A total of 20 pre-service chemistry teacher enrolled on Curriculum course were the subject of this research. The data of pre-service chemistry teacher ability in constructing CoRe were collected according to the document which consist a questions on pedagogical aspect. There were 9 indicators were used as a references to explored the pre-service chemistry teacher ability in constructing CoRe. The data of pre-service chemistry teacher ability in constructing CoRe were analysed according to descriptive quantity technique by classifying the mean score obtained into five categories from very good to very poor. The result of this study showed that the pre-service chemistry teacher ability in constructing CoRe were pretty good, thus it can be concluded that pre-service chemistry teacher were ready to conducted a quality chemistry learning.

Although Frank Stella intended to create flat, illusion-less Irregular Polygons paintings, it is not uncommon to experience the illusion of colour depth, based on the interaction between their fluorescent and conventional colours. Some critics praised these artworks’ flatness, while others described odd depth experiences that they categorised as a new kind of illusion. In order to provide a correct reading of these works and to reassess their art historical significance, a scientific case study regarding this colour-depth effect imposes itself. This article discusses an experiment in which we determined whether twenty artists, twenty art historians and twenty laypeople experienced fluorescent colours as protruding, receding or flat in combination with conventional colours. We additionally looked at whether they still perceived colour depth when all fluorescent colours were replaced with their conventional variants. All participants observed fifteen designs, which they had to rate according to the perceived depth of each coloured region with a number between −3 (strongly receding) and +3 (strongly protruding). The results revealed that most participants experience fluorescent regions as strongly protruding, unlike all conventional colours, which were rated as much less protruding. When a fluorescent colour was swapped with a conventional variant, all participants experienced significantly less depth. The differences between the subject groups were statistically negligible when looking at the mean depth ratings for both colour types. However, we discovered that artists experienced more contrast effects, as they gave different ratings to different panels (of identical colour and shape) in the same design, depending on their position.

This study was intended to find out the students’ ability in reading descriptive text. Reading skills are considered as an important skill and are uneasy to acquire. In this study, there were 40 students of the second year students of SMAN 1 Sikur are involved as the subject of this study. The method used in this research is a quantitative study. In collecting the data, the writer used a reading test. The data were analyzed through basic statistical computation. To find out their ability and difficulties in reading descriptive text, the test was used which consists of 25 items to students in the form of multiple choice. The test score for each item was 0.4 points. The result of data analysis showed that the mean score of the second year students of SMAN 1 Sikur in reading the descriptive text was fairly good. There were 21 (52.5%) students who were in a high position and 19 (47.5%) students were in a low position. Although 52.5% of students in a high position and 47.5% in a low position, the students’ mean score shows a low position, it is 7.2 mean score which classified as fairly good. Therefore, the ability of the second year students of SMAN 1 Sikur has not been in a high position which is categorized from excellent to good score level. This is caused by the lack of reading strategy and vocabulary. The two weaknesses become students’ difficulties in reading descriptive text.
