The current study is conducted to explore the learning potential of students at the elementary level by using the scaffolding technique. The study aimed to measure the efficiency of the scaffolding teaching method provided to the students at the elementary level. As it was an experimental study, so, no population was defined. The sample was selected from Gov. Girls Higher Secondary SchoolModel Town A, Bahawalpur, Punjab, Pakistan. All 6th classes of this school were included to analyze the effect of scaffolding as an intervention. Retention of learning after 3 months, the provision of scaffolding in comparison to the traditional method was assessed. After the posttest, there was a retention test as the final test from all four groups. Solomon's four-group design was used for this experiment in which there were 40 students in each group and 160 total participants. In the current study, Pretest, posttest, and after 3months retention test was conducted as research tools. To analyze the data, SPSS version 20 one-sample t-test were used to analyze the data. The Data revealed that scaffolding was proved to be a better strategy compared to the control group. Even the results of retention of learning skills were higher than the control group. Students showed good understanding, remembering, and better-solving processes in experimental groups. Study recommended that scaffolding teaching needs a highly structured supervised environment and may be conducted in controlled conditions. It is recommended that in teacher education, the prospective teachers may be prepared in the principles, procedures, and rules of scaffolding. A due consideration may be given to teaching strategies in all teacher education programs in the country as it is an innovative and progressive way of teaching.

The aim of the work is a comparative analysis of three frameworks designed for building web applications for the Java programming language: Spring Boot 2.4.4, Micronaut 2.5.4 and Quarkus 1.13.4.Final. Test applications were prepared, equipped with the same functionality as used in the experiment consisting in measuring the server response times to a POST request – performing the data entry into the database. For each test application, the scenario aimed at measuring the time of handling requests under various load conditions was repeated five times. During each repetition of the scenario, the load which was the average number of requests sent per second by virtual users was increased. In parallel with performance tests, the reliability of the test applications was measured. Reliability was defined as the percentage of requests sent to the server that ended in a failure. The comparative analysis also took into consideration the volume of the code of the test applications based on the selected frameworks. The performed analyses showed that in terms of all the criteria considered in this work Micronaut proved to be the best framework.

ABSTRACT Introduction Airway obstruction is the third most common cause of preventable death on the battlefield, accounting for 1%–2% of total combat fatalities. No previous surgical cricothyroidotomy (SC) studies have analyzed the learning curve required to obtain proficiency despite being studied in numerous other surgical technique training experiments. The aims of this study were to establish expert SC performance criteria, develop a novel standardized SC curriculum, and determine the necessary number of practice iterations required by a novice to reach this pre-determined performance goal. Materials and Methods A standardized checklist and SC performance standards were established based on the performance of 12 board certified Military Health System surgeons with prior experience on performing a SC using a simulated trauma mannequin. Expert-level criteria were defined as a SC time to completion of 40 s or less and checklist score of at least 9/10, including all critical steps. Study subjects included 89 novice providers (54 active-duty first- and second-year medical students and 35 Navy corpsmen). Subjects received instruction on performing a SC using the principles of mastery learning and performed a final test of SC proficiency on a trauma mannequin within a realistic simulated MEDEVAC helicopter. The total number of subject practice attempts, checklist scores, and time to completion were measured and/or blindly scored. Learning curve and exponential plateau equations were used to characterize their improvement in mean time to SC completion and checklist scores. Results Mean pre-test knowledge scores for the entire group were 11.8 ± 3.1 out of 24 points. Total mean practice learning plateaued at checklist scores of 9.9/10 after 7 iterations and at a mean completion time of 30.4 s after 10 iterations. During the final test performance in the helicopter, 67.4% of subjects achieved expert-level performance on the first attempt. All subjects achieved expert-level performance by the end of two additional attempts. While a significantly larger proportion of medical students (79.9%) successfully completed the helicopter test on the first attempt compared to corpsmen (54.3%), there were no statistically significant differences in mean SC completion times and checklist scores between both groups (P > 0.05). Medical students performed a SC only 1.3 s faster and scored only 0.16 points higher than corpsmen. The effect size for differences were small to negligible (Cohen’s d range 0.18–0.33 for SC completion time; Cohen’s d range 0.45–0.46 for checklist scores). Conclusion This study successfully defined SC checklist scores and completion times based on the performance of experienced surgeons on a simulator. Using these criteria and the principles of mastery learning, novices with little knowledge and experience in SC were successfully trained to the level of experienced providers. All subjects met performance targets after training and overall performance plateaued after approximately seven iterations. Over two-thirds of subjects achieved the performance target on the first testing attempt in a simulated helicopter environment. Performance was comparable between medical student and corpsmen subgroups. Further research will assess the durability of maintaining SC skills and the timing for introducing refresher courses after initial skill acquisition.

Electricity is needed by the community because it is easily converted into other forms of energy. Electricity is very useful but at the same time dangerous for humans if they do not have the knowledge, understanding and skills about it. This training was carried out with the aim of providing knowledge about electrical hazards and skills in electrical installation for residents of RW 15, Ciwaruga Village, Parongpong District. With the materials and methods and approaches applied, the training can run smoothly and work well. This success is shown by the active participation and high enthusiasm of the participants during the training and the high level of absorption of the training materials delivered. This is reflected in the increase in knowledge and skills in terms of making good installations as indicated by the increase in the value of the final test results (posttest). In addition, this paper can also be used as a reference for parties who will carry out similar or other activities related to electrical installations.

This study’s objective was to evaluate a MOOC constructed from educational principles based on behavioral theory. The evaluation included the analysis of the performance, retention, and perception of the students. This MOOC consisted of an initial test, three teaching units, a final test and an assessment of the students' perception. The mean grade in the initial test was 6.34 (sd=1.20), and in the last attempt of the final test it was 8.75 (sd=0.51). The difference between these values was statistically significant and the effect size was considered very large. The retention rate was 44%, and 75% of students rated the overall experience as “Very Good”. The evaluated MOOC was effective in teaching its learning objectives and student retention was much higher than the average reported in other studies.These results indicate the relevance of the educational principles used in the elaboration of the MOOC.

The changes of curriculum affect all learning aspects including students. It changes the students’ communication skill, and it can be a problem. To overcome that problem, cooperative learning model is considered to be a solution because this model has many types of strategies such as think pair share (TPS) and send greetings and questions (SGQ). The aims of this study were to investigate the effect of TPS and SGQ implementation toward students’ communicative skills, and to find out the differences of students’ communication skill after learning through TPS and SGQ. This study was a comparative and experimental research. The population was students of Indraprasta University into two classes:1st class consisted of 20 students and the 2nd class consisted of 24 students. The data were attained by using questionnaire for communication skills, observation sheet for the implementation of TPS and SGQ cooperative learning model, and documentation for mid and final test. The result showed that (1) there was a significant effect of TPS implementation toward students’ communication skills; (2) there was a significant effect of SGQ implementation toward students’ communication skills; and (3) there was no difference of students’ communication skills between the implementation of TPS and SGQ cooperative learning model.

he purpose of this study was to analyze the barriers to learning three-dimensional distance material using Didactical Design Research (DDR). The subjects of this study were two groups of class 12. The instruments used in this study were pretest (initial test) and post test (final test) which consisted of a test of the respondent’s ability, interview sheets, and observation notes. The data obtained were analyzed using three DDR steps: (1) didactic situation analysis by recontextualizing, repersonalizing, and developing didactic designs which include PDA (Pedagogical Didactic Anticipation); (2) metapedadidactic analysis by applying PDA; and (3) retrospective analysis linking didactic and metapedadidactic situations. The results showed that the identified learning obstacles can be anticipated by using PDA. The application of the didactic learning design shows that this design can be an alternative to third-dimensional distance learning in grade 12 because it can minimize student learning barriers that have been identified previously.
