1 Abstract

In the last eight years, we have taught a General Chemistry sophomore course. During all this time, while the chemistry content has not changed significantly, the forms of delivery and assessment have been evolving towards better pedagogies of engagment and towards a clearer assessment of learning objectives.

2 Overview Final Course grades

Let’s just look at how students have performed in the two GC semesters by looking at their final grade in different semesters. (The final grades from Fall12-Spring13 is not correct, not sure why, that being said, you’ll see that the cohort Fall2012 is the only one that consistently scores lower in freshman-GPA and Highschool rank.)

IMPORTANT: We will see statistical significance between years and other demographics when analyzing the final percent grade. However, when we analyze the letter grade, those significances disappear

It does seem like the cohort Fall 2011 - Spring 2012 did significantly different than any other year.

2.4 Other grades besides final grade

2.4.1 Letter grades

I converted the letter grades into the 4-scale. The plot should only show 4, 3.66, 3.33, 3… but it seems to add more variability… it needs to be fixed… or just run anova on the letter grades (once I learn how to do that)

2.4.2 Semester exams and previous exams

The final exam is a second opportunity for students to improve their semester exams. Let’s measure how exams score and improvement evolved through the years.

This is plots the increment

There’s something funky about some of these numbers. Fall 2014 doesn’t seem to apply the >40% rule, which I actually implemented.

So let’s check that I obtain the same result if I plot grade exams from BoSCO data

2.4.3 Specific homework quizzes

TODO: Check ~/Research/R/myCourses theres a lot of work there

Also, you need to merge the demographics that you are using and include letter grade and gender as well as exams and homework… it may be problematic to add F17/S18 because I’m missing so much DEM_

3 Predictors of performance in Chemistry

There are different variables that we want to look at. Performance factors such as ACT scores or GPA or High School rank , as well as demographic factors such as ethnicity, first-year generation

3.1 Math ACT is a good predictor

ACT Math - Fall sophomore
group1 n mean sd median trimmed mad min max range
X11 Fall 2011 64 24.75 3.50 24.5 24.67 3.71 18 33 15

X15 Fall 2015 57 24.72 3.19 24.0 24.70 2.97 18 32 14
X16 Fall 2016 32 24.94 2.64 25.0 24.96 2.97 19 30 11
ACT Math - Spring sophomore
group1 n mean sd median trimmed mad min max range
X11 Spring 2011 16 25.88 4.18 25.5 25.79 3.71 19 34 15
X12 Spring 2012 42 25.57 3.47 25.0 25.56 2.97 18 33 15
X13 Spring 2013 44 26.23 4.15 26.0 26.17 4.45 18 34 16
X14 Spring 2014 52 24.90 2.76 25.0 25.17 2.97 18 29 11
X15 Spring 2015 58 26.10 3.36 26.0 26.04 2.97 19 34 15
X16 Spring 2016 42 25.10 3.27 25.0 25.00 2.97 18 32 14
X17 Spring 2017 33 25.27 2.47 26.0 25.30 2.97 21 30 9

We see that the second semester is a subselection of the first semester with a higher ACT math score. Therefore, we can just use GenChem1 for the analysis.

3.1.1 Was math ACT different through the years?

As we can see below. There is no significant difference in ACT throughout the years

3.1.2 Correlation models: ACT vs GenChem1

so, pretty crappy r-squared for both 0.2042773 and 0.1569021, respectively. We need to find a better predictor. Let’s see cumulative GPA before enrolling

3.2 Previous GPA is a better predictor

While ACT.Math historically seems to correlate well, since we’re teaching sophomores, previous GPA is even a better predictor

3.2.2 Correlation models: Prev. GPA vs GenChem grades

So when we plot previous GPA (typicall first year GPA) against final grade

so, better r-squared for both 0.656591 and 0.5840838, respectively

3.3 Is Highschool performance relevant?

For large schools, Highschool ranking can be used as a better measurement than HS GPA… also, HS-GPA is currently unavailable :). The units are given in percentile, so the higher the better

so, crappy r-squared for both 0.1667476 and 0.0552476, respectively

3.4 Conclusions about indicators of performance

4 Demographics

Given the good correlation given above between previous GPA and final grade, let’s then analyze how students of different demographics perform in chemistry when compared to their incoming GPA. In other words, instead of comparing how first-generation vs non-first-generation do, it is more interesting to see how considering their college readiness (as desribed by GPA) how they did in GenChem

4.1 Sex

Look at how previous GPA and GenChem grades is among gender identities

1st year GPA and Sex
group1 n mean sd median trimmed mad min max range
X11 F 286 3.08 0.45 3.06 3.08 0.48 1.88 4 2.12
X12 M 117 3.00 0.53 3.04 3.01 0.49 1.33 4 2.67
ACT math and Sex
group1 n mean sd median trimmed mad min max range
X11 F 270 24.61 3.09 25 24.61 2.97 17 34 17
X12 M 111 25.82 3.71 26 25.83 2.97 17 34 17
HS rank and Sex
group1 n mean sd median trimmed mad min max range
X11 F 239 81.02 14.21 84.0 82.64 11.86 25 99 74
X12 M 96 74.40 16.42 76.5 75.46 17.05 20 99 79

From the above, we can see that females come to GenChem with very slightly higher GPA and remarkably better HS ranking, but with a lower ACT-math score. Also, males have a broader range of values and higher standard deviation, this tell us that male performance may not be treated as a single group, and it may require a further finer classification. In any case, How will these three factors affect their performance in GenChem?

GenChem1 grade and Sex
group1 n mean sd median trimmed mad min max range
X11 F 289 79.74 9.84 81.0 80.49 9.49 42.50 98.78 56.28
X12 M 120 80.88 12.12 82.1 82.36 11.15 40.52 97.14 56.62
GenChem2 grade and Sex
group1 n mean sd median trimmed mad min max range
X11 F 196 78.18 10.51 79.28 78.88 9.62 38.20 97.50 59.30
X12 M 102 80.31 10.19 80.57 80.76 13.00 56.39 97.22 40.83

4.1.1 Comparing the two genders each year

While it may look like males do better than females, even though females came with better GPA and HS ranking, there is actually no significant difference when compared the two groups in general.

However, when the two groups are compared each semester we notice that Fall 2011 is the only semester with a significant difference between sexes.

4.1.2 Performance by each gender through the years

Before we jump into conclusions, however, we may need to look into how the females in Fall 2011 performed compared to other semester’s females.

We saw that females had performed significantly lower in Fall2011, and almost significantly higher in Fall2013 than males. However, we see that these differences may also be explained by the differences with the incoming GPAs, but not by HS ranking. Also, many students lack HS Ranking so the statistics may be lacking.

4.2 Students of color

Let’s compare the GPA before enrolling in GenChem for students of color vs the rest.

1st year GPA and Student of Color: Y/N
group1 n mean sd median trimmed mad min max range
X11 N 340 3.09 0.47 3.11 3.10 0.47 1.33 4.00 2.67
X12 Y 73 2.84 0.46 2.78 2.82 0.43 1.90 3.97 2.07
GenChem1 grade and Student of Color: Y/N
group1 n mean sd median trimmed mad min max range
X11 N 348 81.06 10.20 82.34 82.13 8.65 40.52 98.78 58.27
X12 Y 73 74.67 10.48 75.30 74.58 12.04 43.47 96.02 52.56
GenChem2 grade and Student of Color: Y/N
group1 n mean sd median trimmed mad min max range
X11 N 260 79.13 10.33 79.74 79.75 10.53 43.7 97.5 53.8
X12 Y 49 74.44 12.76 72.95 75.31 9.87 35.6 96.7 61.1

Graphically we can see below what the means above already tell us, while people of color do worse in GenChem1 than whites, they were already doing worse before enrolling.

4.2.1 Statistical analysis of performance students of color in GenChem1

From above we can see that even though students of color perform below the average in GenChem1, they already come with a lower “college readiness”. In other words, the cause for lower performance of students of color must be found elsewhere. For example, one could look at Highschool data such as ACT scores or Highschool rank.

4.2.2 Different ethnicities

Let’s see what we mean by students of color, and how they did during their first year

1st year GPA for different ethnicities
group1 n mean sd median trimmed mad min max range
X11 0 NaN NA NA NaN NA Inf -Inf -Inf
X12 Am. Indian 5 2.74 0.36 2.62 2.74 0.43 2.33 3.23 0.90
X13 Asian 38 2.88 0.47 2.81 2.86 0.36 1.90 3.97 2.07
X14 Black 29 2.96 0.50 2.89 2.95 0.56 2.12 3.95 1.83
X15 Hawaiian 1 3.11 NA 3.11 3.11 0.00 3.11 3.11 0.00
X16 Hispanic 13 2.78 0.38 2.70 2.76 0.36 2.27 3.47 1.20
X17 NS 3 2.72 0.66 2.37 2.72 0.07 2.32 3.48 1.16
X18 White 324 3.10 0.47 3.11 3.11 0.47 1.33 4.00 2.67

We can also run an anova among different ethnicities, but in any case it’s hard to do statistics on such small numbers maybe only black and asian are large enough to be compared with whites.

4.3 First generation students

Let’s compare the GPA before enrolling in GenChem for 1st generation vs the rest. Notice for how many people we have information (a total of 421 students in Genchem1 and 309 in GenChem2)

4.3.1 Statistical analysis of performance 1st generation in GenChem1

First generation seem to do slightly better at UMR than or the same than non-first gens. Are they coming in with equal preparation?

It seems that the first generation students we’ve been accepting are already better prepared than the non-first generation.
