Recently, two colleagues and myself published an article in the Journal of Research in Science Teaching (JRST). The Journal of Research in Science Teaching, the official journal of NARST: A Worldwide Organization for Improving Science Teaching and Learning Through Research, publishes reports for science education researchers and practitioners on issues of science teaching and learning and science education policy. Scholarly manuscripts within the domain of the Journal of Research in Science Teaching include, but are not limited to, investigations employing qualitative, ethnographic, historical, survey, philosophical, or case study research approaches; position papers; policy perspectives; critical reviews of the literature; and comments and criticism. It is currently the third highest ranked journal in the field (see Figure 1). -Dr. Petrosino 

Abstract: The fundamental scientific concept of evolution occurring by natural selection is home to many deeply held alternative conceptions and considered difficult to teach. Science teachers’ subject matter knowledge (SMK) and the pedagogical content knowledge (PCK) component of knowledge of students’ conceptions (KOSC) can be valuable resources for helping students learn difficult science concepts such as natural selection. However, little research exists that explores the relationship between science teachers’ SMK and their KOSC on evolution by natural selection. This study explores the relationship between SMK and KOSC through the participation of four biology teachers at a single high school and thus deepens our understanding of the teacher knowledge base. Main data sources are teacher interviews in which each teacher answered SMK-type questions and predicted what their students’ most common alternative conceptions were by using the Conceptual Inventory of Natural Selection (CINS). Other data sources include student responses on the CINS and classroom observations. Findings revealed relative independence between SMK and KOSC, although there is likely a minimum threshold of SMK to recognize student alternative conceptions. However, our work also revealed ways in which teachers were not leveraging their KOSC and suggest potential avenues for future inquiry. # 2016 Wiley Periodicals, Inc.

Resilience to Change- Expert Blind Spot Among Preservice and Inservice Teachers: Beliefs About Algebraic Reasoning and Potential Impact on Engineering Education

The following is a final draft of a paper that will be submitted for publication within the next few months and will also be presented at a national conference focusing on engineering education, algebraic learning and teacher preparation. I'm writing with a colleague of mine from the University of Michigan.  In this study, we examine the differences in teachers’ held perceptions about algebraic representational problems (symbolic, word, and story) between pre-service and in-service teachers participating in a teacher education program. Further, I explore further the expert blind spot in algebraic teaching and its implications for K-12 engineering education and the STEM pipeline.-Dr. Petrosino

Answers to Questions About Choice Students in the Hoboken School District: 166 (total) and 120 of 458 (HHS)

Quick Summary: The latest available NJDOE data indicates there are 166 choice students in the Hoboken School District. Additional data indicates 26% of high school enrollment in Hoboken High School are choice students. 

As regular readers will recall, the Hoboken School District is a receiving district for "choice" students from the surrounding area. But just how many students are there in Hoboken who are "choice" students and how many of them are enrolled in the high school. A fairly simple and straight forward question but one that is not very easy to ascertain. I have received a number of inquiries over the past few days concerning these questions and though that if a few people are interested, perhaps there are many more. 

This post will answer 2 questions. First, how many "choice students" are in the Hoboken School District. Second, what percentage of enrolled students in Hoboken High School are choice students? 

Question 1: The graph below is pretty straight forward and not only shows the number of choice students for the most recent school year (166) but also shows the continued rise of choice students since the 2009-10 school year. 

Chart 1: Number of Choice Students in Hoboken District
2009-10 to 2015-16

Question 2: The second question is how many choice students are in Hoboken High School. I have include some of my data sources (see Chart 2 and Chart 3). According to the latest data, there were 458 total enrolled students in Hoboken High School with 120 of them being "choice" students. Therefore, based on the latest data, roughly 26% of the students in Hoboken High School are non-residents or "choice" students. 

Chart 2: 2015-15 Enrollment District Data- Hoboken School District

Chart 3: Disaggregated Choice Data by Grade 2015-16 School Year 

Comment: While a district cannot "pick and choose" all choice students, the district Board does control the number of choice students admitted to the school district as long as the number admitted is within the upper limit of state approved slots for the district. There is also no available analysis that I know of currently that has examined choice vs resident students on any specific measures.

Free or Reduced Lunch Population Steadily Declines from 86.30% in 1998-99 to 52.55% in 2015-16 for Hoboken Public School District

Figure 1: 1998-2016 Free or Reduced Lunch Percentage
The percentage of students identified as qualifying for Free or Reduced Lunch has declined from 86.30% in 1998-99 to 52.55% in 2015-16 for the Hoboken School District. 

According to Merrian-Webster dictionary white flight is the departure of whites from places (as urban neighborhoods or schools) increasingly or predominantly populated by minorities. Perhaps a more expansive approach to "white flight" might include socioeconomic status or class after all sometimes people use the term "white" as a euphemism for other conditions (class, income) which we may feel uncomfortable discussing. 

So, are charter schools having a segregative impact on the Hoboken Public Schools causing "white flight" as claimed by a number of Hoboken Board of Education members and realized in terms of an exodus of non-free or reduced students (a.k.a. "middle class")?

The short answer is that over the past 18 years the percentage of students identified as qualifying for free or reduced lunch has declined from 86% to 53% (see Figure 1). 

BACKGROUND: Over the past weeks I have received inquiries concerning the Free and Reduced percentages for the Hoboken School District. As many of you pointed out, the data I reported was from 2013-14 and was the most current available from the informative Eduction Law Center website. I have since done additional research and found more updated numbers for the 2015-16 school year. The updated percentages are similar and statistically not very different to 2013-14. I also decided to do a more longitudinal analysis and now have date for the past 18 years. 

For 2015-16 there were a total of 1943 students in the district and 1021 received either free or reduced lunch. This means the percentage of FRL students for 2015-16 in the Hoboken School District was about 53%. 

Figure 2: 2015-16 Hoboken City Enrollment Data
Recall, in 2013-14 the percentage as reported by the Education Law Center was 49%. 

Figure 3: 2013-14 Hoboken City FRL Percentages

I did some additional research and looked up some archival data. 

For 2005-06, about a decade ago, there were a total of 1900 children in the school district and 1491 qualified for either Free or Reduced Lunch. This means the percentage of FRL in 2005-06 in the Hoboken School District was about 78.47%

For 1998-99, the oldest data I could find fairly quickly, there were 2625 children in the school district and 2266 qualified for either free or reduced lunch. This means the percentage of FRL students for 1998-99 in the Hoboken School District was about 86.32%

After finding the 1998-99 data I thought it would be interesting to gather data for EACH year in order to get a more fine grain look at the data over a long stretch of time-- in this case, 18 years. This also compliments an analysis I did previously where we looked at the percentage of students identified as "white" in the Hoboken School District

Summary: "White flight" and segregative impact may be a challenge to convince open minded people and independent third parties when data indicates the percentage of white students have been on an 18 year rise (from @15% to 33%) AND the percentage of students from families meeting criteria for free or reduced lunch have declined significantly (from 86% to 53%) over the same time period in the Hoboken School District. 

“they’re (charter schools) fostering white flight, and they’re bankrupting us,” the city’s school board head charged in a Wednesday interview. “We are creating separate but equal school systems,” warned Hoboken Board of Education president Leon Gold -Salon (3/14/14)

Further Clarification: Some regular readers of this blog pointed out that further clarification might be needed. I agree. It is important to understand that this data on Free or Reduced Lunch eligibility (Figure 1) is at the full district level and not disaggregated. Grade by grade analysis (i.e. disaggregated)  reveals different and also concerning trends of the Hoboken School District's inability to retain the non Free or Reduced eligibility population of students it has enrolled in the early grades (Figures 6 and 7 below). In short, the students categorized as non Free or Reduced Lunch eligible are primarily, although not exclusively, in the early grades. What percentage of the non Free or Reduced eligibility population of students that have left the Hoboken School District are also considered white is an interesting question but outside the focus of this particular post.

White Flight Not Evident in 18 Year Longitudinal Analysis of the Hoboken Public School District Despite Claims by Advocates

Figure 1: Percentage of Students Defined as White in
Hoboken School District (1998-2016)
Click to Enlarge
According to Merrian-Webster dictionary white flight is the departure of whites from places (as urban neighborhoods or schools) increasingly or predominantly populated by minorities. 
Are charter schools having a segregative impact on the Hoboken Public Schools causing "white flight" as claimed by a number of Hoboken Board of Education members

One way to determine if white flight is taking place is to document the decrease in white students in the school district. It would make sense that if white flight was occurring, white students would be leaving the district and would be making up a smaller and smaller percentage of the student enrollment in the district. 

When we look at the data over an 18 year span, we find the percentage of students designated as white is actually increasing in the Hoboken Public School District...and significantly(!)

In fact, the percentage of white students in the Hoboken Public School District has risen from 14.98% in 2000-01 to 33.2 % in 2015-16- an increase of over 120%. Moreover, since the Hola Dual Language School was founded in 2010-11 the percentage of white students in the Hoboken School District has risen from 22% to 33%.

The trend line (dotted arrow- Figure 1) clearly shows the percentage of white students in the Hoboken Public School District has been on the rise for the past two decades with no evidence of a plateau. White flight, as measured by the decline in the percentage of white students in the Hoboken School District, is not taking place in the Hoboken School District and in fact, has seen a steady increase since 1998-99.
