We report the results of a quasi-experimental evaluation of a mystery shopper intervention in Zacatecas and Guadalupe, Mexico. Underage youth attempted to purchase beer at 50 Modelorama stores and 32 Oxxo stores (intervention groups), and at 19 comparison convenience stores in March, July, and August 2018. After each attempt, intervention store operators were informed if a sale was made. Modelorama operators also received training and were warned that repeated sales to minors could jeopardize their franchise. Average sales rates to minors were 63.8% at Modeloramas, 86.5% at Oxxo stores, and 98.2% at comparison stores. The findings suggest that mystery shopper interventions with training, feedback to store operators, and sanctions after repeated sales to underage youth may reduce sales to minors in low- and middle-income countries.

Authentic Environment

This study was carried out to evaluate the effectiveness of mobile learning app based on collaborative learning in authentic environment (known as AKSES) and its impact on the preschool students’ basic scientific process skills competency namely; observation, classification and communication. In addition, the study also investigated competency patterns of the students’ skills. This study was a quantitative study which used two sets of instruments which looked into AKSES application and marking rubrics of the students’ basic scientific process skills. Based on quasi-experimental study, the duration of the study was seven weeks and six learning activities were implemented. Two rural preschools were selected based on quota sample selection and 25 students were in each controlled and treatment groups. Analysis of the survey data was carried out in the form of descriptive and inferential analysis involving Mann-Whitney U test. The Mann-Whitney U test analysis found significant differences in competency patterns of basic scientific process skills in both groups. Meanwhile, the competency patterns of basic scientific process skills indicated positive increase among all preschool students after the utilization of AKSES application in learning activities based on collaborative learning strategy in an authentic environment.
