Situation emotion understanding is necessary for interpersonal communication and social interaction. Based on the situation of emotion understanding about autistic children literature at home and abroad, this article analyzed the characteristics of autism situational emotion intervention research, including the research object, research purpose, experimental design, data collection method, intervention method, intervention effect and so on. On this basis, some reflections and suggestions are put forward for the followup intervention.

ABSTRACT This study aims to determine the effect of the application of blended learning on the learning outcomes of class X MIA students at SMA PGRI 2 Padang. This study used a pre-experimental design in the form of a One-Shot Case Study by taking research subjects by Purposive Sampling. The sample of this research was the students of class X MIA. This study used descriptive questions as a final test instrument. The data analysis technique used in this research was a t-test. Based on the data collection techniques and data analysis carried out, it was obtained that tcount = 1.81 and ttable = 1.68, because tcount > ttable, then reject H0 at a significant level of 0.05 so it can be concluded that there is an effect of applying blended learning on studensts’ learning outcomes of class X MIA at SMA PGRI 2 Padang. Keywords: Blended Learning, Learning Outcomes

This present research was conducted in order to find out the improvement in students’ listening comprehension and to figure out whether students’ interest in listening class increases after being taught the aspects of connected speech. This research used a quantitative method with pre-experimental design, namely pre-test post-test involving only the experiment group. The population of this research was all the students of the eleventh-grade who are studying at MAS Darul Ihsan which amount to 184 students. In addition, the sample of this research was 30 students of class XI F that was chosen using purposive sampling. Moreover, this research used pre-test and post-test as well as questionnaires as data collection instruments. The research found that teaching connected speech in the listening classroom improved students’ listening comprehension. This was indicated by the comparison of t-score which is higher than t-table, (3.61 > 2.04). Therefore, the alternative hypothesis (Ha) was accepted and the null hypothesis (Ho) was rejected. Furthermore, the result of students’ response sheets indicated that students have positive perception toward the teaching connected speech and it can increase their interest in learning listening.

Context: Instrument validation is an important facet of survey research methods and athletic trainers must be aware of the important underlying principles. Objective: To discuss the process of survey development and validation, specifically the process of construct validation. Background: Athletic training researchers frequently employ the use of survey research for topics such as clinical instruction and supervision, burnout, and professional development; however, researchers have not always used proper procedures to ensure instrument validity and reliability for the data collection process. Description: Four major methods exist to establish the validity of an instrument: face, content, criterion related, and construct. When developing a survey to measure a previously unexplored construct (eg, an athletic trainer's attitudes toward appropriate exertional heat stroke treatment), researchers should employ a four-step process: (1) defining constructs and content domain, (2) generating and judging measurement items, (3) designing and conducting studies to develop a scale, and (4) finalizing the scale. Clinical Advantages: Establishing the validity of a survey instrument strengthens the data yielded from the data collection process, which allows for greater confidence in the interpretation of the results from the survey. Conclusions: Construct validity, although a time-intensive process, is necessary to ensure accuracy and validity of the survey instrument.

The present research focused on identifying the influence of cognitive processes in the creative lateral thinking of high school students. The work was developed under the positivist paradigm; it was classified as basic, of explanatory level, with quantitative approach, non-experimental design and cross-sectional. The sample, calculated through probabilistic sampling, consisted of 221 students. Two data collection instruments were used: the cognitive processes questionnaire and the lateral thinking questionnaire, which were subjected to content validity by expert judgment and reliability and internal consistency analysis by Cronbach's alpha, reaching values of 0.908 and 0.802, respectively. The analysis of verification by Spearman's rho obtained was 0.762, which determined the significant influence between cognitive processes and lateral thinking. It was concluded that, if procedures and actions that lead to the acquisition of knowledge in a constructive way and by discovery are practiced, creative and perceptive lateral thinking would be developed; then the individual would exhibit imagination and creative behaviors.

The objective of this chapter is to develop a model of the behavior of the ecological consumer in order to know the motivations that influence the decision to purchase organic products in citizens from 25 to 45 years of Mexico. The methodology used in the research is qualitative. It was carried out through the non-experimental design, and with respect to the data collection tool, in-depth interviews were carried out. The results obtained with respect to the factors that influence the purchase decision of the products are accepted the general hypothesis. One of the limitations that the study faced was a limited literature regarding studies related to it in the case of Mexico.

A subset of international scholarship from the full Causality: School Libraries and Student Success corpus comprising empirical studies conducted in non-American locations (n=47) are examined for: geographic distribution, publication outlets, citations, data collection and analysis methods, and research strands. The majority of papers used one experimental design or two or more methods for quasi-experimental design approach for data collection, and used at least one or more often two or more data analysis methods. Six categories describe the research: learning environment, student attributes, teacher and school leadership characteristics, instructional interventions, academic skill development, and external factors for achievement.

The use of virtual reality (VR) in transport research offers the opportunity to collect behavioral data in a controlled dynamic setting. VR settings are useful in the context of hypothetical situations in which real-world data does not exist or in situations which involve risk and safety issues making real-world data collection infeasible. Nevertheless, VR studies can contribute to transport-related research only if the behavior elicited in a virtual environment closely resembles real-world behavior. Importantly, as VR is a relatively new research tool, the best-practice with regards to the experimental design is still to be established. In this paper, we contribute to a better understanding of the implications of the choice of the experimental setup by comparing cycling behavior in VR between two groups of participants in similar immersive scenarios, the first group controlling the maneuvers using a keyboard and the other group riding an instrumented bicycle. We critically compare the speed, acceleration, braking and head movements of the participants in the two experiments. We also collect electroencephalography (EEG) data to compare the alpha wave amplitudes and assess the engagement levels of participants in the two settings. The results demonstrate the ability of VR to elicit behavioral patterns in line with those observed in the real-world and indicate the importance of the experimental design in a VR environment beyond the choice of audio-visual stimuli. The findings will be useful for researchers in designing the experimental setup of VR for behavioral data collection.
