Examining the implementation of technology-based blended algebra I curriculum at scale

Studies on blended education pay little attention to implementation, thus limiting the understanding of how such programs contribute to student math learning. This article examines the implementation of a widely used blended algebra curriculum and the relationship between implementation and student outcomes. The study was conducted in 74 middle schools and 73 high schools in 51 school districts located in seven states. The study included both treatment and control schools. The blended-curriculum combines inquiry-based teaching and learning with technology (math software). The study found that teachers implemented the blended curriculum with low fidelity. Teachers had most difficulty allocating the recommended amount of time for the math lab and content. The study also found that the blended-curriculum teachers in the second year reverted to more traditional approach to instruction and spent less time on inquiry based instruction than in the first year, although they continued to use this approach at a higher level than teachers in the control schools. The study findings suggest that teacher adjustment of instruction in the second year, specifically balancing the amount of traditional instruction with inquiry instruction, in combination to the use of the math software contributed to the performance of the program.     

CHARACTERISTICS OF SUCCESSFUL STUDENTS READMITTED FOLLOWING ACADEMIC SUSPENSION

The study was an investigation of the usefulness of 50 variables in predicting the academic performance of 86 students readmitted to Bronx Community College following academic suspension. The variables included scores on the City University of New York placement tests, the Maudsley Personality Inventory, and the Survey of Study Habits and Attitudes. Other variables included 8 educational history items, 20 biographical items, and students' opinions about the contribution of 12 factors to their previous academic failure. The criterion measure was the academic performance (pass or fail) in the re‐entry semester.

The principal conclusions to be derived from this study are that, for the population of academic failures characterized by average high school achievement and average scholastic aptitude, specific academic skills are important, past academic record seems unimportant, and a general factor called incentive seems important in the attainment of passing grades upon readmission.     

Fluid balance of elite Brazilian youth soccer players during consecutive days of training

Abstract

In this study we investigated pre-training hydration status, fluid intake, and sweat loss in 20 elite male Brazilian adolescent soccer players (mean ± s: age 17.2 ± 0.5 years; height 1.76 ± 0.05 m; body mass 69.9 ± 6.0 kg) on three consecutive days of typical training during the qualifying phase of the national soccer league. Urine specific gravity (USG) and body mass changes were evaluated before and after training sessions to estimate hydration status. Players began the days of training mildly hypohydrated (USG > 1.020) and fluid intake did not match fluid losses. It was warmer on Day 1 (33.1 ± 2.4°C and43.4 ± 3.2% relative humidity; P < 0.05) and total estimated sweat losses (2822 ± 530 mL) and fluid intake (1607 ± 460 mL) were significantly higher (P < 0.001) compared with Days 2 and 3. Data also indicate a significant correlation between the extent of sweat loss and the volume of fluid consumed (Day 1: r = 0.560, P = 0.010; Day 2: r = 0.445, P = 0.049; Day 3: r = 0.743, P = 0.0001). We conclude that young, native tropical soccer players arrive hypohydrated to training and that they exhibit voluntary dehydration; therefore, enhancing athletes' self-knowledge of sweat loss during training might help them to consume sufficient fluid to match the sweat losses.     

Whose curriculum? Critical notes on integration and entitlement

ABSTRACT

This paper considers the way in which current notions of integration and curriculum entitlement may disadvantage pupils with exceptional needs. An illustrative case of a pupil with profound and multiple learning difficulties is discussed along with general issues of entitlement arising, and the implications for that individual. Through an examination of the effects of the criteria for ‘being educated’ that result from the implementation of the National Curriculum in the UK, we question current perceptions of issues such as normalization, age appropriateness and 'integration’. We use a case study of a child with autism to question whether his educational interests are best served by current notions of integrated education. We suggest a broader notion of education that encompasses rather than contrasts with care, and suggest that curriculum entitlement should involve common curricular principles rather than common curricular content and should not deny within‐child factors. We further suggest that ‘integration’ should be reconceptualized as 'inclusion’ and we query the features that make educational needs ‘special’     

Pedagogical Content Knowledge and the 2003 Science Teacher Preparation Standards for NCATE Accreditation or State Approval

The 2003 National Science Teachers Association Standards for Science Teacher Preparation (NSTA-SSTP) were developed to provide guidelines and expectations for science teacher preparation programs. This article is the fourth in a special JSTE series on accreditation written to assist science teacher educators in meeting the NSTA-SSTP. In this article, the authors discuss pedagogical content knowledge and how this is expressed in the NSTA-SSTP. Included are competencies and examples needed for a science teacher preparation program to document developing pedagogical content knowledge in preservice science teachers.
