This study provides evidence about factors that facilitate the development of computational thinking (CT) in Costa Rican elementary school students, including the description of the contribution of the LIE++ proposal that addresses CT knowledge and practices through programming and physical computing projects. A quasi-experimental design was used to compare a group of students from the LIE++ educational proposal with a group of students from another proposal called LIE-Guides, which emphasizes learning with digital technologies. The study sample comprised 14,795 voluntary students, who answered an online test that was constructed and validated to estimate the scores achieved in CT. The results showed that the students participating in the LIE++ proposal obtained better scores compared to the LIE-Guides group. A multilevel regression model demonstrated that students’ personal and social variables, as well as the proposal’s execution scheme, positively affected student learning in CT. This research is a first approach to the subject in this context. It refers to the importance of providing educational opportunities that focus on more advanced computing knowledge and skills, as well as the relevance of continuing to develop tools and methodologies that help generate evidence about CT in education in order to improve educational interventions. Este estudio proporciona evidencia sobre factores que facilitan el desarrollo del pensamiento computacional (PC) en estudiantes costarricenses de primaria, incluyendo el aporte de la propuesta de LIE++ que aborda conocimientos y prácticas del PC mediante proyectos de programación y computación física. Se utilizó un diseño cuasiexperimental para comparar un grupo de estudiantes de LIE++ con un grupo de estudiantes de otra propuesta llamada LIE-Guías que enfatiza aprendizajes con tecnologías digitales. En el estudio participaron 14.795 estudiantes, respondiendo voluntariamente una prueba en línea que se construyó y validó para estimar los puntajes alcanzados en PC. Los resultados mostraron que los estudiantes participantes de LIE++ obtuvieron mejores puntajes en comparación con el grupo de LIE-Guías y mediante un modelo de regresión multinivel se identificaron que variables personales y sociales de los estudiantes y de la misma ejecución de la propuesta inciden en el favorecimiento de estos aprendizajes. Esta investigación es un primer acercamiento al tema en este contexto, que se refiere a la importancia de brindar oportunidades educativas que apunten a conocimientos y habilidades más avanzadas de la computación, así como a la relevancia de seguir desarrollando herramientas y metodologías que ayuden a generar evidencias sobre el PC en el ámbito educativo y así mejorar las intervenciones educativas.

Health education programs supported by women's groups or workplaces have been successful in reaching large populations and changing intentions to perform breast health behaviors. This study examined the responses women working in the automotive industry had to two health education interventions, mailed pamphlets, and a combination of mailed material and classes at the worksite compared to a control group. A quasi-experimental design was used. Of the 948 women completing the pre-test, 437 also completed the post-test and were highly representative of the initial sample. The findings suggest that although the mailed information produced some change in practices and intentions, the classes in combination with the mailed pamphlets produced greater change. In addition, confidence in breast self examination as a method of detecting an existing breast lump increased from pre-test to post-test across all age groups. The reported influences on the women's decisions related to breast health varied across the life span. The results of this study can be used to support the development of effective health promotion programs for use at workplaces to increase the likelihood of women engaging in healthy breast practices.

The Impact

Computational Thinking (CT) has been placing the focus of educational innovation as a set of troubleshooting skills. Unfortunately, there is not a consensus if the teaching methodology and the available materials attend the expectations of the lecturers. To prove the impact that CT training has in primary school, we attempted to evaluate primary school students with a Quasi-Experimental approach and taking Unplugged CT classes in Brazilian Schools with Social and Economic Vulnerabilities. The research happened in two schools to prove if the activities are effective for students who live in areas where there are no electronic devices, Internet or even electrical power can be also benefited. The results show statistically significant improvement. Our study finds shows that we are able to reinforce the claim that CS unplugged is an effective approach and it is an alternative for students who live in unprivileged areas.

The Impact

AbstractScientific literacy can be promoted through oral and written argumentative practice. Collaborative discourse has proven effective in fostering conceptual understanding, especially when discussions are developed under deliberative goals. Likewise, writing tasks as argumentative syntheses stand out for its epistemic value and its contribution to constructive learning processes. However, there are no known educational interventions that have combined these two didactic activities to teach science. The objective of this research was to compare the impact of four intervention programs, based on deliberative dialogues and argumentative synthesis writing activities, on the learning of socio-scientific content. The four programs resulted from the combination of two instructional components (Explicit Instruction; Guide), while deliberative dialogues and argumentative syntheses were constant elements. We conducted a pre-post quasi-experimental study in which participated 151 Spanish third grade secondary school students. Socio-scientific learning was evaluated through a content test made up of open questions. The results showed all students progressed in their socio-scientific knowledge. Instructional practices did not have a direct effect on content learning. However, we observed an indirect effect of explicit instruction on learning socio-scientific content, through learning of argumentative synthesis writing. Besides, we found a positive relation between progression in synthesis writing and knowledge acquisition.

Study on the use of Instagram has bloomed in EFL teaching learning process. Instagram is one of the favorite SNSs among students. This research aims to discover the effect using Instgram combined with Word Map strategy as learning tool in developing students’ vocabulary by involving 64 Islamic junior high school students. They were asked to do vocabulary level test to measure their mastery in vocabulary. In supporting the data, a questionnaire was also distributed to the treatment group. A quasi-experimental design was employed during the study. A two-way ANOVA was used to analyze the data. The findings revealed that applying Word Map strategy with Instagram significantly improved students’ vocabulary from 11% for the control group to 18.98% for the treatment group. Hence, developing Word Map strategy with mobile application integration to improve students’ writing skill within EFL curriculum is worth investigating.

Abstract This study investigated the discriminant validation of the Test of Reading Performance (TORP), a new scale designed to evaluate the reading performance of elementary-school students. The sample consisted of 181 elementary-school students drawn from public elementary schools in northern Greece using stratified random procedures. The TORP was hypothesized to measure six constructs, namely: “letter knowledge,” “phoneme blending,” “word identification,” “syntax,” “morphology,” and “passage comprehension.” Using standard deviations (SD) from the mean, three groups of students were formed as follows: A group of low achievers in reading (N = 9) including students who scored between -1 and -1.5 SD from the mean of the group. A group of students at risk of reading difficulties (N = 6) including students who scored between -1.5 and -2 SDs below the mean of the group. A group of students at risk of serious reading difficulties (N = 6) including students who scored -2 or more SDs below the mean of the group. The rest of the students (no risk, N = 122) comprised the fourth group. Using discriminant analyses it was evaluated how well the linear combination of the 15 variables that comprised the TORP could discriminate students of different reading ability. Results indicated that correct classification rates for low achievers, those at risk for reading problems, those at risk of serious reading problems, and the no-risk group were 89%, 100%, 83%, and 97%, respectively. Evidence for partial validation of the TORP was provided through the use of confirmatory factor analysis and indices of sensitivity and specificity. It is concluded that the TORP can be ut ilized for the identification of children at risk for low achievement in reading. Analysis of the misclassified cases indicated that increased variability might have been responsible for the existing misclassification. More research is needed to determine the discriminant validation of TORP with samples of children with specific reading disabilities.

The purpose of this study is to explore the influence of introduction of the physical computing strategy of Arduino Boards in a program design course on coding literacy and the effectiveness of the application in technical high school students. This study selected two classes of twelfth-grade students enrolled in a program design course at a technical high school in Southern Taiwan as the samples. One class was the control group (43 students), and the other was the experimental group (42 students). During the 18-week course, the control group carried out a DBL (design-based learning) programming project, and the experimental group carried out the DBL programming project using the physical computing strategy of Arduino boards. Pre- and posttests and a questionnaire survey were carried out, while ANCOVA (analysis of covariance) was used for evaluation purposes. In the course, students in the experimental group were randomly selected for semi-structured interviews to understand their learning status and to perform qualitative analysis and summarization. This study proposed the physical computing strategy of Arduino boards, featuring staged teaching content, practical teaching activities, and real themes and problem-solving tasks. The results show that the coding literacy of students in the different teaching strategy groups was significantly improved. However, in the Arduino course on DBL programming, the students in the experimental group had a significantly higher learning efficiency in coding literacy than those in the control group. Moreover, according to the qualitative analysis using student interviews, Arduino boards were found to improve students’ motivation to learn coding and to aid in systematically guiding students toward improving their coding literacy by combining their learning with DBL theory. Thus, Arduino technology can be effectively used to improve students’ programming abilities and their operational thinking in practically applying programming theories.
