Improving Mathematics Learning Activity and Outcomes through the Culturally Responsive Teaching (CRT) Learning Approach for Class VII Middle School Students

The choice of learning approach carried out by the teacher can influence student activity and learning outcomes. This research aims to determine the application of the Culturally Responsive Teaching (CRT) approach in improving the activity and mathematics learning outcomes of class VII junior high school students. The subjects in this research were students in class VII-A of SMP Negeri 3 Sidoarjo for the 2022/2023 academic year, totaling 32 students. This research uses a research method in the form of Classroom Action Research (PTK) with 2 cycles and each cycle consists of 4 stages, namely the planning stage, action implementation, observation/observation, and reflection. Research data collection techniques include observation, tests and documentation. The results of the research showed that student learning activity in the pre-cycle was still in the low activity category, namely with a percentage of 51.95%, then in cycle I it increased to the moderate activity category with a percentage of 67.09%, and in cycle II it again increased to the high activity category. with a percentage of 79.10%. The percentage of students' classical mathematics learning outcomes in the pre-cycle was 43.75% (14 students in the complete category out of a total of 32 students), then in cycle I it increased to 75% (24 students in the complete category out of a total of 32 students), and in cycle II experienced another increase reaching 81.25% (26 students in the complete category out of a total of 32 students). Based on these results, it can be concluded that the application of the Culturally Responsive Teaching (CRT) learning approach can increase the activeness and mathematics learning outcomes of class VII-A students in the statistical material of presenting data at SMP Negeri 3 Sidoarjo for the 2022/2023 academic year.

Penerapan Model Pembelajaran Kooperatif Tipe Numbered Head Together (NHT) Ditinjau dari Aktivitas Belajar Siswa Kelas VIII SMP

<p>The purpose of this study was to find out the results belejar junior high school students after application of cooperative learning model NHT the terms of the learning activities. Forms of research is quasy Experiment with the design of a 1x3 factorial design. The population in this study were all students of class VIII SMP Negeri 1, while the sample is a class VIII-D randomly selected using random cluster sampling technique. Data collection tool used is a test instrument that consists of four essay and activity questionnaire consisting of 23 questions. Based on analysis test, one way ANOVA with different cells obtained by (1) the learning outcomes of students with high activity category as well as students with moderate activity category. (2) the learning outcomes of students with moderate activity category better with students with low activity category. (3) the learning outcomes of students with high activity category better with students with low activity category.</p><p> </p><p>Keywords: Cooperative learning NHT type, learning activities</p>

Physical Activity Levels in Women Attending Breast Screening, Receiving Chemotherapy and Post-Breast Cancer Treatment; A Cross-Sectional Study

Background: A lack of physical activity (PA) is a well-recognised risk factor in the development of breast cancer (BC) and evidence-base research on the impact of PA on BC survival is consolidating. However, evidence reveals that BC survivors have low levels of PA, suggesting the need of targeted interventions to enhance the PA behaviour of BC survivors. Unfortunately, there is lack of data from the UK about the PA behaviours of women at various stages of diagnosis and treatment of BC. Therefore, the aim of the present study was to assess PA levels in women at different stages of BC pathway. Patients and Methods: A convenient sample of patients was selected at various stages of presentation and treatment of BC. Patients attending for breast screening for NHSBSP (n = 188), post-operative patients attending for chemotherapy (n = 41) and BC patients within one year’s post-treatment (n = 80) were invited to take part in this cross-sectional study. Results: Based on the odds ratio, the likelihood of a chemotherapy participant not meeting PA guidelines (i.e., being in the low activity category) were three times higher than the odds of a NHSBPS attendee not meeting PA guidelines, and compared to post-treatment participants, the chemotherapy patient’s odds of not meeting PA guidelines was four times higher. The odds of NHSBPS attendees being in the high activity category compared to the moderate category were three times higher than that of a post-treatment participant. Conclusions: The current study suggests the need to establish robust PA interventions to enhance the PA behaviour of breast cancer survivors.

Variabilities in aerosolizing activities and airborne fungal concentrations in a bakery.

Concentrations of airborne culturable fungi were measured in the kitchen of a bakery in Boston, Mass., to evaluate variabilities associated with common worker activities, outdoor aerosol distributions, and season. Activities were categorized as early morning preparation, cornmeal sifting and tossing, flour dumping and mixing, sweeping, and low activity. Sets of measurements were taken over 1 day in spring and 1 day in summer. Fungal concentrations were measured using a one-stage culture plate impactor, and bulk samples were taken from suspected fungal reservoirs within the bakery and subsequently cultured. Compared with the low activity category, elevated levels of total culturable fungi were found during all other activities, with the amount of increase closely related to individual worker activity as well as outdoor concentrations and initial bakery conditions. In the spring, Penicillium was the dominant genus showing activity-related elevations in concentrations, while Cladosporium was the dominant genus during the summer. Clearly, due to variabilities in worker activities and ambient fungal concentrations, a standardized sampling protocol involving a large sample size over multiple days is needed to estimate accurately exposure to either total airborne fungi or specific fungal taxa.
