Introductory Computing

In this investigation, the use of the Alice programming language in an introductory computing class was studied from both a quantitative and qualitative perspective. Students in an introductory computing class participated in a 2.5–week unit to learn programming through the graphical programming environment of Alice. Quantitatively, students were surveyed before and after their Alice experience. One hundred and fifty-four students completed a short questionnaire about their enjoyment and confidence with computer programming along with a content test about their understanding of computer programming concepts. After the students completed a short tutorial on Alice and completed two short programming exercises, they completed the same questionnaire and content test. Qualitatively, three focus groups were held and students were asked to comment on their experience. Students were also required to write an essay requiring them to reflect on their Alice experiences. Data from student reflective essays were coded and analyzed Both the t-tests of the pre- and post-test survey data and the analysis of student essays show that students show significant increases in enjoyment of programming, confidence in programming, and understanding of programming concepts. Focus group comments provide additional insight to these findings.

Introductory Computing

Students in an introductory computing class participated in a study investigating the impact of using a graphics programming environment (Alice) and pair-programming on confidence, enjoyment and achievement. Sixty-four participants completed a short questionnaire and a content pre-test about computer programming concepts. Students were then assigned to one of two groups: individual or paired. The pairs completed a tutorial on Alice and then completed a short assignment over a period of one week working as a team of two. The individuals completed the same tutorial and assignment but completed it alone. Lastly, all participants took the same questionnaire and content post-test. The results showed that all students experienced increased confidence in programming, that students in pairs enjoyed programming more than students who worked individually, and that all students performed significantly better on the content post-test.

In a society where anthropocentrism prevails in relation to ecocentrism, it is important to focus on didactic strategies that lead to the change of attitudes toward an ecocentric vision of the world. The Rivers Project is an Iberian project of public participation in action in our country for 12 years and uses an effective methodology for changing environmental attitudes in children in the first years of schooling. The present study aimed to assess the influence of the Rivers Project on the change of anthropocentric vision for an ecocentric vision in children of the primary school. For this, a questionnaire with open and closed questions was applied to two groups of the 4th year of primary school in the city of Bragança, namely a focus group (121 students) and a control group (33 students). The questionnaire was applied to the focus group before and after an educational intervention (pre and post-test), namely two field trips within the Rivers Project, and the control group in the same time periods, with students who did not make this field trips to the river. The question concerning the purpose of this communication was the drawing up of a drawing that mirrored its representation of a river and its banks. The resulting drawings were analyzed and categorized and were subsequently checked for statistically significant changes through the Wilcoxon test between pre and post-test in both groups. The results show that changes occurred in the focal group. The majority of the children went from an anthropocentric vision to an ecocentric vision after leaving the Rivers Project, thus evidencing the effectiveness of this Project in changing environmental attitudes.

Abstract. In a recent paper, Ferrer and Pardo (2014) tested several distribution-based methods designed to assess when test scores obtained before and after an intervention reflect a statistically reliable change. However, we still do not know how these methods perform from the point of view of false negatives. For this purpose, we have simulated change scenarios (different effect sizes in a pre-post-test design) with distributions of different shapes and with different sample sizes. For each simulated scenario, we generated 1,000 samples. In each sample, we recorded the false-negative rate of the five distribution-based methods with the best performance from the point of view of the false positives. Our results have revealed unacceptable rates of false negatives even with effects of very large size, starting from 31.8% in an optimistic scenario (effect size of 2.0 and a normal distribution) to 99.9% in the worst scenario (effect size of 0.2 and a highly skewed distribution). Therefore, our results suggest that the widely used distribution-based methods must be applied with caution in a clinical context, because they need huge effect sizes to detect a true change. However, we made some considerations regarding the effect size and the cut-off points commonly used which allow us to be more precise in our estimates.

The Individual

Background Multilevel data can be missing at the individual level or at a nested level, such as family, classroom, or program site. Increased knowledge of higher-level missing data is necessary to develop evaluation design and statistical methods to address it. Methods Participants included 9,514 individuals participating in 47 youth and family programs nationwide who completed multiple self-report measures before and after program participation. Data were marked as missing or not missing at the item, scale, and wave levels for both individuals and program sites. Results Site-level missing data represented a substantial portion of missing data, ranging from 0–46% of missing data at pre-test and 35–71% of missing data at post-test. Youth were the most likely to be missing data, although site-level data did not differ by the age of participants served. In this dataset youth had the most surveys to complete, so their missing data could be due to survey fatigue. Conclusions Much of the missing data for individuals can be explained by the site not administering those questions or scales. These results suggest a need for statistical methods that account for site-level missing data, and for research design methods to reduce the prevalence of site-level missing data or reduce its impact. Researchers can generate buy-in with sites during the community collaboration stage, assessing problematic items for revision or removal and need for ongoing site support, particularly at post-test. We recommend that researchers conducting multilevel data report the amount and mechanism of missing data at each level.
