A because of the item total correlation were < 0.05 or invalid. Based on item total correlation of the 35 remaining items, the SToSLiC-A was classified as valid (item total correlation coefficient > 0.05), and it has good internal consistency (Alpha-Cronbach coefficient of 0,63). All 40 items of the SToSLiC-B were valid (item total correlations > 0.05) with good internal consistency (Alpha-Cronbach coefficient of 0.87). Based on these values, it can be concluded that the SToSLiC developed in this study provide an objective measure of acquisition of scientific literacy and character of junior high school students.
