Effects of Automated Interventions in Programming Assignments: Evidence from a Field Experiment

A typical problem in MOOCs is the missing opportunity for course conductors to individually support students in overcoming their problems and misconceptions. This paper presents the results of automatically intervening on struggling students during programming exercises and offering peer feedback and tailored bonus exercises. To improve learning success, we do not want to abolish instructionally desired trial and error but reduce extensive struggle and demotivation. Therefore, we developed adaptive automatic just-in-time interventions to encourage students to ask for help if they require considerably more than average working time to solve an exercise. Additionally, we offered students bonus exercises tailored for their individual weaknesses. The approach was evaluated within a live course with over 5,000 active students via a survey and metrics gathered alongside. Results show that we can increase the call outs for help by up to 66% and lower the dwelling time until issuing action. Learnings from the experiments can further be used to pinpoint course material to be improved and tailor content to be audience specific.Comment: 10 page

The Skills Shortage and the Payoff to Vocational Education

[Excerpt] Skill demands also appear to be rising within occupations. Increasing numbers of manufacturing workers are working in production cells in which every member of the team is expected to learn every job. Production workers are being given responsibilities--quality checking, statistical process control (SPC) record keeping, resetting machines shown by SPC to be straying from target dimensions, redesigning the layout of the machines in the production cell--that used to be the sole province of supervisors, specialized technicians and industrial engineers. What implications do these changes in skill demands have for the payoff to high school vocational education? Are workers who develop the technical skills taught in trade and technical programs, in fact, more productive when they get a job in the field? Are the skills taught in these programs still valued by the labor market? Has the payoff to high school vocational training increased along with the payoff to other skills? What changes in the way vocational education is delivered are implied by the tight labor markets for highly skilled workers? This paper attempts to answer these questions by examining four different kinds of evidence on the economic payoffs to occupationally specific training in high school

Reading on Grade Level in Third Grade: How Is It Related to High School Performance and College Enrollment?

Illustrates how third-grade reading level correlates with eighth-grade reading level, which, along with ninth-grade school traits, correlates with ninth-grade performance, which in turn correlates with high school graduation and college attendance rates

To cannulate or not to cannulate? Variation, appropriateness and potential for reduction in cannulation rates by ambulance staff

Background: Peripheral intravenous (IV) cannulation is a key intervention in the prehospital setting, but inappropriate use may cause unnecessary pain, distress or risk of infection. The aim of this study was to examine the rate and appropriateness of prehospital cannulation and the relative importance of factors associated with increased likelihood of cannulation. Design and setting: Cross-sectional survey of patients transported in Lincolnshire, East Midlands Ambulance Service. Methods: Retrospective non-identifiable data for September 2006 were extracted. Clinical conditions were classified according to whether they warranted, did not warrant or were uncertain as to the need for cannulation. Other potential indications for cannulation including IV drug administration, reduced consciousness, systolic hypotension, respiratory depression and haemorrhage were combined to determine whether cannulation was indicated. Other variables were investigated as predictors of cannulation. The method of analysis was agreed at the outset. Results: Paramedics cannulated 14.6% (1295/8866) of patients. IV drug administration, clinical indication, reduced conscious level, respiratory depression and hypotension were associated with greater likelihood of cannulation (p,0.001). Cannulation was more likely in older patients but was not associated with gender, haemorrhage or hypoglycaemia. Multivariate logistic regression showed IV drug administration as the strongest predictor of cannulation. Cannulation rates varied threefold by ambulance station (mean 13.4%, 5.8% to 19.0%). It was estimated that 202 (15.6%) of the cannulations performed could potentially have been avoided. Conclusion: Rates of cannulation were higher than previous studies with wide variations between ambulance stations. 15.6% of cannulations performed could have been avoided, thus reducing pain, distress and other potential complications such as thrombophlebitis, extravasation and infection. The generalisability of this study was limited by use of a single site, short duration and dependence on accurate retrospective data. The data demonstrating wide variations suggest that there may be scope for consideration of interventions to reduce cannulation rates

Educational Reform and Technical Education?

[Excerpt] Even though educational reform marches under a banner of economic renewal, the school subjects that appear to be most directly related to worker productivity-- business education, vocational education, economics, computers--have received little attention from reformers. The five core subjects proposed for periodic assessment are English, mathematics, science, history/civics and geography. Yet, if competitiveness is the objective, it is not clear why geography, a subject that is not taught in most American universities, has higher priority than subjects like computers, economics, management and technology? Some of the reform reports have expressed doubt about the economic benefits of vocational education (Committee on Economic Development 1986). Indeed, new graduation requirements introduced by reformers have contributed to an 8 percent reduction in vocational course taking between 1982and 1987

Household wealth and adolescents' social-emotional functioning in schools.

This study attempts a two-part shift in educational research narrowly fixated on the socioeconomic determinants of student test-score performance. First, we focus on variations in how to measure wealth. Second, we move beyond achievement and focus on the wealth determinants of adolescents' social-emotional competencies. Using data from a nationally-representative sample of US eighth graders, we find that the correlation between wealth and social-emotional competencies varies according to how the partitions among the upper class, the middle and working classes, and the poor are defined. By emphasizing wealth in the production of classed social-emotional competencies not captured by test scores, our findings suggest that the growth of household wealth has a more salient effect for lower- and middle-class adolescents than the highest class which appears to have the least to gain, in terms of social-emotional competencies, from an increase in household wealth

From Patient to Student Activation: Development of the Student Activation Measure

The Patient Activation Measure (PAM) was constructed to measure a person’s knowledge, skill, and confidence for self-managing one’s healthcare, or “activation” (Hibbard, Stockard, Mahoney, & Tusler, 2004). The Student Activation Measure (SAM) extends this definition to secondary education. The SAM is a short, positively worded measure that is intended to guide intervention planning. Six hundred three students from two disparate high schools located in the Pacific Northwest completed the measure and an accompanying demographic questionnaire. The respective schools provided the students’ GPAs and attendance records. Using Rasch modeling, the SAM evidenced excellent reliability and construct validity. One-way ANOVAs with post hoc Scheffe’s tests showed that higher SAM scores had significantly higher GPAs, fewer absences, increased time spent on homework, and less time spent on social media or playing video games. Overall, the SAM showed promise as both a research and intervention tool. In addition, the concept of activation has the added benefits of ease of measurement and bridges the gap between evidence-based practices in medicine and secondary education. Further research is needed to understand the properties of the SAM when used with students diagnosed with learning impairing disorders such as ADHD

Predicting university performance in psychology: the role of previous performance and discipline-specific knowledge

Recent initiatives to enhance retention and widen participation ensure it is crucial to understand the factors that predict students' performance during their undergraduate degree. The present research used Structural Equation Modeling (SEM) to test three separate models that examined the extent to which British Psychology students' A-level entry qualifications predicted: (1) their performance in years 1-3 of their Psychology degree, and (2) their overall degree performance. Students' overall A-level entry qualifications positively predicted performance during their first year and overall degree performance, but negatively predicted their performance during their third year. Additionally, and more specifically, students' A-level entry qualifications in Psychology positively predicted performance in the first year only. Such findings have implications for admissions tutors, as well as for students who have not studied Psychology before but who are considering applying to do so at university
