The aim of this study was to investigate the enhancement of the mathematical understanding ability of pre-service mathematics teachers through Activity-Class Discussion-Exercise (ACE) teaching cyclic based on APOS theory. This study used a quasi-experiment method with non-equivalent pre-post test control group design. The subjects of this study were 120 pre-service mathematics teachers from two universities in Palembang, Indonesia. The subjects were divided into two class, that is, experiment and control class. Experiment class was a class that is applied ADE teaching cyclic based on APOS theory, whereas control class was a class that is applied direct learning. The subjects were also divided into three groups of mathematical initial ability, that is, high, average, and low. The Instruments used in this study were mathematical initial ability test, mathematical understanding ability test, observation, and interview. Data analysis tests used in this study were statistic test of parametric and non-parametric. The results of data analysis showed that 1) there is no significant difference between the improvement of mathematical understanding ability of pre-service mathematics teachers applied ACE teaching cyclic based on APOS theory and direct learning in terms of overall and the group of mathematical initial ability, 2) there is no interaction between learning factors (APOS and direct learning) and the group of mathematical initial ability (high, average, and low) to the improvement of mathematical understanding ability of pre-service mathematics teachers.

BACKGROUND Background: Postoperative Fatigue Syndrome (POFS) occurs in almost every patient who has undergone major surgery. With the ever-increasing attention of people on rehabilitation treatment, POFS has received unprecedented attention. OBJECTIVE Objective: Based on modern data analysis, acupuncture treatment is optimized intelligently, and its efficacy in breast cancer patients with POFS is explored. METHODS Methods: In this study, the acupuncture and moxibustion in traditional Chinese medicine were combined to optimize the formation of warm acupuncture therapy, and then the research on warm acupuncture was optimized using modern data analysis methods. At first, the statistics of personal information and operation of 60 patients with breast cancer was carried out. The statistical results were analyzed by rank sum test and independent sample T test. The Visual Analogue Scale (VAS), Brief Profile Of Mood State (BPOMS), and Identity-Consequence Fatigue Scale (ICFS) were utilized to analyze the fatigue degree, mental state, and fatigue state of the patients. RESULTS Results: There was no significant difference in age (U = 473.34, P = 0.583) and education level (U = 479.20, P = 0.613) between the experimental group and the control group (P > 0.05), which were comparable. Compared with the control group, the VAS values of the experimental group on the 3rd day (P = 043), 7th day (P = 0.039), and 14th day (P = 0.030) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). In the experimental group, the BPOMS values on the 3rd day (P = 0.042), 7th day (P = 0.035), and 14th day (P = 0.031) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). The ICFS values of the experimental group on the 3rd day (P = 046), 7th day (P = 0.037), and 14th day (P = 0.031) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). The variance of transferrin levels was uniform on the 7th day after operation (F = 0.679, P = 0.433 > 0.005), with a significant difference (T = -2.985, P = 0.008 < 0.05). CONCLUSIONS Conclusions: Warm acupuncture therapy could effectively improve the POFS of breast cancer patients, which was a safe and effective treatment. CLINICALTRIAL

This study aims to determine the effect of practicum-based direct learning model on science process skills and students' critical thinking skills. This study is a quasi-experimental research with the Pretest-posttest Control Group Design. The sampling technique using Cluster Random Sampling. The sample in this study were students of class XI IPA 1 (18 students) as the experimental class and class XI IPA 2 (18 students) as the control class in AL-Hamzar High School Tembeng Putik. The research instruments used were learning implementation observation sheets, the science process skills observation sheets, and learning achievements tests. The data obtained were analyzed using the t test with the help of SPSS 16. The results of data analysis showed that the implementation of learning in the first meeting reached 81% and the second meeting 96% with a very good category. The students’ science process skills in both classes show that students' science process skills varies. The students’ critical thinking ability in the experimental class was higher than the control class. The results of pretest data analysis showed that students' critical thinking ability in the experimental class was 35.5 while the control class was 49.5. Students' critical thinking ability in post-test increased in the experimental class to 73.5 while the control class was 58.6. The results of the t-test show that tcount > ttable (3.45 > 2.04) so it can be concluded that the practicum-based direct learning model was affect toward students' science process skills and  critical thinking ability.

Ipad Apps

The use of iPads® in the classroom is growing. In the 2013–14 school year, 57 percent of schools planned to invest in iPads (Netop 2013). This investment can benefit mathematics classrooms only if teachers know which apps they can use to help students develop deeper mathematical understanding. Although learning about and developing facility with various apps is valuable for mathematics teachers, the process can be difficult, overwhelming, and time-consuming. To get started, we recommend one app, Dropbox, that can be used to share materials within the classroom setting, and then we suggest three free, easy-to-use mathematics apps: Sketchpad Explorer, Data Analysis, and MathGraph (see the table on p. 711).

The quantitative study is aimed to know whether documentary films can be applied to foster students' critical thinking skills. This research was conducted in Class X SMA Negeri 10 Sidenreng Rappang, with a total population of 72 students. Samples were drawn from the entire population by taking 2 classes, namely X IPA as an experimental group of 26 students and X IPS as a control group of 25 students. Data were collected through a critical thinking ability test instrument based on critical thinking indicators, then processed with data analysis using the Mean score (average) and SPSS 2.0. Results of the study showed that the experimental group, which were taught to use the documentary, obtain average value is higher compared with the controls group in fostering the ability to think critically, especially on the subjects of Indonesian with developing materials with the opinion of exposition text. Average score results in critical thinking skills with a documentary film is 91.76 with the results of a significant test of the test independent of 10.878 while the average score of the results that are taught without using documentary 70.84 with value significant 2.009. Based on the results of data analysis, this present study ascertained that documentary films could foster students' critical thinking skills.
