<p style="text-align: justify;">Assessment is a topic that continues to be developed in science education research. Assessment evaluates not only students' cognitive abilities but also their thinking skills. Therefore, in this study, an assessment that could measure students' chemical literacy was developed. Chemical literacy is a thinking skill that students must develop as part of their chemistry learning. The goal of this study was to assess item' quality, as well as student’ chemical literacy on the concept of chemical rate. The Rasch model was employed to analyze the data in this study. The results of this study depict that the developed assessment had sufficient reliability and validity to be used to assess students' chemical literacy. Furthermore, the analysis of the students’ responses to the items revealed that many students did not understand or were unaware of the context presented. These findings suggest that students' chemical literacy in the material for the reaction rate is still lacking and needs to be improved. As a result, the teacher's role in assisting students in improving their chemical literacy through chemistry learning is critical.</p>

The Malaysian government estimated that in 2013, 5.5% of the Malaysian population comprises of senior citizens aged 60 years old and above. Recent research had revealed that 14.3% of the older Malaysians are at risk of Major Neurocognitive Disorder (MND; also known as dementia). As the elderly population increases gradually in the country, the chances of them suffering from MND are also expected to increase. MND is often associated with a decline in memory or thinking skills which are severe enough to affect the ability to perform everyday activities among those who are diagnosed with these symptoms. Cognitive Stimulation Therapy (CST) is a brief treatment for those suffering from mild to moderate MND. However, the efficacy of this treatment has not been evident in Malaysia.The aim of the present study is to identify the effectiveness of CST in stabilizing the declination of cognitive functions, as well as improving the quality of life among elderly suffering from mild to moderate MND. Thirty elderly diagnosed with mild and moderate MND will be invited to participate in a single group pre-post trial, involving a 45 minute CST treatment to be administered for 14 weeks on a regular weekly basis. The participants will be selected from residents of care centers elderly at Klang Valley area. The outcomes and effectiveness of the CST will be determined by the Montreal Cognitive Assessment (MoCA), and Quality of Life-Alzheimer’s Disease (QOL-AD). The former instrument will be used to examine the cognitive abilities of the elderly, while the latter will be used to determine issues related to the quality of life based on the participant and caregivers rating report. As the CST efficacies has been proven in several countries such as the United Kingdom, Hong Kong and Japan, the present study anticipates that it will also be effective in the Malaysia context and helps in treating MND.

Learning motivation was something that exists in an individual mind for doing something to achieve the goal. Motivation was needed to improve the cognitive abilities of each individual. In reality, there are still students at the Chemical Education Study Program who were less motivated to learn. This was characterized by active, discipline, task completion, the willingness of student to ask questions and solve problems in learning is still lacking. The aim of this study was to determine the level of motivation, influencing factors and efforts to increase student motivation in chemistry learning. The results showed that student's motivation in improving cognitive abilities on average was still low. The efforts were made by lecturers are to instil the values that can motivate the learning process, apply the better strategies and quality of teaching, approach individually or groups to improve the lecturer skills and apply the contextual based learning.

<p>In using the Rasch model to improve the quality of an instrument, analysis purports to determine if the sample collaborates well with the items in the instrument such that the results are measuring a single underlying variable. The relevant properties of Rasch analysis are reliability and validity which are key indicators of the quality of a measurement instrument. This paper discusses the use of one type of Rasch model that is the Partial Credit Model to investigate reliability and validity of an instrument. By removing or changing items in the instrument when conditions of reliability and validity are not met, the quality of the instrument is improved.</p>

Context Of Learning

High Order Thinking Skills (HOTS) are a significant part of the implementation of the 2013 Curriculum to develop student competencies in the 21st century. Not only in the context of learning are HOTS considered important. They contribute to the National Examination held in Indonesia, so careful preparation for this exam is needed. Chemistry has basic concepts that require students to search and find facts, understand concepts, apply them procedurally, and analyze deeply. This study aims to map the analysis ability of students in Yogyakarta in working on HOTS-based chemistry national exam questions. This research is a quantitative-qualitative descriptive study with XII year students at a senior high school in Yogyakarta. The instruments used in this study were HOTS essay questions, interview sheets, and questionnaire sheets, analyzed with the Rasch Model. The results show that the students' analysis ability was still relatively low, with person reliability values of 0.56 and 0.39, and a Cronbach's alpha of 0.78. The quality of the HOTS questions was very good, with item reliability 0.97 and 0.95. Not many students in the two senior high schools have good analysis ability, so students must be better trained to optimize their potential in HOTS-based chemistry learning.

Abstract Background Juvenile idiopathic arthritis (JIA) may seriously affects patients’ quality of life (QoL), but it was rarely focused and studied in China, so we explore JIA children’s QoL using Chinese version of the PedsQL4.0 Generic Core and PedsQL3.0 Rheumatology Module scale, and analyzed the psychometric properties of these two Scales among Chinese JIA children. Methods We recruited 180 JIA patients from Children's Hospital Affiliated to Capital Institute of Pediatrics and Hebei Yanda Hospital from July 2018 to August 2019. The questionnaires include information related on JIA, PedsQL4.0 generic core and PedsQL3.0 Rheumatology Module scales. According to the disease type, onset age of and course of JIA, we divided them into different groups, then compared the QoL status among different groups. Moreover, we analyzed the reliability and validity of these two scales in these 180 JIA children. Results The mean score of PedsQL4.0 generic core scale on these 180 patients was 82.85 ± 14.82, for these in active period was 72.05 ± 15.29, in remission period was 89.77 ± 9.23; the QoL score of systemic, polyarticular and oligoarticular JIA patients were 77.05 ± 19.11, 84.33 ± 12.46 and 87.12 ± 10.23. The mean score of PedsQL3.0 Rheumatology Module scale on 180 patients was 91.22 ± 9.45, for these in active period was 84.70 ± 11.37, in remission period was 95.43 ± 4.48; the QoL score of systemic, polyarticular and oligoarticular JIA patients were 89.41 ± 11.54, 89.38 ± 10.08 and 93.71 ± 6.92. In the PedsQL 4.0 Generic Core scale, the α coefficients of total scale and almost every dimension are all greater than 0.8 except for the school activity dimension of 0.589; the correlation coefficients of 22 items’ scores (total 23 items) with the scores of dimensions they belong to are greater than 0.5 (maximum value is 0.864), and the other one is 0.406. In PedsQL3.0 Rheumatology Module scale, except for the treatment and worry dimensions of 0.652 and 0.635, the α coefficients of other dimensions and the total scale are all greater than 0.7; the correlation coefficients of all items’ score were greater than 0.5 (the maximum is 0.933, the minimum is 0.515). Conclusions The QoL of Chinese JIA children is worse than their healthy peers, these in active period and diagnosed as systemic type were undergoing worst quality of life. The reliability and validity of PedsQL 4.0 Generic Core and PedsQL3.0 Rheumatology Module scale in Chinese JIA children are satisfactory, and can be used in clinical and scientific researches.
