Science as one of the subject in the 2013 curiculum demands the development of students’ scientific literacy. The measurement of scientific literacy of Indonesian students conducted by PISA (Program for International Student Assessment) is still relatively low. This can be caused by the process and the assessment instruments used today are dominated by low cognitive demands so that they have not been able to develop students’ high level order thingking. This research aims to develop assessment instruments based on scientific literacy of the motion of living things, structure and function of plant tissues for class VIII SMP. This development research using the Plomp model which consists of preliminary research phase, development or prototyping phase, and assessment phase. The subjects were 39 students of class IX SMP Negeri 8 Padang. The results showed that validity was logically stated to be very valid with an average 86.55% and valid according to empirical validity of 76.78%. Based on practicalities are very high with value of 88.75%  from teachear and of 88.94% from students. The reability shows a very high category with 0.81 for multiple choice question and a moderate category of 0.59 for true-false questions. The level of difficulty is varies and has a good distinguishing. Based on this, it can be concluded that assessment instruments based on scientific literacy of the motion of living things, structure and function of plant tissues for class VIII SMP can be declared very valid, very practical, and reliability in the medium to very high categories. Keywords:  scientific literacy, assessment

Aging is a complex, normal, and inevitable process affecting all living things. The physiologic changes of aging, by definition, are postmaturational, occurring after adult maturity is achieved. Changes with aging are primary, irreversible, and progressive. While the processes of aging are neither pathology nor disease, they present important changes in structure and function that alter drug disposition, metabolic rate, and excretion. These changes present special challenges to clinicians in critical care settings for whom pharmacotherapy is a common treatment modality. This article explores the physiologic changes associated with aging and the implications of these changes for management of critically compromised elders. Drug metabolism, distribution, utilization, and excretion in older adults are examined

The lack of availability in assessment instruments used and unmet cognitive levels of C3-C6 resulted in poor quality assessments. This study aims to develop cognitive domain assessment instruments on the concept of heat transfer material in grade V elementary school. This research was development research that used 4D models (Four-D models) to define, design, develop, and disseminate. The subject of study was the assessment instrument of the cognitive realm with the object of research, that was the instrument quality. Measurement of the validity of the content was done on two experts/judges using the non-test method and instruments of the expert validity sheet. Instrument quality measurement was conducted with field trials of 106 students using multiple-choice objective test instruments. The content validity data obtained were analyzed with the Gregory formula, while the field test result data analyzed the validity of the grain, reliability, different power, and difficulty level.  The results showed that the validity of the content obtained by 0.97 (very high) with the test results of the item's validity got 30 points of the question was declared valid. The instrument reliability index was developed by 0.85 (very high). The average coefficient of different power obtained is 0.51 (good) with a test device difficulty of 0.52 (medium). The result demonstrated cognitive domain assessment instruments that were developed feasible and can be used in conducting learning assessments in the cognitive realm.

The 21st century skills focus on scientific literacy competences in various urban and rural areas, one of which is Papua. Scientific literacy has competences to identifying scientific problems, explaining scientific phenomena, and utilizing scientific findings to solve problems. The purpose of this study was to determine the science literacy competences of IPA class VIII students of SMPN 5 Jayapura. Scientific literacy is competencies to understanding science, communicating science, and applying scientific conceptual to solve problems. A descriptive qualitative approach is used as this type of research. This research was conducted at SMPN 5 Jayapura. The sample selection used purposive sampling technique. There were 33 students who became respondents and teste in this study. The research instruments were documentation, observation, tests and interviews. The average percentage of competency aspects with indicators of identifying scientific problems, explaining scientific phenomena, and utilizing scientific findings is below 80%. The average percentage of aspects of knowledge about the concept of motion, with sub-concepts of regular motion, force, and Newton's laws is below 90%. The average percentage of human, animal and plant movement systems is below 70%. The highest score, average, median, mode, and lowest score of the cognitive scores of students' scientific literacy abilities were 100; 68.33; 75; 80; and 30.

Learning styles can make students learn easily, fun, meaningfully that will improve their learning outcomes. This study aimed to determine the correlation between learning styles and student’s learning outcomes in online learning about structure and function of plant. The correlation test method was used and samples were chosen using simple random sampling, consisting of 68 students in class VIII SMPN 2 Pangkalpinang. The data were collected using interview, questionnaire, documentation methods, and analyzed by Pearson product moment correlation test. The results showed that about 72% students in class VIII SMPN 2 Pangkalpinang tended to have a visual learning style and 75% with completed learning-outcomes. The correlation test indicated that there was no significant relationship between learning styles and their learning outcomes, by evidence and determination value of 0.111 more than 0.05 and 3.8% simultaneously. There is no correlation between learning styles and learning outcomes, presumably because learning styles only contribute 3.8% in which other 96.2% were determined by other factors such as teacher motivation and teaching strategies. However, although there is no correlation, learning styles still contribute to student’s learning success. Therefore, it is necessary to conduct further research related to other factors that may affect student learning outcomes.

This study aims to reveal the feasibility, quality, and characteristics of scientific literacy assessment instruments with electrolyte and non-electrolyte solutions, to measure students' scientific literacy skills in electrolyte and non-electrolyte solutions. This study uses the development model of Oriondo and Dallo-Antonio which consists of five stages, namely planning for making assessment instruments, testing instruments, determining empirical validity, determining reliability, and interpreting scores. The initial product of the assessment instrument was validated by two experts, and one chemistry teacher. This research was conducted in three state vocational schools in Lubuklinggau City with a total of 30 students as research subjects. Data collection through developed assessment instruments. The test results of the assessment instrument were analyzed using Rasch's Item Response Theory model with the help of the Winstep 3.73 program. The chemical literacy ability assessment instrument consisting of 25 essay questions was declared feasible and valid with a minimum value of 0.75 and 0.79 on the Aiken index. The results of empirical validation show that 20 items are valid in the analysis of the results of the first trial and there are 17 items as the final product. The final product of the instrument consists of three categories of difficulty, including three items in the difficult category, 12 items in the medium category, and two items in the easy category. The assessment instrument has a high reliability score, namely the Cronbach alpha value of 0.86 in the first trial; 0.92 trial II; and 0.89 in trial III. The profile of students' scientific literacy ability is generally good, in terms of context,
