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

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

Scientific Illiteracy: Causes, Costs and Cures

[Excerpt] This article examines the causes of the learning deficits in science, math and technology, evaluates their social costs and then recommends policy measures for remedying the problems identified. Following the American Association for the Advancement of Science\u27s Science for All Americans report, I define the domain of science very broadly to include mathematics and technology along with the natural sciences. To avoid confusing readers accustomed to the narrower definition of science, broadly defined science is referred to as science, mathematics and technology

Teacher Credentials and Student Achievement in High School: A Cross-Subject Analysis with Student Fixed Effects

We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed effects, which helps minimize any bias associated with the non-random distribution of teachers and students among classrooms within schools. We find compelling evidence that teacher credentials affect student achievement in systematic ways and that the magnitudes are large enough to be policy relevant. As a result, the uneven distribution of teacher credentials by race and socio-economic status of high school students -- a pattern we also document -- contributes to achievement gaps in high school.

Student and School Predictors of High School Graduation in California

Based on surveys of tenth-grade students, teachers, principals, and parents, identifies alterable factors that predict high school graduation, including the student's ninth-grade performance, engagement in sports, and the school's academic climate

Predicting time to graduation at a large enrollment American university

The time it takes a student to graduate with a university degree is mitigated by a variety of factors such as their background, the academic performance at university, and their integration into the social communities of the university they attend. Different universities have different populations, student services, instruction styles, and degree programs, however, they all collect institutional data. This study presents data for 160,933 students attending a large American research university. The data includes performance, enrollment, demographics, and preparation features. Discrete time hazard models for the time-to-graduation are presented in the context of Tinto's Theory of Drop Out. Additionally, a novel machine learning method: gradient boosted trees, is applied and compared to the typical maximum likelihood method. We demonstrate that enrollment factors (such as changing a major) lead to greater increases in model predictive performance of when a student graduates than performance factors (such as grades) or preparation (such as high school GPA).Comment: 28 pages, 11 figure

Class tournament as an assessment method in physics courses : a pilot study

Testing knowledge is an integral part of a summative assessment at schools. It can be performed in many different ways. In this study we propose assessment of physics knowledge by using a class tournament approach. Prior to a statistical analysis of the results obtained over a tournament organized in one of Polish high schools, all its specifics are discussed at length, including the types of questions assigned, as well as additional self- and peer-evaluation questionnaires, constituting an integral part of the tournament. The impact of the tournament upon student improvement is examined by confronting the results of a post-test with pre-tournament students’ achievements reflected in scores earned in former, tests written by the students in experimental group and their colleagues from control group. We also present some of students’ and teachers’ feedback on the idea of a tournament as a tool of assessment. Both the analysis of the tournament results and the students’ and teachers’ opinions point to at least several benefits of our approach

Assessing Learning Outcomes in Middle-Division Classical Mechanics: The Colorado Classical Mechanics/Math Methods Instrument

Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning. As part of an effort to systematically improve our sophomore-level Classical Mechanics and Math Methods course (CM 1) at CU Boulder, we have developed a tool to assess student learning of CM 1 concepts in the upper-division. The Colorado Classical Mechanics/Math Methods Instrument (CCMI) builds on faculty consensus learning goals and systematic observations of student difficulties. The result is a 9-question open-ended post-test that probes student learning in the first half of a two-semester classical mechanics / math methods sequence. In this paper, we describe the design and development of this instrument, its validation, and measurements made in classes at CU Boulder and elsewhere.Comment: 11 pages, 6 figures, 1 tabl
