This study aims to see an increase in students’ ability to understand concepts after applying the TTW (Think-Talk-Write) learning model assisted by Pictorial Riddle-based Student Worksheet. The research method used is quasi-experimental. There were two experimental classes, namely the modeling class and the implementation class. The sample of this study was 24 students of class XI Science 4 as modeling class and 23 students of class XI Science 3 as implementation class in Prambanan High School 1 Yogyakarta. Data collection techniques were carried out by Pretest and Post-Test. Data were analysed using the Wilcoxon test and descriptive analysis to determine the N-Gain score. The results showed that the TTW (Think-Talk-Write) learning model assisted by Pictorial Riddle-based Student Worksheet could improve students’ conceptual understanding abilities. This is indicated by the value of Asymp Sig. (2-tailed) smaller than 0.05 where 0.046 < 0.05 and the N-Gain score is 0.2061 in modeling class and Asymp Sig. (2-tailed) smaller than 0.05 where 0.003 < 0.05 and the N-Gain score is 0.2775 in implementation class. The conclusion is this model has an effect on the students’ ability to understand concepts with a low increase category.

The development of Science and Technology in the 21st century progress in various aspects of life. Critical thinking skills are kind of the skills that must be possessed by students as a graduate competency standard. However, this skill is rarely assessed, as there are not many technological instruments to measure the skill. This research was conducted to develop critical thinking skills test instruments in the form of computer-based test (PhysTeCTS-CBT) with Define, Design, Development, and Dissemination (4D) as the method involving three experts. The feasibility of PhysTeCTS-CBT assessed by expert judgment in media feasibility categories. The results of the media validation by three experts indicate that the PhysTeCTS-CBT can be stated valid and has good categories.

This research is a preliminary study conducted to know and measure how student’s environmental literacy attitudes about local wisdom from the local area, namely Java area through the myth of Ficus sp. in adiwiyata school. Data collection techniques and instruments: a closed questionnaire. Questionnaires were then analyzed with SPSS to determine the validity that can be demonstrated by using correlation coefficient. in this study, correlation was calculated with Pearson‘s correlation for data were assumed to be normally distributed. Validity of each indicator was determined from the significance of its correlation with the sum score (item-total correlation). Reliability test: Cronbach’s Alpha formula. Next, the data processing uses descriptive statistical analysis for likert scale data processing. The results showed a percentage of 78.7% which means it is in the good category, but only slightly above the medium category. This indicates that student’s environmental literacy attitudes must continue to be improved.

Published: January 2020

Various researches have showed that people nowadays are not able to identify and classify plants – a problem that derived from the lack of motivation to learn it and the difficulties in understanding it. The objective of this study is to propose a solution to help students more motivated, learn better and easier in order to classify plants and identify it in real life situation. A Javanese manuscript called Buku Jampi could be a solution to this as teachers could introduce plants in local (Javanese) language and highlight the implementation of knowing these plants since the manuscript contain traditional medicine recipes. Although this research is still in its framework, several previous researches showed the positive trends in students’ motivation and comprehension in identification, classification and their local culture as well.
