From: Benjamin Mako Hill Date: Sun, 6 Mar 2022 04:51:15 +0000 (-0800) Subject: code to create final case discussion grades X-Git-Url: https://code.communitydata.science/coldcallbot-discord.git/commitdiff_plain/78ac188f0487ba413244246181ad90b9a73451d8?hp=35bf83e9f6168af66d16196bf6b455954acaa3e6 code to create final case discussion grades This still needs to be check over but this is new code to build the final grades. Current threshold for minimum questions comes from 1000 simulated classes (simulation.R). --- diff --git a/assessment_and_tracking/compute_final_case_grades.R b/assessment_and_tracking/compute_final_case_grades.R index b26270b..22dae47 100644 --- a/assessment_and_tracking/compute_final_case_grades.R +++ b/assessment_and_tracking/compute_final_case_grades.R @@ -1,72 +1,147 @@ ## load in the data ################################# +myuw <- read.csv("../data/2022_winter_COM_481_A_students.csv", stringsAsFactors=FALSE) -myuw <- read.csv("myuw-COMMLD_570_A_spring_2021_students.csv", stringsAsFactors=FALSE) +current.dir <- getwd() +source("../assessment_and_tracking/track_participation.R") +setwd(current.dir) + +rownames(d) <- d$unique.name +call.list$timestamp <- as.Date(call.list$timestamp) ## class-level variables -question.grades <- c("GOOD"=100, "FAIR"=100-(50/3.3), "WEAK"=100-(50/(3.3)*2)) +question.grades <- c("PLUS"=100, "CHECK"=100-(50/3.3), "MINUS"=100-(50/(3.3)*2)) +missed.question.penalty <- (50/3.3) * 0.2 ## 1/5 of a full point on the GPA scale -source("../assessment_and_tracking/track_participation.R") -setwd("case_grades") +## inspect set the absence threashold +ggplot(d) + aes(x=absences) + geom_histogram(binwidth=1, fill="white",color="black") +## absence.threshold <- median(d$absences) +absence.threshold <- 4 ## TODO talk about this -rownames(d) <- d$unique.name +## inspect and set the questions cutoff +## questions.cutoff <- median(d$num.calls) +## median(d$num.calls) +## questions.cutoff <- nrow(call.list) / nrow(d) ## TODO talk about this +## first these are the people were were not called simply because they got unlucky + + ## this is the 95% percentile based on simulation in simulation.R +questions.cutoff <- 4 ## show the distribution of assessments table(call.list$assessment) prop.table(table(call.list$assessment)) -table(call.list$answered) -prop.table(table(call.list$answered)) + +table(call.list.full$answered) +prop.table(table(call.list.full$answered)) total.questions.asked <- nrow(call.list) -## generate grades +## find out how man questions folks have present/absent for ########################################################## +calls.per.day <- data.frame(day=as.Date(names(table(call.list$timestamp))), + questions.asked=as.numeric(table(call.list$timestamp))) + +## function to return the numbers of calls present for or zero if they +## were absent +calls.for.student.day <- function (day, student.id) { + if (any(absence$unique.name == student.id & absence$date.absent == day)) { + return(0) + } else { + return(calls.per.day$questions.asked[calls.per.day$day == day]) + } +} + +compute.questions.present.for.student <- function (student.id) { + sum(unlist(lapply(unique(calls.per.day$day), calls.for.student.day, student.id))) +} -d$part.grade <- NA +## create new column with number of questions present +d$q.present <- unlist(lapply(d$unique.name, compute.questions.present.for.student)) +d$prop.asked <- d$num.calls / d$q.present + +## generate statistics using these new variables +prop.asks.quantiles <- quantile(d$prop.asked, probs=seq(0,1, 0.01)) +prop.asks.quantiles <- prop.asks.quantiles[!duplicated(prop.asks.quantiles)] + +d$prop.asked.quant <- cut(d$prop.asked, right=FALSE, breaks=c(prop.asks.quantiles, 1), + labels=names(prop.asks.quantiles)[1:(length(prop.asks.quantiles))]) + +## generate grades +########################################################## ## print the median number of questions for (a) everybody and (b) ## people that have been present 75% of the time median(d$num.calls) -questions.cutoff <- median(d$num.calls) -
